An Extra Layer of Safety on the Road

Hybrid Parking Mode & Low Power Mode
Keep your vehicle safe while parked with the Hybrid Parking Mode. Motion and impact are automatically detected, triggering instant recording. For battery-friendly protection, Low Power Mode ensures the dash cam enters standby while parked, waking up in 2 seconds when an event occurs. Perfect for long-term parking or rideshare drivers.

Vehicle Battery Protection
The dash cam offers two methods to prevent battery drain in parking mode.
Preset Time or Voltage
The camera automatically stops parking recording based on preset recording duration or voltage cutoff.
Hardwire Kit Cuts Off
The hardwire kit will automatically cut off power supply when it detects a low voltage.
Low Power Impact Detection
This parking mode features very low power consumption, preventing battery drain. When the vehicle is turned off, the camera switches to standby. Once detecting an impact, it will wake up in about 2 seconds and start recording for one minute. It captures theft, hit-and-runs, and other incidents to safeguard your car with vital evidence.
Hybrid Parking Recording
A combination of two parking modes: time-lapse 1fps and impact, low bitrate and impact, event detection and impact. The hybrid mode begins with time-lapse 1fps, low bitrate, or event detection, and switches to impact detection based on the cut-off time or voltage.
*Cut-off Voltage is only available with the HK6 hardwire kit.




Loop Recording & Auto Emergency Lock
Seamless loop recording automatically overwrites the oldest footage with the newest, while the G-sensor locks video during collisions. This ensures you capture and preserve critical events without manually managing files.
Ultra-Slim Coaxial Cable
Easy Installation and Anti-interference
A329S features premium super slim coaxial cable and miniature connectors for a neatly hidden installation. The coaxial cable is less susceptible to electromagnetic and radio-frequency interference, avoiding disturbance to other in-car electronic devices as well. What’s more, the cable enables higher bandwidth transmission and transfer rates, regardless of its length.
Dual Type-C Car Charger & Easy Installation
The included 45W dual Type-C car charger powers the dash cam and charges other devices simultaneously. Ultra-slim coaxial cables ensure neat installation with minimal interference, perfect for any vehicle type.
Circular Polarizing Lens (CPL) & Optional Bluetooth Remote
Reduce reflections and glare with the CPL filter, included for the front camera. Optional Bluetooth remote control lets you protect clips instantly with customizable buttons for added convenience.
The front and rear cameras support CPL filters.
