• FPV drone racing and freestyle flying
• Aerial photography and videography
• Surveillance and security systems
• Hobbyist and professional drone builds

The following table outlines the key technical details of the Caddx Ratel 2 1200TVL camera:

The Caddx Ratel 2 1200TVL camera features a 4-pin connector for power, video, and control. The pinout is as follows:

1. Power Connection: Connect the VCC pin to a power source within the range of 5V to 40V. Ensure the power supply is stable to avoid damage to the camera.
2. Ground Connection: Connect the GND pin to the ground of your circuit or power source.
3. Video Output: Connect the VIDEO pin to the video input of your FPV transmitter or display device.
4. OSD Control: Use the OSD pin to connect the camera to an OSD controller or flight controller for adjusting camera settings.

• Voltage Range: Ensure the input voltage is within the specified range (5V - 40V) to prevent damage.
• Mounting: Use appropriate mounting hardware to secure the camera to your drone or project. The camera is designed for micro-sized mounts (19mm × 19mm).
• Lighting Conditions: The camera performs exceptionally well in low-light conditions, but for optimal results, avoid direct exposure to intense light sources.
• Signal System: Switch between PAL and NTSC modes as needed to match your display or FPV system.
• Lens Protection: Keep the lens clean and free from scratches to maintain image quality.

While the Caddx Ratel 2 1200TVL is primarily used in FPV systems, it can also be connected to an Arduino UNO for basic video signal processing. Below is an example of how to connect the camera to an Arduino UNO:

// Example: Reading video signal from Caddx Ratel 2 1200TVL with Arduino UNO
// Note: Arduino UNO cannot process analog video directly. This example assumes
// the use of an external video decoder module (e.g., LM1881) to extract sync signals.

const int videoSyncPin = 2; // Pin connected to the sync output of the video decoder

void setup() {
  pinMode(videoSyncPin, INPUT);
  Serial.begin(9600);
  Serial.println("Caddx Ratel 2 Video Signal Test");
}

void loop() {
  // Read the sync signal from the video decoder
  int syncSignal = digitalRead(videoSyncPin);

  // Print the sync signal state to the Serial Monitor
  Serial.print("Sync Signal: ");
  Serial.println(syncSignal);

  delay(100); // Delay for readability
}

Note: The Arduino UNO cannot directly process analog video signals. Use a video decoder module (e.g., LM1881) to extract sync signals or other data from the video output.

1. No Video Output

   • Cause: Incorrect wiring or power supply issues.
   • Solution: Verify all connections, ensure the power supply is within the specified range, and check the video cable for continuity.

2. Flickering or Distorted Video

   • Cause: Signal interference or incorrect PAL/NTSC setting.
   • Solution: Ensure proper shielding of video cables and switch to the correct signal system (PAL/NTSC).

3. Camera Overheating

   • Cause: Prolonged use in high-temperature environments.
   • Solution: Ensure adequate airflow around the camera and avoid operating in temperatures above 60°C.

4. OSD Menu Not Accessible

   • Cause: OSD pin not connected or incorrect configuration.
   • Solution: Verify the OSD pin connection and ensure the flight controller or OSD controller is configured correctly.

Q1: Can the Caddx Ratel 2 be used with digital FPV systems?
A1: No, the Caddx Ratel 2 is an analog FPV camera and is not compatible with digital FPV systems like DJI or HDZero.

Q2: How do I switch between PAL and NTSC modes?
A2: Use the OSD menu to switch between PAL and NTSC modes. Refer to the camera's user manual for detailed instructions.

Q3: What is the field of view (FOV) of the camera?
A3: The FOV depends on the lens used. The 1.66mm lens provides a 165° FOV, while the 2.1mm lens provides a 145° FOV.

Q4: Is the camera waterproof?
A4: No, the Caddx Ratel 2 is not waterproof. Avoid exposing it to water or moisture.

Q5: Can I use this camera for non-drone applications?
A5: Yes, the camera can be used for other applications such as surveillance or robotics, as long as the power and video requirements are met.
