A while back we were introduced to Pittasoft when we reviewed the BlackVue DR650S-2CH dashcam. Overall we were quite happy with the performance, but there were a few improvements we would have liked to see. When I recently heard the DR900S-2CH was coming out, I jumped on the chance to look at the new and improved device. The biggest improvement on paper over the DR650 system is now the primary camera is capable of 4K resolution and the rear is 1080P. But is this enough to justify you dropping almost $500 on a two channel dashcam? First let’s look at the features?



Features and Specifications:

As mentioned, the new BlackVue DR900S-2CH is capable of 4K resolution for the front camera and 1080P for the rear. In my initial review of the DR650S-2CH I was pretty happy with the front camera capturing 1080P. But 4K coupled with a wide field (162 degrees) of view should ensure this DR900S-2CH misses no details up front and performs significantly better than last time. I was a bit critical of the 720P rear camera in the original review, so again in this case the 1080P should be a big improvement on resolving license plates. Another annoyance was a relatively weak Wi-Fi; again this BlackVue delivers by upgrading the system to dual band. On paper the DR900S-2CH seems to be delivering on the few short comings we found in the DR650. Here is a complete list of specs from their site and from the manual.
