CCTV surveillance cameras system is known as closed-circuit television, which is the name taken from the English term for this technology.

It refers to the surveillance system in which signals are not distributed to the public but are monitored and is used for purposes related to maintaining safety and protection for various facilities and buildings.

CCTV relies primarily on placing cameras and monitoring the camera inputs on monitors somewhere. Because cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation “closed-circuit” to indicate that access to their content is limited by design only to those able to see it.

Older CCTV systems used small, low-resolution black-and-white screens with no interactive capabilities. While modern CCTV displays can be color, high resolution, and can include the ability to zoom in on an image or track something among their features. Talk CCTV allows an overseer to speak to people within range of the camera’s associated speakers when needed.

CCTV is commonly used for a variety of purposes, including:

• Maintain perimeter security in medium- to high-security facilities.
• Monitoring the behavior of inmates and potentially dangerous patients in medical facilities.
• Monitor traffic.
• Oversee locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.
• Maintain the security of buildings and grounds.
• Obtain a visual record of activities in situations where it is necessary to maintain security or access controls, e.g., in a diamond cutting or sorting operation in banks or airports.

There is a wide variety of CCTV surveillance cameras, specially designed to suit all tastes and different security needs.

Here is a closer look at the most prominent of these types:

1. Dome CCTV Cameras

Dome CCTV cameras are relatively discreet in appearance, as it makes it difficult for people to see which direction the camera is pointing, due to its unique and purpose-built design.

This creates an air of uncertainty for potential thieves or vandals approaching from all directions.

It is the best for shops, restaurants, hotels and other hospitality businesses, because its unique design allows you to monitor a wider angle at the workplace.

2. Bullet CCTV Cameras

Bullet CCTV cameras feature an iconic design that is highly visible. They are cylindrical in shape and are capable of observing over long distances. This type of cameras is most commonly placed outdoors, so their casings are made resistant to water, dust and dirt.

On the other hand, Bullet CCTV cameras are suitable for being in various industrial and agricultural facilities. Because it sends out a message to passers-by that the building is under surveillance.

This camera can be relied upon, because it is highly visible to act as a deterrent to criminals or vandals, and it is also resistant to conditions in challenging environments, in addition to providing close surveillance over long distances.

3. C-Mount CCTV Cameras

C-Mount CCTV cameras are the ideal option for those who may wish to adapt the field of vision. They are equipped with detachable lenses that can be switched around to monitor varying distances.

Special lenses can also be fitted to the camera to extend its range beyond 40 feet. This camera is distinguished by its visible appearance that deters criminals and vandals. A rugged camera casing can also be added to protect the camera in very hot or cold environments.

On the other hand, this camera is particularly popular in the utilities and logistics industries. It is also an ideal choice for those working in the food and manufacturing industries, due to the camera’s reliability in extreme temperatures.

4. PTZ Pan Tilt & Zoom Cameras

Using the Pan Tilt & Zoom camera, you can have complete control over what is being recorded. With the touch of a button, the camera lens can be moved left and right, tilted up and down, or zoomed in and out.

It is therefore the ideal choice if you have a security guard who monitors live video on site. The optical zoom on these cameras also means that you can focus closely on various objects in the perimeter of your facility.

5. Day/Night CCTV Cameras

These cameras have been specifically built to operate very effectively regardless of how well-lit their environment is. These cameras record pictures and videos very clearly during both daytime and night-time. This is achieved through ultra-sensitive imaging chips.

As for the most prominent reasons that encourage you to use this type of camera, it is the clarity of the images in low light, in addition to its rugged casing that protects it against different climatic conditions.
