CCTV for home. Basic or pay a bit more? Help me out...

Bet you've had something nicked and are now going way over the top.
Trying to prevent this...
My main reason for doing this is because I'm into tech, fancy doing it and want that added bit of security.
What I really dislike is paying for someone else to do it, when I am preparped to do it myself. Which is bizarrely, why I ended up here at DIYnot; "DIY can be both challenging and rewarding - this is where DIYnot.com aims to help. Our expert teams have brought together hundreds of information pages. Why not Do It Yourself?"
In this instance, I've been quoted between £800 and £1200 for supply and install of 4 cameras. I know for a fact the goods offered in these quotes ARE not to the quality/spec of what I've got.
I've spent the money saved on the labour, on better quality kit... and when it's installed, I'll have achieved what I set out to do.
Whether it works or not, who knows, it's been fun and I've learnt a bit on the way.
What cameras did you get (list part codes)?
A Samsung SCO-2080RN/P only needs about 600ma at 12v DC or 300ma at 24v AC. So a PSU with four 1A 12V DC outputs would do the job fine. Get one with more outputs if you think you might expand.
Presumably you don't have a huge cable run between PSU and cameras, like over 100m?
Whether you use an AC or DC power supply is largley irrelevant in a small home installation. You would normally use AC power if the cable run is very long to combat the voltage drop.

Mark,
I've 2x SCO-2080RP and 1x SCV-2080RP, both are based on the same internals/specs I think. Longest run is going to be about 15m!
Both manuals state; DC12v/4a or AC24v/2a. If I can get away with less, then I stand more chance of being able to run 4+ from one PSU. It's just which PSU.
Based on my maths & your figures, a DA667/8 (12V DC 8 x 1Amp) should be well upto the task of potentially running 8, no?

The manual recommends you use their Samsung branded power supply which is 12V, 4A. If you look at the specifications, you'll see that the camera draws 6.8W maximum, so not 4A (it would be getting rather hot dissipating 48W!! )

I don't understand electrics, but am good friends with a sparky. I'm guessing what you're saying backs up Mark's comments above, which means I can consider other Dantechs, ones which may offer more room for expansion?
But don't be tempted to load them up to the limit.

Dantech DA396, 12v 4x1a - sufficient?
Based on the above, yes, that's ok.But don't be tempted to load them up to the limit.

Dantech are a good make and we fit hundreds of them without any bother (in normal use).
