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.
