Initially, the kit was great. It has two small cameras, long cables and a separate security module. The camera does not drain the car battery. However, video quality is mediocre. It is grainy and difficult to make out details. The battery drains quickly so is useless parked more than over night. This is with an add-on battery (which is a great feature) but I figure there needs to be about 6-8 backup batteries to last 3 days. Whenever there is a FW upgrade the alarm beeps nonstop. It is still beeping now as I am looking for a different camera. Customer service was poor since they barely understood my problem and could not respond effectively. I even got Blackboxmycar's battery charger, which is great, and an extra backup battery, which only lasted a few hours. Otherwise, there is no way to charge these drained batteries from the wall outlet. For the money spent it was very disappointing.
