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

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
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.
Video Display Screen (Part code: VDP404)
Each Video Doorbell unit can be programmed to a number of these
compact video display screens allowing you to have several dotted around
your property for maximum convenience.

visitors and allow you to use the touch screen buttons to talk to them
or even let them in when an electronic or magnetic door lock is

The user can choose from the 25 available ring tones and 3 volume levels on the screen.
