The Verkada TD52 Video Intercom allows organizations to enhance security and answer calls from anywhere with sharp video, clear audio, 4 smart receiver methods, and intuitive management and security tools in Verkada Command.

Add the serial number to Command

Add the intercom serial number to Command.
Once you add the serial number and activate the intercom, a new tab opens, showing the video feed from the TD52. At the top left of your webpage, a menu displays the setup checklist. We recommend to follow the setup checklist.

Configure setup checklist options

To access all configurable options, at the top right, click Settings.

Change device name

From the setup checklist, click Change device name to open the Settings page.
With the Settings page open, select the current name to change the default name.

Pair a door

Note: Paring a door is not compatible with the AX11.

From the setup checklist, click Pair a door or on the Settings page > sidebar, click Pairing.
Click Add a door.
Next to To Verkada Access Controller, click Select.

You should see a list of the access-controlled doors in your organization.
Once you select a door, it appears as a paired door and can then be unlocked from the live page. To unlock the door through a call, receivers are required before using the TD52.
When the door is paired, you are prompted with information on how a call ends. You can also now see these toggle options:
- Ends call on door open after intercom unlock—This is the default and indicates that the call from the intercom will be stopped when the unlock button is pressed.
- Ends call on door open while intercom is dialing—Indicates that if the door is unlocked and opened while dialing, then the call is ended. For example, if someone watching a desk station live feed unlocks the door before speaking, then any ongoing dialing will be ended.
- Beep when Unlocked—Indicates that the intercom will make a noise when the receiver initiates a door unlock.
Once a door has been paired, you can skip to setting up the receivers.
1. To add context cameras, skip to pair camera(s).
2. To configure I/O devices, skip to configure I/Os.
3. To configure receivers, skip to add receivers.

Pair camera(s)

From the setup checklist, click Pair camera(s) or on the Settings page > sidebar, click Pairing.
Click Add Camera to see a list of cameras in your organization.
Select up to 2 additional cameras for context. You can also select other intercoms as a context camera.
If the paired door already has a context camera, it will appear as the first paired camera.
Once additional cameras have been added, they will appear on the Live page of the intercom (left side of the video feed).

Configure I/Os

From the setup checklist, click Configure I/Os or on the Settings page > sidebar, click I/O.
In the I/O section, select your I/O, as needed:
- There are 2 inputs and 1 for output. If there is anything wired into the I/O port on the TD52, this is where the exact I/O function is selected. Learn how to wire a TD52.
- Learn more about the I/O types.
Enable your input device: Select the input number that corresponds to the port used in the I/O port, then select the correct input device type. For example, if a door position indicator (DPI) is wired into input 2 on the I/O board, then select input 2 > DPI.
Enable your output device: Select the correct device that corresponds to what is physically attached to the I/O port.

Add receivers

For details about how to add receivers, add/edit schedules, and add/edit call lists, see Add and Configure Receivers in Intercom.

Once a receiver is added, then the intercom is ready to begin making calls.

Types of I/Os

The intercom allows for various types of input and output devices to be attached and interface with it. The I/O port allows for 2 inputs and 1 output to be attached to it.

Input

The input is a set of 2 dry contacts that watch for Normally Open (NO) or Normally Closed (NC) from the device attached to the I/Os.

Call Trigger	Any input that sends a close signal to the intercom can be used as a call trigger. For example, if a PIR motion sensor was used, then the intercom would make a call when the motion sensor is triggered.
Door Position Indicator (DPI)	Any contact that sends an open or close signal. Typically DPIs are contacts that are contained within or on a door, and are used to determine if the door is physically open or closed.
Request to Exit (REX)	When a close signal is made, then the intercom unlocks the door that it's paired to. For example, a REX could be a standard button or a PIR motion sensor.

Output

The output is a dry relay with ports for NO, COM, and, NC. The output can be used to trigger a door unlock.

Door Unlock	Upon door unlock, the dry relay triggers and sends a close or open signal to the device attached to it. If the door unlock is to be used to trigger the lock or unlock of an electrified lock, then proper external power supplied or power controllers are required to operate the lock.
Chime	Intercom output can be used to set a chime.
Call in progress	Intercom can be used to trigger call in progress.

Other configurable settings

General

General is a configurable set of options that affect the intercom and information about the intercom.

Continuous Audio	If enabled, the intercom continues to record and stream audio when not in a phone call. For example, the intercom can be used to listen to what is happening around it, even when no call is in progress. (This audio is recorded.)
Tamper Events	High-to-low sensitivity, these events show in the Events page (left sidebar) and the Events tab (at the top).
Cloud Backup	Use to continually save footage from the intercom camera.
People History and Face Detection	Enable People Detection to search for individuals who are visible on the intercom. Enable Face Detection to allow for more granular information, such as location people of interest (POI).
Time Zone	Time zone is based on the address assigned to the intercom. For example, if the intercom address is Toronto, Ontario, Canada, then the time zone is shown as EST/EDT.
Device Status	Current status displays as online or offline. If offline, the amount of time is also displayed.
Serial Number	Located on the I/O cover and side of the box of the intercom. See also Add a TD52 to Command to learn more about serial number locations.
Model	Model name and number.
Date Added	Time and date the intercom was added to Command.
Firmware	Displays if the intercom is up to or out of date.
Local IP Address	Dynamic Host Configuration Protocol (DHCP)-assigned IP address. The IP address and the subnet mask displays.
MAC Address	Located on the I/O cover of the intercom.

Call

Call is for calls made from the intercom to the receiver. To access the Call setting, on the left sidebar, select Call.

Press Intercom button to End Call	When the Intercom button is pressed, a call can be ended. This is toggled on, by default.

Dial Key to Accept Call	When receivers are phone numbers, a phone call from the intercom to the receiver is made. Two-way talk does not start until the call is accepted. The dial key starts the call. It is a hashtag (#) or asterisk (*).
Dial key to unlock door	Anytime during a call the door paired to the intercom can be unlocked. The key to unlock the door is any number on the dial pad.
Intercom phone number	Phone number that is used to call the receiver. If calls should be received even when the receiver is silenced, then consider adding this phone number as an emergency contact.
