If I could give zero stars I would. It often won't turn camera on or off. Sound on or off. Disconnects. My son has been up several times in the middle of the night and it doesn't alert me and turns the sound off all together. I heard from across the house without the camera. Unreliable. Awful and dangerous. Save your money and buy a much cheaper more reliable version. I do not feel safe using this for my son. I've been troubleshooting these issues for a while. DANGEROUS
