Hi,
I had the Blackvue 650s 2 channels, even thou I was happy with it I purchased the Thinkware 770 2ch.
The quality on the the Thinkware is better than the Blackvue.
Parking mode is great, I use a Cellink B V2 battery which keeps the parking mode going.
I have turned a lot of the features off as I did not see the need for them ie lane departure and forward collision warning.
I love the time-lapse feature which is what made me purchase the Thinkware and the better video quality time-lapse does not give you audio.
I things I miss that was available on the Blackvue
I was able to log into dash cam whilst it was still recording, Thinkware stop recording once connected with a smart phone.
I was able to log into dash cam when in parking mode, Thinkware needs to come out of parking mode to do this.
I was able to use Blackvue App to connect to dash cam for live streaming when my car was parked outside my house or at work and was connected to wifi, this is the cloud feature on the Blackvue. Thinkware does not have this feature.
love the design of the the Thinkware dash cam, sits flush against windscreen, had to use polarize lens on Thinkware but had the same problem with Blackvue.
The Thinkware is a fraction cheaper.
The buttons on the Thinkware do not stand out, when turning on wifi you end up pressing wrong button, easily sorted by sticking Silicone/rubber buttons on the wifi button so you can feel which button you are pressing.
The SD card is very easy to remove, the Thinkware volume is loud compare to the Blackvue,
Think has 3 wires
red for battery live, yellow for Acc, black for earth, goes into parking mode when car is turned off.
Where the Blackvue only had 2 wires, + and -, goes into parking mode when it does not detect movement.
Thinkware has internal storage, not much, but handy if SD card get damaged in crash.
Thinkware dash cam easy to remove from mount just slide out.
When getting in the car it states 2 events detected, when I was exiting car and when I came back to car.
If Thinkware can add another acc wire so it can connect to the dome light when car is unlocked which will bring it out of parking mode and not show the events when exiting and entering then that would be nice.
