Set-up was about as simple as it gets. The night vision is impressively clear, and the day vision colourful and bright! Mounted 3 of them, and they offer ample video coverage for my lil quarter acre area. The audio options allow me the luxery of giving commands to my working dogs and flock regardless of where I am. Absolutely love the ease of use, clarity, remote access, and versatility of these units. Have recommended to several others already!
