This is my 3rd Thinkware Dual Channel Dashcam. I have two Q800's and now the Q1000 for my new vehicle. The pros are Thinkware's high-quality cameras, both front and rear. Ease of use, but most of all they sustain the heat of Phoenix Arizona. With outside air temperatures reaching 118F, inside air temperatures of the parked vehicle can reach beyond 140 degrees F. The Thinkware cameras withstand the heat whereas others I've tested did not. I've had the Q800s running for four years now and zero issues, so it was a no-brainer to get the Q1000. The downside is the setup. It took more than 1.5 hours just to figure out the registration process. Luckily, I have a 12v battery pack and could work in the air conditioning of my house, as it was 110F outside when I started the installation. I watched the Vido on BBMC, and inevitably had to call them and Mark was very helpful at getting me registered and working. The installation of the front and rear camera of a Lincoln SUV actually took less time than the registration part. There are learning curves compared to the older Q800s. The Q1000 uses two new apps, but another pro is that the Q1000 quickly connects to a smartphone with ease! So, CHEERS to Thinkware for that improvement, whereas the Q800s are tough to connect to Wi-Fi on the smartphone. It's a lot of hit-and-miss. So overall, major improvements with the Q1000. The registration process needs to be made simpler.
