Check the battery strength inside the control box using a multi-meter. Make sure it is 11.50 volts or higher, if it is lower, recharge the battery. Recheck the connections inside the control box and that none of the connection have loosened or corroded. Check the batteries inside the onsite remote, press and hold the button for 2-3 seconds and watch for the light to come on. If the light doesn’t come on, check the battery or replace it. Re-sync the onsite remote and camera to the control box.
