UGREEN CM831 Webcam stock is in at Mascom International for KSh 5,000, a 4K Ultra HD camera with autofocus, two microphones and a sliding privacy cover. Every unit is brand new and sealed. An 8MP sensor records 4K at 30 frames per second, or switches to 1080p at 60 frames per second for smoother motion. Phase detection autofocus keeps your face in focus from about 10 centimetres to 5 metres away. A USB adapter in the box lets the UGREEN CM831 Webcam plug into either a USB-A or USB-C port. You can see it working at our shop in the Old Mutual Building on Kimathi Street, Nairobi CBD.
Designed for lawyers, accountants, university students and sales teams across Kenya, the UGREEN CM831 Webcam fixes a common problem: laptop cameras that blur faces and turn a room grey. Many business laptops still carry a 720p camera, which looks soft on a large meeting-room screen. This camera sits on top of your monitor, laptop or TV and gives Zoom, Microsoft Teams and Google Meet a far cleaner picture. Advocates joining virtual court sessions, Strathmore and USIU students presenting online, and creators filming tutorials all get a clearer image. The UGREEN CM831 Webcam does this without a separate camera rig or capture card.
Where most Nairobi electronics shops sell unbranded webcams with no warranty, Mascom International stocks genuine UGREEN units backed by written 6-month cover. Among the UGREEN webcams on our shelves, the UGREEN CM831 Webcam costs KSh 500 less than the 2K UGREEN CM778 Webcam and KSh 2,000 more than the 1080p UGREEN CM678 Webcam. Customers across Nairobi tell us they want to test a webcam on their own laptop before paying, and you are welcome to do exactly that here. Prefer to stay at your desk? We deliver across all 47 counties, and you pay only when the camera arrives.
Common Questions About the UGREEN CM831 Webcam
How much is the UGREEN CM831 Webcam in Kenya?
The UGREEN CM831 Webcam costs KSh 5,000, brand new and sealed, at Mascom International in Nairobi CBD. That price covers the camera, its adapter for USB-A and USB-C ports, and a 6-month warranty against manufacturing defects. Delivery is pay-on-arrival, so you pay by cash or M-Pesa only once the camera is in your hands. It sits KSh 500 below the 2K UGREEN CM778 Webcam at KSh 5,500, and KSh 2,000 above the 1080p UGREEN CM678 Webcam at KSh 3,000.
Should I buy the UGREEN CM831 Webcam or the UGREEN CM778 Webcam?
The UGREEN CM831 Webcam records 4K at 30 frames per second for KSh 5,000, while the UGREEN CM778 Webcam records 2K QHD at 2560x1440 for KSh 5,500. Both have a built-in microphone and autofocus, and the UGREEN CM778 Webcam connects over USB 2.0. The 4K model gives you more pixels to crop and zoom in recordings, which matters for tutorials and product videos. Pick the UGREEN CM831 Webcam for higher resolution at the lower price, or visit our store to compare both pictures side by side first.
Will the UGREEN CM831 Webcam keep working during a KPLC power cut?
Yes, the UGREEN CM831 Webcam draws power from your laptop's USB port, so it keeps running as long as your laptop battery lasts during a KPLC outage. It needs no separate plug or socket. Your internet is the weak point instead: if your fibre router goes off, switch to a Safaricom or Airtel Kenya hotspot on your phone. Zoom and Teams lower picture quality automatically on a slower mobile connection, so the call carries on even when the 4K detail drops.
Who should buy the UGREEN CM831 Webcam, and who should skip it?
The UGREEN CM831 Webcam suits people who appear on camera daily, such as advocates in virtual hearings, consultants pitching clients and teachers running online classes. Content creators recording tutorials will use the 4K mode most. Skip it if you join only one or two short calls a week and want to spend less; the 1080p UGREEN CM678 Webcam at KSh 3,000 covers basic video calls well. Streamers who need more than 60 frames per second for fast gaming footage should look at a dedicated streaming camera instead.
Does the UGREEN CM831 Webcam need drivers on Windows or Mac?
No, the UGREEN CM831 Webcam is plug-and-play on Windows 7, 8, 10 and later, macOS 10.6 and later, Linux, and Android. Plug it into a USB port, open Zoom, Teams, Google Meet or your camera app, and select it as the video source. There is no driver download and no install disc. The included adapter means it fits newer laptops with only USB-C ports as well as older desktops with USB-A ports. On Android, support depends on the phone or tablet accepting USB cameras.
