Factor Distance Into the Equation
You need to have the right combination of lens and camera that takes into consideration the distance from the area you are trying to monitor when you want to use analytics with the camera.
“I’ve talked with customers who want to put a camera 250 yards away at the widest setting, and then they want to detect motion. It’s just not going to happen,” says White.
“The only way to detect at that distance effectively is to move over to thermal, which has a big tradeoff because the maximum resolution for thermal is VGA. Also, thermal has no color. It is not even monochrome … it almost looks like a negative. Thermal cameras can detect at a very long distance. You will certainly detect activity and you might be able to determine if it is a person or an animal.”
