cctv camera

It is now more crucial than ever to take care of your surroundings, whether they are your house, place of business or both. CCTV cameras are widely used for surveillance and security purposes. In the US, at least one security camera is present in one-fifth of all homes. These cameras consist of several components that work together to capture and transmit video footage. This blog will explore the features and workings of a high-quality CCTV camera, providing a deeper understanding of its components.

Components and Workings of CCTV Cameras

Let’s take a look at the mandatory components of security cameras and what they do:

1.   Lens

A camera’s view of the world is through its lens. It is a component that takes pictures and transmits them to the video recording device.

There are two lens types for CCTV cameras: Monofocal and varifocal lenses.

A mono-focal lens is a fixed lens whose settings are fixed and cannot be altered. Varifocal, on the other hand, allows the users to adjust the camera’s settings, like level of zoom, focal length, angle view, etc.

2.   Monitoring Station

The monitor serves one of the most integral functions of a camera as it is responsible for displaying the recorded footage.

The monitoring station allows the viewer to see what is happening in the camera’s field of view. It comes in handy when someone has to look for suspicious activity in a building or parking lot.

3.   Visor

Made up of acrylic or plastic material, the visor serves as a shield and keeps the camera safe from sun rays. It minimizes reflection and prevents unnecessary light from interfering with the camera’s ability to capture an image.

4.   Infrared LEDs

Infrared LEDs are designed to provide night vision capability to the video surveillance camera. They tend to activate automatically when its night or the lighting is dim, allowing the camera to capture even in dark situations.

Infrared can also pass through dust, fog, and dense smoke.

5.   Housing

The housing is the protective outer casing of the camera that shields it from potential damage like rain, dust as well as vandalism and tampering.

CCTV camera housing comes in different sizes, materials, and shapes, and you can get them according to your requirements.

Outdoor cameras have coverings that are stern and weather-resistant. In contrast, indoor cameras have unobtrusive, considerably smaller housings.

6.   Power Supply

It is common to connect the camera to a power source through a power cable. A power supply provides electrical power to the camera so it can operate.

It is crucial to select a power supply that provides the appropriate voltage and amperage to ensure the camera functions correctly.
