1. It slows down the computer significantly2. Can't get it to do exactly what it's supposed to do3. Came with 2 cameras but only one can be used at a time4. Causes significant interference with my wireless internet no matter what channel it is placed onHow can you sell a person 2 cameras and only one can be used at a time and on top of that you have to be physically at the device to make the switch so its a waste for remote users.
