Network hard disk video recorder connected to network camera installation scheme, all the answers are suitable for you!

Since you can ask here, I believe you know something about it. The wireless network monitoring system mainly consists of the following three parts.

1: Front-end image acquisition system: camera, lens and pan/tilt. Install 1 or more corresponding monitoring cameras (color or black and white, fixed or movable pan/tilt, fixed focus or zoom) at each monitoring point, collect real-time video signals of each monitoring point, and then equip the periphery with pan/tilt, protective cover and pan/tilt controller. The pan/tilt can be controlled by the computer in the control center, and the user can control the camera to be 360 degrees horizontally, 90 degrees vertically and zoom. Each video acquisition point is equipped with a video encoder to convert analog information into digital information suitable for network transmission.

2. Wireless transmission system: wireless microwave equipment. Wireless link system is the transmission channel of video information, voice information and data signals. At the same time, due to business needs, the camera, lens and pan/tilt are controlled in the control center through the console, so the transmission system also contains control signals. The signal of wireless microwave equipment will be refracted, reflected and diffracted when encountering obstacles, and some signals will be absorbed, resulting in signal attenuation or distortion. Therefore, there will be no congestion on the wireless link channel. In the case of occlusion, consider choosing a relay point, which will transmit the transmitted information to the monitoring center.

3. Monitoring management center: The monitoring center is mainly composed of video decoder, matrix TV wall, monitoring server, hard disk video recorder and video server. , can complete the reception and display of live images, video storage, retrieval, playback, backup and recovery.

For your later question, it depends on your own equipment configuration. Different configurations allow different upper limits of cameras to be accessed. Relatively speaking, the overall connection mode is relatively intuitive. Load the hard disk into the network hard disk video recorder, and the monitoring camera is directly connected to the video distributor. The video distributor directly connects the separated video signal to the network hard disk video recorder, and the other video signal is connected to the optical fiber transceiver. The function of optical fiber transceiver is only to prevent the loss of long-distance transmission signals. If the distance is not too far, this equipment is not needed, and the main control room is generally far from the terminal equipment, so this method is adopted. The video signal transmitted by optical fiber is connected to the video recorder in the main control room (if front-end monitoring is not needed, the front-end video recorder can be ignored).
