How To Solve The IR Waterproof Camera Image Flickering Problem?
Why IR waterproof camera will appear to flicker? As mentioned earlier, when the illumination intensity is below the threshold, the infrared light to open light. Higher than the threshold is closed. We consider the situation illumination intensity slightly below the threshold: the photosensitive element detects the lighting intensity is slightly lower than the threshold value, the control of infrared light to open after emitting infrared light-emitting —– detection to improve illumination (plus the anti-back to infrared light), and exceeds the threshold value, the control infrared lights off —- led to lower illuminance detected once again control the infrared light is turned on. This back and forth constantly, causing flashing images. This situation is the reason on principle, do not say it is normal, at least not the product quality problems.
The photosensitive element detects the environmental illuminance is slightly below the threshold condition problems , there are two cases
One . Some point in the evening , when , for a short time , the emergence of this issue , if you do not gain back the cost of using the general heart piece , our idea is that users with clear reason to tolerate it .
Two . This problem occurs when the illumination intensity stability , must be addressed .
1 . Changing the threshold .
Same model , the threshold is not the same , there are discrete . Replacement of a product may be the problem is solved .
Provide design thresholds of different products by the manufacturers , to be replaced.
A higher threshold of the product design parameters , at least some of the possibilities appears to flicker.
2 . Changes in the environment
Changing the intensity of the illumination angle .
A slight change in the angle of IR waterproof cameras installed , move it up and down , the detector detects the illumination will have a lot of change , will leave the vicinity of the threshold , so as to solve the flicker problem .
(3) the use of high quality anti-glare illumination with a camera BLC heart piece , especially dedicated IR camera ;
In addition, IR waterproof cameras or other objects near it was the reflection of infrared light , can cause changes in illumination repeatedly detected , causing flicker. For example, doing the demonstration test , testing , the lower the camera installation position , when there are objects close to the camera cover .
This is not a problem , IR waterproof cameras installed in the normal position , this is of course no. When such presentation, as long as careful not to let infrared light back directly from the close proximity to the photosensitive member wants.
