If you are using your Canary Flex outdoors you may receive constant recordings at night from objects such as rain, snow or insects. This is directly caused by the infrared lights from the device, which is how the Canary sees in dark environments.
When plugged in, your Canary Flex uses "computer vision" to determine if motion is happening. It's basically just looking at changes in the pixels on the screen. Any pixels changing is registered as motion. Our computer vision algorithms then try to filter out repetitive motion from things like ceiling fans, or background motion like lights and shadows. However, inevitably some motion is going to get passed those filters.
With night vision in particular, the infrared light bounces off precipitation particles falling very close to the camera or insects and it's very difficult for the Canary to distinguish this from important motion. Additionally insects are attracted to IR light just as much as to visible light from the devices LED ring.
Here are a few suggestions that may help reduce notifications from rain, snow and insects.
When used unplugged, your Canary Flex will detect motion using its passive infrared (PIR) sensor. This sensor will blast the area with rays of passive infrared, which will detect heat signatures. When something with a different heat signature than the surrounding environment passes through those rays, it "trips" the sensor and your Canary Flex begins to record. This is going to be less likely to pick up something like precipitation. When the device is on battery, if there is no motion activity the Canary Flex LED ring and single IR LED also are turned off to conserve battery which will help attract fewer insects.
Note: Currently there is no way to turn off Flex's LED light ring when plugged in.
Adjust recording range
We suggest adjusting the recording range for your Canary Flex on battery to see if you can get better motion detection at the distance that your device is mounted. This would allow you to avoid the constant recording from precipitation without compromising your motion detection for more important things.
We recommend placing the Canary Flex in a well illuminated area outdoors. You may elect to install an external light source such as flood lights or a remote IR illuminator to help attract the insects away from your Canary. A flood light would additionally allow your device to operate with enough light to stay in color mode and increase the field of view.
Remote IR illuminators such as infrared floodlights are a great way to provide additional IR light to your Canary when the environment is dark. Additionally, snow, rain and insects would be attracted to the IR floodlight rather than your cameras single IR LED. If setting up an infrared floodlight, it is recommended to place the light in the same direction that your outdoor camera faces.
