Best Prices for Ubiquiti Unifi Access Points Sale in Nairobi Kenya

05/12/2021 12:08 UniFi is Ubiquiti’s line of networking equipment with different models of wireless access points, routers, switches, security cameras, controller appliances, VoIP phones, and access control products. UniFi equipment exists between enterprise and cheap home networking gear. It’s a nice middle ground, offering more flexibility and features than most consumer-grade brands, but lacking the expense and complexity of enterprise. UniFi networks come in all shapes in sizes: from a small apartment, up to thousands of devices in a stadium, and a lot of networks in between. You choose the pieces that you need, and you are not required to have the full UniFi stack. You can start with one device and build it out over time. If you only need Wi-Fi, their access points can be uplinked to any switch, and served packets from any router. If you need a managed switch or security gateway, Ubiquiti makes those too. There are benefits to having all the pieces, but it’s not necessary.

UniFi OS Software and Applications

Software-Defined Networking

Software-defined networking can be a meaningless word, but the basic definition is that the administration is done in software, separate from the actual networking equipment. With UniFi, you use the UniFi network controller. This is free software that can run on Windows, macOS or Linux. You can run the software on any PC you have on a physical server, or in a VM or Docker container. It also runs inside the UniFi Dream Machines and UniFi Cloud Keys. The controller software is used for configuring and monitoring your UniFi network. If you need to make changes to your settings, add additional devices, or upgrade firmware, you’ll do all of that through the UniFi controller. A few things can be done on the command line via SSH, but in general, UniFi devices are meant to be managed through the controller. The primary way of accessing the software is in a web browser. Ubiquiti also make mobile applications for Android and iOS which have some of the functions found on the web interface. Here are some of the bestselling UniFi wireless access points:
  • AC-Lite: The do-everything workhorse. Unless you are trying to push gigabit speeds or have some really heavy wireless needs in mind, this is a good default option.
  • UniFi 6 Lite: The smallest, cheapest Wi-Fi 6 AP. The new baseline.
  • AC-LR: LR stands for long range. Features a better antenna that can reach further distances than the AC-Lite. It’s a good option if you are trying to cover the far corners of a house. The LR is only a small step up in price from the lite, and is another good default option.
  • UniFi 6 LR: The long range version of the UniFi 6 Lite. Steps up to 4×4 5 GHz radio, allowing for longer range and higher speeds than the 6 Lite.
  • AC-Mesh: If you need longer-range mesh or outdoor coverage, this is the one to get.
  • AC-BeaconHD: If Ethernet isn’t an option, this is the best indoor mesh AP they offer.
  • AC-nanoHD: Newer than the Pro, this is the cheapest 802.11ac Wave 2 access point they make. If you have modern devices that support multiple radio chains on 5 GHz, you can get some fast throughput. 2.4 GHz performance isn’t as strong as the Pro, however.
  • AC-FlexHD: Same radios and capabilities as the nanoHD in a different form factor.
  • AC-HD: For really high density and/or maximum throughput. Only buy this if you have the need, or the cash to burn. The HD has the best 2.4 and 5 GHz performance I’d recommend for home use. The only step up from the HD is the UWB-XG, which is intended more for places like an auditorium or sports venues (hundreds or thousands of devices in a small area).
And unless you have a specific need for them, you can also ignore most of the specialty models.
  • UAP-AC-EDU adds a built in loudspeaker and is EoL.
  • UAP-AC-SHD adds an extra radio dedicated to security tasks and RF monitoring, meant for dense and secure environments like a bank, or a hospital.
  • The XG series (UAP-XG and UWB-XG) are overkill for 99.99% of home networks – more on those later.
  • IW stands for In-Wall. In-Wall APs can be used if mounting a traditional access point isn’t an option. Ethernet should still be run to these, but they also have the benefit of providing two or four Ethernet ports for other downstream devices, thanks to a small built-in switch.
  • M stands for mesh. Mesh APs are what you want if you are mounting outdoors. The mesh models (and all 2nd generation or newer UniFi APs) allow you to extend a network without requiring Ethernet cabling, using a power adapter and wireless backhaul. Wireless backhaul will not perform as well as wired, but they can be the best option for certain situations.
Essentially they act as a wireless bridge when you are connected to it. One radio talks to your device, while the other relays that to the next closest AP. This is why wireless backhaul will generally have higher latency and lower speeds than using Ethernet.

