Not really worthwhile, but direct TV is a simple BNC>RCA adapter.

Plasma typically 0wns LCD starting about 50". Plasmas don't have the responce time issues of LCD, especially noticable at these larger screen sizes. I would only look at displays you can demo from a laptop. Video is not nearly as good of an indicator of clarity. A word document in 4pt font tells you alot. It's going to be hard to find a 42" 4:3 display, your customer will probably be pissed with columns or streching. I would be anyway, the 4:3 columns to 16:9 take up a significant portion of the display. Think 27" 4:3 would be about the same size image. For the guys home I would get a true 1:1 1920x1080 display, then he can matrix or multiview at 1024x768 and still have display for other home stuff, stock/sports tickers, encoded TV is always nice too (640x480) which could fit beside the matrix.

Here is an image you might find helpful. << It shows a single matrix of 9 @ 1024x768, the only option I have found. As you can see I set my display resolution to 1280x1024 so you could see everything at once. That little toolbar is what you get when you load Control Center. It really hasn't taken me too long to get it though, you can do the host database like multiview, you can then group hosts, you can matrix either hosts or groups It also gives you an idea of the control center configuration, 5 tabs pretty basic. It also shows you the matrix config screens specifically.

I have it, it's alot better for maintenence then remote viewing. It does have a Matrix option that I have just started looking into because of this thread. I wasn't overly impressed initially and I suggest you use a 4:3 display if thats what you want it for, it supports 4 1024x768 displays. I'm thinking it might be better to use 4 20" LCDs at 1024x768 the one 42". I'll keep playing with it, it works well though for customer support. It has it's own RDP system so you can RDP into systems even if they use XP Home. It has a remote DVR function as well which basically gives you the local Geo interface. Playing with the Matrix again makes me more firm in thinking 1024x768 only. I wouldn't look at widescreen displays unless you want excess desktop shown or a streched image. Unless that is you can find somebody who can make the matrixes sizes other then 1024x768. By FAR I use this more for service maintenance, the remote DVR locks up over time though. It's not quite as stable as MS RDP but it does allow you to monkey anything on the system you need to. EDIT: Yeah I further push for multiple monitors if you want multiple matrixes. Why would you though? Each matrix supports 64 channels.

You also need to install a filter between the RJ31x and the alarm control. They make filters specifically for this. I have no idea how they work though.

Zooms acting like varifocals...

I have had to use shims before. -
Yes it's is a refresh rate thing, not too much you can do about it that I know of. Progressive scanning camera maybe. You might be able to speed up the refresh rates of the monitors but I doubt enough.
-
Yes it makes a difference, the 50ohm are usually used in audio.

Own a Geovision card? Do yourself a favor, check out Livevue
CollinR replied to RichTJ99's topic in Geovision
Love the sequencer! Maybe an option for switching in fullscreen (no menus) mode, less burn in... Does the sequencer not work for you guys in MultiView v8.1? Or what does the video polling do? -
You might try pulling the lens out and makeing sure there isn't crap on it. Water spots and such can cause things like this.
-
Alot of people like their surround sound and the possiblity of HDTV, therefore they won't have a coax connection from the cable box to the TV. Otherwise I guess it's cool, they didn't really explain the modulator injection part though.

Need help choosing the right cameras
CollinR replied to mpratt's topic in General Digital Discussion
I gotta disagree, I just had a real world example of how well all electronic security works. S. OK had a severe ice storm, broke 400+ poles and killed all 5 of it's feeders into the city I live. Up to about day 3-4 all was well, cold and dark but okay. Day 5 all residential alarms have failed, most commercial ones as well. By day 6 was almost martial law, public cerfews and such. (POTS and even my DSL worked and is why I was abled to post, from generator power. AT&T really came through.) When you see video of someone during a crime where they obviously know the video will survive, you have seen a small percentage of criminal often drugs/alcahol involved as well. Far more people will convert to criminal mode when they know with reasonable certainty that there is no video and most likely no alarm. This too is an example of their real effectiveness, add in Katrina and most other national disasters. Some were stealing food and water... some were stealing plasmas... -
Do you have an alarm? The proper way to do this is back at your telco distribution, run line 1 to your DSL filter/splitter, put your modem on the non filtered side and then go back in where line 1 was before with the filtered side.

