FYI, the AHD cameras can be changed between AHD and Standard analog video output by pressing and holding for 5 seconds the menu button.
This allows for compatibility with legacy systems, or connecting a handheld monitor for installation/focus adjustments.
Other issues I had with the 720p AHD camera setup is the DVR does not stream full resolution live video only the low resolution. Only 4 cameras per view and the 4 cameras must be 1-4,5-8,9-12,etc. No custom layouts. Playback of a recorded video would be at full resolution. Very limited network use of the system. Have they resolved any if this on the later releases?
When you say it doesn't stream full resolution live do you mean via the local video output or via the web interface/software? In the latter, you can right click and change stream. I'm not 100% sure on the local interface.
rtsp or ipolis access. i can't remember if live full resolution worked via explorer. local was not an issue.
Both Samsung AHD cameras defaulted to slow shutter (1/5 second exposure), requiring users to change to 1/30s via the OSD menu.
Is this definitely undesirable as the default, since it doesn't necessarily change the shutter speed, but only allows it to get slower as the scene grows darker?
As you point out it doesn't seem to have much of negative effect until the last scene without IR. Do you feel that particular scene would improve with a faster shutter and more gain instead?