802.11AC WAVE 1 VS. WAVE 2

The Lite, LR and Pro models are all 802.11ac Wave 1. The HD models are all 802.11ac Wave 2. Wave 2 brings a few majors changes which allow for higher performance. Wave 1 AP’s can only use SU-MIMO (Single-User, Multiple Input, Multiple Output) to communicate with only one client at a time. Wave 2 APs can use MU-MIMO (Multi-User, Multiple Input, Multiple Output) to communicate with multiple clients at the same time — significantly increasing multi-user throughput. MU-MIMO also increases wireless performance and/or serves more clients at the same performance level. At any single time, a 4×4 Wave 2 AP can communicate with the following:
  • Four 1×1 clients
  • Two 2×2 clients
  • One 2×2 client and two 1×1 clients
  • One 3×3 client and one 1×1 client
Another benefit of Wave 2 is that up to four spatial streams are available, and more channels can be bonded together. Both of those feature’s help achieve higher speeds. Deciding if the added costs and abilities are worth it is up to you. ANTENNA DIFFERENCES One more thing to keep in mind — while a lot of models have equivalent radio performance, there are differences in their antennas, and how those antennas perform. Generally speaking, the LR, mesh and HD models have higher-gain, and more sensitive antennas. Equivalent radios with better antennas lead to better performance. If you want maximum performance in one area, you can have one Pro or HD covering that, and use AC-Lite’s or mesh APs to extend the network into less used areas. Alternatively, if you want to expand coverage in the future, you do not need to match the AP’s you currently have. You can add any of them at anytime, anywhere you need them.

Power Distribution Unit in Kenya

07/22/2020 7:50

A power distribution unit (PDU) in Kenya or mains distribution unit (MDU) is a device fitted with multiple outputs designed to distribute electric power, especially to racks of computers and networking equipment located within a data centre. Data centres face challenges in power protection and management solutions. This is why many data centres rely on PDU monitoring to improve efficiency, uptime, and growth.

Rack mount Power Distribution Unit in Kenya

A 10-outlet rack-mount PDU (front  from A2Z Africa Kenya), connected to a UPS (bottom unit on right). PDUs vary from simple and inexpensive rack-mounted power strips to larger floor-mounted PDUs with multiple functions including power filtering to improve power quality, intelligent load balancing, and remote monitoring and control by LAN or SNMP. This kind of PDU placement offers intelligent capabilities such as power metering at the inlet, outlet, and PDU branch circuit level and support for environment sensors.

Cabinet Power Distribution Unit in Kenya

In data centres, larger PDUs are needed to power multiple server cabinets. Each server cabinet or row of cabinets may require multiple high current circuits, possibly from different phases of incoming power or different UPSs. Standalone cabinet PDUs are self-contained units that include main circuit breakers, individual circuit breakers, and power monitoring panels. The cabinet provides internal bus bars for neutral and grounding. Prepunched top and bottom panels allow for safe cable entry.

Portable Power Distribution Unit in Kenya

In homes and offices, power distribution unit may also refer to a power strip or similar device for consumer use. These units are usually portable.

Siemon’s PowerMax line of PDUs range from basic and metered for simple and cost-effective power distribution, to a full line of intelligent PDUs that deliver real time power information with varying degrees of intelligent functionality for valuable troubleshooting, control and monitoring of power usage, capacity and environmental conditions.

Basic PDUs

Basic PDUs offer a lower-cost alternative for every day, reliable power distribution when advanced features are not required, providing a robust yet economical means to distribute power to IT equipment.

Metered PDUs

Metered PDUs provide local visual monitoring capability through a built-in LED meter that displays real-time power data. Metered PDUs are a cost-effective alternative for providing more intelligence than basic PDUs.

