JJK, this is the camera that I use to monitor the scope:
D-Link DCS-932L mydlink-Enabled Wireless-N Day/Night Network Camera
It is wired or wireless, has a mic so I can hear the mount and camera shutter when I image. Another nice feature is that if i start an imaging session in my capture sw and I hear some wind i can pause the session until it stops I dont have to be looking at the images as they come in. Real easy to access from anywhere with a browser or iPad/phone app. I do not know if the ir sensor will cause any issue with long exposure, I have not seen any with the short exposures I have been doing. Once you set it up you can unplug the power and plug it in anywhere and it stays on the network.
Thanks for the info. The IR light is ok. I'd check on the scope/mount between exposures.
