BCHobbyist Modified Firmware is always created in multiple Bitrate values for video clip size control. The low 22 & 24Mb/s Bitrate MODs create clips at similar size to stock firmware.
None of my A129 or A119S or A119 Pro or A119 Dashcams have failed and I
create and test 100's of MODs at low & extreme Bitrates including
A129 Duo at 35Mb/s and none have failed or
even caused failed startup or file corruption. Many reported issues can
be attributed directly to not Formatting new memory cards or not
Resetting Defaults after update or card Brand/Type isn't 100% supported
in Firmware or using Fake/damaged cards or Low Power source. I've been using older
Lexar 64GB TLC C10 U1, Samsung 64GB TLC C10 U3 and newest Viofo 64GB
C10 MLC U3 cards with zero issues, considering I push the hardware
beyond my own safe limits to probe the MAX i'm actually surprised nothing
has happened. I did of course modify each Dashcam by removing the
black acetate tape over the cooling vents as shown in my old A119S Tips #1 video. My MODs are very conservative compared with others, use at your own risk, and always start with 22-25 Mb/s MODs since Viofo already uses these values.
All VIOFO and Modified Firmware versions can be updated or downgraded changed or reflashed over each other from any version without issue. Recommend everyone load Official Viofo version for 2 weeks then compare against MOD of choice. Always save footage from stock firmware on all new Dashcams for possible Lens defect evidence for returns.
Anyone reading this website worried about MODs causing permanent damage
must understand running official 20 Mb/s firmware in
HOT regions in extreme temperatures or leaving Dashcam in Parked car with or without
Parking Mode enabled will reduce the lifespan of the device if internal component temperatures reach 70C or higher.
In extreme temperatures avoid using WiFi or 60fps settings since each generate 3x more heat than MODs.
Most effective ways to reduce Dash Camera heat is:
- disable WiFi
- disable Bluetooth
- avoid 60fps and use 30fps
- don't use Parking Mode in full sun for hours
- remove any external or internal tape blocking cooling vents
- avoid windshield sun reflector panels in parked vehicle with Dashcam mounted.
No Dashcams have failed using my MODs.
