Abstract

The invention provides an infrared triggered monitoring controller. The infrared triggered monitoring controller comprises an infrared sensor PIR (Pyroelectric Infrared Sensor), a connector A, a connector B, a connector C, a sensing signal processor IC1, a video decoder IC2, a digital signal processor IC3, resistors R1 to R13, capacitors C1 to C10, a crystal oscillator Y and a power supply, wherein two pins of the IC1 are connected with pins GP4 and GP5 of the IC2 as well as a pin PND of the IC3; a pin PCLK / SCLK of the IC3 is connected with a pin VP0CLK of the IC2; a pin SCL of the IC3 is connected with a pin SCL of the IC2; a pin SDA of the IC3 is connected with a pin SDA of the IC2; a pin YOUT[6:0] of the IC3 is connected with a pin VPOD[8:2] of the IC2; a pin YOUT[7] / 12C of the IC3 is connected with a pin VPOD[9]. The infrared triggered monitoring controller provided by the invention has the advantages that when no persons make activities in a monitoring area, a monitoring system iscontrolled to automatically enter a dormant state; when persons enter the monitoring area, the monitoring system is waken up to start operating, so that electric energy, storage space and replay timeof the video monitoring system are saved to the maximum extent. The circuit has the advantages of simple structure, low power consumption and stable operation; waking for the monitoring system is sensitive, quick and reliable, so that missing of monitored objects can be avoided.

Description

technical field [0001] The invention relates to a video monitoring control device, in particular to an infrared trigger monitoring controller. Background technique [0002] With the improvement of people's awareness of safety and rights protection, public places such as schools and hospitals often install video surveillance systems to record and leave traces of people's activities. In order not to miss the monitored object, the video surveillance system in the prior art needs to operate 24 hours a day. However, at night and other times when few people come and go, if the video surveillance system operates continuously, it will not only cause a great waste of power and storage space, but also seriously occupy the playback viewing time, greatly reducing the viewing efficiency. Therefore, how to provide a control device capable of automatically starting the video monitoring system with the appearance of the monitored object has become a problem worth solving.
