It is equipped with an infrared sensor type Vanadium Oxide uncooled Focal plane detector with a resolution of 256x192 pixels, providing a clear thermal image.
By Camera offers two focal modes: 3.5 mm (Field of View 50.6° x 36.8°) and 7 mm (24° x 18°), allowing flexible applications.
The detection range is up to 449 m for vehicles and 146 m for people in 3.5 mm mode, and 897 m and 292 m in 7 mm mode respectively.
Additionally, By Camera has a CMOS sensor with 4 MP resolution for visible image, with the possibility of working in total darkness thanks to built-in IR diodes.
Functions such as digital detail enhancement (DDE), automatic thermal gain control (AGC) and noise reduction 2D/3D NR ensure high image quality.
By Camera supports H265/H264 compression, two-way sound and Smart Functions image analysis such as intruder detection, smoke detection, and temperature recognition.
Resistance to atmospheric conditions (IP67) and adapted for operation in a wide temperature range (-30°C to +60°C), ideal for outdoor applications.
By Camera it allows you to write on a microSD card (up to 256 GB) and offers a wide network configuration Capability including ONVIF and Interfaces RS-485.
Powered by PoE or 12 VDC, it is characterized by low power consumption (up to 4.9 W in basic mode).
