It really doesnt matter the TVL, just go by the total image pixels, eg. 811x508 for NTSC high res.

thats just a distributor, i think this might be the manufacturer, the models on the farnell site and others might be older models: http://www.panacom.com.tw/home.php?fn=Products-content_pasge&cno=17&no=15 If yours does not look like that or similar, post a picture and someone should be able to identify it.

Actually one should ignore the TVL and go by the Total Image Pixels, all camera specs will list that and if they dont, dont buy the camera. For example, a 600TVL camera has the same total image pixels (811x508 NTSC) as a 480TVL camera, which concludes todays lesson on marketing hype.

Can you post a night time image when you get a chance. Thanks.

You could make a custom 404 page and maybe just put a master list of everything there?

We are talking about CCTV Cameras, so no, not the capture resolution. Thanks for clarifying that.

There are still some issues with Geovision and 64 bit as you might find around the forum, they just come out with the 64 bit version. Most DVRs have only ever worked on 32 bit. Thats why I was asking what the old one was, 32 or 64 bit?

32 bit or 64 bit? Was the old system running Win7 or XP? Although some have used Win7 without any issues, personally I will use XP over Win7 for a DVR, until XP is no more or I go Linux

Edit; Total Image Pixels on a high res CCTV camera is 811x508, NTSC. Also, well a 1/3" Lens and a 1/3" CCD, remember some people put other format lenses on 1/3" cameras also

Since you mentioned POE you must have some good pocket change to spend? You would need a weatherproof IP Day Night IR camera for that, not cheap. (Axis) You can get the same in non IP for almost 5 times less. (CNB) And thats not even comparing it to a decent IR Megapixel. (Mobotix) Additionally, the lower the resolution the better it sees in low light. So first you need to decide what you can afford, or really want to see. Also regarding the FOV, most True Day Night IR Bullet cameras will have a 4-9mm lens, there are SOME that have a wider lens. You can also get one much wider such as 1.24mm with a fixed lens camera such as a Color IR (not True Day Night) but you have to remember 2 things: 1-The IR Beam is normally only ever 30 degrees, while a 4mm lens for example is twice that. 2-The much wider angle lenses such as 1.24-2.45mm will require some hack job to the housing as they will normally show up the edges since it is so wide. 3-Color IR cameras typically have washed out colors due to lack of an IR Cut Filter. Bottom line, make sure its a 1/3" lens, CCD, at least 811x508 total pixels, and you should be okay. Although ... well .. it will still depend.

Most Windows Software only allow you to Grow the partition, I dont use Windows 7 so cant say (I thought it only lets you grow the partition though). I use this: http://gparted.sourceforge.net/livecd.php Download and burn to a CD and boot to it, allows resizing down or up. Watch out for Windows 7 though, thats not a good OS for a DVR IMO. As for recording to 2 locations, not sure what options the Avermedia software gives you. But you could do Raid, or NAS. Can FTP images on motion perhaps. Also, a more expensive route, though maybe no more then a proper RAID setup, is have a second DVR, just loop in and out of one of them to the next. So the normal options would be NAS or RAID, NAS needs a fast network though (?), and I think it depends on the Avermedia software. Not to sure as Ive never needed to do any of that. There is something that always comes back to us when dealing with clients, keep it simple. Worried about them stealing the DVR, perhaps put in a dummy DVR that is easy to notice, lock the other one up good. Some DVRs also have a CMS type software that let you record remotely over the internet on motion detection or on demand, small video files lower quality, and images.

What type of backup do you mean? Just a backup when you need it, or do you mean recording to 2 places at the same time? When Im called to backup I just put it on my USB hard drive drive then burn it for them on my PC, or put it on jump drives as the Cops/lawyers want that sometimes for the courts instead of Optical disks. If its something like a murder then we leave it on the drive for the time being just incase, they dump it later on. I normally just create a folder on the c drive called My Videos and that is set as the default location for backing up video or saving images from the DVR software. They only backup when they need it, its always recording anyway. I dont know about Avermedia's backup though as I only used their DVR cards once. Or do you mean backing up the OS drive? Best way for that is do image it when the OS is first installed.

