Dahua DH-TPC-BF3221-T 256x192Thermal EPoE Hybrid Bullet IP Security Camera

Dahua DH-TPC-BF3221-T 256x192Thermal ePoE Hybrid Bullet IP Security Camera

The Hybrid Thermal Network camera combines an uncooled VOx
256 x 192 thermal imager with a 2 MP visible-light sensor for
cost-effective, long-range surveillance in a rugged all-in-one package.
The thermal imager coupled with an athermalized, focus-free lens
produces crisp images in total darkness and sees through rain, fog, and
snow. The visible imager with an IR illuminator delivers superior video in
any lighting condition.

Uncooled Vanadium Oxide (VOx) Technology

Dahua thermal cameras use an uncooled Vanadium Oxide (VOx)
sensor that delivers higher thermal sensitivity in a more compact and
cost-effective package. Vanadium Oxide cameras are also more reliable,
as compared to other thermal imaging technologies, due to less moving
parts.

Athermalized Lens

The athermalized lens used in Dahua thermal cameras maintains the
focus position passively and without power over a wide temperature
range.

High Thermal Sensitivity

The VOx detector offers high thermal sensitivity (≤ 50 mK) that allows
Dahua thermal cameras to distinguish objects in a scene with minimal
temperature differences. The camera captures detailed images where
thermal contrast between object and background is minimal.

Active Alarm

The camera is equipped with a white-light illuminator and an external
speaker that can be triggered when the camera detects an abnormal
event either via the thermal or the visible-light sensor. The camera also
takes a snapshot of the scene and can record the snapshot.

Enhanced Power over Ethernet (ePoE) Technology

Dahua’s innovative ePoE technology offers a plug-and-play solution to
transmit power and data over long distances via Ethernet or coaxial
cables, reducing installation time and saving money. ePoE technology
is a viable, cost-effective solution for extending transmission distances
and for converting existing, coax-based analog systems into IP systems.
For video security and surveillance installers, ePoE technology saves
time and money by reducing overall cabling requirements, allowing for
existing coax cable to be used, and minimizing the number of peripheral
devices needed. For new installations, ePoE offers the ability to design
long-distance applications without the need for additional repeaters.

Thermal Color Palettes

Dahua thermal cameras provide a choice of color palettes onboard the
camera that help to distinguish thermal variations and patterns in an
image. The color tones correspond to the apparent surface temperatures
of the target.

Interoperability

The camera conforms to the ONVIF (Open Network Video Interface
Forum) specification, ensuring interoperability between network video
products regardless of manufacturer.

Environmental

With a temperature range of 10° C to +35° C (50° F to +95° F), the
camera is suitable for many internal applications. Subjected to rigorous
dust and water immersion tests and certified to the IP67 Ingress
Protection rating makes it suitable for applications were water and dust
are present.

Protection

The camera allows for ±20% input voltage tolerance, suitable for the
most unstable conditions for outdoor applications. Its 6 KV lightning
rating provides effective protection for both the camera and its structure
against lightning
