Welcome to the forum, what sort of cameras do you currently have (are they recorded and if so onto what?). Can you make out fine details on the current cameras?

If its on all cams then it maybe a faulty graphics card, or corrupt graphics card drivers, or a faulty geo card. Not something I have seen before, but have seen blocky graphics before on a faulty graphics card a long time ago (not on a geo system, and not like that pic, but random blocks here and there), worth checking out anyways... Maybe try reinstalling the geo codecs too, in case they are shot... Its a weird one, guess it could be anything really!

The forum only supports genuine cctv cards, Clone cards, or pirated cards are not supported.

Just tried it on my 1480 with v8.2 and its the same, as soon as you hit the scan button, it switches to single camera view, changing to any other view turns of the camera scan feature so you can only do it on one view. You can do it in control center, which I normally view the cams on over the network on my laptop, you can use any view with camera scan in that, so cant see why they dont have it in the main dvr. Not sure if it used to do it in a older version or not, as I dont usually use the camera scan feature.

No matter how fast the DVR can push out images for the internet (no idea on that model) your main limiting factor is going to be your internet connections upload speed at the DVR usually. On most (at least in the UK) broadband/high speed connections your download speed (ie downloading webpages) is always a lot faster than your upload speed (the speed at which you can push information onto the internet). For example, the broadband service I use, shows that my speeds at present are 7968Kbs for downloading, but only 448kbs for uploading. Your DVR is uploading to the internet, so that is likely to be the bottleneck. Usually the only ways to get faster fps, is to either get a much faster service, or reduce the resolution viewed over the internet, or change the codec or codec settings if possible, but usually there is a tradeof the faster the lower the quality, as you cant squeeze a quart into a pint pot, or whatever the old saying is

Few questions, Was it working before, then stop working? Or is it a new setup that you are trying to get working for the first time? How is it wired up (not familiar with the ds2) is it using up the coax or rs485/current loop for the telemetry control? (also is the ds2 setup to use the right telemetry format, not sure if its automatic on that or if you need to set it in a menu or dip switch) Does anything work telemetry wise? Are you getting video? On the BBV, there is a test mode, its switch 8 on that model (there is a set of dipswitches on the board) - the test mode should activate all functions on your device (pan/tilt/zoom/focus etc) one by one so you can see everything is wired up at the bbv end correctly, and functioning. The cable LED (light emitting diode, a small light) on the board should be on or flashing before you start the self test, if not something is probably wrong with the board (or it has no power!) I have enclosed a link to the bbv manual in case you need it, pay attention to safety (as you can get electrocuted if you are not careful what you touch, especially if its a mains unit, and heed the warnings about isolating any moving parts etc before working on it etc...) http://bbvcctv.com/manuals/Rx200-300-400P-400DC%20manual%20rev5.pdf Has anything changed recently in the setup of the system, did the fault occur intermittantly before failing fullstop? How long is the cable run, what type of system is connected to the BBV etc. Not sure what else to add without further info, but that should be a start..

Nice little unit, seems very expensive for a plastic box, 3 bnc sockets, 1 2 way connector, a relay and a bit wire or pcb though.. For that price it should have the photocell built in (or on a plug in wire), with adjustable settings etc.

PC power supplies can be ran with just a 12v load, as long as the max amp for the 12v rail is not exceeded. The only other connection needed (on atx style power supplies) is the power on line, which needs to be powered to turn it on. Apparently, atx supplies need a minimum of about 20w load for best regulation to take place, but its not something I have noticed when using one on a test bench to power cams, but its something to bear in mind that the regulation may not be great if the load is not enough.

Its probably a limitation on the search facility, there is often a minimum length that can be searched for succesfully on phpbb forums. You can use google to search for D1 within this site, a example link is below http://www.google.co.uk/search?hl=en&as_q=d1&as_epq=&as_oq=&as_eq=&num=10&lr=&as_filetype=&ft=i&as_sitesearch=http%3A%2F%2Fwww.cctvforum.com&as_qdr=all&as_rights=&as_occt=any&cr=&as_nlo=&as_nhi=&safe=images

It depends on the current drawn, as the higher the current, the greater the voltage drop.. 220v should not be used in cat5, it should be ran in seperate mains rated cabling, and it should not run close to (parallel) with video. Local safety/wiring codes will need to be adhered to also, for safety and insurance purposes..

It would depend on the type of wire (gauge, solid core, stranded), camera power type (AC or DC), voltage (12 or 24v) power draw of the camera, and the length of the run, as these would decide how much voltage drop you would get in the cable.

If they want like they see on CSI on television, where they can pick some footage and zoom right in to see clearly, then its not going to happen with normal cctv cameras. All the zoom does, is make the pixels bigger, if the detail is not there, its not there. With analogue cctv you really need the zooming to happen when you are recording, ie zoom the lens in to get the detail recoded, trying to do it after the event wont bring much luck usually. Megapixel cams would allow more zooming in without the pixelation, as there is more details to start with... Zoom may help a little, lots of DVRS, some multiplexers etc do allow it, but remember, garbage in, results in zoomed up garbage out

Welcome to the forum! What is a 'interface' business?

Did you get a manual with them? If not, for anyone to be able to offer suggestions, then the makes/model numbers of the cams would be useful, in case anyone is familiar with them.

Welcome to the forum!

If possible examples of movement shots at night would be good, to see how it handles car headlights, and objects moving at speed at night.

Here you go, http://www.norbain.co.uk/downloads/manuals/scc-931tp.pdf Pinout for the alarm/rs485 connector is included in the manual above.

Would the training not be country specific? Different countries have different rules for data protection/privacy etc. What country are the operators working in, and what country are the viewing?

What is CQC?

The question was not about a external psu, it was about using the one in the pc that is the DVR..

I have not done that distance before, but I would try active baluns, both active receive and active transmit. Power local at the camera, active trasmitter balun at the camera, sending video over cat5e to a matched active receiver balun at the pc side.

What about a small circuit containing a light dependant resistor (ldr), to switch a transistor or relay, set up so that if you stick the ldr on the corner of the monitor, when the fault occurs, and the screens background goes black, the resistance changes enough to trigger the relay or transistor, giving a signal to your existing monitored alarm setup?

The psu may be in a restricted room, but if its powering the cameras, then its output lines are connected to the outside world (assuming the cameras are outside of the control room). Unless all cables are untouchable, this exposes the psu to risk, and they are designed to shut down when the are exposed to a direct short, or on overvoltage or other fault condition.

What if someone comes along and shorts out one of the cables, unless you have a fuse that blows faster than the psu itself decides there is a fault and shuts down, you have a dead system and a bunch of dead cameras. Or worse, what if someone comes along and injects extra voltage into the low voltage line, instead of just a blown camera, you may end up with a blown psu, no recording, and no cameras..... At best, it would probably just shut down the psu, but you would then not be recording anything.... Seperate PSU means the PC does not go dead in a fault condition like that.

If its like the commandview dome I just picked up, which is also a 2MP imager, the resolution is even lower than figured it would be. The imager is 2 megapixel, but its imaging a fisheye image, so only the 'circle' produced by the fisheye is usd by the imager, the corners are wasted. This means the 2MP imager is really only using around 1.3ish Megapixels, as the rest of it is not getting any image to work with! Im tempted to see what its like if I stick a normal lens on, I would lose the IPIX effect, but at least I would be getting the full 2MP....
