2.0 Detailed Product Information
2.1 Description
The SNQ-3581F-M is a modular camera core designed for integration
scenarios where a single printed circuit board is too large or
inflexible. It consists of two independent units: a miniature 25mm diameter circular sensor board that contains only the Sony IMX385 image sensor, and a separate 25mm x 52mm main board that houses the EN781F processor, power management, and output interfaces (HD-SDI/EX-SDI and CVBS). The two boards are connected by a supplied ribbon cable,
allowing them to be physically separated and mounted in different
locations within a device. This provides ultimate flexibility for
product designers working on drones, automotive systems, custom
security solutions, and specialized industrial equipment.
2.2 Split Architecture Benefits
This design solves common integration problems:
Space Constraints: The tiny sensor head fits where a full board cannot.
Thermal Management: Keeps heat from the processor away from the sensor.
Maintenance: Allows for easy replacement of individual components.
Optical Design: Enables more creative and optimal lens and sensor placement.
2.3 Image Performance
High Resolution: Captures and outputs 1080p video at 60 frames per second.
Extreme Low-Light Performance: Delivers clear images in near-total darkness (0.000008 Lux).
Professional Features: Includes Wide Dynamic Range (WDR), Digital Fog Removal (Defog), and Digital Zoom.
2.4 Output Options
The main board provides two video output options, selectable via
OSD:
HD-SDI / EX-SDI: Digital output via an SMA connector for professional long-distance transmission.
CVBS: Analog composite video output for compatibility with legacy
systems.
2.5 Physical Installation
Components: 1x Sensor Board (Ø25mm), 1x Main Board (25x52mm), 1x Interconnect
Cable.
Mounting: Requires a custom housing designed to hold both components and manage the cable.
Power: 12V DC is connected to the main board. Typical consumption is < 1.80W.
