I bought 2 sets of these last week and they’re amazing. Build quality is good (compared to cheap ones I have had in the past) rear camera cable reaches the rear of my commodore wagon (just). I also hooked up the rear camera to my reverse lights (not needed to power it as it gets that from the front unit) but if you do attach the red wire it turns the hole front camera into a reverse camera when in reverse. Very handy. To sum up great footage, easy install, overall very happy with my purchase and would buy again. Also the wifi worked well on my Iphone AAA++++
