Trigger Time is a Important Feature When Buy a Trail Camera
The trigger time refers to the time in between when your hunting trail camera picks up the motion and heat necessary for triggering the shot and when the photo is actually snapped. The speed on high-end cameras usually is just a fraction of one second. You should try to find a trail camera that has a fast trigger speed since that can mean the difference between just missing the animal and capturing it in the shot.
Look for trail cameras with trigger speeds of under one second. Otherwise, the animal will most likely be out of range by the time your camera is triggered. Currently, the fastest speed available is 0.4 seconds WG-890 series. Slow models might have trigger speeds up to several seconds.
The only times a slow trigger speed might work for you is if you are going to be using your camera for monitoring a game feeder or food plot. In those situations, the animals are going to moving slowly around the area, so it won’t be all that necessary to have a fast trigger speed.
When trigger speed is a requirement, I suggest you look at the Wildguarder hunting camera or ltl acorn hunting camera. It has a 0.4-1 seconds trigger speed. What makes it more impressive is the recovery speed that is less than a second. Imagine a trail camera that takes 2 images while others are still recovering.