Need Suggestion on DVI Extension
CollinR replied to Ghazi's topic in Installation Help and Accessories
It's $20, try it. I would think the worst that could happen is it not work, I also think those are straight through cables too. I mean they have 15 pin HD15 adapters that do nada but change the plug. Heck it wouldn't suprise me if you couldn't put one of those DVI>VGA adapters on the card and use a non-DVI pigtail. Never tried it but I never saw the benfit of using a DVI board anyway. -
You probably installed a PTZ with duplex serial communications so it could communicate it's current position, angle, zoom... back to the controller.

is possible to have internet acces in 2 systems?
CollinR replied to alterelectronica's topic in Geovision
You are going to need to get the user manual for your router and see what it can do in forwarding. I assume since you already have one box going you have a basic setup to copy, just add 1 to the outside ports and point them to the second DVR's static IP. Then when you connect to it you just need to add 1 to the ports to connect to the second box. http://yourdomain.net If you don't specify a port web browsers will default to port 80. http://yourdomain.net:80 http://yourdomain.net:81 Same goes for every other client connection method, even RDP if you have XPpro. -

CollinR replied to alterelectronica's topic in Geovision
Yes, you will have to use port forwarding more advanced though. If your ports are 80 and 3550 You can make DVR1 80 and 3550 straight through the router Make DVR2 81 and 3551 in the router forwarded to 80 and 3550 internally to the second IP address. You will only need 1 dynamic domain name but you could set one up on port 81 if you wanted. -
You are probably going to have to do cam>PC>display. In the CCTV world megapixel fits the bill, IP only so Cam>Ethernet>PC>Display. Firewire could also be used but not nearly as common but is on some HD TVs. This also depends on the display, with HDCP now you are basically limited to HDMI. Since analog signals can't carry HDCP data most HDTVs will scale the video to 480p if the connection is made via component, 4:3 aspect ratios on VGA often limted to 1024x768 or something like 1366x768. Also there is only a fistful of displays that can 1:1 1920x1080 (1080p) most scale it down to something like 1366x768 (~720p). So make sure it's not a worthless endevor of 1080 for really only 720p displayed.

The last 9 days I have been on generator power stuck in the southern Oklahoma ice storm. McAlester, OK looks like a bomb hit it, every tree is damaged.

I think your expectations are reasonable, I know I sell a very nice color 24hr vandal dome for about $400 that has picture quality second to few. If BW bullets are acceptable I sell a high resolution off brand unit with good low light performance for about $120. HTH and PM me as much info about your install as possible if you want a design.

Need camera suggestions (with environment/requirements)
CollinR replied to rojhan's topic in Security Cameras
Would you happen to have any video of someone walking onto your porch at night? I have a feeling you'll have some difficulty identifing them, you can tell from that picture that the mailbox roughly twice the distance a person would be is washed out to the point you can't see the door seam on the right side. I'm thinking a face at half that distance would be basically a white oval, maybe see eyebrows. In BW and $150 it could be alot better, so much so thats why we are saying what we are. Those cameras work okay indoors in large rooms for overviews. If you get very close to the camera at all it's IR washes out the picture. For a little more you can have a remote IR emitter that doesn't bounce the light right back into the camera. Also the IR doesn't last as long as the camera so it's nice for them to be easy to replace. My customers often choose to go elsewhere the first time, I used to have a jingle about when the Ebay junk doesn't cut it anymore. I do as many retrofits as installs due to this. It also depends on the goal too, CCTV as a deterent, observation, evidence capture, specific evidence needs, identification, recognition. In order of difficulty and basically price too. -

Hell if you consider MACE just buy it from alibaba and take the middle man out. One of the things to consider too kg6mti is we see lots and lots of cameras. Your system may still be making you happy after 3 years of service but we look at many aspects before we sell a product. I can sell MACE stuff I just don't. -
I thought he just needed a chassis. lol ITX? MATX? ATX? EATX?

They claim it is but it's on some BS Chinese website so who knows!

Will i save a lot of HDD if I use 640x480 instead 720x480?
CollinR replied to osity's topic in Security Cameras
I have had nothing but bad with H.264 too... Several manufacturers, CCTV and home theaters (much more quality critical!!!). It all comes down to how much bitrate, most people want H.264 for the smaller filesize and thats it.
