    I'm having the same problem. It's annoying because it triggers the system to start recording based on a motion event. I haven't managed to figure it out but I run my cams from an amateur radio spec 13.8 V DC power supply.

    I'm going to try plugging the power supply into my Line regulating UPS to see if it helps (when the adaptor I ordered arrives).

    right on loop ! That's exactly what I do and it works fine - I never lose my ADSL connection. As for firewall, I use Bitdefender Antivirus/Firewall. I wasn't happy with Norton as I suspected that it slowed my internet traffic down. Bitdefender is cheaper, faster and better IMHO.

    To be honest I have pretty limited knowledge as I've only ever built one Geovision system - a Gv250 in an AMD XP2800 Barton system - but I think you're probably better off with the P4. Ideally you should capture at 640 x 480 as I believe that capturing at a lower resolution with the Geo will reduce the quality of the live image that you see as well as the recorded image ( but I might be wrong ), unless you are using the add-on real-time display card which would allow you to view all cameras simultaneously at full frame rate regardless of what rate your system records at. There are more knowledgeable persons on this forum though and I'm sure they'll set you on the right track

    By the way, I'm using XP Pro and my system is rock solid stable. It's left on 24/7 and never locks up or fails to record.

    Norbain seems to own the Vista brand. I would guess that a lot of the Vista stuff is simply re-badged. I have been told that the Vista camera that I've just bought is a re-badged Baxall so I wouldn't be surprised if they are re-badging Kalatels. At least they're using good kit though........

    Well I've received the lens - a computar 3.6mm Direct drive - and fitted it, but there's a problem. The image is completely out of focus and won't adjust. The model number is : HG3616FCS-3. It's set up as camera two at :

    http://81.86.129.112/. Is there something I'm not doing ? There doesn't appear to be a switch on the camera to select whether or not it's a Direct drive lens.

    It's about $160. I didn't realise the 1/2" lenses were so much more expensive but I saw the camera for sale on Ebay and it seemed a very good deal - £73 for a nearly new current model as opposed to around £350 for a similar-spec new one. I'm hoping to get very good performance from the 1/2" and I can always park the car a yard or so further back if the FOV is not wide enough.

    Thanks, I've found the Computar lens you suggest. It's going to cost around £90 which doesn't seem too bad I suppose, as long as it does the job. It's basically going to be used to watch over my car. It will be around 2m above the ground at the front of the car. The front doors are around 7 ft from the camera. At the moment I'm using a 1/3" CCD bullet cam with a 4.3mm lens which seems to be about right but the FOV could be a couple of feet higher and wider to be perfect.

    Thats the one I used to come up with the 4.5mm. Basically, the 4.5 mm will give me the ideal FOV that I need. It's the rest of the lens characteristics which baffle me. I know I need auto-iris for outdoors but I don't know for example which is the maximum f-stop I can get away with, or whether there are better lenses for use with IR lighting, or what AI/DD/EI lens drive means. 1/2 lenses seem to be fairly expensive and I don't want to waste my money on something unsuitable.

    I just bought a camera for my driveway to cover the car. It hasn't arrived yet and I'm looking for a lens. The camera is a Vista 1/2" HyperHad CCD Day/Night(second hand). It has 480 Lines resolution in colour and 580 in mono. IR cut filter, IR sensitive, AI/DD/EI lens drives (whatever that means !), C/CS mount. By my calculations I need a 4.5mm lens with auto iris but I'm sure it can't be as simple as that. Is there anything else I should look for in a lens to match this camera ?

    I think you could probably get faster than 6fps depending on your connection speed, as long as the server can handle uploading it to the internet fast enough and there are no bottlenecks in between. I've sent you a link via e-mail to my streamed video. Instead of clicking on " 1 window " on the second screen, try clicking on "Multi-view". You'll automatically download a small program and then you should get a multiple display window open. Follow the login details that I've sent you by e-mail and when the camera view opens you should see what your fps is on the right hand side of the screen near the bottom. At least you'll have an idea then.....
