Video door entry system colour handsfree?

B&Q used to sell a video door entry system kit last year for about £90. No longer have them. It was a handsfree colour audio/video monitor and intercom only. Not to open door but just to see who the caller was at the door.
Does anyone have one of these. Can anyone give me name, model and supplier from the handbook?
Or, can anyone tell me where to get a similar item at a similar price in UK. Wouild be appreciated.
