Got a wired 2k doorbell in December. With auto night vision off the IR lights (straight line) still come on at dark. The IR filter does not engage. If I turn on auto night vision the lights come on and the filter does engage. I can get the lights to go off for a while if I turn night vision on then off but they soon come back on. I don’t need night vision on and don’t want the lights on. Tried resetting the doorbell but no change. Have a new 24volt transformer. Any ideas?
