Power
Max Power Draw
25 W
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.

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

LED Type
IR
Min. Illumination
Minimum lux for clear image. Lower = better in dark environments. 0 lux = IR only.
0.001 lx
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.
CMOS
Resolution (MP)
Higher megapixels = more detail. 12MP+ is sufficient for most uses.
4 MP
Video Recording
Yes
Wide Dynamic Range (WDR)
Captures detail in both bright and dark areas simultaneously.
Yes
Optical Zoom
Optical zoom uses lens movement (quality preserved). Digital zoom crops (loses quality).
Yes
Backlight Compensation (BLC)
BLC prevents silhouetting when subject is backlit.
Yes
Bitrate Control
VBR: variable bitrate (better quality). CBR: constant (predictable bandwidth).
Constant Bit Rate (CBR), Variable Bit Rate (VBR)
Detection Distance
100 m
Dynamic Range
120 dB
Highlight Compensation (HLC)
HLC reduces overexposed bright spots (headlights, floodlights) in the frame.

Signal-to-Noise Ratio
Higher SNR (dB) = cleaner image with less grain/noise. 50+ dB is good.
55 dB
White Balance
Corrects colour cast under different lighting. ATW = auto-tracking white balance.
