About 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. SET UP IN A MINUTE 1. Enter your computer's IP address. 2. Copy the link, share it, or show it as a QR code, then paste it into an OBS Media Source. 3. Tap Start streaming. A built-in guide walks you through it, and every error tells you what went wrong and how to fix it. GREAT FOR Live streaming, online classes, church services, meetings, podcasts, tutorials, product demos and multi-camera setups. Works with OBS Studio on Mac and Windows.
