Baby monitor

So. Many. Options. I feel overwhelmed every time I try to look. We don’t need anything crazy high-tech and honestly the simpler the better. Camera is preferred, wireless or not does not matter, definitely one that does NOT connect to wifi/internet at all, and has decent range (ex. I can see baby in his crib while I’m in the kitchen). Are there any out there that could maybe clip onto the side of a crib as well as stand on its own? I see a lot that are wall mount or stand-alone. I think I’ve only found one that can clip onto a crib rail.
