I am totally sold on these little home cameras. Wow!! They are truly a magnificent product. I'm very, very impressed. I've had them for roughly 3 weeks now and they pick up everything! I am using them inside the house facing outside. So there is a lot of motion they are detecting and they never miss a beat! I've already captured some things that are very worthy of reporting. I am using mine with the 32GB SD card, which fills up in roughly one week. However, it's easy to reset! Just click on the SD card within the settings of each camera and reset the card. It will erase the videos and start over. Super simple! The picture quality, sound quality, and the options within the settings of these cameras make them ideal. I will definitely buy again, and I would highly recommend!As for customer service, I had one particular camera in my pack of four that would not reset or connect to wifi. After lengthy trouble-shooting with my provider and the camera, the camera was the common denominator in all the results. I spoke with an rep who connected me with the manufacturer. They took my info, I submitted the form online, and they quickly sent me a new camera free of charge! I was very impressed! They were timely and professional and it was an easy process as well.The only con I would say they might have is they pick up motion irrespective of what is moving. It could be a bird flying, a tree branch, or even reflective lights at night. They will alert you to it all. So there are a lot of false positives. But that's okay with me. I'd rather have a camera that is too sensitive rather than one that misses important things. With these, I know for certain they will NOT MISS anything!! I see it all!!Can't speak well enough of these little cameras. They are IDEAL. If anything changes I will update this review accordingly. For now, all is quite well. I'm 100% satisfied.
