teardown DS-2TD2138-7/QY Thermal Network Bullet Camera
« on: February 25, 2024, 03:14:08 am »
I spent 40 $ get a Thermal Network Bullet Camera. To be honest, I was shocked when I received it.
It was very heavy. The system that connects to the network is truvision.
It's not a traditional Hikon system, which is interesting. And then I took it apart.

The interior is divided into three parts
Thermal imaging module, motherboard, power board.
It's too long to hold a motherboard.

Thermal imaging movement is 12um, very low power consumption, very suitable for portable devices.

So I put together an esp32 to rs232 little thing. It can control the stop and activate the cvbs function, and power the movement.

However, I finally encountered a problem that I did not understand.
The cvbs output of the motherboard was completely normal, but there was a problem with the cvbs output of the movement, which I could not solve.


 :scared: :scared: :scared: :scared: :scared:

module cvbs output normal speed


module cvbs output 1/10 speed

 How do you control this core?  Send some command through the serial port? I'm a little curious about what the interface of this core is

rs232,control it.for example nuc


unsigned char b[7]={0xF0,0x03,0x36,0x11,0x00,0x47,0xFF};

void setup(){
  Serial.begin(19200);
  pinMode(2, INPUT_PULLUP);
 
}

void loop(){
  if (digitalRead(2) == LOW) {
    if (digitalRead(2) == LOW) {
      while (digitalRead(2) == LOW) {
      }
      Serial.write(b,7);

    }
    delay(500);

  }

}
