(The main solution in this case: a certain hospital has not established a video monitoring system before, and mainly relies on a set of anti-theft alarm system to carry out security protection for each important area of the hospital, but the alarm system can not realize remote real-time viewing of key prevention areas and video recording of abnormal conditions. In order to strengthen the hospital's own security level and promote the safe and orderly operation of the hospital's working environment, The service level is further improved. It is planned to build a set of digital network video monitoring system covering the relevant floors, stairs, passages, parking lots and other important parts of the whole hospital.)
