My Frigate Camera Has a Speaker. Lumen Lets Me Actually Use It.

I have a Reolink E1 Outdoor on my front porch. It has a speaker and a microphone — always has. I’ve known about it for two years. I also have Frigate running, ingesting the stream, flagging every person who walks up the path. What I couldn’t do until recently: say anything back to them. Most Frigate setups are one-way by default. You watch; you don’t talk. That changed with Lumen’s two-way audio beta.

Why Frigate Ends Up One-Way

Most cameras that work with Frigate send video over RTSP. The stream flows one direction: camera to Frigate to you. But many of those same cameras — especially anything marketed as an indoor security cam, baby monitor, or outdoor cam with a speaker grille — support a back-channel for audio. You talk through your client; the camera’s speaker plays your voice. The protocol support is built into go2rtc, the stream multiplexer Frigate uses under the hood. The infrastructure is there. What’s been missing is a client app that actually exposes the button.

I spent two years with a camera that technically could talk back to people, connected to a system that technically supports it, with no way to trigger it from my phone.

What Lumen’s Talk-Back Actually Does

Lumen 1.13.0 added two-way audio talk-back as a beta feature, off by default behind a Settings toggle. When you enable it and open a compatible camera’s live view on iPhone, a push-to-talk button appears in the camera controls. Hold the button, speak into your iPhone’s mic, release. Your voice travels through go2rtc’s audio back-channel to the camera’s speaker. Someone standing in front of your camera hears you.

The feature works on iPhone, iPad, and Mac. I’ve been running it for a few weeks on iPhone. My most-used scenario: a delivery driver pulling up while I’m upstairs. I watch on Lumen, see them look uncertain about where to leave the package, tap the talk button, and say “behind the planter on the left.” Done. Before this, I either ran downstairs or hoped for the best.

Which Cameras Support It

Not every camera with a speaker exposes a proper audio back-channel. The ones that generally do:

  • Reolink cameras with built-in speakers: E1 series, RLC-810A, TrackMix, Duo series, and most models that list “two-way audio” in their specs.
  • TP-Link Tapo: C200, C210, C310, C320WS — basically any Tapo cam with a speaker.
  • Amcrest IP cameras in the IP5M and IP8M families, and anything listing “two-way audio” in the spec sheet.
  • Dahua and Hikvision: most models with a visible speaker grille on the front.

The technical requirement is that the camera exposes an RTSP audio back-channel or WebRTC audio input — go2rtc handles the protocol negotiation automatically for supported devices. If you’re not sure about yours, check the spec sheet for “two-way audio” or “built-in speaker.” It’s a standard feature on anything designed to double as a doorbell, baby monitor, or indoor cam.

Enabling It in Lumen

It’s off by default. In Lumen, go to Settings → select your Frigate server → tap the camera → enable Two-Way Audio. Then open that camera’s live view and the push-to-talk button appears alongside the other controls. Hold to talk, release to let the camera pick up again.

Because this is a beta, expect it to feel less polished than the rest of Lumen. Latency varies by your network setup. Over a local connection it’s fast enough to feel like a real conversation — you’ll hear the response without a noticeable gap. Over a Cloudflare tunnel or reverse proxy, expect 0.5–1 second of added delay, which is workable for short interactions but awkward for a back-and-forth conversation.

Scenarios Where It Actually Helps

The delivery situation is the obvious one, but it’s come up in other ways too.

I have contractors in the backyard a few times a year. Being able to ask a quick question or confirm a detail from my desk upstairs — without putting shoes on, walking down, interrupting what I was doing — is consistently useful.

Unexpected visitors at a gate I can see on camera but can’t reach from inside the house. I can have a short conversation through Lumen before deciding whether to go to the door. And yes, I’ve used it to deter the neighbor’s dog. An authoritative “hey” from the camera speaker is apparently convincing.

Two-way audio isn’t a replacement for a dedicated video doorbell if that’s your primary use case. A Reolink Doorbell or any dedicated intercom unit will have lower latency and a simpler setup. But if you already have Frigate running cameras that happen to have speakers, this is a capability you’ve technically owned for years and never been able to use from your phone.

The Part That Surprised Me

I expected to use talk-back occasionally. I use it most days now. The gap between “I can see this” and “I can do something about it” used to require physically being there. For a specific set of situations — someone at the door, someone in the yard — a voice is enough. You don’t need to be there. You just need a speaker on the camera and a button in the app.

If your Frigate cameras have speakers, enable the beta and try it. Worst case: it’s a little rough and you turn it off. Best case: you stop running downstairs for deliveries.
