  1. You can wire the loads parallel in the PS and you double the limit of the PTCs as they each see half the load. Do it, I do all the time. I almost exclusively use 24VAC and have to step down for bullets and such all the time. Usually those trasformers are rated at 1 amp, thats good enough for 3-4 bullets if you wanted or 1 decent IR.

    Small, low cost LCD monitors?

    I think you have a pretty good grasp on this, the only thing I can add is you might look at Xenarc's offerings too. Sometimes I install these small LCD above doors where the camera is on the other side. Way better then a peep hole.

    DVR alarm

    Use their feet on the floor, you'll have to premeasure and mark. You can use postit notes and then configure the DVR for the action you want taken. You may need to use a loop out to get it to process the feed totally different on another channel if you want to use the camera for normal MD recording too.

    DVR alarm

    Depends on the DVR and it's config. It's not an uncommon feature on PC based systems but you must have a sound card and speakers plus the drivers installed. Geovision specifically makes this easy.

    Aiming IR Illuminators

    The goggles do exist but you have to have one hell of an illuminator to compete with the IR of the sun. I think your better bet would be an IR pass filter on a cheap BW. You put the camera where you want the IR and then watch the feed while adjusting. When pointed staight on you should be able to see individual LEDs. Never tried it but I have played with IR in a simular way, you can kinda tell when they are pointed directly at each other.
  6. I do it backwards, active transmit and passive recieve. My logic is getting the signal to the DVR won't amplify issue picked up along the way. Like I said though, very rare for me to use Cat5.

    GV-650 Password Reset

    Since it's pretty useless right now any chance of bringing it home? How in the hell did this happen in a super secure area? I guess I'm probably not the only one asking that. Call the dealer that installed it, they should be able to do this and are obviously preapproved.
  8. Never done it but all powerline controls have some hidden troubles. These devices usually work on 110v current, well you have 2 legs of 110 in an install like that. If the router is on one leg so must the camera, not to mention going through transformers between the houses and a gaurd shack. I know it will work just not something I would bet an install on, not when wifi is an option.

    uPNP on ver8

    Hard code them in there. I kill uPNP on all my networks, I don't like software being able to open ports automagically. It's okay for the windows firewall and all but I manually configure the hardware firewall.
  10. Never done any real testing as I avoid Cat5 and baluns with the expection of a few circumstances. As such I never ran coax next to it to find out. You can run 4 video feeds through Cat5. You can run 2 video and power for 2 bullets/boxes up Cat5, very low power those wires are tiny. I ALWAYS run 18-2 with the Cat5 just for power. I don't use Cat5 unless the run is more then 250' feet, usually longer. I might use Cat5 where you have a cluster of cameras in the same area. I'll run the Cat5 into the area and coax>cam from it x4. Example large retail warehouse... Cat5 to the front door area, 4 cams there covering the entrances and exists from both inside and outside. Cat5 all the way to the back at the loading dock, 1 cam inside the dock, one outside the foot door, and another looking from the outside at the dock. Coax to 4 PTZs up the middle of the building, Cat5 for the RS485 data. Coax for everthing else. Cat5 is nice for building to building like in schools, 1 Cat5 to each building and you can hang 4 cams off that building. Whenever you do building>building USE LOCAL POWER!!! The buildings will have a difference in grounding and you will see that in your video.

    GV-650 Password Reset

    Do you have control center services installed? Is there any remote access to the box? We dont really like openly saying how to bypass Geo's security, it's not good for the product in the long run...

    gv250 and video authentication

    Not as long as it's taking place indoors... Not much different from Ken's modified DNS example. If someone is knowledgable enough just about anything can be faked/bypassed. Sidenote on Ken's DNS example! I actually did this and it worked PERFECTLY. When I proposed to my wife I rerouted a page from Geocaching.com to my local apache server. It was classic I couldn't believe she bought into it. Sure enough she did, we found the bogus cache and in it the engaugment ring. I was not going to be leaving the ring in a real "live" cache, this worked perfectly.

    questions regarding purchasing dvr from newbie

    Depends on some things, you obviously can't have the best of everything but $2K is getting pretty tight. If you bought 4 a month every month might be a different story. Reducing your framerate would help a bunch, 120fps still gets you 9, not half bad. I know I build some pretty sweet ones in that range. Gets you a GV800-16 on rock solid hardware and a highly modified XP Pro install (basically becomes single use. DVR.) What cameras are you using? The best of the best will suck with bad cams.

