How does the Video Doorbell Temperature Collar work?
The Video Doorbell Temperature Collar (ADC-VDBA-TC) is a molded polymer that matches the shape of the area between the ADC-VDB770 back plate and the mounting surface (whether a mounting bracket is used or not).
The temperature collar is designed to be used in very cold environments (i.e., below -30C) to extend the operational range of the ADC-VDB770. The ADC-VDB770 is designed to work with full functionality in environments as low as -30C ambient without the collar but -40C ambient with the collar properly installed. The temperature collar blocks airflow to the heat sink so that the device more efficiently retains the heat generated from internal components.
Installation
- Separate the collar at the bottom.
- Place the collar around the back of the backplate of an already mounted ADC-VDB770.
- Push the collar firmly against the mounting surface and/or mounting bracket so that the fins on the backplate are no longer visible.
- Reattach the two ends of the collar by pulling them together.
