If a network camera keeps restarting displaying from time to time the Cannot connect to camera message then do the following:

- Install the latest service pack for your operating system.
- Try lowering the camera frame-rate and/or image resolution.
- Uncheck QoS Packet Scheduler in the used Network Connection Properties dialog:
