Dual camera surveillance and control system

Abstract

The invention provides a dual camera monitoring and control system. The system includes a high sensitivity monochrome camera with enhanced infrared response, an array of infrared illuminators for zero ambient light monitoring, and a color camera that does not require enhancement in the infrared spectrum. The system also includes ambient light intensity perception, video signal exchange technology and energy conversion circuits. The system combines optimal monochrome imaging in low-light or no-light conditions with optimal color tinted imaging in high ambient light conditions, both for high-quality image clarity. The dual-camera feature of the system is evident to the user due to the integrated automated control of the system, which also reduces energy consumption, thus making the system suitable for wireless, remote, self-sufficient systems that operate from surrounding The environment gains energy.

Description

technical field

[0001] The present invention relates to surveillance cameras. It is important for surveillance cameras to be able to record video at night or in other low visible light conditions. At night, there is little or no visible natural light sufficient to record visible light images, and providing artificial light at night or over large distances and areas is generally undesirable or infeasible in order to be able to record visible light images. Especially if turned on suddenly in response to the perception of a break-in, the artificial light may alert a burglar when the preferred goal is to register the burglar. Continuous lighting of large areas by man-made installations is very expensive and simply impossible in remote areas. Using infrared illumination, it is possible to obtain a satisfactory image of a scene at night without alerting burglars. Background technique
