Dahua Thermal Network Hybrid Speed Dome – TPC-SD2221

System Overview

Featuring a dual-lens, fixed speed dome, this series provides an all-in-one solution for capturing video surveillance for indoor and outdoor applications. Together with Thermal and Visible Technology, the camera is the perfect solution for dark, small area monitoring applications. The series combines one thermal camera for monitoring in total darkness and one visible camera with Smart IR for confirming details.


Uncooled Vox Technology

Dahua thermal cameras use uncooled Vox sensor technology. Because of small size and better performance, it’s a cost-effective solution for thermal security.

High Sensitivity
High thermal sensitivity(<50mK) makes cameras capture more image details and temperature difference information.

Fire Detection & Alarm
With a built-in Fire detect function, the camera has the ability to detect fire in a long distance. because the thermal camera is sensitive to temperature, so the accuracy of fire detection will be higher than a visible camera.

Temperature Measurement
Dahua thermal cameras (-T models) provide remote temperature monitoring functionality with the ability to set temperature threshold alarms. Object temperatures can be monitored in the daytime or at night, making them ideal for usage in a power plant or oil extraction applications where overheating can be dangerous. When the temperature exceeds the set threshold, an alarm is triggered. The temperature range is between -20 °C to 550 °C (-4°F to 1022 °F).

Intelligent Video analysis (IVS)

Dahua camera is equipped with a built-in intelligent analytic algorithm based on the video, which can realize intelligent functions like Tripwire and Intrusion, to quickly and accurately respond to monitoring events in a specific area, It can enhance monitoring efficiency. In addition, the camera supports intelligent tamper detection, which is to generate warning messages via detecting dramatic scene change and to guarantee effective video surveillance.

Smoking Detection

Smoking detection is a built-in video analytics algorithm that combines with thermal imaging and visible light technology, based on the Dahua Deep-learning AI algorithm to automatically detect if there is someone smoking in a detection area and to trigger an alarm. Value: Dahua thermal camera can provide real-time monitoring, in the use of AI technology, to automatically detect people’s smoking behavior and provide intelligent voice and light warning (Loudspeaker and white light, etc.) in an effort to dissuade or correct, and avoid potential risk and loss


With a temperature range of -30 °C to +60 °C (-22 °F to +140 °F), the camera is designed for extreme temperature environments. Subjected and certified to rigorous dust and water immersion tests, the IP67 rating makes it suitable for demanding outdoor applications.


Supporting ±15% input voltage tolerance, this camera suits even the most unstable conditions for outdoor applications. Its 6KV lightning rating provides protection against the camera and its structure from the
effects of lightning.
