From the time a wifi trail camera captures movement until it snaps the picture is called trigger speed.
With technology in place, this time has really turned out to be something between 0.3 to 1 second; however, if the camera is unable to have a faster trigger time, you are going to receive a lot of half body images or even worst, completely blank images where there are no animals or game.
Even when the main purpose of a cellular game camera is to send images wirelessly and have the user manage features remotely or from the comfort of a mobile device, having more than 5% of images without a target suggests that the device is triggering too slowly.
Some wireless game cameras may have options for users to remotely configure or change the night vision trigger speed, which could render different quality images. The result of adjusting night trigger speed could have the cam take darker images with less motion, brighter but blurred images with good motion, or a combination of both.
The following information displays the trigger speed of top brand wireless trail cameras:
