[0065] Advantages: This design enhances the volume and propagation distance of the alarm and improves the security effect. At the same time, the fixed installation of the buzzer 10 ensures its stability and reduces malfunctions caused by vibration or movement.

[0066] Connection between human body detection sensitive element 13 and digital intelligent control circuit 8:

[0067] Working principle: The human body detection sensitive element 13 is electrically connected to the digital intelligent control circuit 8. When the human body detection sensitive element 13 detects human body movement, it will output a corresponding signal to the digital intelligent control circuit 8.

By controlling the level state of this port, the output signal of the alarm can be accurately controlled. The voltage divider resistor is used to adjust the voltage distribution in the circuit to ensure the normal operation of each component.

[0080] Advantages: The design of the OEN enable terminal enhances the controllability of the alarm output signal and improves the flexibility of the system. The setting of the voltage divider resistor ensures the stability and safety of the circuit.

[0087] The mounting bracket 3 is rotatably connected to the base 1 and is designed as a U-shaped bracket, so that the security alarm monitoring device 4 can rotate in the horizontal direction.

[0088] The base 1 and the mounting bracket 3 are provided with a rotator 2 and a rotator 3. By driving the rotator 2 and the rotator 3, the mounting bracket 3 and the security alarm monitoring device 4 can be rotated in the vertical direction, thereby realizing monitoring in different directions and angles.

[0089] Security alarm monitoring:

[0090] The outer wall of the security alarm monitoring device 4 is provided with a sound amplification port 5 for amplifying the alarm sound. The protective cover provided on the sound amplification port 5 not only protects the sound amplification port 5 from external damage, but also ensures that the propagation of the sound is not hindered.

[0091] The human body detection sensitive element 13 on one side of the sound expansion port 5 is responsible for monitoring the movement of the human body, and once an abnormality is detected, an alarm will be triggered immediately.

[0092] The other end of the security alarm monitoring device 4 is equipped with a camera device, including a plurality of multi-position cameras 6 and an infrared sensor.

[0094] The rotator 1 12 , the rotator 2 and the rotator 3 in the present invention can be conventional servo motors.

[0095] Signal processing and control:

[0096] The security alarm monitoring device 4 is internally provided with a signal processor 9 and a digital intelligent control circuit 8. The signal processor 9 is responsible for receiving and processing signals from the camera and the human body detection sensitive element 13.

[0097] The digital intelligent control circuit 8 is the core of the whole system, and it determines whether to trigger an alarm according to the output of the signal processor 9. When the human body detection sensitive element 13 detects an abnormality, it will send a signal to the digital intelligent control circuit 8.

[0098] The digital intelligent control circuit 8 and the human body detection sensitive element 13 are both integrated in the pyroelectric infrared sensor in the electromagnetic shielding cover.

[0099] The controller of the digital intelligent control circuit 8 adopts a single chip microcomputer, which has strong processing capability and stability. The PIR signal output by the human body detection sensitive element 13 is coupled to the digital intelligent control circuit 8 through a very high impedance differential input circuit to ensure accurate transmission of the signal.

[0100] The digital intelligent control circuit 8 also includes an OEN enable terminal for controlling the output of the REL level signal, thereby controlling the switch of the buzzer 10 .

[0101] The voltage divider resistor is used to adjust the voltage distribution in the circuit to ensure the normal operation of each component.

[0102] Light sensor 11 and energy-saving lamp 7:

[0103] The anti-alarm monitoring device is also equipped with a light sensor 11 and an energy-saving lamp 7. The light sensor 11 is used to collect the brightness value of outdoor natural light in real time. When the light is insufficient, the digital intelligent control circuit 8 will activate the energy-saving lamp 7 to supplement the light source to ensure that the camera can still work normally at night or in a weak light environment.
