Does the heating company leak privacy by installing a temperature collector for free

1. No. The temperature collector installed by the thermal company will not be equipped with a camera. The main function of the temperature collector is to display data such as temperature, humidity and time, and does not have camera, storage and other functions. The temperature collectors provided by Thermal Power Company are distributed and installed free of charge, and users do not need to pay additional fees.

2. No.This equipment is mainly used to monitor the temperature and humidity in the room and provide the corresponding data to the thermal company in order to better control the operation of the heating system. There is no camera or storage function, only basic temperature and humidity data and time information are provided. Users can rest assured to use these devices, which will not interfere with users' privacy.

3. Free installation of thermometers is not a scammer. What involves free installation is only to provide free installation of equipment. This is generally to earn money for after-sales parts replacement, or just to open up the market. It is recommended to communicate well to avoid unnecessary trouble during installation.
