A couple of months ago I set up a CCTV system for someone I know.
He had purchased 4 x Cameras (Co-ax, not IP), and a cheap and cheerful box to run the cameras. The box has 4 x coax inputs, 1 x coax output, and an ethernet port for remote viewing and management.
The box was installed and wired to the cameras and I only went to configure the box and get it online, but intructions were missing so I never could figure out how to get the recording function to work.
Then even more disappointment when we realised the box used Adobe Flash for the cameras, and neither of us had any joy viewing via our android handsets (even when I manually downloaded and installed flash).
He's now said he would like to add another 2 channels meaning we need a new box, and this would be a good time to get something that works with our phones as well.
Unfortunately it is desireable to keep the legacy co-ax cameras. If there is something with 8ch at a reasonable price this would be nice in case of future upgrades.
This will be for business premises so needs to be reliable and record in reasonable quality (I believe the cameras are around 1MP).
On the flip side, as he burnt a load of money getting some "professionals" to perform his original install, funds to actually get it all sorted are limited so we are looking are the cheaper end of the market. There is no server on site that we could use to store the recordings, or to connect IP Cameras to.
