Crazyandrew 0 Posted December 24, 2011 Hey guys, if you buy a DVR, is HDMI port necessary to you? Just want to know that. What's the difference from VGA port? And is the video fluent if you connect a high definition camera to DVR? Share this post Link to post Share on other sites
Soundy 1 Posted December 24, 2011 VGA = video graphics array, an analog high-resolution video standard.* HDMI = High Definition Multimedia Interface. It uses the same digital video signal as DVI (Digital Video Interface), but incorporates digital audio as well as other signals. On a computer desktop, a digital signal (DVI/HDMI) will usually look a little crisper than VGA; in general though, on a DVR, there should be little noticeable difference between the two... look for whatever is compatible with whatever monitor you want to use. If you want to run your DVR's output through an A/V receiver, you'll probably want to make sure it has HDMI (since most receivers now support multiple HDMI inputs). *Technically, VGA also refers to 640x480 resolution, with higher resolutions being referred to as SVGA (super-VGA, 800x600), XGA (extended graphics array, 1024x768), WXGA (wide XGA, 1280x768), and so on... see the complete(?) list here: http://en.wikipedia.org/wiki/Graphic_display_resolutions. All these resolutions can be supported via VGA, DVI and HDMI. When you refer to a "high definition video camera", are you talking about a consumer camcorder type device with HDMI or other HD output? You won't find many, if any, DVRs that have HDMI inputs. The only current standards for recording high-definition surveillance video are IP (network cameras) and HD-SDI (Serial Digital Interface, a broadcast standard). The latter is new to the market, so there's not a lot of selection out there yet, and is limited to 2MP (1920x1080). The former uses the same type of network as your internet connection and there are cameras commercially available in resolutions up to 29MP (although that will set you back about the cost of a small car).

blake 0 Posted December 26, 2011 The Qvis Apollo HD dvr's have hdmi, and the picture on an hd tv is supposed to be pretty good compared to a standard video out or vga on a regular dvr. Share this post Link to post Share on other sites
SecurityNub 0 Posted December 28, 2011 I believe my camera was $80. With that said, the difference between my BNC--->RCA connector and my HDMI cable is ridiculous. So much nicer. There is not a person yet who I have asked who didn't notice a big difference. HDMI all the way. But I have not tried the VGA. Share this post Link to post Share on other sites
