That could get quite annoying though. As video motion from a CCTV system could be going off every few seconds depending on the system, location, weather, time of day etc. And if they are trying to watch TV .. well

I have no issues with that. Fit RG59 (siamese) in a 1/2" crack between 2 beams above a camera today, joining the camera connections. Had to bend it almost completely to fit it snug and works like a champ - in fact we have it run between the cracks of the iron beams where they meet the ceiling, cant even see it. It can be heavy to pull especially when dealing with dozens of wires, but at least its strong cable - cat5 just seems so flimsy. IMO cat5 or better yet UTP multipair is best suited for multiple building apps and long runs.

4 channels each is simple. if you are watching cameras in a 64 way view it doesnt have to be in D1, can just be low res, then you can adjust individual cameras to D1 when needed. Or run a single viewer for the D1 only when you need it.

Do you know how much current they supply and to what distance? Eg. if using 12VDC 550ma cameras.

toggle bolts? optionally with piece of 2x4 on the inside?

on slow connections here we connect using low res. So 16 in low res is okay even with 384-512 upload speed.

This is software from a Chinese company that works with various IP cameras and DVRs. You then connect to this server instead of the IP cameras or DVRs. http://www.linovision.com/en/featuredsoftware/nvr.html

Im primarily a developer not just an end user, so Im comfortable working with anything someone throws my way - however, I have not used any central station software like that. Most just stream the video for themselves, and clients connect direct to the DVRs separately (I also do work for alarm central stations here, and have assisted the alarm central station software programmers in the past). That said, far be it for me to mention something I have briefly tested before, but here goes, you could look into a program called DSS from Dahua, its enterprise software for their DVRs. Client connects to the DSS server instead of the DVR - though I am not sure if it still streams from the DVR or not, as I didnt test it extensively due to time constraints.

dumped them a while ago, seems they have gone MIA. Doubtful if there is any mobile app as wasnt much smart phones back then.

So I guess I shouldnt be chasing them down the beach with a machete??

Normally no, but depends on the DVR manufacturer. Most DVRs can be totally different from one another. Writing code for everything out there is like pulling teeth, and thats after you get past the language barriers. Some may work with VLC though, then you could restream that out. The DVR would need to support RTSP though, and VLC needs to run all the time for you to connect.

In this case its branded by XTS Video out of Florida. Its the same unit though that others brand under different names. Example, the QVis Apollo HD. I get the QVis cheaper than the XTS so i now use those But the actual model from the manufacturer is the LE-A. We can normally tell what is what by the specs alone.

Agreed. What are you recording them with and are those pics from a "live" shot or from "tape"? thats playback, recorded on a Dahua LE-A DVR.

BTW if its a small office, even a cheap 420TVL Color IR dome would light it up good. I just installed one in a 15x15 office and it works great.

As mentioned the 2.8-12mm Eyeball (Turret style) IR domes, 600/700TVL, run around $100 retail. They are fairly short range IR but are the step up from the cheap Color IR domes. Either way indoors it should light it up good. Otherwise check something like the CNB VBM-24VF for a non IR low light camera in that price range, might be $10-20 more than your budget though.

UFLED30-9BD is 940nm and should do it also. Not cheap though. Also google Axton AT-7B-74830, made in the USA? And check out CNB's IR. Eg. CNB MIR1000 or CNB MIR3000

Bosch UFLED30-8BD

They shouldnt be using 22/4 to power IR cameras.

Really?? Okay then

Does it only talk about IP video?

We got by just fine before IR corrected lenses came about. Its all about knowledge and experience Ok that might not have come across the right way. What I meant was, there is a way to focus without IR Corrected lens that gives you a great day image and night image. There is however then an inbetween that can be slightly off by about a few % (eg, overcast in the day, etc), however no more than I have experienced with the VBM or VCM 24VF cameras - which claim to have IR corrected lenses.

oops brain slip. Used to have vcm24f, still have bbm24f which needs a lens... Yet they still need separate focusing under IR for optimum IR focus. Seems they use a very cheap IR corrected lens if that. Just saying, from experience with using them, with IR. But then what does one expect at such a great price tag.

I'd love to see a night image.

Seriously Ive been using IR cameras for over a decade, and I thought this sucker was broken! have to go right up to it to only see a very VERY faint glow. I didnt even think to check the specs for whether it was 830 or 940nm prior to purchase .. In my case I didnt need IR at all, but impressed it worked so well either way. Sure its no Bosch Extreme camera, or Panasonic with Raytek .. But for the price compared to others I have used/tested .. works well. After all a TDN is just doing the job of 2 cameras anyway. If you want the best, get 2 separate cameras
