Overview
The Hikvision DS-2TB1217-3/QA is a bi‑spectrum (thermal + optical) thermographic turret camera designed for indoor temperature screening and security. It pairs a 160×120 VOx thermal module with a 4 MP visible sensor to provide concurrent thermal and optical imaging, picture‑in‑picture/bi‑spectrum fusion and temperature‑exception alarm functions.

• Thermal sensor: 160 × 120 VOx uncooled FPA, NETD < 40 mK.
• Optical sensor: 4 MP (2688 × 1520) 1/2.7" progressive CMOS for identification and context.
• Temperature screening: built‑in measurement and alarm (typical screening range 30–45 °C; screening accuracy ±0.5 °C as published by manufacturer).
• Connectivity & storage: 10/100 Mbps Ethernet (RJ‑45), PoE (802.3af), 12 V DC input, on‑board MicroSD (manufacturer states up to 256 GB); H.264/H.265 compression.
• Alarm: audible and visual/strobe alarm support for temperature exceptions.

Use cases: controlled indoor entrance screening, security environments where thermal detection with visible context is required, and locations needing automated temperature‑exception alerts.

Important installation notes: Temperature screening is environment sensitive — accuracy requires manufacturer‑recommended mounting, controlled indoor/windless environment and calibration procedures. Refer to the Hikvision datasheet and user manual for detailed installation, calibration and operating guidance. Non‑compliant installation may reduce measurement accuracy.
