CCTV System : –
CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera’s input on monitors somewhere. Because the 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.

Types of surveillance cameras : –
Many people are now using surveillance cameras to guard their homes and facilities. These cameras capture high-resolution video in a wide range of formats, and then send it directly to connected devices, whether it is TV screens, computers or tablets. Or mobile phones, it is important that they record images and videos so that they can be consulted later in case of a security breach or any problem where the camera is located, so we rely on them heavily in the company security guards when guarding any facility we secure, whether private Or general. The mechanism of action of surveillance cameras Most surveillance cameras require to be placed in a wireless range because they usually work on Wi-Fi, in order to transfer video from the camera to the operating device of any kind, and it should be noted that the continuous update of these cameras made it possible to keep the camera on even With Wi-Fi disconnected, it gives greater protection and security so no one can stop recording it as long as it is connected to its adapter.

Types of surveillance cameras : –
The types of cameras used for surveillance vary, and although there are many variations of them, they are classified into only three types and are the following: Wireless cameras: a type of cameras is flexible in terms of installation and use, it does not contain any connections or wires, but the only problem is that it depends on the wireless Internet is very large, exposing them to the possibility of cutting the signal if the Internet is weak. Large cameras: from their name are large and visible cameras covering large areas of any ocean, so they are often used in open areas under official control. Hidden cameras: They are very small cameras can be hidden anywhere to cover the place without the knowledge of the entry, and is usually used for security reasons, as it is considered the most expensive surveillance cameras.

Because the 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 monitors with no interactive capabilities. Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera’s associated

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

• Maintaining perimeter security in medium- to high-secure areas and installations.
• Observing behavior of incarcerated inmates and potentially dangerous patients in
  medical facilities.
• Traffic monitoring.
• Overseeing locations that would be hazardous to a human, for example, highly
  radioactive or toxic industrial environments.
• Building and grounds security.
• Obtaining a visual record of activities in situations where it is necessary to maintain
  proper security or access controls (for example, in Industrial, Refinery, Bank, Airports and
  Schools).
