looking for VMax-Flex upgrade

i have this unit VMax Flex 4-channel.

i find the software, especially the "backup" function cumbersome. also, don't think the video is all that great. i've upgraded the cameras.

quite new to video surveillance for home. would like to get a few recommendations for a better unit. even it its 8-channel.

better imaging and more intuitive sw interface is what i'd like to get with a new unit. is this possible for under $500.00usd ?

no recommendations for a step up better unit than a VMax Flex 4-channel, anyone?

If you want a better image you will need to step up to HD cameras...there are some HD systems that run on coax cable (that you already have installed) see dahua CVI....lots of sellers and very cheap if you go with a 720p system.

if you want to switch over to ip cameras at a budget (you will need to rewire with ethernet) see this

499 (says sale ends today, but its regularly at 499)
