Power
Typical Power Draw
Typical board power (W) is the power draw under normal gaming load. Use it to estimate electricity cost and to size cooling. Peak transient spikes can be 20-30 percent higher, which is why PSU recommendations leave a buffer.

Shutter Speed
Exposure time range. Faster shutter reduces motion blur in bright scenes.

Frame Rate
Frames per second (fps). 30 fps = standard; 60 fps = smoother video.

IR
Min. Illumination
Minimum lux for clear image. Lower = better in dark environments. 0 lux = IR only.

Sensor Size
Larger sensor = better low-light performance. Full-frame > APS-C > MFT > 1/2.8".
1/2.8
Progressive Scan
Captures full frames vs interlaced (alternating lines). Reduces motion blur.
Yes
Sensor Type
CMOS: most cameras today. CCD: older, higher quality. BSI: better low-light.
