The closed circuit of television (CCTV) allows the user to see the all incidents in the supervised space. The CCTV cannot prevent a crime from taking place, but it can deter somebody from committing one. Moreover the video that has been recorded it can constitute an exceptional source for the police investigating theincident.
· Basic operations of the recording system (DVR)
· The DVRs combine digital recording of video and sound, multiplexing and input/output for interconnection with an alarm system.
· Simultaneous recording and playback.
· Remote monitoring via an application that allows access in the DVR from anywhere in the world via Internet (requires connection via xDSL in the controlled area or alternative use of 3G /4G router).
· Detection of movement for the evasion of continuous recording. If no movement is detected from a camera there is no need to record video images. In this way the same hard disk allows longer time video recording and keeps them for higher periods before erasing them with newer events. Possibility is copy video footage to external medium (e.g. USB stick).
