I bought these cameras to supplement a hard wired system. I did not have high expectations, however after experimenting with the cameras indoors I quickly deployed them outside. The setup has the base station hard wired into the router. One camera is on the far side of the house (brick exterior) and gets a 43% signal at about 75' distance including 3 interior walls. The other is much closer and the signal is 90%. Setup was a breeze, image quality is great during daytime and pretty good at night. With a lot of cameras you will get issues where the IR LEDs will be at too high an intensity and people faces will be all highlights without much contrast. These cameras seem to have Smart IR functionality where based on overall exposure they adjust the LED power that yields good images with people and moving subjects in them. The notifications work fine (iOS), and sometime you may have to manually go to the "Playback" function of a camera to see the footage you were notified about. The human detection is great (one camera is mounted high up above a doorway) and even at that angle is able to detect humans going up the stairway below. Battery life has been great (still above 90% after 3 weeks) but YMMV, if you mount these cameras in high-traffic areas with a lot of motion, they will be triggering and recording all the time and that will likely eat up more battery. I like the fact that there is no need to subscribe to cloud storage, and I have a 128GB endurance card in the base station.Customer service has been well above average, the exchanges happen within the message center in the app and the responses are prompt and they know the tech details on the system. One of my cameras had red/green/blue lines and after troubleshooting was diagnosed as faulty, a replacement was promptly sent and received within 3 days.Overall, this is a neat system with great picture quality, good battery life and excellent detection capabilities. Time will tell if the cameras last in bad rainy weather, mine are mounted under cover on the porches.
