  1. Don't know if you tried, but how responsive are they to adding support for new cameras? For example, if I had a Dahua and asked them to help support it, will they ignore me or help?

    I've always gotten a quick response, but have not asked them about cameras they do not support.

     

    In some cases I've found cameras that work that are not listed, and they have a few links to mjpeg listings on their site. Usually you can get the string from the camera manufacturer (e.g. Axis Panasonic whatever). You could try it on their demo SW which is free. Have not played around much with non mjpeg on VitaminD.


  2. You can get Bosch motion detectors that work pretty well for $20-40 and hook up to the alarm inputs on your camera and then set events to trigger off the alarm input instead of video motion detect. Analytics software like VitaminD would be great, but they do consume a huge amount of CPU power to do this, so make sure you have an adequate sized supercomputer

     

    Mike, how many cameras do you have on a VitaminD PC and what's the PC configuration. I always like the thought of using VitaminD, just wasn't sure my i3 PC I currently use can handle six 1-2MP cameras.

    Yeah, it takes some processing power but just buy a computer that can handle it.

     

    I have had up to 16 cameras (8 of them 1.3-3MP) running on an i7 does not even come close to using it all. Really an amazing computer. You also need to make sure to have a 1G NIC as the streams are all MJPEG. Don't know about an i3, i7 is not all that much more. My understanding talking to them is that the cores help. I think the i7 is also much nicer than the Athlon quad core I used to use.

     

    Above about 8 or 10 cameras will hang momentarily doing a refresh. The issue is HD writes! Took me quite a while to narrow it down to this. This can be SOLVED.

     

    It writes everything to the C:/ drive for crunching, then moves items of interest to the same or another drive if you have one. If you are trying to do it all to one drive it is just too much, recording and bringing events back.

     

    The trick is using a SSD for the main drive. I have it set up with an Intel SSD for C:/, and 1TB black. With that I can get over a month of storage. 5 yr warranty on the Intel.

     

    Same computer is also running 12 channels Axis camera station (separate bank of HD's), and 8 channels Milestone...

     

    The i7 is really amazing, and it does all that at around 100W...

     

    Someday I'm going to spend some time and do a post on VitaminD, it is much more useful than all the other VMS I've tried in terms of letting you know what is going on.

     

    A normal VMS is nice for going back on surrounding events, or pulling a 3MP shot etc. ACS is pretty cool in terms of the amount of integration you can do (and it is rock solid stable), and Axis cameras are great in terms of multiple streams etc.

     

    The other option for VitaminD with lower end processors is crunching a CIF stream, and using something else for the constant VMS. This other method takes much less processing power.

     

    One final comment, using Axis cameras above 1.3MP is also possible with VitaminD. I have a post out there somewhere on how to do this.


  3. I dunno, works on mine frame rate is fine. I am doing it with over 8 cams, but scaled down.

     

    Here's some other examples I got from Axis a long time ago, maybe this will help you get something working

     

    var refreshrate=6; //SECONDS BETWEEN REFRESH

    var image="http://camera.no-ip.info:8080/jpg/image.jpg"; //IMAGE NAME

    var imgheight=470; //IMAGE HEIGHT

    var imgwidth=620; //IMAGE WIDTH

    function refresh(){

    document.images["pic"].src=image+"?"+new Date();

    setTimeout('refresh()', refreshrate*1000);}

    document.write('');

    if(document.images)window.onload=refresh;


  4. Hmm, works for me without blinking using firefox (granted, an old version) on a mac and W7. After the daily updates I said that's enough and disabled it back at 5.0.1. Also works on Chrome although I don't use that for anything else... I just have it set up as a shortcut on my browser so when I want to see the cams I can click that. After 30 seconds though the fan kicks on with this old macbook, have not tried dialing back the framerate.


  5. I tried the examples posted and got them to work, but it also does not preload the image so it blinks between image refreshes.

     

    Yes, I think the person who created that example, needs to review my working example.

     

    Don

    The person who created that is banned from the forums. Does work well with Axis Pansonic Arecont. Axis has some examples also if you contact them, looks very similar. Don't know about Acti as I gave up on that brand...along with Arecont...
