Settings reference

Per-source properties live on the source, plugin-wide settings under Tools, and anything about the phone in the app.

Source properties (LensLink Camera)#

Right-click the source → Properties.

Property	What it does
Status	Read-only: the current stage, plus device, format and measured latency while connected. Status table.
Connection	Wi-Fi — enter the phone's IP or USB cable.
Phone	Wi-Fi only. Pick a phone by name, or type its IP.
USB device	USB only. Auto, or a specific device so the same phone always feeds this source.
Low latency mode	Render the newest frame immediately rather than smoothing. On by default.
Hardware decoding (GPU)	Decode on the GPU, falling back to software automatically. On by default.
Disconnect when this source isn't shown anywhere	Hidden (eye off, or in no visible scene, preview or projector) means disconnected, so the phone stops encoding — saving battery and freeing it for another source. Reconnects when shown; with auto-start on, it also stops and starts the camera.
Start the phone's camera automatically when it's ready	Remote start, when the app is open and idle. On by default.
Start / Stop camera on the phone	Buttons: do it now, once.
Lip-sync audio source	Your real microphone — the one to align.
Automatically delay that audio source…	Applies the measured camera latency to that audio source.
Auto-calibrate	Measure the offset from the phone's mic reference. Needs Auto lip-sync reference on in the app; ignores the manual latency below.
Auto video delay for slow mics	Delays the video instead, for mics slower than the stream.
Audio device's own latency	Manual mode only. Subtracted from the delay.

A LensLink Screen source has the connection, decoding and diagnostics properties only.

Plugin settings (Tools → LensLink Settings)#

One value for the whole plugin, never duplicated per source.

Setting	What it does
GPU decode pipeline (beta)	Keeps decoded video on the graphics card. All sources, after an OBS restart; falls back per source where textures can't be shared. Details.
Browser control panel	Serves the panel on loopback. On by default.
Panel port	Default `9980`.
Verbose diagnostics in the OBS log	Much more per-connection detail. On to reproduce a bug, off afterwards.
Dump received video to disk	Writes the raw stream so a decode problem can be reproduced off-device.
Record pipeline benchmark	A log summary every 5 seconds and one CSV sample per second, in the plugin's config folder.

App options#

The Options row at the bottom of the Setup screen.

Option	What it does
Remote start from OBS	Lets OBS start the camera while the app is open and idle. The phone stays awake waiting; locking it or leaving the app ends standby.
Idle view	What the Live screen becomes 10 seconds after your last touch. Standard keeps the controls; Clean feed shows only the picture; Dim screen blanks it, drops the brightness and shows the battery level — and alone also dims remote-start standby, a minute in. Any tap restores the controls.
Allow system video effects	Experimental: lets iOS lower the capture frame rate, which Control Center's effects may require. Applies when the camera next starts.
Tally light	Colors, priority order, per-status off switches, and which statuses pulse. See below.
Presets	Saved camera looks and the switch for applying them. Presets.
Send phone mic to OBS	Makes the phone the camera source's audio — a wireless mic.
Auto lip-sync reference	Sends the mic as a timing reference only; never heard. Mutually exclusive with the row above.
Camera diagnostics	Every format this device has, and which support Control Center effects, 10-bit HDR or Apple Log. Paste it into a bug report.
Check broadcast link	Verifies the screen-mirror extension is alive, independent of OBS. Run it while broadcasting.

Tally light#

The colored border around the Live screen. The highest status that is true and has a color wins; setting one to Off lets lower ones show through.

Status	Default	Meaning
On air	Red, 6 pt	In OBS's live output.
In preview	Amber, 4 pt	Visible in OBS, but not live.
Connection lost	Off	Streaming, but the link to OBS dropped.
Calibrating lip-sync	Off	Measuring or re-measuring.
Lip-sync locked	Off	Calibration locked on.
Low battery	Off	Low Power Mode, or 20% and below, while unplugged.

Colors: red, amber, green, blue, purple, white, off. On air keeps the heaviest stroke whatever its color. Any lit status can pulse instead of holding steady (off by default), and Reduce Motion turns every pulse into a steady border of the same color — less motion, never less warning.

Where a setting is not#

Resolution, frame rate, codec and color live on the phone, since only it knows what its cameras can do. Other surfaces can change them mid-stream, but the app owns the list.
Global switches are never repeated per source. If it isn't on the source, it's under Tools → LensLink Settings.
Anything settable from more than one place reads the same cached state, so the three surfaces never disagree.
