The **FTG-A4-R** is an industrial-grade, high-performance thermal imaging camera core developed by **Guide Sensmart**. It is specifically designed for integration into security systems, UAVs (drones), and industrial monitoring equipment. Below is a breakdown of its key electronic components and specifications. --- ### 1. Core Technical Specifications The electronics of the FTG-A4-R are centered around a Long-Wave Infrared (LWIR) Uncooled VOx detector. | Feature | Specification | | :--- | :--- | | **Detector Type** | VOx Uncooled FPA | | **Resolution** | 384 × 288 pixels | | **Pixel Pitch** | 12μm (High sensitivity) | | **Spectral Range** | 8μm to 14μm | | **NETD** | ≤40mk @ F1.0, 25°C | | **Frame Rate** | 50Hz (PAL) / 60Hz (NTSC) | --- ### 2. Electronic Interface & Connectivity The "R" in the model name often denotes **Radiometric** capabilities (temperature measurement). Its electronic interface allows for seamless integration into host systems. * **Video Outputs:** * **Digital:** Supports LVDS or DVP (Digital Video Port) for raw data processing. * **Analog:** Supports standard CVBS (PAL/NTSC) for direct monitor connection. * **Control Interface:** * Uses **UART (TTL)** or **RS232** for serial command communication. * Supports the **SDK** for custom software integration. * **Power Supply:** * Typical operating voltage: **4V to 6V DC**. * Power Consumption: Low power design, typically **<1.5W** during steady state. --- ### 3. Image Processing Electronics The onboard FPGA/DSP handles sophisticated image enhancement algorithms before the signal reaches the output: 1. **NUC (Non-Uniformity Correction):** Built-in shutter-based or shutterless correction to ensure image uniformity. 2. **DDE (Digital Detail Enhancement):** Electronics-based sharpening to highlight small objects in low-contrast scenes. 3. **Pseudo-color Processing:** Supports multiple palettes (White Hot, Black Hot, Iron Red, etc.) via internal lookup tables. 4. **Temperature Measurement:** The "R" version features onboard calibration for spot, line, and area temperature analysis. --- ### 4. Physical & Environmental Design The electronics are hardened to withstand industrial environments. * **Connector:** Usually a 30-pin or 50-pin Hirose-style board-to-board connector for all signals and power. * **Operating Temp:** -40°C to +70°C, ensuring the electronic components do not drift significantly under heat. * **Weight:** Extremely lightweight (approx. 20g - 45g depending on the lens), making it ideal for gimbal-mounted electronics. ---
