Embodiment 1
[0026] Embodiment 1: as Figure 1-4 Shown, a kind of video recording controller comprises signal detection module 1, delay control module 2, power supply module 3; Power supply module 3 is connected with signal detection module 1, delay control module 2 respectively; Signal detection module 1, delay When the control module 2 is connected;
[0027] The power module 3 is rectified and filtered by the commercial power through a transformer to obtain a DC +12V power supply for the probe, and can charge the battery at the same time; the +12V power supply is stabilized to obtain a +5V power supply for delay control Module 2 is used, and the battery is used for power supply to ensure the normal operation of the recorder controller during power failure;
[0028] The delay control module 2 is a monostable timer, and the trigger signal is provided by the signal detection module 1, and its output is used to control the trigger recorder;
[0029] The signal detection module 1 is compose...

The invention relates to a video recording controller, which belongs to the technical field of security prevention. The video recording controller includes a signal detection module, a delay control module and a power module. The power module is connected with the signal detection module and the delay control module. The signal detection module and the delay control module are connected with eachother. The commercial power of the power module is bucked, rectified and filtered by a transformer to obtain +12V power, and +5V power is obtained after voltage stabilization. The voltage of the +12Vpower is stabilized again to obtain +5V power which is used by the delay control module. A storage battery is used for supplying power to ensure normal operation of the recorder controller under the condition of power failure. The delay control module trigger signal is provided by the signal detection module, and is output to control the triggering of a recorder. The signal detection module is used for generating the trigger signal needed by the delay control module. The video recording controller can be used in areas equipped with monitoring probes and alarm devices, such as banks, treasuries, garages, warehouses, important departments, service windows and other occasions. The video recording controller has the advantages of simple structure, easy manufacture and strong practicability.
Description
