GRAND FORKS — When Grand Forks police posted a picture online Monday, Aug. 12, of a man who allegedly stole money from an apartment laundry room, they knew who he was within hours thanks to a high-resolution camera.

"We did have a lot of calls for the Facebook post that we put up," said Lt. Brett Johnson of the Grand Forks Police Department. "I think that's . . . directly related to the quality of that image."

But quality isn't the only factor when it comes to using surveillance systems effectively.

According to Grand Forks-based Stone's Security Systems Inc., considering position and lighting is key.

"We'll go out and do math, take measurements, look at light (and) darkness obstructions," said security manager Chris Walsh, who explained that each system is custom designed and that not all cameras are suited to every job.

"One of the things that really upsets me, as someone in the field, is when I go and see a newscast and there's a robbery and the camera is looking down on the top of the person's head," Walsh said. "Who decided that position? That's ridiculous."
