Ok. So I don't know if you have tried it on your DVR.. I did just try on my AMDV8m16-H5 8mp 16ch DVR and it failed. It does work on all my NVRs. If you tried the CGI off my link, there is a space between the http: // and just copy and paste adding in your IP and right date/time will just make it do a search...

Sorry I didn't understand that the timeline was so short and agree that doing a search in a short time does take even my ASP ending line way out there and have to use my scroll wheel to pull it in. So understand the issue better now.. I agree is kind of a PITA without a scroll wheel.
Don't have my 7108-AI DVR local to me right now to test on that one. I am still looking for a good CGI to work with my DVR for others that could use it on an DVR..
