1、 System control function inspection
a. Editing function inspection: manual or automatic programming can be realized by controlling the device keyboard to achieve fixed or sequential display and switching of all video images on the designated display.
b. Remote control function inspection: the control equipment shall control all front controlled parts such as PTZ, lens and protective cover stably and accurately.
2、 Monitoring function inspection
a. The monitoring area shall meet the design requirements. The illuminance in the monitoring area shall meet the design requirements. If not, check whether there is an auxiliary light source.
b. For key parts that must be monitored in the design, check whether real-time monitoring is realized and there is no blind area.
3、 Display function inspection
a. The images displayed in single or multiple images shall be clear and stable;
b. The monitoring screen shall display the date, time and front end of the monitored screen video camera No. or address code of;
c. It shall have the functions of picture freeze, switching display, multi-channel alarm display, arbitrary setting of video alert area, etc;
d. The image display quality shall meet the design requirements, and the image quality shall be scored at level 5 according to the current national standard Technical Code for Civil Closed Circuit Surveillance Television System Engineering (GB 50198).
4、 Record function inspection
a. The images taken by the front-end camera shall be recorded according to the design requirements, and the images required to be recorded in the design shall be continuous and stable;
b. Record date, time and the number or address code of the front camera of the monitored image shall be displayed on the record screen;
c. It shall have storage function. In case of power failure or shutdown, all programming settings, camera number, time, address, etc. can be stored. Once power supply is restored, the system shall automatically enter into normal working state.
5、 Playback function inspection