    Low cost 'Quad' processor off e-bay

    1. I don't get many requests for quads so take mine with a grain of salt... I have heard Everplex has a some decent low cost quads. 2. Most DVRs that I have dealt with (PC based) don't natively come with quad output. For Geovision specifically a quad output is a several hundred dollar option. I don't even think Avermedia has a quad output option but I'm not sure. I would definately keep going on the route you are on, if you need a quad output just look at quads. What kind of display? I think this will probably be the killer, if you use nice displays they can show off the flaws in quads/cameras/everything. This really shouldn't be the case anymore, with a quad that had a component video out you should have a 1:1 pixel map on 4 640*480 feeds displayed on a 1280*960 HD display. This would really be pretty sweet but I haven't seen a quad that has that kinda output.

    Probably so, you also might not be able to fully nest tags like IMG. I really haven't a clue but it appears you are going now. So have fun and learn much.
  16. HDMI = DVI digital video and SPDIF audio in one cable. It's not very common in pro grade equipment, it's really a consumer interconnect right now. I'm gussing this thing can also matrix audio as thats the only reason to go HDMI over DVI alone. DVI-I is much more common as it carries the DVI digital as well as the analog VGA so you can go either way at the screen.

    has anyone tried this.............

    That would make my suggestion a very bad idea, I was kidding in case nobody guessed that. Above when I said you can stand the temp indefinately, I meant you personally. So an attic in OK would be a no-go, aske me how I know. But 90*F you should be able to do just by pumping water around, it's less then ideal but cooler then the CPU and HDDs. Don't forget the HDDs!!! If you just waterblock the CPU the HDDs will fail if pushed. I wouldn't use the PC water cooling stuff much past the waterblocks. An automotive heater core smokes their radiators on bang:buck and you'll have no flow restriction from them as most are 3/4" throughput. You also get a huge variety of sizes. Don't use cheap fittings and hose, make sure everything is threaded and have custom hoses built at a hydraulics shop. They can probably modify the fittings too if needed. I once had 4 SS braided braklines made for my Jeep for something like ~$50, metric on one end and SAE the other. This is NOT going to a customer right?

    has anyone tried this.............

    If you can stand the temp indefinately the water/liquid cooling is a possible solution. Although a Peltier cooler can go below ambient it's pretty inefficient. Might put one on the raditator of a watercooled setup though. You could be really slick and watercool a rackmount to the top of your beer fridge and put the radiator in there. I don't know what the fridge would do having a couple hundred watts to chill.

    Linux Based Systems

    Knoppix can also be a handy tool, not just a kids toy. Gotta say thats another great use for it though. It's amazing how much they can fit on a live CD.

    Motion Detection

    It's just life with an IR bullet, bugs don't do that to plain cameras. Do you have a webbing spider population? Spiders love IR too I've had customers that had to clean theirs weekly.

    Core 2 Duo

    http://download.intel.com/design/chipsets/datashts/31305602.pdf page # 44 You need to look at the Southbridge and see which number it actually has, if it ends like the numbers I posted above reinstall Windows and load the matrix drivers. You might also look at the Tom's Hardware review of the ICH8 vs ICH7 too. I believe they did their RAID testing on a chipset with another different number ending, they specifically mention it is not the ICH8r that has more RAID functions. Windows is software RAID, if something happens to the Windows install your RAID array is probably borked. It's not too bad but performance is not it's high point, ease of setup is it's domain.

    Video Signal Analysis Tools

    I have never used anything related to the EWM40 or the RAPPORT337, which also I have no knowledge of relation to each other. Oh, it's a Wonwoo! (High end MCM) ......and expensive. Anyone know the price (US) for it and that EWM40? It says $549 at CEpro but I noticed MCM made the posting. I do think it's a cool product and maybe not more for same with the EWM40, I'm thinking the EWM40 will be quite a bit more. They are two completely different products. Yeah I know, I am now further considering purchasing the EWM40. The previous statement does kinda make it sound like the two were related.

    That is the Repport337 posted above, looks cool huh. I am liking that EWM40, before it was the RAPPORT337 but the EWM40 seems like more for about the same.

    12VDC/24VAC choices

    24VAC is superior all the way around. You can also use a setupdown to make any 24VAC power supply 12VDC, these are pretty cheap too.
