Eric,
Thank you for the rapid response and the spec sheet; I'd lost mine. I'll order another IPOB-EL4IREW shortly. I have a couple of areas to monitor that would be a hassle for IP cable runs.
That's right, I had to drop the output to 1080p to get rid of the black screen on this 1080p DVR. Lower resolution isn't an issue in that area, and it reduces wi-fi bandwidth scrunch. I'll be upgrading to an NVR, with more channels, and be replacing the HD-CVI cams with IPCs.
