@Ben_Reilly The N2 Pro has 1080p quality for both front and in-cabin cameras. Quality is great for both day and night. As for being able to see license plates, yes for the front, but no for the in-cabin camera. There is no way to see that far back out the rear window to see a license plate. I'm sure you would be able to see if the car behind you rear ended you.
There is actually a Flash sale going on now at Newegg for $159, regular price is $199 at Amazon.
Mods, I apologize if talking about a sale for another product is not allowed. Please delete if this is against the rules.
