Ultra Low Light: Ultra low light Sony STARVIS IMX327 sensor
The camera uses the Sony Low Light STARVIS IMX327 sensor which is a diagonal 6.46 mm (Type 1/2.8) CMOS active pixel type solid state image sensor with square pixel array and 2.13 million effective pixels. The chip uses analog 2.9 V, digital 1.2 V, and interface 1.8 V. This highly sensitive low-light camera can capture extremely sharp images with minimal noise at extremely low light conditions. It features low power consumption, high functionality, high sensitivity, low dark current and no smear. The sensor applies R, G, and B primary color mosaic filters, as well as a variable electronic shutter.

Among the Sony STARVIS series sensors, IMX290, IMX462, and IMX327 are some of the more popular ones. Though they are all belong to the STARVIS series, there are some differences between them. Please see the following table about the similarities and differences:
| Specifications | Sensor | ||
| IMX462 | IMX290 | IMX327 | |
| Mega Pixels | 2.10MP | 2.07MP | 2.07MP |
| Max Resolution | 1920x1080 | 1920x1080 | 1920x1080 |
| Optical Size | 1/2.8'' | 1/2.8'' | 1/2.8'' |
| Pixel Size | 2.9μm×2.9μm | 2.9μm×2.9μm | 2.9μm×2.9μm |
| G Sensitivity* | 10471 | 5486 | 10471 |
| Max Frame Rate | 120fps(sensor) | 120fps(sensor) | 90fps(sensor) |
| NIR Sensitivity(850nm)* | ~1 | ~0.5 | ~1 |
G Sensitivity*: Gravity sensitivity is an important indicator of camera performance in low light conditions. Higher the G sensitivity, better is the low light performance.
NIR sensitivity*:NIR imaging performance is one of the most crucial features for smart surveillance, smart traffic monitoring, and agricultural applications.
