Avoiding continuous day/night switching when using IR ...

When the IRC filter is removed, the sensor is also sensitive for IR light, so IR light can be used to illuminate the scene. When the gain goes as low as the camera will go back to day mode. The IRC filter is moved back in place, and the camera will switch back to color images. The following issue can occur when using strong IR illumination. When the camera goes to night mode, suddenly the ...

2013-02-28· Sunlight produces plenty of IR. For any IR detector to work in the presence of sunlight, you have to chop the IR sender at a kHz rate, use a high-gain ac-coupled amplifier at the IR detector, followed by a synchronous ac demodulator to detect the chopping frequency, which is what the TSOP type of IR receiver does. A DC coupled system is doomed...

PIR Sensor behavior with ambient lighting changes ...

2016-12-03· The product guide cautions against exposure to direct sunlight. The sun is, of course, a huge source of IR energy, which can make it more difficult to discern small changes in IR energy from a person moving. In more general terms, some PIRs have a photocell that inhibits the output when ambient light is above a certain threshold.
