System Overview
Featuring a dual lens Pan and Tilt camera, this series provides an all-in-
one soluon that is especially benecial for temperature measurement.
Together with Dahua Thermal and Starlight technology, the camera’s
long range capabilies are able to be ulized even at night. The series
combines one thermal camera for monitoring in total darkness and one
camera with Starlight funconality and a motorized lens for conrming
details up close.
Funcons
Uncooled VOx Technology
Dahua thermal cameras use uncooled VOx sensor technology. Their
small size and beer performance make them a cost-eecve soluon
for thermal security.
High Sensivity
High thermal sensivity (<40 mK) allows cameras to capture more image details and temperature dierence informaon.
Fire Detecon & Alarm
With built-in re detecon funconality, the camera has the ability to
detect res from long range. Because thermal cameras are sensive to
temperature, they provide higher re detecon accuracy than standard
cameras, making them parcularly t for applicaons such as forest re
prevenon.
Intelligent Video System (IVS)
IVS is a built-in video analycs algorithm that delivers intelligent funcons to monitor a scene for tripwire violaons, intrusion detecon, and
abandoned or missing objects. A camera with IVS quickly and accurately
responds to monitoring events in a specic area.
Environmental
With a temperature range of –40°C to +60°C (–40°F to +140°F), the
camera is designed for extreme temperature environments. Subjected
and cered to rigorous dust and water immersion tests, the IP66 rang
makes it suitable for demanding outdoor applicaons. For enviorments
with rain, sleet, snow and fog, an integrated wiper (oponal) provides
users with clear visibility at all mes.
Protecon
The camera supports wide range voltage input (100–300V AC), suitable for the most unstable condions for outdoor applicaons. Its 6kV
lightning rang provides eecve protecon for both the camera and its
structure against lightning.
Temperature Measurement
Dahua thermal cameras (-T models) provide remote temperature monitoring funconality with the ability to set temperature threshold alarms.
Object temperatures can be monitored in dayme or at night, making
them ideal for usage in power plant or oil extracon applicaons where
overheang can be dangerous. When the temperature exceeds the set
threshold, an alarm is triggered. The temperature range is between –20
°C to +550 °C.
