There are basically two types of flash options available on wireless trail cameras, IR and Black Flash, and generally a third option for regular trail cams: regular Flash.
Hunters usually get started with a regular Flash device. It takes color photos day and night and provides the highest quality possible of colored photos and almost no motion blur by day or by night.
IR cams are equipped with a set of infrared LEDs. These images are usually monochrome since the internal sensor in the device does not distinguish different frequency spectrum of infrared radiation.
These wireless game cameras have no visible lights from the side unless you are looking straight into the IR LEDs, where a very low red glow can be seeing. This warm red glow doesn’t bother the animals at all, however they´ll usually stare at it.If you are trying to compete with other hunters or planning to carry out surveillance in your property, this is certainly not the best option.
It is ideal for locations where animals are further away and less predictable, like on a filed edge or an area with numerous trails, since it provides the longest illumination range and minimal motion blur.
The IR has the ability to capture amazing night images and videos. Night images are black and white and day images are colored.
Infrared flash distance at night pictures is crucial. Most good cams should still take good night images at 60ft to 80ft distance.
Black Flash means no visible infrared flash for animals or humans to see, however, it renders less illumination performance than IRs. There are referred to as no glow or blackout infrared on the market.
It is ideal for installing right on scrapes or rubs because there is no glow, which helps the subject to be quieter when it is right in front of the camera or just a couple feet away. Therefore, you should get more photos and videos, of predators such as coyotes, bobcats, wolves because there is nothing for them to pick up on or see.
It is perfect for surveillance purposes around your property or to capture images in high traffic location or public places. Night images are black and white, day images are colored.
