Blackvue DR650GW-2CH: rear camera color problem

[DR650GW-2CH]

Hi, has anyone came across the rear camera issue on DR650GW-2CH as I posted below:

This issue comes every now and then randomly. My first set was having issue and I raised this concern to the vendor. He then replaced a new unit for me.

After a day, the same problem happens again.

This is annoying that every time I start my travel I have to check the rear camera to ensure it is working properly.

Some say it could be cabling issue. When the issue happens, I simply turn the dashcam OFF and turn it back ON. Then it solves by itself without touching any cable. Hence I guess this may not have anything to do with the cable.

Would anyone extend assistance here?

I had the same issue with 550, but it wasn't so often as you mentioned. Maybe I had this problem twice within the year I had a 550. After I got a 650, I never faced this problem. Did you upgrade the firmware to 1.001 and try?

 

[DR650GW-2CH]

Yes, my replacement unit has been upgraded with latest firmware 1.001 (which has the extra features like speed alert, vehicle identity, auto restart after applying changes, etc). However, I still got the issue once in the 2 days usage.

Not sure whether temperature plays a role in this problem.

My car usually park under direct sunlight and everyday it can easily reaches up to 65'C (150'F) in the cabin. Therefore I never use the parking mode worrying it will damage the dashcam (i.e. overheat) especially Pittasoft never stated about the overheat protection in DR650GW-2CH.

I've seen that only happen once. It was after I first installed it on the first day took a test drive around the block with it. I never saw it do that again in the 4 months continuous time frame I've used it. Not sure what happened or what I did differently but it has been working fine ever since.

THIS IS THE PROBLEM OF AMBIENT TEMPERATURE 90%

The problem is not related to temperature. I tested the camera when outside temperature was about 0°C and the temp inside the car was only a few degrees.
It appears, however, that the problem may be related to WiFi. When WiFi is configured to be activated automatically at power-up, the problem occurs about every second time I start the car. After turning off this feature, and instead activating WiFi manually after power-up, the rear cam seems to be working each time, but I have to perform some more testing before reaching a conclusion.
