zachh1020 0 Posted August 8, 2011 I need help recording my POS screen on my DVR. I just threw something together with parts I had laying around. It worked out in my mind, but, its not actually working. So, obviously my theory didn't work too well. My POS monitor is VGA. I used a VGA splitter, into a VGA to RCA adapter, then a RCA to BNC adapter, then into my DVR with BNC. Jumbled, I know. Like I said, I just threw together some pieces I had lying around. I'm just getting no signal on the DVR. Any ideas are appreciated! Thanks! Share this post Link to post Share on other sites

Thanks! hi. you can do it that way (display register image on cam channel) but you do need to spend money on the components. you will need a powered splitter and a powered VGA to BNC. or you could buy a POS overlay box ? you cant use addaptors like this : Share this post Link to post Share on other sites
zachh1020 0 Posted August 8, 2011 Well, that would definitely be why it isn't working then. Those are the parts I used. Any suggestions of where to get the things you listed? Thanks for the reply! Zach Share this post Link to post Share on other sites

Zach Hi zach. i dont know your location. but you will be looking for parts like this. a powered VGA splitter and powered VGA to BNC. the problem you had with your addaptors is you can set a resolution from the VGA signal. the best way is to use a pos insert box ... then you can search sales and things like void and cancel. (if you have a pc in the same area as your DVR. also before you spend any money see if your DVR has POS. what make is your DVR. Share this post Link to post Share on other sites

zachh1020 0 Posted August 8, 2011 Hey Tom, Would this work for the VGA splitter? http://www.newegg.com/Product/Product.aspx?Item=N82E16817707135 And this for the VGA to BNC? http://www.newegg.com/Product/Product.aspx?Item=N82E16881381027 Share this post Link to post Share on other sites

groovyman 0 Posted August 9, 2011 Actually, you can use a VGA splitter cable in certain situations. I have a few installed the way you explain in the original post. However, with using the VGA splitter cable the signal will be degraded and you will notice the POS monitor may be dimmer with the splitter cable in place. Also, it's possible that the DVR will not detect the signal depending on the quality of the cable and output signal of the vga source. The solution tomcctv originally posted is one of my preferred methods - using a powered vga splitter device along with a vga-to-bnc converter (or vga-to-rca converter paired with an rca to bnc adapter). If your POS System is a normal, everyday computer (like a windows box) you can also install a dual head video card and clone the output to both video outputs. This is really my preferred method of capturing the POS screen on the DVR. One output to the POS VGA monitor and the second output to a vga-to-bnc (or rca) converter. The reason I prefer this method over using a powered vga splitter is that it's one less external device cluttering the point of sale area. Most vga-to-bnc/rca converters that I've seen include a USB power cable. If you can power it via a free USB port on the POS system, fine. If not you can always power the converter with a power adapter that includes a USB port (or two). They're very common now and I use them very frequently. The converters usually require 5V/1A. So, if you use a power adapter like this, make sure the USB output is 5V and at least 1A. Edit: Oh, one more thing. The recorded video from the VGA source may not look as clear as you might expect. Don't expect it to look as sharp as the image on the VGA monitor. However, in my opinion, it will be more than acceptable in both live view and playback.
