Questions before you install.
- What do I need?
- A Mac with macOS 14 Sonoma or later (Apple Silicon or Intel), an iPhone with the free Blackmagic Camera app, and both on the same Wi‑Fi network.
- Does it record on my Mac?
- No. Recording stays on the iPhone, in the quality you chose there. The Mac is the monitor and the remote control.
- How far behind real time is the video?
- About 0.3 s glass to glass, most of it on the iPhone side. Enough to check framing, focus and sound while you talk.
- What does it change on my iPhone?
- It adds a streaming platform called “Mac Monitor SRT” to Blackmagic Camera and makes it active while bmonitor is open. When you quit, it stops the stream and restores the platform you had before.
- Can I use more than one iPhone?
- One at a time. If there's more than one on the network, bmonitor asks which one to use.
- Is it finished?
- It's a public beta. It works every day on the author's setup, but it was tested on one Mac and one iPhone, so expect rough edges and report what you find.
- Is it made by Blackmagic Design?
- No. bmonitor is an independent project that talks to Blackmagic Camera through its documented remote API and live stream.
- Is it free?
- Yes. Free and open source (MIT), with no ads, no account and no paid version. It collects nothing and only talks to the iPhone on your network. If it's useful to you, a coffee is welcome and never required.
Free. Open source.
Built for the Mac.
