I want to put the camera in a remote control car

Is it just a case of connecting the camera to a suitable battery for video transmission to goggles?

Adding a camera to a remote control car for video transmission to goggles involves a few key steps and considerations:

Power Supply

The camera and video transmitter (VTX) will need a suitable power source. There are a few options:

  1. Use the RC car’s main battery: You can tap into the car’s battery to power the camera and VTX, but you’ll need to ensure proper voltage regulation. Many cameras and VTXs require 5V, while RC car batteries are often higher voltage.

  2. Separate battery: You can use a dedicated battery for the FPV system. This avoids potential interference from the car’s electronics but adds weight.

Voltage Regulation

If using the car’s main battery, you’ll likely need a voltage regulator:

  • For a 5V camera/VTX system, a linear voltage regulator like the LM7805 can work well.
  • Some hobbyists use adjustable regulators like the Anyvolt micro for more flexibility.

Camera and Transmitter Setup

  1. Choose an appropriate FPV camera and video transmitter. All-in-one units that combine both are available for simplicity. - TheFPV SA Micro AIO FPV Camera And 200mW VTX

  2. Mount the camera securely on the RC car. Double-sided foam tape can work for a quick setup.

  3. Connect the camera to the voltage regulator (if used) and then to the power source.

  4. Ensure the video transmitter is properly connected and on the same frequency as your FPV goggles.

Additional Considerations

  • Interference: The car’s electronics can cause video noise. Proper filtering or separation may be necessary.
  • Range: The built-in transmitter on all-in-one camera units often has limited range. A separate, more powerful VTX may be needed for longer distances.
  • Antenna placement: Proper antenna positioning is crucial for good video quality and range.
  • Legal restrictions: Be aware of local laws regarding video transmission frequencies and power levels.

While it’s possible to simply connect a camera and transmitter to a battery, taking these factors into account will result in a much better FPV experience with your RC car.
