That is correct!, I thought it was the other way first time round, but when you get it you will see that there are some arrows on it showing direction of the signal. If you really want to you could cut off the BNC's and resolder them in the other direction but yeah.... I wouldn't recommend it.

If its a ground loop issue then yes that will work fine, that's an SC&T in-line ground loop isolator do note that it does lower the video strength a bit so if it gives a weird picture you may need to try adjusting the gains either on the camera and on the software. Also you'll note that it has to go on the camera, then link to the cable these are not bi-directional. Good luck!

Yeah, look at SC&T, they do ground loop isolator baluns. They are a pretty standard part, so I assume your local supplier should have them too

Its an Intel Atom processor (which is arguably underpowered for the job), with integrated graphics (also not recommended), It might be that the price is right, but gut feeling says if its too good to be true, it generally is. I agree with tomcctv, save yourself for a potential woe and keep your coin.

Your right! I forgot about that. It sounds to me like something to do with the permissions, instead of using a power user, have your tried creating a standard user account with that camera disabled? I just tried it with an 8.4.0.1 machine (at the moment i'm only using 8.5 for NVR, gv 650 B type cards and gv900's) and it works ok. 8.5 has been pretty temperamental with VSM, FBR's and some IP cameras, I'd try downgrading (unless you have a B type card or a GV 900 in which case your kinda stuck for the moment) Hope it helps

Crazy stuff, It could be that there was an internal Balun in the screen and the RJ-11 connection was purely there as a propriety connection, if you've put a screen on the camera and it still works then i'd look at a balun and a cheap monitor. Is the access system still working? If it doesn't well bugger it. its 30 years old by the sounds of it, it was worth every dollar they paid for it back in the day if it lasted that long. Replace the whole thing with an off the shelf system, you could spend hours on trying to put a band aid on it and while your offing free labour which is nice you could end up shooting yourself in the foot trying to get it going, and end up replacing it anyway. best of luck!

Awesome solution there! We had to install some cameras in a blast freezer, have a look at pelco's website they have some domes which go down to sub -100 degrees c or something ridiculous that we used. They have heaters pre-installed in them and everything. They did cost an Arm and a Leg, but if you have to do a new install check them out.

There is a lot of information that I managed to squeeze out a Geovision engineer last time he visited us, 8.5 is spec'd for Sandy Bridge processors, They use the Sandy Bridge GPU to encode which makes a world of difference (I should probably start a different thread for this oh well) We have i3's in the field crunching 7+ IP cameras at sub 20% cpu load, and they run fast and stable (admittedly with 4Gb of ram which is pretty cheap nowadays) Downside of Sandy Bridge... lack of Native PCI controller, We have had no end of trouble trying to run Geovision PCI cards stable, ended up giving up on that and reverting back to the core2 series when running GV-PCI cards. So as a Hybrid system I reckon no, leave it as is and build a Sandy bridge system for you IP stuff. It doesn't need to be super high end processor as the GPU is really efficient at encoding/decoding (waaaay better than the CPU) We also have celeron based 8.12 (or there about based systems out there), The reason they generally require next to no power is that they are running older cameras at far smaller resolutions, and less compressed codecs for recording. which means less load for the CPU. In your case I think the card you have even does most of the encoding onboard, allowing much greater frame rates to be recorded, so lowering the recording rate in order to accomodate the Ip cameras I don't think is going to give you the results you want. Best of luck though

Did you enable the additional camera in both Webcam and Remote viewlog in the user account edit page? It sounds like you ticked it for local viewing but forgot to add it for remote

Wow, A lot of different theory's here. Chances are you need to do an AGC (auto gain adjustment on your camera software). If your system boots up 8.4, then your good to go. If your card doesn't work with the software you will get a "cannot find keypro" message. To do an AGC, go to settings--> Video Attributes --> Standard Click on the AGC button and press auto. It should bring some or all of your cameras back up for you. If its genuine this should work for you.

We ended up having a few teething troubles with the G41 chipset too, but after using 8.4.0.1 they seem to vanish. What version of the GV650 cards are you running?

They generally send you an FTP link, with a username and password. But you can also join ezcctv.com they keep up to date zipped versions of geovision software and drivers on there site. They also separate out all the software so your not downloading what you don't need.
