B256B1 Infrared Camera Module | CVBS Thermal Imaging Camera

B256B1 320×240 Infrared Camera Module

The B256B1 is a compact thermal imaging module built around a 320 × 240 sensor with a fast 50 Hz frame rate. It delivers simultaneous PAL analog and UVC digital video, making it easy to connect to both legacy displays and modern embedded processing platforms. The split‑body design — a miniature 19.5 mm × 19.5 mm × 20.8 mm camera head and a separate 33.5 mm × 33.5 mm × 16.5 mm Al Box — greatly simplifies integration into space‑constrained OEM devices. A broad 5 V–24 V power input, sub‑1.5 W power consumption, and standard UVC compliance make the module truly plug‑and‑play across Windows, Linux, macOS and Android. Full‑range image adjustments, including brightness/contrast control, five selectable palettes, stepless 1.0×–4.0× digital zoom, and horizontal/vertical/diagonal image flip, are accessible via UVC commands or ADKEY buttons. With an operating temperature range of −20 °C to 50 °C, this module is a reliable thermal core for portable inspection instruments, entry‑level security cameras, and industrial monitoring tasks.

Key Features

✓ 320 × 240 Thermal Resolution with Dual Video Output

The B256B1 outputs a 320 × 240 infrared image on two channels simultaneously: an analog PAL signal (CVBS) and a digital UVC stream. You can use either or both at the same time, bridging legacy and modern video systems.

✓ 50 Hz Real‑Time Frame Rate

A constant 50 frames per second delivers smooth, low‑latency thermal video, ideal for monitoring moving objects and dynamic scenes.

✓ F1.0 Large‑Aperture 3.6 mm Lens

The 3.6 mm lens with a fast F1.0 aperture gathers abundant infrared radiation and provides a wide 50° (H) × 37.2° (V) field of view for excellent situational awareness.

✓ Plug‑and‑Play UVC Digital Output

The digital video feed conforms to the USB Video Class standard. It works immediately with Windows, Linux, macOS, and Android hosts — no drivers, SDKs, or additional software required.

✓ Simultaneous PAL Analog Output

In parallel with the UVC stream, the module provides a standard PAL analog signal, allowing direct connection to analog monitors, DVRs, or video transmitters without format conversion.

✓ Full‑Range Power Supply and Ultra‑Low Consumption

The module accepts any DC voltage from 5 V to 24 V and typically consumes less than 1.5 W. It is equally suitable for USB‑powered setups, battery packs, and industrial 12 V/24 V systems.

✓ On‑Board Imaging Controls

Brightness and contrast are individually adjustable from 0 to 100. Five color palettes, stepless digital zoom (1.0×–4.0×), and horizontal/vertical/diagonal image flip are all available. Settings can be changed in real time via UVC commands or ADKEY events.

✓ Extremely Compact Split‑Body Design

The tiny camera head (19.5 × 19.5 × 20.8 mm) can be placed in extremely tight spots, while the Al Box (33.5 × 33.5 × 16.5 mm) remains in a more accessible location for cabling and control.

✓ Wide Temperature Range

Rated for continuous operation from −20 °C to 50 °C, the B256B1 performs reliably in both indoor and sheltered outdoor environments.

Q: What video outputs does the B256B1 provide?

A: It simultaneously outputs a PAL analog video signal (CVBS) and a UVC digital video stream. You can use both at the same time.

Q: What operating systems does the UVC interface support?

A: The UVC interface is driver‑free and works natively on Windows, Linux, macOS, and Android. Any host that supports USB Video Class will recognize the module as a standard camera.

Q: How can I adjust image settings such as brightness, contrast, and color palette?

A: Brightness (0–100), contrast (0–100), color palettes (0–4), digital zoom, and image flip can all be controlled via UVC camera controls or through ADKEY button events on the Al Box.

Q: Can I flip or mirror the image?

A: Yes. The module supports horizontal, vertical, and diagonal image flipping. This is useful when the camera is mounted upside down or a mirrored view is needed.

Q: Is the frame rate adjustable?

A: No. The frame rate is fixed at 50 Hz (50 frames per second).

Q: How does the digital zoom function?

A: You can apply a stepless digital zoom from 1.0× to 4.0× through the UVC interface. The zoomed image is available on both the UVC and PAL outputs.

Q: What power supply do I need?

A: The module accepts any DC input from 5 V to 24 V. Typical power consumption is below 1.5 W, making it compatible with standard USB ports (5 V), batteries, and industrial power sources.

Q: What are the dimensions of the B256B1?

A: The camera head measures 19.5 mm × 19.5 mm × 20.8 mm. The Al Box (interface unit) measures 33.5 mm × 33.5 mm × 16.5 mm.

Q: Can the B256B1 be used outdoors?

A: The operating temperature range is −20 °C to 50 °C. For outdoor use, install the module in a suitable waterproof enclosure; it does not have an IP rating on its own.
