The wirefree DoorKnox door entry system is a great bolt-on to any security system especially a home CCTV set-up.

Operating as a video doorbell with a 2 way intercom and handy “snapshot” recorder of visitors, the system requires no wiring, working on rechargeable battery cells. A 12V DC PSU is supplied with each part as an option too, which is handy for a more permanent installation.

With transmission distances up to 50M in clear line of sight and a working transmission frequency of 2.4 GHz, these units are suitable for use in most domestic and smaller commercial properties to add an extra dimension to a new or existing security system at little extra cost.

Video Doorbell & Camera Unit (Part code: VDP301)

Perfect for use in porches or sheltered doorways, the video doorbell unit in an attractive silver finish has a rain hood to prevent water from settling on the camera lens as well as a name plate badge so that the occupant’s surname or the house/flat number can be added.

The colour camera produces live images whenever the doorbell is pressed that are transmitted to the display screen (or multiple screens) indoors. If the call remains unanswered for 5 seconds, the receiver/display screen records a snapshot of the caller that can be viewed at a later date. Up to 100 ‘mugshots’ are stored and eventually overwritten or can be manually deleted by the user.

The camera also has built in motion detection that can be operated so a snapshot is sent when movement is detected in the camera’s video signal, a useful feature if used on a building with a communal hall or entrance.

A ‘true black’ IR LED discretely operates at night to add extra illumination to late night callers so a visitor’s face is clear before you answer the door.

If suitable, the door camera has an output too that can be activated for opening an electronic or magnetic lock to allow visitors to enter. The occupier simply presses the ‘LOCK’ button on the monitor to do this, being a more permanent installation this does require the doorbell to be powered using the 12V DC PSU supplied.
