Door entry monitor

  • Records video (2min) or images (80) of callers onto an SD card*
  • Can control access to 2 doors

DoorKnox is a low-cost but feature packed video door entry system. In its basic format it consists of 1 monitor located inside a property and a camera with a "call-button" on the outside of the property.

When someone presses the call-button it chimes the monitor and the person who is inside the property can see the visitor. A two-way intercom then allows the occupier to chat to the visitor and if they choose to they can then remotely operate a door release to let the visitor come in.

As a stand-alone system the SD card will record 2 minutes or 80 still images every time the call-button is activated, which can be played after the event directly from the monitor or from a PC.

Commonly Asked Questions

Q. What does the DoorKnox do?
In its basic format it consists of 1 monitor located inside a property and a camera with a "Call button" on the outside of the property. When someone presses the Call button it chimes the monitor and the person inside can see the visitor. A two way intercom allows the occupier to chat to the visitor and then remotely operate a door release to let the visitor in.
Q. Does the DoorKnox record the visitor if Iím out, so I can see whoís been? How do I view the images?
Yes it does. It can record a small amount of video (2mins) or around 80 images on an SD card inside the monitor. You can play them on the monitor or you could take the card out and play it on a PC.
Q. If Iím not at home can the DoorKnox remotely notify me if someone is at my property?
Yes it can! To do this you need to link the DoorKnox to the "AlienDVR". The DoorKnox's Call button and video output are connected to the DVR. When someone presses the Call button on the DoorKnox camera it ďalarmsĒ the DVR. The DVR records the visitor and can email you three snap shots from the camera to your phone! You could then log into the DVR via the AlienDVR app and see and hear live video and audio!
Q. Wow. Could I remotely open a door using my phone?
Yes using the AlienDVR phone app and its relay controls to open the door. You will need to fit t a suitable electromechanical lock to the door as well.
Q. So one of the real benefits of the DoorKnox is you can link it to the AlienDVR?
Yes, itís the number one feature, making it a really comprehensive system. Most low cost Video door phones donít have this system integration.
Q. Can I see the DVR's output on the DoorKnox screen?
Yes! The DoorKnox monitor can accept two additional composite video inputs from additional standard CCTV cameras or a DVR's video output. If the DVR doesnít have a composite video output you can create one with a composite convertor like the CNV100.
Q. So that means I could play the DVR through the DoorKnox and watch footage on the DoorKnox screen?
Yes you would simply select the auxiliary video on the DoorKnox monitor and you would be able to see the DVR output. The DoorKnox doesnít control the DVR so you would still need the DVR's remote control.
Q. What other features could be useful to me?
You could add a DoorKnox camera to the DVR directly to get a really low cost CCTV camera thatís also a ďdoorbellĒ.
Q. So I can wire a DoorKnox camera to the DVR?
Yes you can! Itís the perfect solution for cameras in entrances and door ways to get a great mug shot of your visitors! The camera just needs 12V power and has a video output that the AlienDVR will see and record straight away.
Q. It is amazing! Can the DVR record sound from the cameras alone if I donít have a monitor?
Yes it can but you need a few simple additional components to do that.
Q. So if I just have the camera can I use the Call button to directly trigger the DVR as well, again without the DoorKnox monitor?
Indeed!! Again you need the additional components.
Q. Can you get all these features with the DoorKnox on other DVRs than the Alien?
No. Some features like the video may work on other DVRís (if itís a multi technology input) but itís unlikely audio or alarms will work, you need to use the Alien.
Q. Can you use DoorKnox as an access control point with a key pad or entry card?
Yes! We do an external camera unit with both those features! This allows yourself, staff or residents an easy and simple way to enter and unlock a door or a gate.
Q. Is it easy to fit?
Very easy. A basic system uses a four core cable between the camera and monitor so itís a doddle.
Q. If I donít have the DoorKnox monitor can I talk directly back to a DoorKnox camera from the DVR?
Not yet but we are working on it!

Wireless Key Pads - use as an alternative or in addition to a key fob to trigger the RX

Adding a fixed place for an approved user to access a secure area by simply keying in a 6 digit entry code to activate the opening of a door or gate up to 100 metres away, the keypad design has none of the risks associated with staff losing or forgetting their keys.

These compact keypads are available in black or white to suit the installation and have 2 transmission channels to control up to 2 separate devices. A transparent weather shield protects the keypad and allows installation in an external location whilst a back lit keypad makes night time use easier.

Our receivers pair with our key fobs and key pads in seconds for complete wirefree control!

Compatible with any of the key fobs or keypads in the range and available in a choice of black or white. For extra security our receivers use rolling codes which change on every use this means they are never duplicated.

1 Channel Receiver

Pair this with the 1 button key fob for use as a panic button or simple control of a single device, or with the keypad to open one electric door or gate.

4 Channel Receiver

This unit can receive a trigger from all 4 buttons of a key Fob or both channels of the keypad.

The receiver also has 4 push button controls on the front of the unit itself which when pressed simulate the same as the key fob buttons being pressed activating any of the 4 channels in use. This means that the 4 relays can be activated without a key fob or key pad.

2. Add a wirefree keypad

A wirefree keypad is a great way to secure an outbuilding, stock room, or even a server room as it restricts access to code holders without relying on locking the door with a key.

3. Add a wirefree receiver

The 4 channel receiver units are not just controlled by keyfobs or keypads they have their own set of buttons on the front panel to allow easy relay control of a device such as an electronic door release.

4. Why not wall mount a wirefree keyfob?

The mini 1 channel receiver is small enough to fit inside an alarm panel so why not use a 1ch keyfob in the wall mount bracket as a panic attack button.
