Introduction to the Hikvision DS-2TD2167-35/PY
TheHikvision DS-2TD2167-35/PYis a rugged thermal network bullet camera engineered for long-range perimeter protection, temperature anomaly detection and fire-prevention applications. Built around a 640 × 512 VOx uncooled thermal sensor with a fixed 35 mm lens, this camera emphasises reliable detection at distance, automated analytic alarms and resilience to harsh outdoor environments (IP67, IK10 and TVS lightning protection). It’s offered as a purpose-built solution for airports, rail sites, power plants, prisons, vehicle depots and other critical infrastructure where early detection and low false positives are vital.

- Built-in perimeter analytics (line crossing, intrusion, region entrance/exit) and temperature-exception & fire pre-alarm capabilities.
- Designed for harsh environments: IP67 ingress protection, IK10 impact rating and TVS 6000 V lightning protection.
- Flexible power and recording options: PoE (802.3af), 12 VDC input, microSD up to 256 GB, NAS and compatibility with ONVIF and Hikvision SDKs.
Detailed specifications and benefits
The DS-2TD2167-35/PY is more than its headline sensor; its combination of optics, analytics and ruggedisation make it a practical tool for security teams who need reliable detection day or night and under challenging conditions.
- Resolution:640 × 512 pixels — a higher resolution thermal array than the common 320 × 240 modules, delivering finer thermal detail and improved detection at greater distances.
- Detector:VOx uncooled FPA with 17 µm pixel pitch and NETD ≤ 35 mK (at 25 °C, F# = 1.1), offering good sensitivity to small temperature differences.
- Lens & focus:Fixed 35 mm lens, IFOV 0.49 mrad and a minimum focus of 30 m; aperture F1.0. The narrower field of view concentrates the sensor on long-range corridors or perimeters to maximise detection distances.
Benefit: higher-resolution thermal imaging and a long-focus lens translate into real-world detection distances — manufacturer DRI figures indicate human detection in the order of ~1,029 m and vehicle detection in the multiple-kilometer range, making this camera suitable for expansive perimeters.
- Perimeter VCA: line crossing, intrusion and region entrance/exit rules (up to 8 rules).
- Temperature alarms: built-in temperature-exception monitoring and fire pre-alarm rules; measurement rules support up to 21 rules (10 points, 10 areas, 1 line).
- Image modes: white hot / black hot and target coloration to accentuate thermal signatures.
Benefit: combining perimeter analytics with temperature-exception logic allows operators to detect both intrusions and thermal anomalies (e.g., hotspots that may indicate equipment faults or early-stage fires) and trigger automated alerts, reducing response times and false alerts when correctly configured.
- Video compression: H.265+/H.265/H.264+/H.264, MJPEG on sub-streams; supports main/sub/third streams including native 640 × 512.
- Storage: microSD up to 256 GB, NAS (NFS, SMB/CIFS) and ANR support for network outages.
- Protocols & compatibility: IPv4/IPv6, HTTPS, 802.1x, ONVIF and Hikvision SDK.
Benefit: efficient compression and flexible recording options reduce bandwidth and storage cost while maintaining high-quality thermal footage for review and evidence retention. ONVIF compatibility eases integration with a wide range of VMS platforms and third-party systems.
- IP67 ingress rating and IK10 impact rating for exposed sites; operating temperature −40 °C to 65 °C.
- TVS 6000 V lightning/surge protection and options for PoE (802.3af, class 3) or 12 VDC supply.
- Alarm I/O (2 inputs, 2 relay outputs), RS-485 serial, RJ45 10/100 Mbps network port and 3.5 mm mic/line input.
Benefit: robust mechanical and electrical protection makes the camera suitable for coastal, industrial or remote outdoor installations where weather, impact and electrical surges are common risks.
Use cases and scenarios where the camera excels
The DS-2TD2167-35/PY is designed for situations that prioritise long-range detection, thermal visibility and reliable alarm generation. Typical deployments include:
- Critical infrastructure perimeter protection:airports, energy facilities, water treatment plants and substations can use long-range thermal detection to monitor large fence lines and remote approaches, alerting security teams to potential intrusions before close contact.
- Transport hubs and rail yards:consistent detection of people and vehicles across sprawling sites, especially in low-light or visually obscured conditions where visible-light cameras struggle.
- Vehicle depots and storage yards:monitor vehicle movement and detect unauthorized access across large areas; thermal imaging can detect running engines or heat signatures not visible in darkness.
- Fire pre-alarm and temperature monitoring:early detection of hotspots on perimeters, storage areas or outdoor equipment can trigger pre-alarms that reduce response time and potential damage.
- Coastal and corrosive environments:the anti-corrosion body, IP67 rating and TVS protection make the camera a solid choice for exposed locations where durability is essential.
Comparisons with similar products in the market
When evaluating thermal cameras, three main factors usually drive the decision: sensor resolution, lens/IFOV (which affects detection distance), and system-level features (analytics, integration, ruggedisation). Against those axes the DS-2TD2167-35/PY positions itself as a high-resolution, long-focus thermal bullet with integrated analytics and robust environmental protection.
Many entry-level thermal cameras use 320 × 240 sensors. The DS-2TD2167-35/PY’s 640 × 512 array delivers significantly more pixel detail, improving recognition and detection ranges. For perimeters where distance matters, the higher resolution and a 35 mm lens can mean the difference between reliable detection and ambiguous thermals at the scene edge.
Hybrid systems that pair thermal with a high-resolution visible camera excel at identification and recording colour detail. However, they can be costlier and require more complex mounting or synchronization. The DS-2TD2167-35/PY focuses on dependable thermal detection at range, making it a simpler, lower-maintenance choice for sites where thermal signature and automated alarming are the priority. It can also be paired with visible cameras when visual confirmation is required.
Cooled thermal sensors offer exceptional sensitivity and are used for specialist lab or military applications, but they come at a steep cost and complexity. The VOx uncooled detector in the DS-2TD2167-35/PY provides a practical balance of sensitivity (NETD ≤ 35 mK), reliability and cost-effectiveness for most perimeter security and fire-prevention needs.
Customer feedback and testimonials
Publicly available customer reviews for specific model numbers are not always widely published. However, typical feedback themes from operators using similar Hikvision thermal bullet cameras include:
- "Reliable long-range detection — we catch trespassers well before they reach the inner fence line."
- "Good performance in darkness and fog compared with visible cameras."
- "Strong rugged build and easy integration with our VMS via ONVIF."
- "Temperature alarms give useful early warnings for plant equipment hotspots."
These representative comments reflect the expected experience when the camera is correctly specified for the site and installed by qualified technicians. For temperature-critical or regulated fire detection uses, customers emphasise the need to validate accuracy and perform site-specific calibration as recommended in the datasheet.
