  1. Actually I have only analog cameras since about 7 years and maybee I will upgrade to a Dahua XVR and buy HDCVI Cameras to use with my existing installation cables. Which Dahua XVR 16 channels can replace my old Dahua DVR0804HF-U ? (I'd like to have possibility to add IP camera and also PTZ in the future.) What will be a good deal ?
  2. yes sure, I don't whant to buy another unit for the moment. Maybee, later I can move to a XVR, but for the moment it's not my priority.
  3. ok. Many many Thanks ! Have a nice week-end. Best regards

I'm not a "King" on CCTV System... I try to add the better analog Camera and not sure which one will be the good one because I can find I lot of possibility (for example on Ebay) but specification from seller are often Comic I think... What's the maximum Resolution compatible with this DVR on Analog input ? 700 TVL ? 800 TVL ? 1000 TVL ? I fund 2 Mp Camera but on CCTV Analog it's not possible 2 Mp or ?? Many thanks for help. Best regards
