I've done quite a bit of research on this. I didn't want a system with a monthly plan so the local storage/security was very attractive, as was the claimed 365 day battery life and 2K images. So the installation was easy and well thought out, the hardware seems solid and of high quality, so that my enthusiasm continued. I set up the cameras and then installed them = in the right places. 1st area. This was a big problem. Range varies by environment, but my house is a typical wooden structure and the camera couldn't get a reliable connection at 40 feet one-way (through three walls with ledges in the way) and, worse, just 15 feet from my front door. Moving the base to a less convenient location got it working, but the signal is still not as strong. I don't know what frequency it uses - it doesn't use WiFi, but presumably a lower frequency with less power that might have better range. 2. Start time. Understandably, in order to conserve battery power, recording and transmission are not possible until activity is detected and the camera is turned on. This means that activation is fully controlled by the IR motion sensor. As such, activation isn't possible until the IR sensor detects a heat signature, even when there's a lot of motion in the frame, so you won't see anyone approaching until they get close enough and may already be past. Even when it's detected, there seems to be a delay in turning on the camera and then connecting to the base, as the first second or two (which is all it takes me to get out the front door) is missing, and that can be a critical period - when someone's face is showing. While it can be useful in some situations, it's just not worth it to me. If it works as expected it'll be a good deal - I got 4 cameras on a deal of the day but it just isn't responsive enough to be useful. It's disappointing for what is now the 3rd generation of Eufy. The actual image quality itself is really good - better than others I've tried, so this is even more disappointing.
