So usually, there's a transformer that cuts mains AC at 110ish volts down to 16ish volts. Then this voltage is used to power things like dumb doorbells and alarm panels.
This is mine that powers my doorbell.
You might have an alarm panel, and I think that because the device you have in the picture looks like an old motion detector, or some model I haven't seen.
You could have a transformer next to your breaker panel like this If you do, and a white/red/grey/beige square enclosure nearby
You can safely cut or unscrew the wires off the exposed side of the transformer. If you want to be super safe you can turn off that breaker before you do it, but you really just don't want to bridge the contacts that the wires on the transformer are connected to.