How good are the microphones on the UGREEN CM831 Webcam?
The UGREEN CM831 Webcam has two built-in microphones that pick up your voice from about 5 metres away. That range covers one person at a desk or a small team seated around a meeting table in a Westlands or Upper Hill office. In a busy open-plan office, sit closer to the camera for the clearest result. For podcasts or voice-over work, a dedicated USB microphone still gives richer sound, but for daily calls the built-in pair saves you buying a separate headset.
Does the UGREEN CM831 Webcam handle dim rooms and changing light?
The UGREEN CM831 Webcam uses an 8MP sensor with automatic exposure, which adjusts brightness as the light in your room changes. That helps on overcast afternoons or in an office lit only by overhead tubes. Phase detection autofocus keeps your face in focus as you lean in to show a document or move back towards a whiteboard. For the best picture, face a window or a desk lamp rather than sitting with a bright window behind you, which darkens your face on any camera.
Is the UGREEN CM831 Webcam worth it for recording YouTube or TikTok content?
Yes, for talking-head videos, tutorials and product reviews filmed at a desk, the UGREEN CM831 Webcam is a practical starting point at KSh 5,000. It records 4K at 30 frames per second, or 1080p at 60 frames per second when you want smoother movement. Plan your storage: one hour of 4K footage takes about 21GB on your laptop. Many creators begin with a webcam like this before moving to a mirrorless camera, which costs many times more and needs extra capture gear.
Technical Specifications
Image Sensor and Video Quality
- 8MP CMOS sensor — eight million pixels capture fine detail in faces, documents and products held up to the lens.
- 4K Ultra HD at 30 frames per second — four times the pixels of 1080p, useful for recordings you plan to crop later.
- 1080p Full HD at 60 frames per second — smoother movement for demonstrations, whiteboard sessions and hand gestures on camera.
- Automatic exposure — the camera adjusts brightness on its own as daylight fades or office lights switch on and off.
- Low-light sensitivity — the sensor is tuned to gather more light in dim rooms, cutting the grainy look of basic laptop cameras.
- About 21GB per hour of 4K recording, or about 8GB per hour at 1080p — plan laptop storage for long lessons.
Autofocus and Microphones
- Phase detection autofocus, or PDAF — measures distance directly, so focus locks onto your face quickly instead of hunting back and forth.
- Focus range of about 10 centimetres to 5 metres — hold a contract or business card close and the text stays readable.
- Subject tracking — focus follows you as you lean forward, sit back or step towards a whiteboard behind your desk.
- Dual built-in microphones — two mics pick up your voice without a separate headset during calls, interviews and online classes.
- Voice pickup up to about 5 metres — covers a single speaker at a desk or a small group around a meeting table.
Compatibility and Software
- Plug-and-play USB connection — no drivers to download, because the computer recognises it as a standard camera straight away.
- Windows 7, 8, 10 and later — works on office desktops and personal laptops running any of these Windows versions.
- macOS 10.6 and later — works on MacBook Air, MacBook Pro and iMac computers with no extra software to install.
- Linux and Android support — suits developers working on Ubuntu and Android tablets or phones that accept USB cameras.
- Zoom, Microsoft Teams, Google Meet and OBS Studio — choose the camera as your video source inside each app's settings menu.
- USB-A and USB-C through the included adapter — one camera serves older desktops and newer slim laptops with only USB-C ports.
Build and Mounting
- Built-in sliding privacy cover — physically blocks the lens when you are off a call, so nobody sees in by accident.
- Monitor, laptop and TV placement — the mount sits on top of a screen, keeping the lens close to eye level.
- Tripod use — mount it on a tripod when you want to film from the side or from a different height.
- Powered over USB — draws power from the computer, so there is no extra plug to fit into a crowded socket.
- Dust care — wipe the lens with a dry microfibre cloth weekly, since dust settles fast on desks near open windows.
- Black finish — blends in with most monitors, laptops and TV frames in a home office or meeting room.
Inclusions
- UGREEN CM831 Webcam unit — the camera itself, with its sliding privacy cover built into the front.
- USB-A and USB-C adapter — lets the same camera move between an office desktop and a USB-C laptop at home.
- Driver-free setup — nothing to install, no software disc and no account sign-up before your first call.
- 6-month Mascom International warranty — covers manufacturing defects, with claims handled at our Nairobi CBD service desk.
- Brand new and sealed — genuine UGREEN retail packaging, opened only when you ask to test the camera in store.
