The invention discloses a wireless remote alarm device based on a video event detector, comprising an alarm lower shell, an alarm upper shell, an assembly connection mechanism, a protection mechanism, a moisture-proof mechanism and a fixing mechanism, the alarm lower shell and An assembly connection mechanism is arranged between the upper shells of the alarm, and a protection mechanism is arranged inside the lower shell of the alarm and the upper shell of the alarm, and a chip board is installed on the protection mechanism, and the alarm The bottom center of the lower shell of the alarm is provided with a moisture-proof mechanism, and the lower shell of the alarm is provided with a fixing mechanism. Through the corresponding connection of the connecting column and the connecting groove, the lower shell of the alarm and the upper shell of the alarm When assembling, the angles of the upper protective frame and the lower protective frame set inside the two correspond to each other, and the lower casing of the alarm and the upper casing of the alarm are assembled together through the snap ring and the groove connection. It can be disassembled at the same time.
Description
technical field [0001] The invention belongs to the technical field of video event detectors, in particular to a wireless remote alarm device based on video event detectors. Background technique [0002] The video event detector can analyze the video images sent back by multiple cameras at the same time. Once traffic accidents such as car accidents, retrograde traffic, pedestrians, or congestion appear on the screen, it will automatically alarm and remind the monitoring personnel to deal with it, which greatly reduces the workload of the staff and improves the work efficiency. efficiency. [0003] The wireless alarm is an alarm that detects electrical signals transmitted by space electromagnetic waves. In some cases where the prevention site is scattered or it is inconvenient to lay transmission lines, in order to achieve wireless transmission, it is necessary to increase the wireless channel between the detector and the alarm controller. device and receiver. [0004] Ther...
