Buying Guide
- What resolution do you need? If you frequently share fine print or technical diagrams, prioritize models with 4K/8MP sensors (e.g., S2-4K, TreasLin). For simple board work, 1080p options may suffice (HUE HD Pro).
- How portable must it be? Foldable or compact models are ideal for teachers who travel between classrooms or work from home (e.g., PAKOTOO or OKIOCAM variants).
- Do you need image inversion or mirroring? Many cameras offer left-right or up-down mirroring; this is crucial for presenting pages oriented in portrait vs. landscape formats (PAKOTOO, kitchbai-style devices).
- Lighting and focus controls: Look for models with adjustable LED lighting and quick autofocus to handle dim rooms or different paper textures (TreasLin, kitchbai-style options).
- Platform compatibility: Ensure the device supports your operating system (Windows, macOS, Chrome OS, Linux) and conferencing apps (Zoom, Google Meet, Teams). Some devices advertise broader compatibility (TreasLin, OKIOLABS S2-4K).
- Connectivity: USB 2.0/3.0 is common; HDMI is less frequent in student-facing setups. USB cameras are generally easier to deploy in standard classrooms.
