Video surveillance systems or commonly known as CCTV systems (Closed-circuit television) or surveillance cameras / CCTV systems today, although there are many different solutions, but they are still the same. based on the following three technologies:

 

Solutions using completely analog signals (Analog CCTV system): these are solutions that use analog technology to transmit observed images from CCTV cameras to the central control room. All devices used in this solution are analog devices.

 

Hybrid Solution: upgrade from an all-equipment solution using analog technology by digitizing the recorded image storage system. Surveillance camera equipment still uses analog signal technology, but the storage uses digital storage devices.

 

Total network – IP Solution: fully digitized from the terminals which are CCTV cameras, transmission media and storage and management systems. This is the solution that applies the latest technology today and brings the most utility value and overcomes many disadvantages of the previous solutions.
