  • Electric drill/ Hammer drill *

  • 5/32 drill bit for wood *

  • ⅜ concrete bit *

  • 7/16 inch socket w/ ratchet

  • Philips screw driver

  • Level

  • Pencil

* The use of this item depends on the mounting surface you’re working with. 

Wiring Requirements

  • 16/2 or 18/2 for power (see below for recommended distances)

  • 22/6 for Wiegand

  • One CAT 5e or CAT 6 for wired ethernet

  • Earth Ground (see Step #3 below for earth ground requirements) 

Installation Instructions

Now that you’ve organized the items included with your Video Intercom unit and gathered all other necessary tools, you can complete these installation steps. We recommend that you have an additional member of your team assist you during 

this installation process. 

Note: When locking and unlocking the Video Intercom unit, press the faceplate inward to compress the seal and then turn the lock. This will alleviate any pressure on the lock and allow the lock to spin with less resistance.

  1. Mark the Video Intercom’s four mounting holes on your installation area’s surface.  It is recommended to have a second person help during this part of the installation.

Keep in mind that the Video Intercom’s installation height must follow ADA Guidelines, which means that the top of the Video Intercom’s screen must 

be no higher than 48” from the ground. The center hole for wiring should be 46.5” from the ground.   Once you're satisfied with the location of your markings, use your level to make sure that each marking is properly aligned. 

  1. Drill the four marked mounting holes. There are four mounting holes on the back of the Video Intercom, two at the top and two at the bottom.

If you’re installing into a wood surface, use a 15/64” bit. If you’re installing into a concrete, block, or masonry surface, use a ⅜” concrete bit. You’ll then need to insert the provided wall anchors into the drilled holes prior to mounting the Video Intercom to the wall. Use a hammer if necessary. 

  1. Feed the wires (power, Wiegand, ethernet) through the wire hole (roughly an inch in diameter) in the back of the Video Intercom while minding the following wiring and grounding requirements: 

The Video Intercom’s power wiring recommended distances are as follows:     

Wire Gauge

Max Distance


150 ft


100 ft


50 ft

    The Video Intercom’s grounding requirements are as follows: 

  • Good earth ground is required for surge damage protection.

  • 16 gauge stranded wire or thicker.

  • Wire must be connected from the Earth Ground terminal inside the Video Intercom box to a ground rod or cold water pipe.

  • The length of wire should not exceed 50 feet. 

  1. Use your ratchet and socket to mount the Video Intercom unit using the four provided lag bolts. We recommend that you have somebody help you hold the Video Intercom while screwing in the lag bolts. The head for the lag bolt is 7/16 of an inch.

Note: Use the provided security key to unlock the Video Intercom and access the lag bolt mounting locations. 

  1. Using a phillips head screwdriver, connect the wires to the Video Intercom screw terminals using the wiring diagram below. 

Connect the two AC power wires to the two AC terminals on the screw terminal. Connect the other end of the wires to the AC terminals on the MGT-2450 transformer.

Connect a 16 gauge (or greater size) stranded wire to Earth Ground terminal in the unit.  The other end of this wire should be connected to a suitable ground less than 50 feet away.  

Connect the Wiegand wires coming from the 734 access control system module to the following connections on the Wiegand Interface Board:

  • D1 (WHT)

  • D0 (GRN)


  • 12V (RED)

Connect the ethernet cable to the RJ-45 jack on the left side of the 

main board labeled Ethernet.  Connect the other end of the cable to the internet source.

  1. Plug in the transformer to power up the Video Intercom unit.

  2. Wait for the Video Intercom system to boot up.  This should take no longer than one minute and you should see a loading screen similar to the one below. 

  1. Complete the Video Intercom unit’s setup with LittleBird Support.

All LittleBird Video Intercom units ship pre-configured and should immediately connect to the LittleBird cloud, download the resident directory (if the site is live), and connect.  

However, there’s a final check of systems and completion of onboarding that must take place. To set up this final check, call or email LittleBird Support at (602) 607-4620 or [email protected]. If you choose to call and a LittleBird technician isn’t immediately available, you’ll receive a callback within 8 business hours. Please include the site name, Video Intercom serial number, and contact information in the email or voicemail. This callback/contact will inform you of successful installation and final check, or note issues if applicable. 

A completely setup Video Intercom screen will look like the image below and should include your correct property name.

  1. Close and lock the lid with the provided keys.
