Q&A
Q: What makes this better than a single-lens counter?
Dual-lens cameras provide 3D stereo vision, improving accuracy, especially in busy entrances with overlapping people.
Q: Can this camera tell how long someone stayed?
Yes. You can configure "stay time" alerts for loitering or queue areas.
Q: Is it weatherproof for outdoor mounting?
Yes, it’s IP67 rated, but there’s no IK rating, so it's best under eaves or canopies.
Q: Can I view the heat map on mobile?
Heat maps are best viewed using SmartPSS or CMS software on a PC.
Q: Does this camera support face detection?
No. This camera is optimized for people counting only, not face capture.
Q: Can I mount this on a ceiling or wall?
Yes. The included quick-mount board makes both types of mounting easy.
