Purchased Swann Professional Security System (DVR9-4200) two years ago. Within these 2 years the IR Night Vision began to go bad (poor night vision) on all 8 cameras. According to Swann the Infra-Red LED's have an average lifespan of 10,000 hours. I called Swann to order new IR boards (approx. $5.00). I was told they do not sell this part and I would have to buy new cameras at $79.99 ea. If you need a camera that works only half the time, this is the one to get.
No, I would not recommend this to a friend
