I've no time for my own reviews at the moment, but I'd like to point you to Terence Eden's reviews (with pics) of some interesting British gadgets:
- Y- Cam - wifi / Ethernet camera you can monitor via your mobile phone e.g. Blackberry, emails you photo on detecting motion, about £150.
- Peepr - free, lets you broadcast to the web or mobile via your computer's webcam and mike, tries to send you SMS text on detecting movement.
Not CCTV exactly, but they sound ideal for personal home surveillance. Even if you have a burglar alarm for home security the ability to keep an eye on your home, literally, and to even take and save photos, can't be a bad thing.
