ZestCam: 4K Streaming Webcam

ZestCam turns your iPhone into a professional camera for OBS. Stream a clean 4K picture over Wi‑Fi with SRT, or send it over USB and HDMI. No watermark and no on-screen controls in your shot.

TWO WAYS TO CONNECT
• Wireless SRT: stream over your local Wi‑Fi straight into an OBS Media Source. Encrypted, low latency, no capture card needed.
• USB and HDMI: connect the iPhone to your computer or a capture card. The screen becomes a clean full-screen feed and the controls hide themselves. On HDMI, the phone's own screen dims.

PRO IMAGE QUALITY
• Up to 4K at 60 fps, plus 4K30, 1080p60 and 1080p30, depending on your iPhone.
• Picks the best camera format automatically, with video stabilization.
• H.264 or HEVC. HEVC uses about a third less bandwidth at the same quality.
• The picture follows how you hold the phone, in landscape or portrait.

AUDIO
• Turn on the microphone to send sound to OBS along with the picture.

CAMERA CONTROLS
• Tap to focus and expose. Long-press to lock AE/AF. Slide to adjust exposure.
• Pinch to zoom up to 5×, moving smoothly between the ultra-wide and wide lenses.
• Switch between the front and back cameras in one tap.

BUILT TO STAY LIVE
• Reconnects automatically after short network drops.
• Lowers the bitrate when Wi‑Fi gets busy and raises it again when it clears.
• Brings the picture back after calls and other interruptions.
• Steps down from 4K to 1080p if the phone gets too hot, so the feed keeps going.
• Keeps the screen awake while you're live.
• Shows bitrate, frame rate, latency and packet loss on screen.
