I was just at Fry's Electronics and the sales dude was trying to sell me a Lorex dvr. Does any one have any experience with this brand? He said that Q-See, Clover, etc are crap and are returned all the time. I'm not looking for anything too high end. Just the best bang for the buck. Would I be better off in terms of picture quality with a H.264 Pentaplex dvr with 320 x 240 resolution or a MPEG4 with 720 x 240. They are both the same price. I'm more interested in picture quality for live Internet monitoring rather than record quality.

I am in the need of a simple dvr for my deli. I've been offered a Digital Watchdog DW-MAX250 dvr made by Kaltech by a local sales rep. Does any one know anything about this brand? I need a basic 4 channel dvr with 250gb+ h/d and internet monitoring capibilities. This is my first dvr purchase for surveillance and want to spend less than $800. I already have 4 dome cameras w/420 tvl resolution. I'm not expecting the best resolution for recording but am most interested in decent quality for live remote monitoring as well as ease of use. Is this dvr better than the Swann and Q-See brands sold at Costco? Also, is there a big difference in MPEG4 and H.264 compression?
