HD Network testers are devices that are mainly used to test CCTV cameras for their functionality. CC cameras can be the types of IP, Analogue, or HD. For IP, the video images are compressed before it is transmitted over the network in digital format. In HD, the videos are wired back to the recorder. In any case, these need to be tested during installation and maintenance. 

Once installed, the technicians check if the cameras work properly, if they can be zoomed in and out, turned to the required directions, and inspect for troubleshoots in the network or in the cable. It is generally used as testing equipment by technicians and to make sure the cameras point in the right direction and if they cover all the areas required.

How does it work?

Once the cameras are fixed, this device can be connected to it and a power supply is provided to the camera from the device. Later if it is an IP camera, an IP network can be set through this temporarily to check the view of the cameras.

If the cameras are HD, the cables can be connected to the device and the view can be checked and corrected if needed. The cable transmission can also be checked on the device. It is very handy and makes the installation process easier.

What is it needed for?

A Network tester is an important gadget to assist a technician. Most of the time, installations happen before the full functioning of a building starts. This device helps technicians to connect the cameras easily, turn them on and check their positioning. This will remove the requirement to revisit and reposition the cameras later. You can make sure everything is set correctly right at the time of installation. 

There are different types of testers available in the market. Many have the latest updates and features which help to check both IP and HD cameras with a single device, making it easier and cost-effective for technicians.
