Our Favorite Things about the A139-2CH

  • Reliable 2K 1440p front and Full HD 1080p rear recording with the Sony EXMOR R STARVIS image sensor utilizes back-illuminated pixel technology and "realizes" high picture quality in visible and low light. Remove the worry of not capturing incidents due to poor lighting conditions and drive with confidence that you've got a reliable dashcam defense!
  • Dual Band 2.4 GHz & 5GHz WiFi capability allows for a stronger signal transmission from the camera to your mobile device, allowing you to access video footage faster!
  • VIOFO’s built-in super capacitor protects your recorded files from being damaged in the event of sudden loss of vehicle power and will provide enough power to safely write and store data to the SD card before powering down. In the unfortunate event of an accident, rest assured your video footage will be there to tell the tale!
  • With the A139-2CH’s Parking Mode enabled via hardwiring the unit to the fuse box or having the camera constantly powered by a 12V outlet, its buffer recording ability captures 15 seconds before an event (motion detection, collision) as well as the 30 seconds afterward. Never miss a thing with 24/7 protection of your vehicle and peace of mind for yourself!
  • See something you need to save as an event? Record manually at any time with the Bluetooth remote (optional) and save the footage in a specific event file for later viewing. The VIOFO unit is always ready when you are!