Monitored PDU

Monitored PDUs enable remote monitoring at an aggregate, device-level via an Ethernet port, generating a smaller quantity of information to simplify management.

Switched PDUs

Switched Power Distribution Unit in Kenya

Switched PDUs combine total monitoring with outlet-level switching that enables users to remotely control individual receptacles, allowing equipment to be restarted or remotely shut down. Switched PDUs offer the ability to configure outlets into up to six groups and assign user group access to specific outlets groups.

Smart PDUs Power Distribution Unit in Kenya

Smart PDUs offer a higher level of monitoring at the device or outlet-level via an Ethernet port. Smart PDUs offer the ability to configure outlets into up to six groups and assign user group access to specific outlets groups.

Managed PDUs Power Distribution Unit in Kenya

Managed PDUs offer the highest level of control and monitoring with outlet-level monitoring and outlet-level switching that enable users to remotely monitor and control individual receptacles. Managed PDUs offer the ability to configure outlets into up to six groups and assign user group access to specific outlets groups.

How to extend WiFi coverage using an Ubiquiti NanoStation

07/6/2020 14:53

In this guide I will show you how to extend your WiFi range and include a separate building using an Ubiquiti NanoStation.

The problem

With no data-hungry teenagers left in the house, my dad’s 200GB Telstra Cable plan has lately gone unused, himself only using about 10% of the data allowance each month.

His neighbours are a young family who have been making do with a cheap Vodafone 3G USB connection, pulling about 2-3Mbps download on a good day, when “the wind blows in the right direction” as his neighbour often says.

It doesn’t take a rocket scientist to see it made sense to share his solid 30Mbps connection between the two houses.

So after fiddling about with a Netgear router set in WDS mode (a form of wireless bridging) for a few days with constant dropouts and slow connection speed, it was time to set up something more substantial.

Normally extending WiFi with another access point set in WDS mode works reasonably well, but with both houses being double-brick construction, it blocks most of the signal reaching the second access point.

The solution

We decided to install a directional outdoor WiFi access point on the side of my dad’s house facing his neighbour’s house.

When it comes to this type of equipment, there’s only one name you need to know – Ubiquiti.

We chose the Ubiquiti NanoStation because it has a 60 degree transmission angle, an inbuilt 600mW amplifier, and ~15km range – this unit certainly packed the punch required to penetrate the walls.

Of course set to it’s maximum output the unit would have covered half the suburb, so the unit was turned down to a more appropriate strength.

Equipment required

To complete this type of installation you will need:

  • NanoStation M2 or M2 LOCO
  • 2 sets of Ethernet cable
  • Mounting pole or bracket
  • Basic tools (drill, pliers, etc)
sharing internet with ubiquiti nanostation what equipment do i need

If you’re not familiar with Power-over-Ethernet (PoE), it’s a brilliant technology that allows sending low voltage (24V) over standard Ethernet cable to power devices like our NanoStation.

The Australian 240V plug and PoE injector are supplied as part of the Ubiquiti NanoStation kit.

The PoE injector takes our standard Ethernet connection from the modem/router plugged into the LAN port as its input, adds 24V/1A DC, and pumps it into the outgoing PoE port where we will be plugging a length of standard Ethernet cable in to connect the NanoStation.

In order to isolate the NanoStation’s WiFi from the cable modem’s own WiFi signal (to limit interference), the best spot for the installation was outside the house. Ideally it would have been best to place it on the outside of the brick wall, but we opted for the easier choice and mounted it on a wooden board.

Most of the area to be covered was only 50-70m away from this position.

As the NanoStation is designed for pole mounting, it’s integrated bracket is curved and has a slot for securing with the supplied zip ties.

While we thought about dropping down the hardware store to grab a short length of polypipe and some brackets, a bit of treated timber that was lying around did the job just fine.

As the antenna had to be faced in the direction of the neighbours house, the NanoStation was mounted at a slight angle.

Once mounted correctly, the 10m Ethernet cable was secured in place using cable clips and routed back inside the house to the cable modem, and plugged in to the PoE port on the Power-over-Ethernet injector.

