If you are using an outdoor camera you may receive false alerts at night generated by rain, snow, insects, or spider webs. This is caused by the infrared (IR) illumination of your outdoor camera, which is what gives it night vision. 


Rain and snow will reflect the IR light, causing a very obvious movement in the view of your camera. 


Many insects are attracted to IR light as much as to visible light and this makes in front of your camera a great place for spiders to build their webs. 


The most effective way to deal with this is to use infrared floodlights to provide to night vision illumination. Note you need an IR floodlight with a wavelength of 850nm.


You can set up your infrared floodlight to face the same direction as your outdoor camera and then tape, or something more permanent and aesthetically pleasing, over the LED's on the front of the cameras, leaving the light sensor untaped (see pictures below). This lets the camera switch into night vision mode automatically when it gets dark enough, but use the infrared light from the floodlight. 



We are working on a better solution than taping off the camera LED's, and will add it to this page when it is added to the CleverLoop app. 


As any snow, rain, insects or spiders will now be in front of the floodlight, rather than directly in front of your camera, this will greatly reduce your chances of receiving false alerts at night.


The other method, which works well to reduce alerts particularly from rain, is to place cameras under an eave, awning or some other cover. This means that the rain is further away from the camera lens, which does reduce the number of alerts.


Note: don't forget to select the 'facing outside' function in 'fine tune smart detection', it is designed to handle outdoor monitoring.
