    Really got into doing Home Theater, Phone Systems, Home Automation etc. for million dollar homes in Beverly Hills. Figure I had to learn something new.

     

    The Active Tech DVR is still only avalible as a 4 channel. I did figure out how to run it with a web browser though. You have to port forward port 80 also. For example, if you put the DVR behind a router and the DVR port setting for the remote Client is 6100 (default) and the IP is 192.168.1.150. you have to set the router to:

    192.168.1.150, 6100 (remote Client)

    192.168.1.150, 80 ( web Browser)

    Works great. Best 4 Channel I've seen so far in that price range. Still put them in all the time for smaller jobs.

    I actually called Intellicam to try the demo of the above DVR (the web server version), and the playback was actually really great. The user interface could be better, but the recording quality and the way it synced to the audio. They have a Star Wars movie playing on one of the channels, and I was playing back some material from that one. H.264 is very impressive.

     

    Will get an 8 channel to try for our next job.

     

    PS. You can run the DVR with a remote client also so you can pull video streams from diferent locations also.

    Sure that one is great also.

     

    Wanted a model that has a 4, 8 and 16 version though. Intellicam usally has really good prices for maybe not so brilliant stuff, but I was thinking maybe they actually found something good in Korea for a change.

     

    Like to get some opinions though.

    Has anyone tried it? Besides the fact that it is Intellicam how sells them, the specs are pretty interesting. Obiously the h.264 is the key here, together with full audio,720 X 240 rec varible bit rate, low res version for streaming.

     

    Opinions?

    Scroll down to see a remote PC shot. Think the interface looks like a modification on the Argus DVR interface

    Data, Don't worry about this character, I'll have his name and IP blocked tonight.

     

    I'll love it!

    Intellicam the OEM. That's actually pretty funny. There DVMR / Argus DVR's are pretty crappy, but they do have another DVR made by Argus that is coming out soon in 4,8 and 16, JPEG-2000 and dynamic IP support. I'll probably will try one of those while I wait for the Intellix/Lexion DVR. Talking about the cheap systems.

    The "reddier" the led's, the lower the nm values. above 1050 or so, you can't seem them, but most chepo cameras can't "see" the higher led values. Look for cameras with high nm values, but you would probably not find them in cheaper IR bullet cameras.

    Thanks guys for all the help!

    I am going over there at the end of the week to try some of the ideas.

    Couple of things:

    1. If I plug in a cable at the loop out from the DVR and let it hang loose, I get a very whited out picture, and if I then unplug it from the loop out, the picture goes back to normal. That would I asume mean that when nothing is plugged in to the loop out, the auto termination works, and as soon as I plug something in the termination turns of.

    Right track or?

     

    2. Since the cameras work great if I plug them all in to the DVR's and skip the multiplexor, could it really be a power supply/wire issue. Problem is that we only replaced the cameras so re running wires would be a real head ache.

     

    The DVR is from HUNT

    I'll try changing the multiplexor first.

    Chepo multiplexor ($300) and great DVR's ($2000).

    Fred,

     

    Since you installed 26 high end cameras and a good power supply and 2 DVRs, can you explain why you are using a mux?? Is it for "call up" purposes??

     

    If I am reading your components correctly and all the cameras are 24vac, then chances are very good that your mux could be the problem...

     

    You also stated that you changed some cables around, what type of cables are you using? Is it a coax or CAT5E?? I have seen a similar problem with one of our installations, where set of 8 cameras were giving us a problems, even after we changed the cables.. What turned up was that a set of cables were run very close to main electrical power distribution of the store, thus introduced the 60HZ into the cable. The simple fix was to move these cables few feet away and the problem went away... Double check your cable runs to insure that they are not very near to electrical panels or tie wrapt to electrical conduits...

    They wanted to have 3 monitors with 9 cameras on each, and I diden't want to spend the extra money on a 3:rd DVR. All cabeling is done with siemese cable (contractors wire and cable brand) I have a 4 channel dvr that I am going to swap out the mux for, just to try it. Since the signal is fine if it just goes to the DVR, the mux might just be the problem. What do you think

  17. Posted

    All 24 V color cameras, with a Altronic $225 16 channel power supply, individually regulated channels, top of the line power supply.

     

    Some odd ball brand mux. Might be the problem. Might take it out and put something else in instead. I think i will call Altronix tomorrow and ask them. Really knowledgeable people there. Linking like that has never been a problem before.

     

    Is there a meter of some sort to check for ground problems/ signal streight?

  18. Posted

    Tried with 75 Ohm terminators. No Difference. All high end cameras, and also different ones. (GE, Samsung SDN -520,)

    It almost got to be either a "weak" signal. or some sort of ground problem since he cameras look fine when I run them directly to the DVR.

     

    The Multiplexor is some of brand, but they do show up fine on the multiplex monitor.

     

    What else could it be?

  22. Posted

    Have a setup w/ 26 cameras, 2 16 channel Hunt DVR's and 1 multiplexor.

    3 monitors. 1 screen per device. Channel 1-9 on the 2 dvrs driving 2 of he monitors. Channel 10-13,14 on the dvr's looped out from the dvr's in to the multiplexor's channel 1-9 to be viewded on the third monitor. The point of the setup is to only use 2 16 channel dvr's and see 9 cameras each on 3 monitors.

     

    The cameras that are linked to the multiplexor shows up fine, put when I switch the dvr views to 16 channels I get flickering on those cameras that are linked. The interesting thing is that when the signal continous to the multiplexor it shows up fine. If I dissconnect the loop-through cable to the multiplexor the signal at the "dvr monitor" shows up fine.

     

    Any thoughts?

     

    Was thinking a couple of things:

    1. Get an cable amplifier like this on http://www2.cop-usa.com/ebproductdetail.asp?id=546

     

    2. get some kind of isolator or something.

     

    Tried to run the cables first to the multiplexor and then to the DVR. No difference.

    It is not happening to all the cameras that run to the multiplexor, but I can see a slight picture deration on all of them.

     

    Any thoughts would be very welcome!

    Did soe research about the subject and it seems the matrix system is the way to go, specially if you have mutiple monitors. Wondering though have the DVR would interface with the system? Like a multiplexor type way so it would only record every 24 frame in a 24 camera system for example or...?

     

    Individullay isolated channels on a power supply or...?

    We just finished a 26 camera job, replacing all old cameras with new ones, and adding a few more. Put in 2 16 Channel HUNT DVR's. Have a few problems , with scrolling lines. Haven't really tried to fix it yet, but would could be the problem?

     

    Never really had to worry about that before, because all our systems have been up to 16 cameras, and have not had any problems.

     

    Bidding on a job with 64 cameras tommorow (replacing 4 16 channel multiplexors and the cameras in a hotel).

     

    Couple of questions on these bigger jobs and how to approch them:

     

    1. 12 or 24 Volts? Thats the least suceptible to ground problems etc? What other benifits are there?

     

    2. Individually isolated power supplies?

    http://altronix.com/index.php?pid=2&model_num=ALTV2416I

    Does it make a difference when it comes to ground loops/ problems etc.

    On these big jobs I would much rather spend $100 extra to get a great power supply if it means less chance of a headache.

     

    3. What is the best way to control so many cameras without spending a zillion dollars on a pelco matrix system, or a Dedicated Micro system? Need 4 good DVR's that you can control all the functions from a camera controler. Nuvico is coming out with one, but it is a few months out.

     

    Suggestions please!!!
