Great camera at an affordable price! I also have an S4 and truthfully it's built really well with more added features but you will pay more for all of that! If you need 4K resolution along with a motorized pan-zoom-tilt you'll need to get the S4. If you want to save some money, get the S340. It's a very functional camera for the price!
This is the second S340 I purchased for my house. Set up is easy, the app is easy to navigate and the pictures, video and sound are exceptional. Probably should've bought a 4 pack.
They work really well but when I'm in AI mode I will come out and find them turned all the way around facing the base and I have to manually move them with the app and I don't know why it does that.
Just a few of these covers entire exterior. Image quality is good, tracking works well, however at times motion does not trigger. Overall, am excellent choice.
