Connecting to them sometimes takes a long time sometimes it just spins saying connecting until I exit the app .I had to take the first two sets back to the store because one of the cameras didn't work in each set the third set all three cameras work but sometimes it takes a long time for them to connect so every time I use them it's a toss up as to whether or not it's going to connect and show me the picture .It blurs at about 8 feet if I zoom in
