According to the customer's description, make a set of perimeter protection of 10 defense area hanging net. The whole system is required to be able to prevent the illegal invasion of the outside world 24 hours, and provide a safe and harmonious environment. It is required that once an illegal person attempts to invade, the detection unit laid on the medium can immediately sense the intrusion signal. Generate alarm signal.As shown in the figure, according to the site conditions, the perimeter length is 600m, and 10 defense areas are divided in total. One rf960 equipment is required, each defense area is about 60m. The intrusion detection host is placed on the first floor of the monitoring room. All outdoor devices do not need power. Rf960 outputs the switching value to NVR to complete video linkage. When there is an intrusion, the network management software will report the alarm of the defense area on the plant map and call the associated camera screen. The optical cable is divided into guiding optical cable and sensing optical cable. The guiding optical cable is 24 core single-mode light armored optical cable, and the sensing optical cable is 4 core single-mode light armored optical cable.

The optical cable topology is as follows:

According to the site conditions, the site is a protective mode of iron fence, and the sensing optical cable is laid in a double straight line way, which can detect climbing, climbing, ladder assisted climbing and other intrusion ways. By laying multi-channel vibration sensing optical cable horizontally, the sensing area of the fence can be increased, so as to effectively detect weak intrusion signals. This method is suitable for places with higher alert level. The vibration sensing optical cable is laid along the top of the fence, and when it reaches the end of the defense area, it is laid in the opposite direction. For field binding of optical cable, it is required to fix it with metal binding wire every 25 cm to ensure that the optical cable is fastened on the fence. The head and tail of the optical cable shall be reserved with a margin of 3-5M for later maintenance.

When a perimeter protection system has more defense areas, or there are video monitoring devices (such as cameras, DVR / NVR) in the system, it is necessary to consider how to integrate the system and other types of perimeter protection systems into a whole.Connect the rf960 switch output to DVR / NVR to realize the linkage with the camera. The linkage mentioned here can be to switch the relevant video picture of the intrusion event to the prominent position, or to drive the PTZ camera to the appropriate preset position immediately after the event to observe the event scene.

The central machine room alarm linkage topology is as follows:

Rfview software management
