Hospital surveillance video can save the minimum standard save a month time, if required to increase the hard disk, save a few months to half a year.
Hospital surveillance video can generally be kept for about 1~6 months. The current state of China's hospital surveillance video specific preservation period is not explicitly stated, with reference to the public **** place related to the regulations generally require a minimum of 30 days ~ 90 days, depending on the hospital surveillance video storage equipment and the hospital's own planning.
The controversy about the video preservation time, one is the original surveillance video preservation time, the second is in the original surveillance video preservation time after the occurrence of medical disputes copied down the video preservation time. The original surveillance video preservation time of the dispute, the most controversial in the reality of the dispute, there are said to be a day, there are said to be a week. In terms of the current technical means to save a month should be able to do.
Video Surveillance Working Principle
The control layer is the core of the whole video surveillance system, which is the clearest manifestation of the system's technological level. Usually we have two types of control - analog control and digital control. Analog control is an early control method, its console is usually composed of controllers or analog control matrix, applicable to small local video surveillance system, this control method is less costly, the failure rate is small.
But for the medium and large video surveillance system appears to be a complex operation and no price advantage, digital control is an industrial computer as the control core of the monitoring system, it will be complex analog control operation into a simple mouse click operation, the huge analog controller stack shrinks to an industrial computer, the complexity of a huge number of control cables into a serial telephone line.
