I need to buy a "basic" dvd recorder?

I just (finally) got a security camera setup for a rooming house/hotel I work for.

I need a dvd recorder to record portions of the recordings for the police.

Don't get me wrong, it's an ok place, but, when things happen. I need to get them stopped, quickly.

I'll feed from a video and audio output.

I'll do all editing with the security system.

If I can hit "record", "pause record", "continue recording", that's perfect.

If the only option is to record one "take", that's life

It needs to have a video in, a video out, ditto for audio.

That's it!

Can anyone recommend a good, cheap product?

Thanks
