I'm not sure using common or garden variety PIR's would be a wise choice. The cheap PIR's will probably cause you a lot of grief in terms of false motion detection. I own a Dahua DVR and use Optex http://www.optexamerica.com/security-products/lx-402 commercial grade PIR's as input to my security system which is a HA Omni Pro II system. The input from the PIR's is sent to the Dahua DVR by the security panel. I used the Optex brand PIR's for more than a decade with my security system and they have proven to be 99.9% accurate. So, I decided to use the PIR output via the security system as input into my Dahua DVR. I've owned the Dahua DVR for about three months now and have no false motion detection issues with this setup. Although I have not tried it, I do believe that these PIR's can be used directly as alarm inputs to your Dahua DVR.

The PROLINE specs are as follows: The PROLINE D1 Resolution(720x480) Each channel Records Simultaneously at 7 FPS MAX, 60 FPS for the whole unit and the FULLD1 has D1 Resolution(704x480) Each channel Records Simultaneously at real time 30 FPS MAX, 240 FPS for the whole unit. I have two dome cameras installed at my front/back door and need good facial at both doors. Thus my question is: Can the PROLINE give me good facial recognition if I devote these two cameras to D1 and the remaining three cameras to CIF if this type of resolution split can even be done? Also, 7 FPS seems really slow. It's my understanding the a TV picture is 30 FPS. Thus at 7 FPS it seems that the picture quality may not be all that great. Please correct me if I'm wrong. Thanx

I've been using Zoneminder which is a Linux software based DVR. Unfortunately, there isn't any easy way to interface the PIR security zones from my home security system to the Zoneminder application. I'd rather make a fairly substantial investment in my DVR to provide a high quality resolution on two of the channels for which I would require good facial recognition. These two channels would be at the front and back door. In other words, I'd rather make a one time investment in a quality product rather than go with something inferior and then realize later on that I have to upgrade. Bottom line, I'd have to say it would be a once and done deal. Facial recognition and internet access using IE and possibly Mozilla Firefox are high priorities.

I'm looking for a DVR that will support up to 8 channels. It's my understanding that Dahua is a very reputable brand. Unfortunately, I believe that the Dahua DVR is sold in the U.S. under other brand names. Thus, can someone recommend a brand that is truly a Dahua DVR? Otherwise, can someone recommend an alternative quality DVR? I currently have 5 cameras. four of the five cameras have a horizontal resolution of 650TV Lines. The fifth is a dome camera installed on my front porch which I believe is 560 TV Lines. I will need facial recognition quality from the dome camera on the front porch. Finally, I wish to input Passive Infra Red motion detectors to the DVR to start recording of the various security zone areas when PIR is triggered is triggered in that area. Any advice will be greatly appreciated.
