    I don't have any software yet, I'm in the planning phase Starting to look like that Rivatech PTZ plus several PIR sensors might be the way to go. Depending on the camera price, of course.

     

    Regarding the area, I'll try to make a map/diagram for and post it here. I have an aerial image of the yard somewhere, so if I can find it, I'll use that as base.

    I use Digifort software in combiation with Riva cameras. This software supports VCA metadata from Riva cameras.

    Also, Exacq should support, but i'm doesnt test this combination.

    I would recomend this camera with video content analisys:

    http://www.rivatech.de/images/pdf/RC4100-2212-36-EN-V1.02.pdf

    The main difference - autaotracking will be activated on specific inteligent video motion detection violation parameters. Also, regarding VCA, will not be triggerd by moving trees, etc. Camera will not follow, as an example, moving vehicles, dogs, but will follow humans. Also, will track the same object in situations, when another moving objects will appears in camera field of view.

    Hello,

     

    I have few questions about Dahua equipment.

     

    Does DH-SD6582/82A-HN 2Mp dome has privacy masking? How much privacy zones?

    Does 4 channels NVR supports 3rd party IP cameras (ONVIF)?

    Does DSS software can control "Monitor wall"?

    Does DSS software have possibility to receive streams from 3rd party cameras (ONVIF)?

    How DSS usualy operates with streams from cameras - via NVR or directly from cameras?

     

    Thanks in advance

    Also you can try Digifort. At Digifort site you can download one month demo, also, can find good servers power estimator:

    http://digifort.com/design_tool

    For big systems, Digifort supports monitor wall solution, (Virtual Matrix).

    Licences cost is based on cameras quantity, but no MAC addresses, like Milestone.

    Also, encoders recomendation:

    http://www.rivatech.de/index.php/en/products/video-encoder

    Digifort (Professional and Enterprise versions) supports video analytic from this encoders and simple motion detection, so less processing power on server will be used.

    Ther exist some devices in the world:

    http://www.siqura.com/optelecom_C01/default.asp?comid=6&modid=368&sessionid=-1&crumbsearch=1

    But, this is not a universal solution. I will reccomend to use VMS client software on smartphone and WiFi. Or, IP cameras with analog output. For final focus settings best way - IP cameras with remote focus or autofocus functionality.

    I recently installed 4 outdoor 1080p HD cameras at my house

     

     

    ground loop .....cat5 ..... with HD ???

     

     

    more like poor coax or run is to long.. which cameras do you have ?

    He has HD-SDI cameras

    Alex, HD-SDI - it's also digital signal (800 mV (±10%) ), and analog ground loops will not cause this effect.

    This can not be ground loop problem directly. I thing, problem in power supply.

    Also, jrc, are you shure, tat you have 1080p HD cameras? It looks, like you have "tradditional" cameras....

    Can you write the cameras model?

    Ohhh I didn't realize motion recording is actually more CPU intensive than continuous recording. But now that I think about it, that makes sense.

    that partly depends on the recorder and how it implements motion detection. on the systems i use, it's a very minimal performance hit.

     

    also, many cameras have their own motion detection, and the nvrs that work with them just take the signal from the camera... so again, it's little or no actual performance hit on the nvr end.

    This depends, how NVR do motion recording. If NVR use motion recording, based on motion detection from camera - it's like no aditional load on NVR. If NVR has it's own motion detection - processor load will increase dramatically, but also depends on stream from camera - compression format (mjpeg, H264, MPEG4, etc.), and on incoming video stream resolution and frame rate.

    I want to thank all you guys for replying with suggestions. After trouble shooting this problem for two weeks and trying all the suggestions. I decided to try a ground loop isolator. Even though some people said they don't work and some say they do. Well.......it WORKED!!!!! This little $15.00 (US) part solved the problem.

    I'm was right

    Mobotix M15 when is that shipping 2020?

     

    I better get my order in now, beat the rush.

    I'm see M15 at IFSEC last year. 5MP sensor sensitivity is better, but still has dynamic range problems. But, no implementations on B/W sensor. Instead of B/W sensor will be thermal sensor This not a joke.

    Mobotix cameras is not bad. But Mobotix is good "still", but not "movie" camera

     

    buellwinkle, great blog (y)

    I would agree the Mobotix M12 color sensor is bad in low light, but they typicaly sell it as their dual night version, with a color and b&w sensor. The b&w sensor is excellent in low light with very low noise. To me it was the leader for a long time but other cameras are catching up, so Mobotix has to step up their game. The M15 which I beleive replaces the M12 may be that camera with 5 MP.

    In my video You can see both Mobotix sensors comparsion - Color and B/W. B/W sensor has better sensitivity, but not enaugh, but dynamic range is worse, than color sensor....
