“I have the Viofo A129 Duo Plus. I have the screen set to shut off after 30 seconds. It only comes on again if it records an "emergency" or if I push the button on the dash cam.”

Top Criticism

+2 pts

“Before you go with Viofo. I just made a post literally 30 seconds ago about it. My Viofo camera is fried and now longer works. The GPS module is 100% broken and the side power inlet is in and out with being reliable. There are tons of threads about my camera (VIOFO A129 Plus Duo), and other versions having issues with keeping power.”

Feature Checklist

Feature	Plus Duo	Viofo A329
Proven durability (3+ years)
Best 2K value under $200
[Included Anti-Glare CPL & Versatile Cable Options] A CPL (Circular Polarizing Lens) is included and attached to the front lens of the dash cam, effectively reducing reflections and glare from glass and road surfaces. This results in a significant enhancement of image quality and contrast across various scenarios. The camera comes standard with a 6M rear cable. If you require a longer customized 8M or 10M rear cable for your vehicle, you can find it on the VIOFO website.
Comprehensive Bundle Benefits: This bundle combines the A129 Plus Duo's high-resolution recording with the HK3 Hardwire Kit’s parking mode capabilities. The hardwire kit ensures uninterrupted surveillance with options like Low Bitrate recording and automatic event- triggered capture.
INTEGRATED PARKING PROTECTION: The VIOFO HK3 ACC Hardwire Kit allows the A129 Plus Duo to utilize advanced parking modes, including Auto Event Detection and Time Lapse. It also features low voltage protection to safeguard your vehicle’s battery.
[Impact Detection Power Saving Parking Mode] The A329S dashcam supports an ultra-low-power parking mode to prevent battery drain. Once a collision is detected, it starts recording instantly. These features minimize battery drain while ensuring continuous monitoring when your car is parked. These modes can be easily activated using the HK4/HK6 Hardwire Kit（*Note: The hardwire kit is not included).
[Support Up to 4TB SSD or 512GB microSD] Say goodbye to storage limitations! The A329S supports external SSDs up to 4TB or microSD cards up to 512GB, allowing for uninterrupted recording for over 3 weeks. Perfect for long road trips without constant overwriting worries. We recommend using the optional VIOFO Type-C SSD cable. (*Note: microSD card and SSD storage are not included. )
[Simple Installation Without Interference] A329S 4K 60fps dash cam features premium super slim 2.8mm 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.
