If your video was working over the network on your computer and it quit but it still works on your monitor then you will follow these instructions.
1. Unplug the power from the back of the dvr.
2. Waite 30 seconds and then plug the power back in.
3. Test to see if you can connect on the computer and see the video again.
The most likely reason that it quit working is because the power went out or a power surge happened at that location. If you want to help prevent this in the future you will want to get a serge protector with battery backup. If you don't want to spend the extra money to get the battery backup a serge protector will help some.
