    can't say for your situation, not sure it will work correctly, this cam has some strange behaviour with fixed shutter, mine is installed on a very bright area, and the sun shine directly on the camera too (backlight compensaton is great i have to say...)

     

    watercolor effect is common with H264 in low light in general ...

     

    go for a p3364 if you can add some white light you won't be disapointed

     

    do you need WDR?

    So you are saying that in night mode you can't set the shutter speed to something like 1/100?

     

    yes unless you use a fixed shutter of 1/100 for day & night = exposure problem when scene is too bright during day

     

    When you say that the IR results are not exceptional, may I ask what you are comparing against and is there something that you would consider exceptional (box preferred, but can live with dome)?

     

    They are sold for super low light cams but they are not unless you use a slow shutter and a lot of gain (noisy image...+noise reduction effect that can't be managed)

     

    also if you turn on WDR image is worst in low light

     

    i have exceptional result with my old bosch ltc0620 analog cam (i'm always in color mode), ok it's an analog cam...

     

    i have similar result to the p3364 with my Mobotix if i use the same 1/30 shutter mode + IR,

    (but as i like crisp images my mobotix use a 1/250 shutter so every cam has a 150w PIR flood light over) ...

    Q1604 & P3364 are correct if you have a decent amount of white light, the color mode is great but if you use IR results are not exceptional

    i have one p3364 outdor and a q1604 indoor

     

    -at night i have a lot of motion blur (max shutter can't be set above 1/30sec)

    - it seems that on axis cameras their is an anti noise effect that can't be removed or reduced at night,

    -if you want a crystal clear image you have to set a very slow shutter speed like 1/1sec

    if you had an avigilon pro 16MP you could have catched the face perfectly @ 0.05sec on the video, you could have catched the serial number of the bike wheel , can't you put 8000$ on a camera?

     

     

    some clues:

     

     

    your cam is too high (use an anti vandal dome and place it lower)

    your resolution is too low (use megapixel cam)

    your angle is too wide for this low resolution (your pixel per foot is too low for facial recognition)

    your recording codec is not the best for cctv (use Mobotix Mxpeg or Avigilon Jpeg2000 if you want the best detail)

    May I know what kind of VMS are you using?

    Thanks.

     

    i use milestone Xpress on this entreprise level instalation

    hyperthreading is supported by milestone smart client so you take full advantage of the I7 3770

     

    i would not recommand to OC an enterprise server, if you don't have correct voltages issues could appear, it's not like having more fps on a game...then a crash during a party... just imagine that the recording service freeze due to a bad OC... i preefer to put an extra $100 on the more advanced cpu and run it at stock, the frequency is not the key to more performances, be sure to have good memory, strong & fast hard drive correctly cooled and a decent graphic card

    Hi lemike41,

     

    Thanks for you input.

     

    if you want to speed up your milestone system and if you dont care about noise but want better perf :

    use a dedicated disk for recording (i recommand a 250Go velociraptor) and another dedicated disk for archieving (like a caviar black)

     

    i have this kind of setup for 16 x D1 cam and 11 x 1.3MP cam on an i7 3770 + 8go of ram, it runs like a charm even if i fast reveiw all cams simultanously

     

    According to your last statment....

    It seems like system with i7 CPU is capable of handing 25-30 channels of real time video monitoring

    and recording with hitting Maximum CPU usage. But then it depends on what kind of resolution of

    decoding and encoding the system is doing.

     

    Thanks.

     

    the latest i7 are killers

    my cpu usage is approx 25% while viewing & recording, and approx 10% while recording only, i have 3 monitors, 1 for the desktop, 1 with 6 cams (6 x 1.3mp) and 1 with 12 cams (7 x D1 and 5 x 1.3MP)

    i can't reach 100% even if i fast review all my cams

    from what i heard , no M14 before q2 or q3 2012

     

    mobotix is working on a covert model, project code S14 (S for Slim) :

     

    Mobotix revealed that its will be releasing new hardware with an ‘S14’ product name within 2012.

     

    The ‘S’ refers to ‘slim’, hinting at a range which will employ secret surveillance monitoring, and an overall smaller footprint.

     

    Ekerot suggested the industry should expect a range of “flavours” from the S14 family.

    The solution will be built on a completely new product board, P3. It is a future-proof board that we hope will take us into the next eight to 10 years, and will allow us to build a whole range of new products on the same hardware
