Do Dashcams Work When The Car Is Off? (Parking Mode Guide)

Yes, dashcams can work when the car is off. This functionality is known as “parking mode” and allows your dashcam to record even when your engine isn’t running, providing dashcam surveillance while parked. However, it requires a specific setup and understanding of the technology involved. Let’s explore how dashcams achieve this and the considerations to keep in mind.

What is Parking Mode on a Dashcam?

Parking mode is a feature that enables your dashcam to continue recording even after you’ve turned off your car. It’s designed to capture incidents like hit-and-runs, vandalism, or theft attempts that occur while your vehicle is unattended. This gives you potential evidence for insurance claims or legal proceedings.

How Does Parking Mode Operate?

Parking mode typically functions in one of two primary ways:

• Motion Detection: The dashcam monitors the area in front of the lens. If it detects movement, it automatically starts recording.
• Impact Detection: Using a built-in G-sensor, the dashcam detects sudden impacts or vibrations, triggering recording.

Some advanced dashcams offer a combination of both, activating recording based on either motion or impact. Some might even offer a low bitrate continuous recording to ensure something is captured.

The Power Source Dilemma: How to Power a Dashcam When the Car is Off

The biggest hurdle in using parking mode is providing power to the dashcam when the car’s engine isn’t running. There are a few solutions:

1. Internal Battery: Some dashcams have small internal batteries. However, these typically only provide a few minutes of power, making them unsuitable for extended parking surveillance. They are primarily designed for gracefully shutting down the device after power loss.

2. External Battery Pack: A dedicated external battery pack is a more robust solution. These packs are designed to provide extended power to the dashcam, allowing it to record for hours or even days while parked. They are charged while the car is running.

3. Hardwiring: The most common and reliable method is to hardwire dashcam for parking mode directly to your car’s battery. This involves connecting the dashcam to the car’s fuse box, providing a constant power source.

The Benefits of Hardwiring

Hardwiring offers several advantages:

• Continuous Power: Ensures the dashcam has a consistent power supply for uninterrupted parking mode operation.
• Clean Installation: Conceals the wiring, resulting in a neater and more professional installation.
• Automatic Activation: The dashcam automatically switches to parking mode when the engine is turned off and resumes normal recording when you start driving.

The Danger of Dashcam Battery Drain

A major concern with running a dashcam while parked is the risk of dashcam battery drain. Draining your car’s battery can leave you stranded and require a jump start.

Low Voltage Cutoff: Protecting Your Car’s Battery

To prevent battery drain, most hardwiring kits include a dashcam low voltage cutoff feature. This crucial function monitors the car’s battery voltage. When the voltage drops below a pre-set threshold, the cutoff automatically cuts off power to the dashcam, preventing further drain and ensuring you can still start your car.

• Adjustable Settings: Many low voltage cutoff devices allow you to adjust the voltage threshold. This allows you to customize the setting based on your car’s battery type and your desired level of protection.
• Timer Settings: Some also include a timer, allowing you to set a maximum recording time even if the voltage hasn’t dropped.

Dashcam Recording When Car Is Off: Motion Detection vs. Impact Detection

As mentioned earlier, parking mode relies on either motion detection, impact detection, or a combination of both. Let’s delve deeper into each:

Motion Detection

• How It Works: The dashcam uses its camera sensor to detect changes in the scene. When it detects movement, such as a person walking by or a car approaching, it starts recording.
• Pros: Can capture a wider range of events, including people loitering near your car.
• Cons: Can be triggered by insignificant events like leaves blowing in the wind or shadows moving, leading to unnecessary recordings and increased battery consumption.

Impact Detection

• How It Works: The dashcam uses its G-sensor to detect sudden impacts or vibrations. If someone bumps into your car or attempts to break in, the G-sensor triggers recording.
• Pros: Less likely to be triggered by false alarms compared to motion detection. Only records when a significant event occurs.
• Cons: May miss events that don’t involve a direct impact, such as someone keying your car.

Choosing the Right Mode

The best mode for you depends on your specific needs and environment. If you park in a high-traffic area with lots of pedestrian activity, impact detection might be a better choice to avoid excessive recordings. If you’re more concerned about vandalism, motion detection might be more suitable. Some newer dashcams offer “buffered parking mode” which constantly records a short loop, and when an event is detected, it saves a few seconds before and after the trigger for comprehensive coverage.

Choosing the Best Dashcam for Parking Surveillance

When selecting a dashcam for parking mode, consider the following features:

• Parking Mode Functionality: Ensure the dashcam explicitly supports parking mode and offers the desired detection method (motion, impact, or both).
• Image Quality: Look for a dashcam with high-resolution recording (1080p or higher) for clear and detailed video.
• Wide Viewing Angle: A wider viewing angle captures more of the surrounding area.
• Low-Light Performance: Excellent low-light performance is crucial for recording clear footage at night.
• Reliability: Choose a reputable brand known for producing reliable and durable dashcams.
• Loop Recording: Ensures the dashcam continuously records, overwriting older footage when the memory card is full.
• G-Sensor Sensitivity: Adjustable G-sensor sensitivity allows you to fine-tune the impact detection threshold.
• External Battery Pack Compatibility: If you opt for an external battery pack, ensure the dashcam is compatible.
• Hardwiring Kit Included/Available: Check if the dashcam comes with a hardwiring kit or if one is available separately.

Here is a table summarizing key features for a dashcam used in parking mode:
