After the wall lamps of chain hotels are turned off for 7 days, blue light will blink regularly. Is it a camera?

According to the information you provided, this situation is probably not a camera. The reasons why the wall lights of chain hotels will regularly flash blue light after being turned off for 7 days may be the blue light emitted by the TV receiver, the indicator light on the switch and the indicator light on the air conditioner.

However, in order to ensure your privacy and safety, it is recommended that you carefully check the hotel room to determine whether there are any unauthorized camera equipment. You can troubleshoot in the following ways:

1. Conduct a comprehensive search of the room, including furniture, electrical appliances, decorations and other places where cameras may be hidden.

2. Check the sockets, TV interfaces, smoke alarms and other places in the room where cameras may be hidden.

3. Use professional detection equipment, such as camera detector or ultraviolet flashlight, to detect possible cameras.

If you find any suspicious equipment, please report it to the hotel management immediately and contact the local law enforcement agencies for help.
