An overview about the CCTV Cameras

What is it?

CCTV (closed-circuit television) cameras are surveillance devices used in heating, ventilation, and air conditioning (HVAC) systems to monitor and record video footage of a building's interior or exterior.

Why we use it?

We use CCTV cameras to increase security, prevent theft or vandalism, and improve safety by monitoring activity in and around buildings.

How it works?

A CCTV camera typically captures video footage and sends it to a digital recorder or network video recorder (NVR), which can then store the footage for future reference or stream it live over a network.

Major brands that manufacture it

Some of the major brands that manufacture CCTV cameras include Hikvision, Dahua, Axis Communications, and Bosch Security Systems.


There are different types of CCTV cameras, including dome, bullet, and PTZ (pan-tilt-zoom) models, with various resolutions and image sensors to fit different applications.

How do we select it?

When selecting a CCTV camera, consider factors such as resolution, image quality, field of view, connectivity options, and compatibility with your recording and streaming systems.

How to install it?

CCTV cameras should be installed according to the manufacturer's recommendations. They should be securely mounted using appropriate fittings or adapters, and any necessary wiring connections should be made to the digital recorder or NVR.

Wire connections required to receive the signals

The wire connections required to receive signals from a CCTV camera may vary depending on the specific device and recording or streaming system. Typically, they will require electrical wires that connect to the digital recorder or NVR, as well as network cables for accessing live or recorded footage. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
