Full Form of CCTV
The CCTV full form is Closed - Circuit television cameras. The CCTV cameras introduced by Walter Bruch can obtain images or recordings for surveillance and other private purposes. Cameras can be of two types namely Video camera and Digital still camera. The main purpose of CCTV cameras is to capture light and transform it into a video signal. At the bottom of the CCTV camera is a CCD sensor (charged - couple device). The CCD transforms light into electrical signals and this electric signal into a video signal through signal processing that can be recorded or displayed on the screen.

What is a CCTV Camera?
A closed-Circuit television camera, also known as video surveillance is a system that enables you to keep an eye on what's going on in and around your business. The camera and monitor enable you to view live events, and record archive footage for future use.

The term closed-circuit in CCTV means live-streams are usually conveyed to a limited (closed) number of monitors, unlike regular television which is broadcast to the public at large. CCTV cameras are generally used to detect and deter criminal activities and record traffic violations, but these cameras have other uses also.
In June 1927, the first mechanical CCTV system was introduced by Russian Physicist Leon Theremin. Siemens AG installed another early CCTV at Test Stand VII IN 1942 for observing the launch of V-2 rockets.
CCTV Security Camera Types
All CCTV cameras aim to capture footage. These cameras are especially important when your business is located in a high crime area or has a vulnerability around your buildings which people could exploit. However, in industrial areas, CCTV equipment may be used to observe parts of a process from a central control room, for example when an environment is not conducive to humans. CCTV cameras may work continually or only as required to observe a particular event. Here are different basic types of security cameras that are commonly used.
Wired Security Cameras- These cameras use a series of cables that conducts footage and transform that footage into a monitor system. Transmission may get weak when the range is over 300 meters. However, using necessary signal boosters, switches, and network cables helps to minimize the long-range transmission issues. Multiple cameras generally interconnect to a monitor system located in the security room.
Analog Security Camera - These are the most commonly used and oldest types of CCTV security cameras. These cameras save images to a digital recorder which transforms the videos into a digital format. To view the videos that are saved, the DVR needs to be connected to a monitor or router to be broadcast through an internal network for remote access. However, there are some government regulations for the strength of analogue signals.
Internet Protocol Cameras - An internet protocol camera is a type of digital video camera that receives control data and sends image data through an IP network. These cameras are commonly used for surveillance and in comparison to analogue cameras, which require no local recording device, but only a local area network. Most internet protocol cameras are webcams, but the term IP camera generally applies to those that can be directly accessed over a network connection, generally used for surveillance. In 1966, the first centralized IP camera i.e Axis Neteye 200, was introduced by Axis.

Different Video Recorders for CCTV Security System
Video recorders are an important component of CCTV security systems. Each time, a CCTV camera captures something of interest, a recorder archives the footage and enables you to view it after certainty. The DVRs and NVRs are two basic forms of video recording options.
Digital Video Recorders (DVR)
It is an electronic device that saves videos in a digital format to a disk drive, USB flash drive, SSD memory card, SSD or other local or networked mass storage device. These digital video recorders were first launched in traditional analogue systems. DVRs can digitize videos from analogue video surveillance cameras at the desired frames per second and resolution. Hard disks are the recording media for DVRs. When the hard disk storage space gets full, the new image records over the original image, making it possible to view your videos as the incident occurs.
Network Video Recorder (NVR)
A network video recorder or NVR is a specialized video recording system that consists of software programs that record videos in a digital format to a disk drive, USB drive, SD memory records, and other mass storage devices. An NVR is typically used in IP video surveillance systems.
An Additional Note About Hard Disk
You must choose a surveillance-grade hard disk for both your NVR or DVR as surveillance-grade DVR includes more additional components in comparison to the hard drives that are used in traditional computers, which enable them to operate 24 hours if required.
Benefits of Installing of CCTV Camera in Business
Here are some of the benefits of installing CCTV camera in business:
Crime Reduction
