YoloLiv YoloCam S3

4K Streaming Webcam with DSLR-Level Image Quality

This 4K AI-powered webcam is built for creators who want mirrorless-camera image quality from a single USB-C cable. It centers on what the manufacturer calls the largest CMOS sensor ever fitted into a webcam — a 1/1.28" chip with an f/1.85 aperture — producing real optical bokeh, true HDR detail, and uncompressed 4K at 30 fps straight out of the box, making it the right choice for live streamers, podcasters, and content creators who need DSLR-grade visuals without the bulk of a mirrorless rig.

What Sets This Webcam Apart

The patented Picasso Resolve engine lets users perform real-time live color grading on the camera feed during streams — a workflow normally reserved for post-production in DaVinci Resolve. The all-aluminum body with an expansive heat-dissipating structure is rated for non-stop 24/7 streaming, with the surface running warm as a deliberate cooling signal rather than a fault.

Sensor and Image Quality

This model uses a 1/1.28" CMOS chip — substantially larger than the typical 1/3" sensors in competing webcams — combined with an f/1.85 aperture and 24 mm equivalent focal length for real optical background separation and clean low-light performance without software simulation.

• Sensor Size: 1/1.28" CMOS — the largest sensor ever fitted into a webcam body, capturing more light than typical 1/3" webcam chips
• Aperture: f/1.85 — fast lens for shallow depth of field

Video Resolution and Autofocus

The YoloCam S3 streams uncompressed 4K at 30 fps or 1080p at 60 fps, with PDAF phase-detection autofocus locking onto the subject in roughly 0.3 seconds.

• Max Resolution: 4K @ 30 fps
• Autofocus: PDAF — phase-detection with 0.3 s lock speed and face-tracking, plus customizable focus zones for multi-subject scenes

Connectivity, Mounting and Software

This webcam connects over USB-C (with a USB-C to USB-A adapter included) and ships with a magnetic mount plus a 1/4"-20 thread for tripod use, while the free YoloLiv Compose software exposes manual exposure, ISO, shutter speed, white balance, and the Picasso Resolve color-grading wheel.

• Connectivity: USB-C
• Mounting: Magnetic mount + 1/4"-20 thread — fits monitors, laptops, and tripods, with the 187 g body staying planted on the included stand

Who This Webcam Is Built For

This model is the right choice for live streamers, podcasters, YouTubers, and remote-work professionals who need DSLR-grade image quality from a single USB-C cable. Wedding and funeral videographers benefit from cropping multiple angles with clarity and focus, while corporate presenters get the clean look of a mirrorless camera without the setup complexity. Creators who stream on TikTok, YouTube, Twitch, OBS, Teams, or Zoom will find native compatibility across the major platforms.

YoloLiv — From Live-Streaming Pioneer to Webcam Disruptor

YoloLiv built its reputation on the YoloBox family of all-in-one live-streaming switchers used by churches, sports broadcasters, and event videographers worldwide, and this webcam extends that live-production DNA into a single USB device — bringing broadcast-grade imaging philosophy to creators who don't need a full switcher setup and marking YoloLiv's move into the global creator-webcam segment.
