Our business had an old security camera in one location that just wasn't cutting it. I was looking for a cheap alternative to expensive replacements from our national supplier. I came across this unit from a known company in the security camera business, and for the price, I figured, it's gotta be better than what we've got, I can't even tell who's on the camera now. I got this unit hooked up and the resolution's as good as the ones our security company set us up with that cost more than four times as much. The other managers are stunned as well. Everyone wants to grab one of these for their homes. It's great when you can find a quality product for a reasonable price that does exactly what it's supposed to. You just can't go wrong with this one.
