Rotatable camera

Technical Field

The utility model relates to a network camera field, in particular to rotatable camera.

Background

With the progress of each technology of IPC (IP CAMERA), the technology of PIR (Passive infrared detector) detection sensors is becoming mature, more and more IPC products are integrated with the function of PIR detection sensors, and the PIR detector does not emit any energy and only passively receives and detects infrared radiation from the environment. Once infrared rays of a human body are radiated, the pyroelectric device generates a sudden change electric signal through the focusing of the optical system, and an alarm is sent to prompt the IPC to enter the monitoring work, so that the IPC equipment is in an ultralow power consumption standby state. At present mainstream's two first PIR sensors, because its theory of operation and fresnel lens's structural feature, the PIR sensor is only very sensitive to the human body movement response of crosscut direction, and is not very sensitive to the human body response of radial movement, and this makes IPC with the PIR sensor need carefully consider its detection angle after the installation when reinstalling, just can obtain better control visual angle and sensitivity, and some products need use the PIR probe of a plurality of distributing types even to remedy the detection blind area.
