Ok so when I got my CVI dvr some time ago there was no IP camera area on the unit it wasn't until I did a Update that the ability to run IP cameras came about. So seeing unlike other DVR's that Give 2 or more IP camera channels like my 16ch TVI DVR from Brand N at first was like my CVI unit I didn't get IP channels until an update, however rather then Removing 2 Analog channels it went from a 16ch dvr to a 18ch.
So like the 7204 CVI unit is a 4ch dvr with update stays a 4 ch but gives the ability to remove a Analog channel and on that starting with ch4 gives IP ability. With an update it could give it the ability to add all ch to run IP cameras.
So yes I am sure even though the feature wasn't there when released This unit isn't able to be a all IP camera unit. Would be a Way to get all the other OLD NEW Stock DVRs out the door. Sell the unit with 4 841s or 2 and 2 of the 720p ver that may be over stock new items. This gives a way to have NEW stock fill shelves. Thing is it could be used for IP or changed backwards to a CVI unit like right now I could go and uncheck the IP camera on 3 and recheck A3 and it would work back with CVI.
Maybe a Feature Update that people with a Unit now could pay for the feature. When NEW united that area released there could be a V1 and V2 model that one offers the CVI Only like mine came to start with. Or V2 that would change to all IP with ability to use CVI cameras.
