In the last year, in addition to being used for video analysis and recognition of surveillance targets, Intelligent Analysis IVS also provides camera status detection and rewards in many cameras, including lens clipping, video blur or focus variation, and Picture survival status recognition function such as video loss. Such intelligent device monitoring methods generally exist in IP network surveillance cameras or IP video servers. Of course, it will also appear on some HD-SDI or 960H analog cameras. Due to the convenience of digital video entrainment, this type of method has gradually become an application trend of remote monitoring of devices. Even though IVS is the largest remote camera status monitoring method in IP network monitoring, its network bandwidth limitation and the risk of transmission traffic are the main reasons why it cannot be a reliable and stable device control application. If it is only for the fault or human damage analysis of the video part, it is still an ideal application outside the monitoring of equipment survival.

These methods are mainly applied to the monitoring of the survival status of remote cameras in engineering. Maybe you will think: Is there only a camera for remote devices? This answer is of course not only for the monitoring needs of the camera, but only for monitoring. The camera in the project is the eye of a monitoring system, the source of the main visual judgment, so the focus will first be placed here.
In the monitoring system, in addition to the camera, the remote monitoring also includes the front-end video server (DVS) or video recorder DVR, NVR or storage device RAID, NAS and other devices. The working state of these devices is not as simple as the camera. In addition to the signal and transmission, the working bias voltage of the circuit Vcc, the working state and temperature of the device CPU, and the program steps of the action are all remote device monitoring in the monitoring system. The necessary system management work, which has gone beyond the scope of equipment monitoring. In terms of the management of a monitoring system, in addition to the state control of the equipment, how to achieve remote system maintenance and system health status supervision is the above monitoring equipment. Further monitoring of remote monitoring is required in the monitoring of the equipment.
