CCTV (closed-circuit television) is a type of TV system used primarily for security and surveillance, in which signals are monitored but not broadcast to the public.
CCTV relies on strategically placed cameras and viewing camera input on remote displays. Closed-circuit refers to the private coaxial cable lines or wireless communication links that the cameras use to link to monitors and/or video recorders, indicating that access to their material is meant to be limited to those who can see it.
Here are some benefits of CCTV:
- Peace of mind
- Deterrent and crime prevention
- Remote monitoring
- Ideal in conjunction with intruder alarms
- Reduced insurance premium
- Low price, high quality
- Prosecution.
