technical field

The utility model relates to a video camera, in particular to a video camera with a wireless remote control setting menu.

technical background

In low-illumination or even zero-illumination environments, ordinary cameras cannot acquire images or the image quality is extremely poor, while infrared light cameras can use their built-in infrared lights to emit infrared rays, thereby acquiring images in poor ambient illumination conditions. Because the performance of the infrared light camera meets the needs of closed-circuit monitoring at night and in low-light environments, its application is becoming more and more extensive. However, there are also certain defects in the infrared light cameras on the market. First, the technical parameters of most infrared light cameras have been set at the factory, and most cameras cannot be adjusted according to needs after being installed at a high place, which may affect the image quality. Second, most infrared light cameras do not have the functions of anti-disassembly and anti-vandalism. Once damage is caused, it cannot be found and reacted in time. Third, the brightness of the infrared light of most infrared light cameras cannot be adjusted. After installation, the brightness of the infrared light may be too strong and may be reversed. Due to these defects above, to a certain extent, installation and construction have been caused troubles, hindering the further popularization of infrared light cameras.

Detailed ways

As shown in Figures 1 and 2, this embodiment includes a body 2, a lens 4, and an infrared lamp 3. The body is also equipped with a wireless remote control system, an anti-disassembly and damage circuit, an anti-blocking circuit, an anti-damage alarm circuit, and an overvoltage alarm circuit. High and low protection circuit, infrared light brightness adjustment circuit. Thereby, the present embodiment has functions such as wireless remote control operation, anti-disassembly, anti-blocking, anti-sabotage, automatic alarm, over-high and under-voltage protection, and infrared light brightness adjustment. The above functions are respectively realized through the following technical solutions:

1. Wireless remote control operation function

As shown in Figure 2, the data pin of the wireless receiving module is connected to the IO3 port of the MCU chip, and the chip will always read the data from this port. If the reed switch connected to IO4 is triggered, it means that learning coding is to be performed. At this time, the chip will save the address code in the data read by IO3 port. If the reed switch is not triggered, it means that it is under normal conditions. The chip will compare the address code in the read data with the original saved address code according to the rolling code algorithm. If it matches, it will respond to its operation, and then restart Execute this operation according to the data code part of the read data. The execution process is to output to the control chip of the menu through BCD code or serial port. The output commands are respectively: move up, move down, confirm, and return. The menu control chip then operates the menu displayed on the display according to the instruction and simultaneously performs synchronous control. The remote control of the remote control menu: use the wireless transmitter of the rolling code, through which the menu can be controlled to move up, down, confirm and return.

2. Anti-disassembly function

As shown in Figure 2, the anti-disassembly circuit includes a mercury switch and a signal detection feedback circuit. The mercury switch is connected to the IO2 port of the chip in the detection feedback circuit. When the state of the mercury switch changes, the anti-tear alarm is started. When the camera is illegally disassembled, it will immediately send out an alarm sound to warn the illegal personnel, and can send out an alarm signal.

3. Anti-vandalism function

As shown in Figure 2, when the camera is damaged, it will immediately send out an alarm sound, and at the same time, an alarm signal is directly transmitted to the monitoring center, and the alarm information will pop up quickly in the monitoring image of the camera in text form.

4. Access occlusion function

As shown in Figure 2, the camera has a certain number of infrared lights that actively emit infrared rays. The infrared receiving tube is connected to the AD2 port of the chip, and the AD is started to judge the level change of the port. When there is a blockage, the infrared rays emitted by the infrared lights are blocked Block the reflection back, the level of the AD2 port will change after the infrared receiving tube receives it, and the chip will judge whether it is blocked according to the set value, and if it is, it will start an alarm. When the camera is blocked, an alarm sound will be issued immediately, and at the same time, an alarm signal will be transmitted directly to the monitoring center.

5. Infrared light brightness adjustable function

As shown in Figure 2, for an infrared camera with a wireless remote control setting menu, the brightness of its infrared light can be adjusted according to the site conditions. The camera is equipped with an automatic adjustment circuit for the brightness of the infrared light.
