Guide to Efficient Parking Monitoring with Dash Cam Working Modes Configuration Safety Tips

Parking monitoring function of dash cam is mainly achieved through two modes, each with unique advantages and limitations. To achieve efficient parking monitoring, it is essential not only to select the right functions for vehicle mounted dash cam but also to pay attention to power supply, installation settings, and risk avoidance.

Parking monitoring function of dash cam is primarily implemented through two modes:

Collision Sensing Mode (Triggered Monitoring)

HD dash cam is equipped with a gravity sensor that automatically starts recording and saves videos when the vehicle is subjected to collisions or vibrations (such as scratches or impacts). It typically records for 1-3 minutes and then pauses.

Advantage: Energy-efficient, preventing battery drain caused by long-term recording.

Disadvantage: Only records the moment of collision, unable to cover prolonged abnormal situations (such as prolonged surveillance or theft preparation).

The dash cam is connected to the vehicle's constant power supply (a power source not controlled by the key) to continue recording after the engine is turned off. Some models support loop recording (overwriting old videos).

Advantage: Completely records all activities during parking, suitable for high-risk areas (such as unattended parking lots or remote roads).

Key Conditions for Achieving Efficient Parking Monitoring
Customers primarily want to identify core elements such as hardware, power supply, and installation.

Functional Requirements for Dash Cams

• Time-Lapse Photography: Records at a low frame rate (e.g., 1 frame per second) to compress video size, save storage space, and ensure continuous 24-hour monitoring.
• Low-Light Image Quality: Equipped with starlight-level sensors or WDR (Wide Dynamic Range) technology to ensure clear capture of images (such as license plates and facial features) in low-light or dim environments.
• Parking Monitoring Mode Switch: Supports setting collision sensing or continuous recording modes via the menu. Some models allow customizing sensitivity levels (e.g., high/medium/low vibration trigger thresholds).

Additional Functions for High-Intelligence Dash Cams

• APP Remote Monitoring: Connects to mobile phones via Wi-Fi or 4G modules to view parking footage in real time and receive alarm notifications (e.g., smart models like Xiaomi and 360).
• Battery Voltage Monitoring: Automatically cuts off power when the vehicle's battery voltage drops below a set value (e.g., 12V) to prevent power loss that affects starting.

To address customer concerns about insufficient device battery capacity, Great-will dash cams do not have built-in batteries and are directly powered by the vehicle's battery. They are connected to the vehicle's fuse box via a step-down cable to draw constant power (e.g., ACC power requires a delay power-off module), solving the problem of insufficient battery life. Meanwhile, the device is compact and highly concealable, preferably installed behind the vehicle's rearview mirror or on the windshield to avoid obstructing the driver's view while ensuring the lens covers the front of the vehicle and both A-pillar areas.

Parameter Configuration Recommendations

• Resolution and Storage: Choose 1080P or 2K resolution, paired with a high-speed TF card of 256GB/512GB or more. In time-lapse photography mode, a 64GB card can store approximately 7 days of video.
• Loop Recording Interval: Set to 3-minute segments for easy quick location of key videos.
• Alarm Sensitivity: Set to "medium" for urban parking to avoid frequent triggers (e.g., pedestrians passing by or vehicles driving past), and "high" for suburban or high-risk areas.

Video Management and Evidence Preservation

• Emergency Lock Function: Collision-triggered videos are automatically locked to prevent overwriting by loop recording.

Hardware Durability

• High temperatures inside the vehicle in summer (up to 60°C or higher) may cause the dash cam's battery to swell. It is recommended to choose "capacitor-type" models (no built-in battery, started by a supercapacitor).
• Regularly check the status of the TF card to avoid recording interruptions due to poor card slot contact or card damage.

The core of what customers want to know is: how to achieve low-cost parking safety protection through dash cams without damaging the vehicle and in compliance with laws and regulations, while avoiding issues like battery drain and data loss caused by improper operations. It is necessary to provide solutions covering the entire process of "function selection → power supply scheme → installation settings" and emphasize the core of "efficiency"—precise triggering, clear image quality, and energy-efficient stability.
