Here is another Blue: now please take into consideration I am not a graphic artist so they might not be as good as they could be and some kind of grey mishap

the black, or charcoal/grey is the default design but with the buttons etc moved, added, or changed. the others are ones Im playing with right now, have some minor adjustments in the INI files to do right now. No, wont work with that DVR, this is for Dahua DVRs only, not sure if that DVR's software has any skin files or not.

no, it isnt a Dahua.

Looking at their non IR and IR ones for a job ... cant find any good samples though. Several other TDN Bullets I tested over the past year have basically been junk, especially compared to TDN Bullets from a few years ago. Need something that works good, good day image and not a ton of noise at night like all the rest.

Goto google earth and screen shot the area, use image editing software to mark out camera locations. Use the distance google shows to approximate your camera distances. Power far cameras locally, install a large weatherproof box if need be with an AVR. If there is another building you can power them there, optionally put a separate DVR/NVR in there and as already mentioned maybe monitor it all over the internet/network. This possibly sounds like a job for cat5/UTP transmission. If you want someone to design it just send your diagram with the distances and camera locations to a manufacturer like NVT and they will tell you which of their products to use.

Make sure the lens is as close to the front cover as it can be without the actual lens glass touching. Make sure if it uses a rubber ring and not a separate compartment for the IR that the ring is tight up against the glass. Its possible it IS tight against the glass and the camera is as far forward as it can go, but you might just have to zoom it in a little more. BTW, the camera looks like a Color IR camera, not a TDN with IR cutfilter, hence the washed out colors in the day.

But you're running multiple cameras on the one 25-pair UTP cable?

Yeah run the cable in conduit. Otherwise have the Video Loss send an email alert.

Could use something like the Dahua DVR and then start with budget cameras, always can switch out the cameras later for better ones for certain locations. The wiring may likely take up alot of your cost though.

This has already been discussed in hundreds of threads here so I will refer to one of those and call it a day. Eg. viewtopic.php?f=17&t=23278

Yeah thats me ... the last one i built was it, still have a few clients with them but trying to get them to switch.

?? Well one can use CatTV cable too if they have it lying around and then its free, cant get any cheaper than that ... but most of us know better than that. Look, with cat5 you have to change the signal, those baluns arent just a connector, the final image on the other end of the cable will depend on what the balun does, not what you see at the camera - why should i put the quality of my video on the other end of the cable in the hands of the balun manufacturers, if I dont have to? With coax you dont even need a connector. Im not saying dont use cat5, there are certainly cases where one can benefit greatly using cat5 over coax, just saying realize there ARE differences, kind of like what wifi is to hardwired networks.

when the area where the IR is, is separated from the area where the lens is, by not just a piece of rubber.

Right, edited to read Guarenteed instead. " title="Applause" />

need to have the camera right up against the glass so you dont see any reflection. Maybe put some kind of black rubber or foam around it and tape that to the window?

Your best bet when it comes to domes and bullets with IR is to get one with a separate compartment for the IR. The rubber ring thing works but then doesnt always, especially if you took the cover off to refocus. Many IR Bullets these days will have it separated (except for the really cheap ones), when it comes to domes you need to look for Turret IR Domes, they have really cheap versions of those also. Even then IR domes never seem to have the IR distance that IR Bullets do, averaging 20-30', with bullets anything from 20'-30' for real cheap ones to 60'-70' for the typical TDN and then 100'+ for ones with 5-50mm lenses. None of them can match the IR of much more expensive and large cameras such as the Bosch Extreme products which literally blast the area with IR, or using separate powerful IR.

Thanks guess I missed that part I had emailed Altronix but no reply yet. Also looking at a passive device from Muxlabs. Passive should be okay for 600' right?

thats the zoom camera, most zoom/ptz are 1/4"

doesnt apply in this case as their power output from the device goes into unknown wires on the cat5 cable, its some all in one thing. So if it only uses 1 pair, then we need to know that to be able to use the calculator, but we dont know how many pairs it uses.

Thats just a generic calculator.

Better quality, better everything, always will be, its for that type of signal, cat5 baluns etc are just work arounds or hacks. If you can save considerable money using cat5 then do so, otherwise stick with what is guaranteed.

Coax is the standard for CCTV, so it is always going to be the best, although sometimes, especially larger jobs, cat5 can make things easier.

Yeah im looking at the SCO-2080 without IR as its for a fully lit car park and its going to be generally wide shots or at least no more zoomed in than 10mm. And then the one you have for the gates to zoom in on them. I never use cat5 but looking at a couple options for that for this job also, maybe the Muxlabs 16 channel passive transceiver which is kind of cheap, and then separate baluns for all the cameras and can use active ones on the longest 500-600' ones if need be, though they claim passive can do 2200'. LOL. Reason for the cat5 is we can just run one large multipair down the car park and split off from that to each camera. Coax will take maybe 6-10 1000' rolls! Altronix also have an interesting Active unit with 1A power per channel and also data, though thinking it might not be worth it if I cant use its power over cat5 if I cant run the power more than 350' - waiting to hear back from them on that. Another thing I need to look at is the Samsung Portable controller, so would need cat5 connected to each camera for that, though it also works over coax. Might get that as a tool though, add it into the total cost. You should get one so dont have to keep going back and forth to the camera http://www.samsungcctvusa.com/products/ProductDetail.aspx?ProductID=314 The client said to keep the quote low though so ... probably wont even get it ... either the wiring or the cat5 video transmission alone makes it high even with the cheapest cameras.

Ok my only question about the zoom is this, maybe you can let me know if you noticed this with these. Ive used some older (few years) samsung box zoom cameras, actually they were preinstalled at a gas station looking at pumps by someone else, but everytime car lights hit them they adjust the focus essentially going blurry until the car lights go away. Seen anything like that with these?

CNB looks so much beter on the Dahua DVRs though But yeah im passing them by from now on other than indoor applications. Also quick question, did you or would you get a chance to test that camera with car headlights? Im considering it for 2 entrance gates, it has that highlight compensation and might be good enough for headlights and cars. My choice is a bunch of the bullets, the SCO-2080 and 2 of the SCO-2370, or box cameras and housings which would be alot more work, and money. Granted I need a gang box for each camera, its still less work than messing with separate lenses and housings.
