The DDPai Z50 is inexpensive and well-built, but the arbitrary 25 FPS limitation and lack of polish on the firmware keep it from being a hit. Some features like the super capacitor are generally only found in more expensive cameras, and even adding the optional 1080p rear camera keeps the price under $140. While this camera at least turns on, records and turns off with the car, other options in this price bracket are more mature software wise.
