Extra Info
Thermal and Optical Bi-spectrum
This camera leverages the power of both thermal and optical lenses working in tandem. The thermal module excels at detecting heat signatures, allowing it to "see" in complete darkness, through smoke, and in adverse weather conditions where traditional cameras fail. This is crucial for early fire detection and identifying individuals or vehicles based on their heat profiles. The optical module provides high-resolution color images, enabling visual identification and detailed surveillance during the day and with IR illumination at night. The combination ensures comprehensive coverage and verification.
Smart Analytics for Enhanced Security
The DS-2TD1228-2/QA incorporates advanced video content analysis (VCA) capabilities. This includes line crossing, intrusion, region entrance, and region exiting detection. Crucially, its deep learning algorithms classify objects as either human or vehicle, significantly reducing false alarms triggered by animals, swaying trees, or other non-threats. This intelligent filtering helps security personnel focus on genuine threats, improving response times and operational efficiency.
Precision Temperature Measurement and Fire Detection
Beyond general surveillance, this camera acts as a vital tool for fire prevention. It can monitor temperatures within a range of -20°C to 150°C with an accuracy of ±8°C. Users can set up multiple temperature measurement rules (points, areas, and lines) to identify abnormal heat build-ups. Coupled with its specific fire detection and smoking detection algorithms, the camera can trigger immediate alarms upon detecting potential fire hazards or active smoking, making it invaluable for warehouses, manufacturing facilities, and other areas prone to fire risks.
Resilient and Adaptable
Designed for demanding environments, the camera boasts an IP67 protection level, signifying its complete protection against dust and temporary immersion in water. It also includes TVS 6000V lightning protection, surge protection, and voltage transient protection, ensuring its durability and reliable operation in harsh outdoor conditions. The wide operating temperature range of -40°C to 65°C further extends its applicability across diverse climates.

Q&A
Q: What is the main benefit of a bi-spectrum camera like the DS-2TD1228-2/QA? A: The main benefit is comprehensive surveillance. The thermal module detects heat, allowing it to see in challenging conditions (darkness, smoke), while the optical module provides high-resolution visual detail for identification. This ensures continuous and reliable monitoring.
Q: Can this camera differentiate between humans and vehicles? A: Yes, the camera uses deep learning-based video content analysis (VCA) to classify objects as either humans or vehicles, significantly reducing false alarms and improving the accuracy of event detection.
Q: What is the temperature measurement range of this camera? A: The camera can measure temperatures from -20°C to 150°C (-4°F to 302°F).
Q: Is this camera suitable for outdoor use? A: Absolutely. The DS-2TD1228-2/QA has an IP67 protection level, making it highly resistant to dust and water, and is designed to operate in temperatures from -40°C to 65°C (-40°F to 149°F).
Q: Does this camera support local storage? A: Yes, it supports local storage via a MicroSD/SDHC/SDXC card up to 256GB.
Q: What is the maximum IR distance for night vision? A: The camera provides IR illumination up to 15 meters for clear night vision.
Q: Can the camera issue audible and visual alarms? A: Yes, it features both white light visual alarms with adjustable flashing frequencies and audio alarms with preset and user-defined voice alerts for VCA and temperature exceptions.
Q: What is NETD and why is it important for a thermal camera? A: NETD (Noise Equivalent Temperature Difference) measures the sensitivity of a thermal camera. A lower NETD value (like <40 mK for this camera) indicates a more sensitive detector, meaning it can detect smaller temperature differences and produce clearer thermal images.
Q: What power options are available for this camera? A: The camera can be powered by 12 VDC or Power over Ethernet (PoE 802.3af, class 3).
