DH-TPC-DF1241N Hybrid Thermal Network Eyeball Camera256 x 192 Thermal Sensor and a 4MP CMOS Sensor 2 mm, 3.5 mm, or 7 mm Fixed Thermal Lens Option

The DH-TPC-DF1241N Hybrid Thermal Network camera combines an uncooled VOx 256 × 192 thermal imager with a 4 MP visible-light sensor for cost-effective, long-range security in a rugged all-in-one package.

The DH-TPC-DF1241N 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.

The DH-TPC-DF1241N with a built-in Excessive Temperature Detection and Smoking Detection issues an audible and visual alert. Hybrid thermal cameras let you see the visible and the invisible.

Uncooled Vanadium Oxide (VOx) Technology

Dahua DH-TPC-DF1241N 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 DH-TPC-DF1241N 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 DH-TPC-DF1241N 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.

Excessive Temperature Detection and Alarm

With built-in temperature functionality, the DH-TPC-DF1241N camera can detect a rapid rise in temperature over a short time and issue an alarm even at long distances.

Because thermal cameras are sensitive to temperature, they provide higher detection accuracy than standard cameras, making them particularly fit for applications such as forests, warehouse complexes, and industrial areas.

Intelligent Video System (IVS)

IVS is a built-in video analytic algorithm that delivers intelligent functions to monitor a scene for Tripwire violations, intrusion detection, and abandoned or missing objects. A camera with IVS quickly and accurately responds to monitoring events in a specific area.

Smart Alarm

The DH-TPC-DF1241N 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.


Dahua DH-TPC-DF1241N network cameras are equipped with a series of key cybersecurity technologies including: security authentication and authorization, access control, trusted protection, encrypted transmission, and encrypted storage. These technologies improve the camera’s ability to prevent malicious access and to protect data.


With a temperature range of –22 °F (-30 °C) to +140 °F (60 °C), the camera is designed for extreme temperature environments. The camera complies with the IP67 rating, makes it suitable for demanding outdoor applications.


The DH-TPC-DF1241N 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.
