# Configure Intercoms as Wireless Readers

Pairing compatible intercoms with Verkada doors allows the intercom’s embedded reader to securely transmit credentials to the paired door over the local network, with no additional RS-485 wiring required. As long as the intercom and access controller are on the same network, users can scan their credentials at the intercom reader to unlock a paired door.

{% hint style="warning" %}

* **Compatible intercoms:** TD33-HW, TD53-HW, and TD63-HW
* **Compatible doors:** Any wired Verkada door (doors with wireless locks are not supported)
* In/Out doors are not supported

You need **Site Admin** permissions to change device settings.

### **Network requirements**

The following ports and protocols **must** be allowed on the local network for wireless reader functionality to work.

| Protocol | Ports       | Transport |
| -------- | ----------- | --------- |
| WebRTC   | 50000-60000 | UDP       |
| mDNS     | 5353        | UDP       |
