I installed a customer supplied ring door bell I cut a hole inside the home and fished my new doorbell wire from outside to inside then I came out of a existing receptacle to the hole I cut. Installed a old work box then installed a receptacle. I then installed a plug in transformer rated for the ring doorbells I removed and replaced a motion light on the side of the home with a company supplied high powered LED motion light and siliconed around the light for better protection Customer was shown the placement of the lights and understands if we are called to return to adjust the bulbs in the ,option light it is a separate charge Customer has a 1 year warranty
