Anyone have experience with the new Eco series from DM? Interested in hearing how well it works and also if there are any demo sites to try out.

Thanks Rory. I'm passing along the information to my customer. It might be exactly what he needs. Tough to find IR sensitive cameras anymore in a low price range.

You have a difficult if not impossible task ahead of you, but give Richardson Electronics a try since they have carried that system a long time ago and maybe someone will have an old manual around. Here is a link for them. Good luck. 73 http://www.cctvnet.com/houston.asp

I've been told that the Vitek DVR will work with SBC dynamic IP. I got this information from a guy at VSSI. You might want to verify it with him. His name is Arshak and his email is arshak@vsscctv.com. The DVRs are the new DVR4000 series. He is their network specialist.

The best one on the market is still the old standby Telexper system. They were originally designed to be the most efficient DVR using POTS. Hardly any DVRs these days are good with POTS since they aren't designed to utilize the narrow bandwidth allowed. You can still get the Telexper's although they aren't cheap. http://www.telexper.com/

Adding to the previous post, if you want to use covert IR then you should use a camera designed for IR use such as the Extreme CCTV line of cameras. http://www.extremecctv.com/home.cfm

So if a router is used that supports NO IP or another similar service then any DVR could be used with dynamic IP? This would open up even the really low cost DVRs like the Argus and Everfocus to be used with dynamic IP and would pretty much eradicate the need for the DVR company to make it's product dynamic compatible. Am I right in thinking this?

You can have IR illuminators with no red glow but they have to be in the 940 nm range and that severely limits the distance you can see. Most people don't mind a dull red glow and would rather have that and extra distance. Only in the most covert operations would you need to have no visible light.

How can you use no ip with an embedded system? In what way could you load the program into the DVR when the entire OS and DVR program are on a chip? Is there some other way to allow use of no ip maybe with a particular router?

Almost always use an auto iris lens outdoors. First they aren't much more than manual iris lenses and second you will get maximum opening at night when you need the most sensitivity and it will close down during sunny days so the camera won't get overloaded. Auto iris lenses come with tiny lock down screws on the focus ring and also on the zoom ring if using a varifocal. One thing to remember is to focus your camera at night or by using neutral density filters so that you fool the lens into opening all the way. Otherwise you will have problems with blurry focus at night.

Go to your local distributor and borrow a ground loop isolation transformer. Vicon and Pelco make them. That is the easiest way to check if you have a ground loop.

I'd go with Pelco. They have the best housings and you can order them with a demister option which is different than a heater or wiper. Quality stuff. If you just want a low cost housing with heater and blower then the Vitek is ok. Here are a couple of links. ftp://www.pelco.com/SelectionGuides/21030.pdf http://www.vitekcctv.com/Sections.asp?SectionID=1009#20

You are correct in saying that your resolution is cut down to 1/4 res when viewed in quad compression. Still it should afford a good enough picture to see what is going on. Plus there are several quads that will post real time viewing in the quad mode.

VSSI bought a whole bunch of them and now they are blowing them out close to cost so I don't think they liked them very much. That's about the only thing I've heard about them so far.

The quad that you have most likely has an expansion on playback ability and that is why you have a vcr in and vcr out connector as well as a monitor connector. The hookup should be the 4 cameras to the quad and then the vcr out connector on the quad goes to the vcr in connector on the vcr. That leaves the vcr in connector on the quad that hooks up to the vcr's vcr out connector. Hope that isn't too confusing. Then the monitor connector goes to the first monitor. On the first monitor you will see a video in and video out plug set. The monitor out on the quad goes to the video in on the first monitor. Then you take another cable from the video out on the first monitor and run it to the second monitor's video in. Depending on the monitor you should also see a slide switch that has 75 on one side and an ohm sign on the other. The first monitor has to be in the loop through position so the switch has to be set opposite to the 75. The second monitor is the terminating monitor so that switch should be set at 75. Simple isn't it? Here is a link to a quad manual that might help. Page 7 has a wiring diagram. Even though it may not be the same quad it has similar wiring.

It depends on the DVR. Most embedded DVRs use composite video monitors which can be a CCTV monitor or a TV with a video input. PC based DVRs almost universally use computer monitors.

Depending on the DVR you should be able to control the PTZ directly through the DVR remote software. Have you already purchased the domes? Maybe some more information on the DVR would be of some help.

Let some of your other Nigerian CCTV dealers know about the web site. It isn't advertised so most everyone discovers it by word of mouth. There are several countries represented here. It is growing every day.

You'll need this converter to go from BNC to RCA, you can get them at Radio Shack if you don't already have one. As VST said you have to plug it into the video jack on your TV and then choose the video view option usually on the remote. It should work ok. http://www.vitekcctv.com/ProductDetails.asp?ProductID=135

Checkout this site. It is a good end users site and has pretty much everything you will need. www.supercircuits.com

Except when they are running from all the crazed criminals you keep telling us about, or the odd hurricane that flattens everything.

I meant they don't get into other areas like vacuum cleaners, card access, alarms, home theater, etc. They have a couple of alarms, etc but nothing like an ADI or Tri-Ed or Richardson. 80% of their business is in CCTV. They have a huge inventory considering they only have two locations. Getting back to the original question I wonder if the guy found his plugs and wiring diagrams.

That is why SoCal is the laid back capital of the world. Comes surf time and you can't find any contractors unless you are at the beach. The phrase "Chill Out" doesn't always refer to cold weather around here.

Wow, that's a whole course in CCTV but here is a short answer. DVR records to hard drives and could be a quad dvr, multiplexed dvr, or multi channel DVR. Multiplexer is essentially a time base corrected high speed switcher that lays down video frames one right after the other in quick succession and then on playback picks those frames back out. Quad compresses 4 cameras into one video output. Switcher simply switches from one camera to another automatically at preset intervals. Which to use depends entirely on what your job requires. DVRs are becoming the defacto device to use on most jobs these days.
