The Lntech SNQ-2978C is a derivative of the high-performance 2978 series, engineered specifically for applications demanding a minimal physical footprint. It retains the core functionality of the SNQ-2978 – the Sony IMX290 sensor, 1080p60 video, and simultaneous EX-SDI/CVBS output – but is built on a compact 30mm diameter circular PCB. This form factor is critical for integration into space-constrained, miniature, or discreet commercial products, drones, and specialized security devices where a standard 38x38mm board is not feasible.
| Attribute | Description |
|---|---|
| Imaging Core | Sony IMX290 (1/2.8") |
| Physical Form Factor | Circular, 30mm Diameter |
| Output Protocol | Simultaneous: EX-SDI + CVBS |
| Resolution & Speed | 1080p60, Progressive Scan |
| Sensitivity | Min. Illumination: 0.00008Lux (F1.2, AGC ON, DSS ON) |
| Key Differentiator | Miniature Size + Full HD 60fps Performance |
| Critical Functions | WDR, DEFOG, 3D-DNR |
| Lens Control | Fixed Iris or DC-Iris (No Auto Focus) |
| Target Application | Miniature/Embedded Systems, Discreet Security |
1. Miniaturized Design
The most significant feature of the SNQ-2978C is its 30mm circular printed circuit board (PCB). This reduction in size and change in shape from the standard 38mm square requires careful component layout and design optimization to maintain signal integrity and thermal performance while achieving a much smaller area.
2. Performance Parity
Despite its smaller size, the SNQ-2978C does not compromise on core performance metrics:
High Frame Rate: Maintains 60fps output for capturing fast-moving objects.
Low-Light Sensitivity: Utilizes the same Sony IMX290 sensor to achieve starlight-level (0.00008 Lux) performance.
Output Flexibility: Continues to provide simultaneous EX-SDI and CVBS outputs, a key feature for hybrid system designs.
3. Application-Specific Advantages
This module is not a direct replacement for a 38mm board but a solution for a different set of problems:
Discreet Security: Allows for the creation of much smaller and more easily concealed camera housings.
Consumer & Commercial Electronics: Can be embedded into products where a 38mm board is too large.
Drones/UAVs: The reduced size and weight are critical for aerial platforms.
Specialized Equipment: Fits into machinery and equipment for vision inspection where space is limited.
4. Design Considerations
Integrators should note:
Lens Compatibility: The smaller board may require specific lens holders or interfaces designed for the 30mm diameter.
Housing Design: Requires a custom housing designed for a circular, 30mm core, different from the common 38mm square standard.
Thermal Management: The compact size may influence heat dissipation; ensuring adequate airflow in the final housing is recommended.
