Way off I think !!! 500 kbit/s equals 500 x 3600 x 24 x 31 = 1339200000 kbit/ month Which is 1339200000 / 8 / 1000000 = 167 Gbytes/month You are a factor of 62 out !!! (Yes I know 1024, not 1000, but close enough and makes it simpler)

I'm looking to get some pricing on Dahua DVRs and Cams (IP/ analogue, PTZ and fixed) and I'm being told by Dahua that Adata are the UK exclusive distributor - and then told by Adata that they don't stock most of it. Anyone got any other sources, official or otherwise, UK or mainland Europe, they could recommend (here or by PM). Thanks.

The PAL analogue video system on which they are ALL based is a theoretical 625 line (like our recently departed analogue TV), but some are outside the visible range, so 480 is probably about right. What matters more is the quality of the imaging chip, the lens, and the lighting. Its a bit like the difference between watching 'old' analogue TV on the monitor in the TV studio (which looks better than digital freeview!) and a crappy old VHS recording!

Lovely website though - would you buy a "digital video recordes" from a man with a one page website who couldn't even spell! PS *I* am genuine at least - so any real answers still welcomed!

Hi All from England. We're a small company working mainly in wireless data links - both for Internet and private use (like radio station transmitter links). We keep getting asked about CCTV - either to provide complete systems, or because we have experience in getting remote viewing to places where landline phones dont reach. Hopefully we can learn a lot here, and if we can help on any radio / wireless / IP questions - dont be afraid to ask!

If I stuck to what I knew I'd still be selling microwaves and kettles from Comet as I did age 17 many years ago. Life, the industry and technology move on, and if you don't, you (business wise) die! With respect I'm not sure that expanding ones knowledge and offering a better range of services to your customer is necessarily 'dabbling'. PS And you mr nuts would be inspecting elephant sh1t with the circus!!!

Hi guys, to date we have installed only IP cameras as we come from an IT background and most stuff hase been single cam for remote viewing at equipment sites/ towers. We now have a few more 'conventional' installs with 4-8 analogue cams back to a DVR (and then onwards for remote viewing). Is there anything wrong with continuing to use our familiar, easy to install (outdoor rated, UV resistant, shielded) CAT5 cable with the baluns that take both video and power? Is there a better solution? Is there an accepted 'max power loading' down CAT5 for cameras with higher power requirements (eg IR LEDs, but clearly not a heated PTZ)? Does anyone make a patch panel for the head end that breaks out lots of RJ45 socket connectors into a multi way PTC fused power panel plus BNCs for the video (ideally in the UK) Thanks in advance.
