2 video signals on a single twisted pair
Blake CCTV replied to Blake CCTV's topic in Video Transmission/Control Devices
Thanks guys I was thinking about using a normal coax combiner and then sending the output into a balun and doing the same at the other end, which is what i think you are suggesting SDM group. Soundy: your idea sounds like it could work but would probably be too costly. -
Can anyone recommend a good 3g wireless router

DVR output using CAT5
Blake CCTV replied to third eye security's topic in Video Transmission/Control Devices
gungate has a good idea try using an active balun the best type are the ones with variable pots they give a more precise adjustment than the ones with dip switches. If you have an oscilloscope you can check the video signal coming from the camera and at each point along the signal path eg. at the camera output, DVR input, DVR monitor output, the remote monitor input. you are looking for 1v of video signal at each point. Something simple that you can try is to bring the remote TV locally to the DVR and connect it using a short piece of cat 5 cable and your baluns. This will elimnate the long cable run (which isn't that long for cat 5) and earth loop faults. what is your location -
Hi can anyone tell me if you need to use a rotakin to commision a cctv system in order for it to comply with BS 50132-7 or is this just a guideline. Thanks in advance Richard

Hi, does anyone have a design tool or method for calculating the pixels per inch of a 5 mega pixel camera at certain distances. Thanks in advance
-
Sorry I didn't make it clear on the last part of my post when I said that I know what the definitions are for analogue I meant that this is defined by the percentage of the screen that the person occupies but obviously with megapixel cameras the subject can be a lot smaller than an analogue picture but can be zoomed into a certain amount before the quality is affected So its not as simple as just measuring the percentage of the screen that is occupied by the subject.

Does anyone know how many pixels per inch or cm that an image needs to consist of to be defined as identification recognition detection and crowd monitoring. I know what they are for analogue cameras but not megapixel cameras. Thank in advance Richard

Help I have a remote PC that has a display fault when the monitor was turned on it would go off again as there seems to be no video coming from the video card i thought i might be able to connect to it using VNC but still have no display although i can connect to it. I was trying to reboot it but can't do this without the display, any ideas?
-
Thanks for the ideas I had tried these but to no avail as the PC is a DVR and that program has to be shut down aswell I have abeen to site today and confirmed it is the video card, so at least I have learned that video on VNC will only work if the video card is ok on the remote PC. Thanks anyway

Tricky site to site DVR multiple site link
Blake CCTV replied to Stuartbe's topic in Installation Help and Accessories
you are right it is a type of ground loop hum compounded by the different phase. running the reomte monitor from the local psu should help I had this problem once and found it was because of a different phase. If you're not that far apart have you thought of a using a good wireless link which will eliminate any phase/earth problem. I always steer clear of wireless links but this may be the best budget solution -
Glad you got it working I now know what a null modem cable is, I have opended plenty of DS2's and found WD drives in them although I do know that DM's can be fussy with there drives. Are you formatting them as FAT32 before installing them?

Try contacting tech support at EZCCTV they always help me

Its been a while since I have dealt with a DM and Hyper terminal but from what I remember the data pair for the com connection needs to be reversed. sounds like your doing everything else right let me know how you get on
