Remove your existing videophone and check whether it's a 2-wire or 4-wire model before purchasing! 2. If your existing doorbell is large, remove it and see if you need a finish plate! 3.

A: When disassembling the existing device, color-coding the wires connected to terminals 1-4 with tape or something similar will help you match the order of the new product's terminals and avoid mistakes. Q: What should I do if the new doorbell camera is not securely attached because the hole is smaller than the existing one? A: First, install a commercially available "doorbell stop plate" on the wall, then secure the new camera on top of it. This will neatly cover the existing large hole and provide a secure installation. Q: Is connecting the power cord dangerous, such as from electric shock? A: Before starting work, be sure to locate and disconnect the power cord and take precautions to prevent electrical current from flowing through it. For your safety, be sure to avoid touching any two power cords.
