destro_23 0 Posted June 9, 2009 I was just wondering if i could use video balun's with power AND use a POS txt inserter like AVE? but if i do i will need 2 pairs right? Share this post Link to post Share on other sites
Soundy 1 Posted June 9, 2009 Well, it kinda depends where the TVS is positioned in related to the baluns. If you're using the baluns coming OUT of the TVS, then no, you don't need an extra pair, because the text is already a part of the video. If you want to run your serial text info along with the video over your twisted-pair, then yes, you'd need an extra pair on the balun... baluns designed for PTZs would work for this, as they have an extra pair normally intended for serial control signals. However, in my experience, the TVS is usually not located anywhere near the camera, so there'd be little advantage to feeding it over the same line as the camera...

destro_23 0 Posted June 9, 2009 Thanks. Basically this restaurant/ bar that i'm going to do soon will have an Avermedia DVR in the basement office.. 2 stories up is where the bar is located at.. and currently his bartenders are obviously taking money/drinks So my issue is that it's kind of a long distance.. and there already is ethernet cables run to that floor. So using avermedias POS solution is out as i don't think they want to run several serial cables down. So i was also thinking of using geovision as their POS txt inserter can work over lan.. so that eliminates even more wiring... but i've never use geovision cards. OR just use a regular txt inserter like AVE with video blauns with power... My issue is they don't want to run any rg59 as they have ethernet cables pulled already.. just trying to think it out ahead of time. Share this post Link to post Share on other sites
Soundy 1 Posted June 9, 2009 What I've done in a similar situation (not as long a distance, mind you) is to run the serial data over a pair in an unused network line, and placed the TVS close to the DVR - keep in mind that the serial data only actually requires a single pair, from the TX and GND pins at the paypoint, to RX and GND on the TVS. Then run the video and power using baluns over another unused pair (even in the same cable). The other thing I've done in some instances, is to put the TVS under the counter close to the paypoint computer, where I can use a short serial cable to connect them, then run video from the camera to that location, and then out to the office. The camera power can then be home-run to the DVR, or just to a point under the counter. Remember that a text-inserter doesn't care what kind of DVR you're running, if at all - it's just a separate box that overlays the text on the video and then spews that video out. It will look the same whether you're recording to DVR, time-lapse tape, or just viewing it. Share this post Link to post Share on other sites
destro_23 0 Posted June 10, 2009 thanks... this is what i'm thinking now... DVR --> Regular Balun (no power) --> to AVE txt inserter (connected to POS) --> Now video Balun WITH power.. to camera.. and i'll power the upstairs cameras from where the POS computer is. Flow chart should be opposite of what i just listed.. now that i'm thinking about it. but it's late. Again they have all the cat5 already run and extra cables run to basement.. how does that sound?

Soundy 1 Posted June 10, 2009 That's perfect, as long as you have a way to easily route from the camera to the POS area. That's essentially what we've done at the gas stations we have TVS boxes in, except usually just with coax. Share this post Link to post Share on other sites