Configuring your NanoStation

Now that the hardware has been completely installed, it’s time to configure the NanoStation to act as a WiFi Access Point.

While the device can be configured over the network, it’s often easier to perform configuration when the LAN cable is plugged directly into the Ethernet jack on your computer.

Configuration is performed using your web browser by typing in

You’ll get a warning pop up stating that the device has presented an invalid SSL certificate due to the certificate being self-signed and not issued by a CA. This is normal, so just hit accept/continue.

You’ll then need to log in with the default username and password of “ubnt”.

Configure the Wireless tab

The first step is to configure the wireless tab so the NanoStation acts as a WiFi Access Point.

Change the settings according to the below picture. Be sure to set the device up with WPA2 security and an appropriate WiFi password here.

You can also use this tab to adjust the power output should you wish to cover a smaller area.

The default channel bandwidth is 40MHz, but some older devices such as wireless printers and mobile phones cannot operate on 40MHz, so we’ve changed it to 20MHz in this setup.

Turn off airMAX

Navigate to the left-most tab (with the Ubiquiti logo) and uncheck the airMAX checkbox to disable Ubiquiti’s proprietary airMAX protocol (a special MIMO TDMA multiplexing technique that allows communication between two or more Ubiquiti devices).

You won’t be able to untick the box until the wireless tab has been completely configured.

disable airmax protocol airos 5.5

Configure Network Settings

Finally it’s time to configure the network settings to reflect that of your existing network and modem.

In our case the Telstra Cable modem is located at with a subnet mask of, meaning all our devices are restricted to the 192.168.0.XXX subnet.

This means that we’ve had to change the default to

As we want the cable modem to continue controlling the network, we’re setting the NanoStation to Bridge mode, and then assigning the Default Gateway and DNS IP addresses to the address of the modem (

The secondary DNS server is set to (Google’s DNS server), but this isn’t important. Of course these are our network settings, your settings will undoubtedly be different, so make sure you configure them accordingly.

The Results

On the normal home WiFi network (BigPond3035) sitting 1 metre from the cable modem, speeds typically range between 30-35Mbps and latency between 20-40ms.

Next door in the neighbours house, speeds ranged from 20-30Mbps, with best speeds in the middle of the house away from the brick walls.

Given the short distance, we didn’t need to fine tune any settings or adjust the angle of the NanoStation, if anything the system was still a bit too powerful despite halving the output power.

All Ubiquiti equipment is incredibly versatile, their M2 (2.4GHz) models are most popular for installations requiring long range bridging, extending WiFi coverage, AP-Repeater scenarios requiring the use of 802.11b/g/n, and much more.

Their M5 (5.8GHz) models are preferred for short and long range bridging (P2P, P2MP, hybrid) as there’s less interference on the 5.8GHz band, and can also network with UE operating on 802.11a/n.

For this type of short range installation I’d suggest using the NanoStation LOCO, I simply chose the standard NanoStation and turned the power down to keep the WiFi footprint as small as possible, while still penetrating through the double-brick.

Consequently I could remain connected to the WiFi several hundred metres down the street (as far as I could bother walking), but with WPA2 encryption (and internal security that would make a CISSP proud) – I’m not worried about wardriving.

That’s it – over to you!

Improving alarm services with video verification

06/20/2020 15:05

“Responding to false alarms can be a big drain on resources. With Hikvision’s reliable solution for Intrusion Verification as a Service, you can immediately access high-quality video clips of the scene – helping you confirm if the alarm is real, saving you time and costs while also providing better services to your customers.”

False alarms are a serious problem for the security industry. According to the analyst firm IHS Markit, between 90 and 95 percent of reported intruder alarms turn out to be false  – making them a waste of time, potentially costly for businesses, and a strain on any emergency services that are called out in response.

To address this, some alarm companies are using video verification: live footage of the event which triggered the alarm. This should enable users to visually verify the source of the alarm, and identify false alarms before any resources are dispatched. Law enforcement teams may also use the video as evidence for further investigation where necessary.

