mikef Posted January 11, 2011 Posted January 11, 2011 I'm looking to fit a shop with a 16 channel dvr, but they wont to use a 42" Television, I've told them the picture is going to look rubbish because of the size, even using the VGA output it's still not going to look the best, Samsung do a SRD-1650 with HDMi output for the monitor, has anyone used a DVR with HDMi output if so whats the picture quality like?, the camera's are going to be all 520TVL high resolution colour camera's so I shouldn't have any problems there
hpotter Posted January 11, 2011 Posted January 11, 2011 dvr still be recording at sensible level, so ok for replay on local monitor. Whats the system design purpose?
Guest Oxo Posted January 11, 2011 Posted January 11, 2011 Cannot see the issue with a 42". Used bigger. Every corner shop now has a big screen with dire kit. Funny really, cams not looking at high value goods for instance. Not watching blind corners. Loved doing retail, one set up followed the biggest looking "CRIM" around the store. Followed her all around the store, notified manager ( remember was setting up cams). He asked me to be there when she was stopped as she left. Was a store detective...................................we did all laugh eventually........... Biggest shoplifting, OAP`s with tins of tuna, salmon, corned beef. Well it was then. Blimey someone stop me, just stepped back in time.
PeterJames Posted January 11, 2011 Posted January 11, 2011 I agree with Paul we have several leisure centres with 42" plasmas behind the reception showing 30 or so cameras looks great, you need to make sure that the monitor is positioned following the below chart ......... Size..........Viewing Distance 26 Inch – 3.2 feet to 8 feet 30 Inch – 3.8 feet to 10 feet 32 Inch – 4.2 feet to 11 feet 34 Inch – 4.4 feet to 12 feet 40 Inch – 5 feet to 14 feet 42 Inch – 5.5 feet to 15 feet 46 Inch – 6 feet to 16.5 feet 50 Inch – 6.5 feet to 17.5 feet 55 Inch – 7 feet to 19 feet 60 Inch – 7.5 feet to 21 feet 63 Inch – 8 feet to 22 feet 65 Inch – 8.5 feet to 23 feet Read more: http://www.brighthub...x#ixzz1Al56Fj9I
james.wilson Posted January 11, 2011 Posted January 11, 2011 Vga output as fine as long as it can output true res higher than 640x480 ie 1280x1024 etc securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
digitalwitness Posted January 11, 2011 Posted January 11, 2011 Put a system in my own house and was expecting it to look poor on the 50" Plasma but was quite surprised despite the fact it is run off the composite output, obviously split screen looks better than full screen but looks much better than some 19" flat screens. Really it depends heavily on how a screen renders standard definition and the change in aspect ratio, do not be miss lead by DVRs with HDMI and promise HD video viewing, many full featured VGA outputs can easily match them. I can understand your concern but if you have the opportunity test it, you may be surprised.

james.wilson Posted January 11, 2011 Posted January 11, 2011 I do think that's the vga implimention ie my pc is vga and it looks great. Depends on the output res of decent dvr with Vga again imho securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

More recently with the addition of HDMI, they have had to up their game and implemented higher spec VGA ports. These higher spec vga ports are still cheaper than implementing HDMI (due to royalties etc). HDMI has been used mainly for marketing reasons and in my experience do not offer better performance than the higher spec VGA ports offering similar performance but with the cheaper VGA screens, similar result but cheaper overall cost.
Driller Posted January 12, 2011 Posted January 12, 2011 The VGA out of my DVR goes through an HD multiroom amp to all the flatscrens in the house using component video. Looks ok although the images are a bit cropped (I guess) due to the aspect of the tvs.
