Embodiment Construction

[0028] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0029] see figure 1 , as shown in the figure, an unattended alarm prompting method includes the following steps:

[0030] (1) Pre-set the monitoring range of the infrared detector and the camera, set the infrared detector as the first line of defense, set it at the entrance and exit of each channel, and set the camera as the second line of defense. Determine the monitoring status of the infrared detector and the camera in the monitoring area. If it is on, the transmitter of the infrared detector sends infrared rays, and the receiver of the infrared detector receives infrared rays. When the infrared beam is blocked, the receiving If the camera signal changes, the signal processor of the receiver processes the infrared signal into a s...

Abstract

The invention relates to an unattended alarm prompting method and a device. The method comprises the following steps: (1) infrared signals of an infrared intrusion detector receiver change, and the infrared intrusion detector sends switching value signals to a hard disk video recorder; (2) a camera outputs video signals to the hard disk video recorder; (3) the hard disk video recorder receives the switching value signals or / and the video signals change, alarm equipment is controlled to start, and alarm signals are outputted to a computer terminal; and (4) popup of an alarm point video is carried out automatically by the computer terminal and alarm information is given. According to the method and the device of the invention, through combination of video detection of the infrared intrusion detector and the hard disk video recorder, illegal intrusion is monitored by using dual-protection line, stability is high and the precision is high; and by the combined alarm of the alarm equipment and the dynamic video, illegal intrusion can be prevented timely and effectively, part of manual work can be replaced, and management cost is reduced.

Description

technical field [0001] The invention relates to an unattended alarm prompting method and device, specifically a method and device for realizing an unattended alarm through the combination of an active infrared detector and a video detection function of a hard disk video recorder. [0002] Background technique [0003] At present, enterprises and units adopt the manual guarding method of arranging security personnel for the management methods of each door post. In particular, the number of entrances and exits in and out of the factory area of ​​large and medium-sized enterprises has increased. The normal working hours of some of the entrances are open to the outside world during the day and closed at night. In consideration of the company's security responsibility, a three-shift system is generally set up. staff on duty. Because of the physiological characteristics of the human body, there is a possibility that night duty personnel are prone to fatigue and drowsiness, which ...