You did say "Anything I need to test", so not necessarily testing DVR cards and Drivers, but perhaps remote video as mentioned by the OP, basically anything software related. And its not that testing hardware and drivers in a virtual machine is a bad idea, just that it doesnt work

4 cams it should be real time, or at least look like it. How is the recording? Sounds like something else is going on. What OS is it? How does the Hard Drive sound? How does the system feel, fast or slow, does it ever hang like where the mouse does not move for a second? Take out the Video card and use onboard video if it exists. The video card does not effect recorded video, but it does need to support Direct Draw Overlay.

For XP the OS partition doesnt need to be more then 40GB, in fact it doesnt need to be more then 8GB (max,could be alot less, I have installed XP on 2TB SSDs, total OS size 400mb or less, not for DVR though) but taking into considering the user backing up video to that same partition on occasion, hence the 40GB size. I had one DVR setup with a 10GB HDD partition for a couple years without any issues, except they started to backup video to that partition and after a year or so, they had forgot to remove it, hence the drive got full - it did not effect the DVR recording though. All the systems I have in the field over the past few years are running the OS and video on the same drive, but seperate partitions. If one partition table goes, the other does not. If one drive fails, well same chance as all or any of them failing. If one wants the max amount of drives some towers can take, then one has to do it that way anyway. If one could afford it then better would be an 8GB Fast SSD(or higher) for OS and 2TB HDDs for video. However it is important to note SSDs have a limited life span.

The GV800 is max 120fps Live video so with more then 4 cameras it may be a little "choppy". with 16 cameras it WILL be "choppy". You could lower all or some of the cameras to CIF and that may help, but then that also effects the max recording size. If using 720x480, at least drop it down to 640x480.

Those are newer then my main PC .. you dont want to sell hey? Im mostly using my old 600mhz celeron netbook now ... for development. That way, when it runs on anything faster, it will be, much faster! For much of that, a Virtual PC might be better, quicker and alot easier. For the occasional test I use other PCs myself, but for every day, sometimes every hour testing, have to do it in a Virtual PC.

According to this the video/lan is being sent through the electric lines? What is used at each camera, from the electric socket to the camera? That is the difference, and a big one. One brownout and its all over, UPS at the NVR or DVR wont help it at all. Also, I would imagine anytime there is a brownout or dip in power, the network would go down temporarily? Unless I am missing something? I dont see anything on their website though.

Well if you have no power you can't power your cameras and NVR so I guess it doesn't matter No the diff with that is we use Voltage Regulators on the power before it goes out to the cameras and NVR, Is there a way to do it with this? Can you do that between the outlet and this for example before it hits the camera? Also, what happens to the video when the power dips? I guess once you can place a UPS between that and the power outlet it would be okay right? Seems like would need a single UPS Voltage Regulator at each camera at least?

Question regarding the powerline devices, how do they protect against brownouts and other power issues?

the Geovision app is not developed as a service. So doubtful it can work, properly. For example, for starters a service is something without a GUI. GeoVision, whether hacked to run as a service or other, is a control filled GUI which uses a ton of memory and CPU.

Wireless isnt 100% wireless though, still need power. Look at videocomms 900mhz stuff, supposedly penatrates through walls more then others, but limited to amount of cameras with that stuff. If it is an old house like we have many of down here, mine included, thick concrete walls full of steel .. may not have much luck getting through more then one wall if that. Want to make the wire run pretty (ish), perhaps some white cosmetic wire mold.

Yes just disable that in the camera popup section.

Under camera/audio install that is where you setup the default screen. Change it from 16 to 4. As far as the popup I dont recall as havent looked at that feature in a couple years, I think it is only a single camera popup.

I dont use it often but I believe IE8 has an XP Compatibility mode? Maybe try that. Also check your security settings, admin user rights, and lastly you could download the cab file or OCX and manually install it on the computer.
