[0003] However, when the existing monitoring device is in use, it is usually installed in a fixed position on the bidding site, so that the monitoring device has some blind spots, thus reducing the monitoring effect of the monitoring device, and although the internal A cooling fan is installed, and the inside of the surveillance camera is cooled by the fan, but the cooling fan needs to lose power when cooling down, thus reducing the energy saving of the surveillance camera. SUMMARY OF THE INVENTION
[0004] In view...