However, most video verification systems on the market typically send users low resolution, static imagery of the alarm event. This does not give users the quality of information they need for verification, nor for further police investigation.

The solution: Intrusion Verification as a Service (IVaaS)
Hikvision’s intruder alarm system enables the pioneering Intrusion Verification as a Service, which seamlessly unites video with cutting-edge intrusion detection capabilities in a single platform. Through this high quality video-based solution, users have access to reliable video verification for the first time.

Quality alarm footage, delivered instantly
Intrusion Verification as a Service gives users high-quality CCTV footage of intruders before and after an alarm is triggered. When the alarm trips, the AXHub isolates seven seconds of video: the five seconds before the alarm sounded, and two seconds post alarm. It then instantly delivers those video clips directly to the user through whichever method suits them best: email, an alert on the Hik-Connect app, to Hikvision’s iVMS management software, or directly to a central monitoring station (CMS).

Faster decision making
By sending live video in real-time, the system allows users to verify the trigger of the alarm immediately. In turn, this enables a response team or emergency services to be dispatched to the scene very quickly if necessary.

Full remote control
Compatibility with the Hik-Connect app gives users full control of the alarm from their cell phone. Users can receive mobile push notifications of the alarm sounding, and also in the event that any cameras are compromised. They can also arm, disarm and monitor the alarm via the app.

A reliable intrusion verification solution for residential and commercial properties
The high sensitivity transceivers in the AXHub’s panels and sensors boost the wireless range, making this ideal for residential or small commercial applications.

Get a clearer picture of what’s really happening
To discover how Hikvision’s pioneering solution for high quality Intrusion Verification as a Service can help you avoid false alarms, save time, and boost your responsiveness to incidents, contact Hikvision today.

Hikvision AXHub provides a solution for IVaaS that helps security professionals target new market applications to grow and maximise their business potential. To learn more about the Hikvision AX-Series.

Key features of the AXHub intruder alarm system
• Wireless or direct camera connection. The system can either link to Hikvision cameras wirelessly via the cloud, or up to two cameras via direct connection to the hub itself.
• Rapid switching to live video. Upon viewing the video clips, users can easily switch straight to live streams for additional verification of what is happening at the site.
• No service disruption in an outage. Video clips are still available in the event of loss of power or internet connection.
• Small panel for discreet indoor installation. In the event that the alarm and the cameras become damaged, this ensures those videos that were recorded are still streamed and stored safely.
• Support a full range of wireless security  peripherals. The AXHub is compatible with any Hikvision network camera or intrusion device, including internal and external detectors, contacts, keyfobs, life safety sensors and many more.


Tips to help you identify brand new laptop from a refurbished one

03/6/2020 16:09

 laptop that has been returned to the retailer or the manufacturer due to a defect covered in the warranty or on expiry of the lease agreement can be repaired and reconditioned to an almost ‘brand new status’. Legally they are not new and are known as refurbished laptops or simply refurbs.

Most Unscrupulous traders are reselling refurbished laptops to unsuspecting customers as ‘new’ to maximize their profits.

Laptops unlike cars do not have odometers to indicate ‘mileage’, so it is upon you to carry out due diligence to identify the condition of the Laptop you intend to acquire.

Inspect the surface of the laptop for scratches and feel the keyboard texture. Frequent fingertip contact overtime will make the buttons smooth and shiny

Check laptop screws if you find traces on them you should realize it was opened before.

Inspect the screen or the display for small wear marks as this are very hard to refurbish

The next ‘crude’ test is a bit subjective as it involves smelling the surface of the computer. New laptops have an irritating smell of industrial cleaning agent. Hand refurbished Machines use home cleaning agents which have a fragrance and leaves the notebook surface creamy

Check the Laptop serial number at the back of the machine or in the battery compartment depending on the laptop model.

Open command prompt and type c:>wmic bios get serial number, compare the BIOS serial number with the chassis serial number. If this is not the same the machine may be a refurb. You can also visit the manufacturer’s website and punch in the serial number to indicate the status of the laptop. This feature works for specific laptops.

