1MP OV9281
Introduction
Global shutter cameras eliminate rolling shutter artifacts to better capture moving objects, and OV9281 is just one of them.
Image Sensor
| Sensor Model | OV9281 |
|---|---|
| Shutter Type | Global Shutter |
| Active Pixels | 1280 x 800 |
| Resolution | 1 MP |
| Image Sensor Format | Type 1/4″ |

At Arducam
The Arducam OV9281 camera breakout incorporates Omnivision 1/4-inch 1 Mp (1280×800) CMOS digital image sensor which is capable of operating at up to 60fps in 1MP ( 1280×800 ) resolution at 1-lane MIPI mode. The OV9281’s high frame rates make it an ideal solution for low-latency machine vision applications.
The global shutter technology allows you to reduce or eliminate unwanted image artifacts, which occur with traditional rolling shutter image sensors as a result of motion during image capture. The sensor’s global shutter and excellent low-light sensitivity allow it to be used for any application that needs gesture detection, head/eye tracking, and depth and motion detection.

Hardware Connection
For Raspberry Pi 5:
The Raspberry Pi 5 has two 22-pin camera csi connectors, both located between the Ethernet and HDMI ports. When you plug in the cable, the silver contacts face the Ethernet port.
- 22pin-22pin Connection
For Raspberry Pi 3-4:
The camera connector is between the Ethernet and HDMI ports. When plugging in the cable, the silver contacts must face the HDMI port.
- 15pin-22pin Connection
