Because the dash cam body has its own built-in battery. Even after the car is parked and turned off, the dash cam still shows power because it has rechargeable and remote network control capabilities. The dash cam digitally records and cyclically updates the road conditions in front of, inside, and around the car. The recorded data includes in-car audio, the car's acceleration, steering, and braking, among other things, to be used for investigating traffic accident liability. Here is some related information about dash cams: 1. Generally, dash cams rely on the car's power to operate during the day. When the car is turned off, the dash cam stops working. Although the dash cam body has its own battery, some batteries can last for four to five hours on standby, while others may only last for about half an hour. Therefore, the dash cam can operate continuously during the day, but it will shut down at night due to power limitations. 2. Under normal circumstances, the Mondeo dash cam's power cord is connected to the ignition switch line. When the ignition switch is turned off, the dash cam also stops working. After installing a dash cam, it can record the entire driving process's video and audio, providing evidence for traffic accidents.

The continuous power supply of the Mondeo's dashcam may be due to its connection to the car's constant power circuit, such as directly to the battery or OBD port, which provide permanent power. The advantage of this design is that it starts working immediately upon ignition and continues to operate after parking, providing monitoring functions like collision detection or suspicious activity monitoring. However, the downside is that if the car isn't driven frequently, the battery may gradually drain, leading to starting difficulties or even shortened battery life. I've encountered similar situations, and the solution is to check the dashcam's wiring to ensure it's not accidentally connected to a constant live wire, or to set the dashcam to a low-power mode to reduce consumption. Additionally, some dashcam models may fail to auto-sleep due to software errors, requiring firmware updates or manual setting adjustments. If the issue persists, it's best to take the car to a professional shop for circuit diagnostics to avoid DIY modifications causing other problems. Overall, this is a common feature in Ford models, balancing convenience and safety.

When driving the Mondeo, I also noticed the dashcam keeps running. This is usually a factory setting issue where it's connected to a non-switched power source, allowing continuous recording after parking for anti-theft purposes. However, this puts significant strain on the battery, especially during prolonged parking which may lead to battery drain. I recommend regularly driving to recharge the battery or installing a battery maintainer. Check if parking mode is enabled in the dashcam settings - if there's an option, turn it off. If that doesn't work, consider switching the power source to the cigarette lighter or ACC line, which will cut power when the car is off. Additionally, an aging battery may cause the system to misjudge and maintain power supply - replacing the battery can alleviate this. Don't worry too much, most cases are caused by design.

Having worked on many cars, this issue with the Mondeo isn't new. It's likely that the dashcam wiring was incorrectly connected to a constant power source instead of being controlled by the ignition switch. First, check the fuse box or OBD port using a multimeter to see if the voltage changes with the car's ignition. If it's constantly powered, simply adjust the wiring to the cigarette lighter circuit. Also, rule out any faults with the dashcam itself, such as an internal short circuit or software glitch preventing it from entering sleep mode—try restarting or resetting to factory settings. Additionally, check the car battery voltage; if it's below 12 volts, the system might compensate by continuously supplying power. It's recommended to consult a professional to optimize the setup, avoiding energy waste while maintaining driving convenience.