Generally factory refurbished laptops have their serial number ending with letter ‘R’ E.g. CN174UA#ABA is the product number for a new notebook and CN174UAR#ABA is the product number for a refurbished notebook.

You can also check the back of the laptop for labels such as ‘This is a refurbished laptop and contains used parts’

Check general laptop attachment/peripherals/additions such as Driver CD, Manuals and brochures

Refurbs have a shorter warranty period of 3 months.

Refurbs are also a good bargain if you want to acquire a powerful Laptop at a reasonable price but it is morally right for the vendor to disclose the status of the laptop.

Giganet Cat 6 UTP/FTP CABLE in Kenya

02/12/2020 14:40

Giganet offers end to end cabling solutions that are manufactured and designed by industry experts who have many years of knowledge and experience on infrastructure cabling solutions. Gigante brand has strict quality control and an installer in mind should ensure performance and ease of termination.

The giganet fiber and copper systems support full convergence in an ever demanding workplace. Giganet Kenya is best priced and exceeds international cabling standards.

Giganet Kenya provides a comprehensive range of cables, cabinets, patch codes and enclosures that can be used in the telecommunication and computer industry.  Giganet products are backed by warranty, support and training.

Giganet Cable shielding

Cable shielding acts as a barrier that protects the cable from external threats, such as electrical interference (EMI) and RFI (radio frequency interference). It also prevents cable signals from interfering with surrounding cables and equipment.

STP Cable

Shielded cables are used in areas such as factory floors with high concentration of equipment and secure communication applications. Shielded cable today is prevalent in diverse applications including education, healthcare and government.

When selecting Giganet shielded cable, you need to consider:

  • Flexibility
  • Shielding effectiveness
  • Ease of connecting

Once you know how important each of these things is to you, you’ll know which shielded cable type will work best.

There are many acronyms used to describe shielded cables, from STP to F/FTP; while many are often used synonymously, nearly all of them have different meanings


An overall foil shield (F) with unscreened twisted pairs (UTP)

    This cable is very much like common UTP cable, with the addition of foil underneath the main cable jacket. Another common name for this cable is “FTP.” F/UTP cables are common in 10GBaseT applications. They’re easier to terminate  but they aren’t quite as flexible because the foil tends to be stiffer.

Giganet F/UTP is used in high frequency applications that needs some flexibility.


An overall braid screen (S) with unscreened twisted pairs (UTP)

    This is occasionally referred to as an STP cable, but beware: There are other shielded cables among this list that may also claim this term. To be sure, always check to see whether your cable will have any kind of overall barrier and whether the individual pairs have their own shield.

Use S/UTP in low-frequency applications that require some cable flexibility and easy connectorization.


Both an overall braid screen (S) and foil shield (F) with unscreened twisted pairs (UTP)

    This cable is also occasionally referred to as an “STP cable.” Cables with an overall braided screen are very effective at preventing EMI from entering or exiting the cable.

  Use SF/UTP cable when you need protection from low- and high-frequency noise interference.


    An overall braid screen (S) with foil screened twisted pairs (FTP)

    The “shield” underneath the jacket is a braid, and each individual pair is surrounded by its own foil barrier. The purpose of the additional foil on individual pairs is to limit the amount of crosstalk between them. This type of cable can be harder to install because of the amount of metal that must be removed to install a connector. The braid and stranded conductors inside help maintain flexibility fairly well.

    Use S/FTP cable when you need protection from low- and high-frequency noise interference. It’s easy to install and is moderately flexible. All primaries are foiled.


An overall foil shield (F) with foil screened twisted pairs (FTP). Similar to F/UTP cables, these shielded cables are commonly used in 10GBaseT applications.

    Use F/FTP cable when you need high levels of shielding from high-frequency noise interference and aren’t worried about ease of installation (it offers little to no flexibility) or the time it takes to install connectors.


No overall shielding or braid (U) with foil screened twisted pairs (FTP). This type of shielded cable is commonly used in 10GBaseT applications as well. Use F/UTP in high-frequency applications that require some cable flexibility.
