The present invention provides an improved infrared closed-circuit television camera (CCTV) camera installed with rechargeable batteries on a rotary stand. When power supply is normal, electrical power is stored into the rechargeable batteries, which supply power to the CCTV camera, in case of power failure or damages to the power system due to fire outbreak. In this way, the CCTV camera can transmit monitored images to the monitoring center. Moreover, in case of fire or power failure, the rechargeable batteries supply power to the LED lighting sets, which automatically glitter for emergency escape illumination. Furthermore, when night illumination is less than 5 Lux during normal power supply, the LED lighting sets automatically glitter for night illumination.
