I initially bought 2 cameras as security during a lengthy business/holiday trip. The wifi capability failed and was replaced within a week. Software for viewing the pictures allowed up to 4 cameras to be viewed, which was good when they worked. However, the cameras failed while I was away and even after being revived by a friend the wifi capability failed again very quickly. The supplied brackets were useless for holding the cameras in anything but one position.
Onreturning from my trip I returned both cameras for a refund which is why I am now looking for replacements.
