Wex Photo Video, one of the UK’s largest camera retailers, produced a concise buyer’s guide to the two YoloCam models. Rather than a hands-on opinion piece, it is a structured explanation of what the YoloCam S3 and YoloCam S7 have in common and where they diverge, aimed at anyone choosing between them for live streams, conference calls or content creation. This article follows that structure.
What the S3 and S7 Share
Both are professional webcams designed for image quality comparable to mirrorless and DSLR cameras, and both are plug-and-play: connect over USB and a PC or Mac recognizes them as a webcam immediately for streaming or calls.
Both capture up to 4K, which improves overall picture quality and enables a 4x digital zoom controlled from the YoloLiv Compose app. Wex highlighted the hotkey zoom presets as a creative tool for live use, letting you jump between framings during a stream.
Both offer ultra-fast autofocus with four modes in Compose: continuous, single, face detect and manual. The on-screen face-tracking box shows the autofocus following you in real time, which Wex described as giving confidence that focus is always locked.
YoloCam S3: Key Features
The S3 is the smaller of the two. It uses a 1/1.3-inch sensor with a fixed, non-interchangeable 24mm f/1.85 lens, giving a wide field of view suited to typical webcam positioning on a monitor.
It ships with a magnetic mounting plate that sits on top of a display. Wex noted the magnet is strong enough that the camera should not fall if knocked, and the camera can be positioned manually for horizontal or vertical video. The mount also has a 1/4-inch screw hole for tripods.
Power and the webcam connection run through a single USB-C to USB 3 cable, which keeps the setup simple.
YoloCam S7: Key Features
The S7’s size and weight are closer to a mirrorless camera, with what Wex called a robust and aesthetically pleasing design.
The sensor is a 4/3-inch Micro Four Thirds unit with an interchangeable lens mount, offering far more creative control. For the video Wex fitted a Panasonic Lumix 12-35mm f/2.8, described as a good all-rounder for both wide and tighter looks, while noting buyers can choose any MFT lens for a specific look.
Autofocus is time-of-flight, which Wex described as far more accurate than contrast-based systems. The important caveat: pair the S7 with autofocus-compatible lenses. Dual ISO makes it strong in low light and other varied lighting.
Connectivity is more extensive. The S7 connects as a webcam via a USB-C output but takes power separately through a neighboring USB-C input, which can come from another computer USB port or a mains adapter. An HDMI output makes it a natural pairing with external recorders and switchers, including any YoloBox. A 3.5mm microphone input lets you route audio through the camera so video and audio arrive over one USB line.
Mounting requires a tripod or stand via the 1/4-inch thread on the bottom, and Wex pointed out that an L-bracket may be needed to set it up for horizontal video.
Which One Should You Choose?
Wex’s summary: both cameras “perform very well” and suit anyone who values professional picture quality for live streams, conference calls or content creation. The S3 is the compact, single-cable, monitor-mounted option with a fixed wide lens. The S7 is the larger, lens-swappable, HDMI-equipped option for creators who want mirrorless-style control and integration with switchers.
