Below is a guide to understanding why this happens and how to cool things down. Why Does the ZXDZ 01 Get Hot?
The camera needs two connections to function properly:
The most common installation mistake is connecting the camera’s red power wire to a constant accessory power source (ACC) rather than the reverse light circuit. This keeps the camera active 100% of the time your car is running, leading to rapid thermal buildup and shortened component lifespans. 2. Lack of a Voltage Step-Down Regulator zxdz 01 reverse camera hot
If your car uses a CANbus system (common in newer VW, BMW, Audi models), direct power from the reverse light can be "dirty" or fluctuating, causing the camera to work harder and heat up. Installing a ensures the camera receives steady, clean power directly from the battery while still being triggered by the reverse light. 3. Check for Improper Wiring
Many budget backup camera microprocessors operate internally on 3.3V or 5V. If the integrated step-down module in the wiring harness fails or lacks quality components, raw 12V–14.4V voltage from the vehicle alternator forces the camera body to dissipate excess energy as heat. 3.

, it stays powered as long as the car is on. These small cameras are designed for intermittent use (only while reversing) and will overheat if left on for entire drives. Internal Short or Defective Unit:
Warm is normal. Hot is not.
This issue is so common that it's almost become a rite of passage for ZXDZ 01 owners. One user described this exact scenario:
