Learn what local streaming is and how it works

Updated yesterday

Local streaming is where the feed from a Verkada camera is forwarded directly to the accessing device, rather than the stream being accessed from the cloud.

This feature reduces the amount of traffic sent and received from the internet. When viewing a camera’s stream, the camera automatically attempts to transition to local stream mode.

Note: When you access a camera’s live footage remotely (when local streaming isn’t possible), the video proxies through the cloud and is cached to speed up retrieval times and playback. This approach enables large numbers of simultaneous viewers without negatively impacting the bandwidth of your local area network (LAN).

Requirements for local streaming

  • The accessing device must be able to reach the camera's private IP.

  • Transport Control Protocol (TCP) Port 4100 must be open—bidirectionally, between the client and the camera.

  • No proxies can be present between the client and the camera.

  • See Required Network Settings for Cameras for allowlisted domains.

Note: A camera will be able to SQ local stream but not HQ local stream when it is configured for H265 but the end user is using an unsupported H265 browser and/or device. For more information see Camera High Efficiency Video Encoding (HEVC).

How local streaming works

  1. The camera’s domain name system (DNS) record needs to be registered.

  2. Verkada Command instructs the computer to attempt to establish a local stream with the camera.

  3. The computer requests the camera’s DNS record.

  4. The camera’s feed is sent directly to the computer.

Step 1: Camera’s DNS record is registered

When the camera connects to Command, it shares its metadata, including its private IPv4 address. Verkada uses this data to provision a public type A DNS record with the private IP address of the camera. Local DNS servers can now resolve requests for the Fully Qualified Domain Name (FQDN) of the camera. This DNS record is utilized for local streaming.

Get a camera's FQDN

  1. In Verkada Command, go to All Products > Cameras > camera's live stream.

  2. Right-click anywhere, click Inspect and locate the Network tab.

  3. Filter results with ping and refresh the page.

    The ping traffic contains the FQDN of the camera you are viewing.

Step 2: Transition to local streaming

When the camera’s live stream is accessed, the computer tries to change to local streaming. If the private IP address of the camera is reachable from the device and the proper domains are allowed on the network, the computer establishes an HTTPS connection with the camera to directly get the live feed.

Step 3: Computer requests the camera’s DNS record

  1. When a camera feed is accessed, Command directs the computer to establish a connection to the FQDN of the camera.

  2. The accessing device sends out a standard DNS request (UDP port 53) for the FQDN of the camera.

  3. DNS resolves the FQDN to provide the private IP address of the camera to the accessing device.

  4. The device attempts to establish an HTTPS session over port 4100. If the device cannot reach the private IP of the camera, the process terminates here and the stream does not transition to local.

    The private IP of the camera matches these settings from Command:

Step 4: Computer establishes a secure connection with the camera

If the private IP of the camera is reachable, the TCP session is initiated. The SSL handshake occurs (TLS 1.2) and the HTTPS session is established. This ensures traffic is encrypted and secure. From this connection, the SQ live feed of the camera is accessed.
