Great cameras. Easy to set up. Great for the price. The only downside I have seen so far is that if I try to talk to my from my phone to the camera, the speaker on the camera is very low and hard to hear. However, if I use my tablet instead, the speaker is nice and loud. (Phone is Samsung Galaxy S5, tablet is Samsung Note 10.1). I use once camera to keep an eye on my dogs and the other I plan to put on my front porch so that I know when I get packages. The app will alert you (if you want) when there is motion or sound and send you a notification. Perfect for the holiday season when we have alot of packages being delivered. I know instantly when they arrive, and can get them or call a neighbor to pick them up for me. Extremely easy to set up, phone app guides the whole process that is only a few steps long. Will buy more!
