Webcams have become essential devices in the era of remote work and online meetings. Whether it's Zoom, Google Meet, Microsoft Teams, or livestreaming, webcam quality directly affects your professional image in front of colleagues and clients. Built-in laptop cameras usually deliver poor image quality — lacking detail, poor in low light, and inaccurate colors. An external webcam can dramatically improve your video call quality.
With webcams, you don't need to spend a fortune — a good 1080p webcam can cost as little as 500K to 1.5 million VND. This guide will help you understand the specs and choose the right webcam for your needs.
What to Know When Buying a Webcam
Five main factors: resolution, frame rate (fps), focus capability, built-in microphone, and field of view (FOV).
Resolution — 1080p (Full HD) is the minimum standard for 2025. 720p still works but looks blurrier and lacks detail. 4K webcams deliver the sharpest image but require high bandwidth and cost more. However, most Zoom/Teams calls only support up to 1080p, so 4K is often overkill.
Frame rate — 30fps is the standard for video calls. 60fps provides smoother quality, especially when you move around a lot or livestream games. Some premium webcams support 1080p@60fps or 4K@30fps.
Focus — auto-focus keeps you sharp even when moving. Fixed-focus is cheaper but less flexible. Some webcams have dual microphones with AI noise cancellation — very useful if you work in a noisy environment.

Types of Webcams
Basic 1080p Webcam
Affordable, decent quality for daily meetings. Usually has fixed-focus or basic auto-focus, single mic. Suitable for students and office workers. Examples: Logitech C270 (720p) — lowest budget, Logitech C920S — 1080p standard, Microsoft Modern Webcam.
Premium 1080p Webcam
Superior image quality, fast auto-focus, dual noise-cancelling mics, smart light adjustment. Suitable for professionals, freelancers, content creators. Examples: Logitech Brio 305, Razer Kiyo Pro, Anker PowerConf C200.
4K Webcam
4K resolution, large sensor, wide field of view, multiple setup modes. Suitable for livestreaming and professional video recording. Requires a powerful computer and USB 3.0 connection. Examples: Logitech Brio 4K, Dell UltraSharp Webcam, Insta360 Link (with gimbal).
Webcam for Livestreaming / Content Creators
Professional design, built-in ring light or gimbal, remote control. Examples: Razer Kiyo Pro Ultra, Elgato Facecam, Insta360 Link (AI motion tracking).
Laptop cameras usually have small sensors, poor quality especially in low light. External webcams have larger sensors, better lenses, and often include features like auto-focus, HDR, and privacy shutter. The difference between a 1 million VND webcam and a laptop camera is very noticeable.
Webcam vs DSLR/Mirrorless Camera
Cameras deliver vastly superior image quality compared to webcams, especially with interchangeable lenses and large sensors. However, using a camera as a webcam requires a capture card (or software like Elgato Cam Link), which is complicated and much more expensive. Webcams are plug-and-play — just connect and go.
Webcam vs Smartphone
Many people use their smartphone as a webcam via apps (EpocCam, DroidCam). Smartphone cameras are usually better than similarly priced webcams, but it's inconvenient because it ties up your phone, heats up easily, and isn't stable for long calls. A dedicated webcam is more reliable.
Common Mistakes When Buying
Buying a 4K webcam when you don't need it — 4K webcams cost much more but most meeting apps only display 1080p. The price difference is better spent on lighting or a better microphone.
Forgetting to check FOV — Too narrow a field of view (65°) makes you look like you're in a box. Too wide (120°) makes the background messy. 78-90° is ideal.
Ignoring microphone quality — A webcam with a good mic (dual + noise cancellation) is important if you don't have a separate mic. Poor audio will ruin a call no matter how good the video looks.
Not checking low-light performance — If your workspace is dimly lit, choose a webcam with HDR or a large sensor (like the Razer Kiyo Pro).
Buying a webcam without a privacy shutter — A camera cover is essential for security. If the webcam doesn't have one, you'll need tape or a separate cover.
Forgetting to check software compatibility — Some webcams have customization software (Logitech G Hub, Razer Synapse). If using Linux, check drivers (UVC compatible) first.
Conclusion
A webcam is a small device but has a big impact on your professional image during online meetings. The Logitech C920S (around 700-900K VND) is the best choice for most users: 1080p, auto-focus, dual mic, privacy shutter. If you need higher quality, the Logitech Brio 305 (around 2 million VND) with HDR and AI noise-cancelling mic is a worthwhile upgrade. For streamers, the Elgato Facecam or Razer Kiyo Pro Ultra are professional choices.
Advice: invest in lighting (ring light or key light) before buying a 4K webcam. A 1080p webcam with good lighting will look better than a 4K webcam in a dark room.
