Frequently asked Questions (FAQ)

1. Why should I choose e-CAM81_CUNX_H01R1?

• e-CAM81_CUNX_H01R1 has support for NVIDIA® Jetson™ TX2 NX, Xavier™ NX and Nano™ developer kit.
• It is a 4K camera that comes with the HDR capability which helps to produce exceptionally clear and sharp images in challenging lighting conditions. This 4K HDR camera also has a high Signal to Noise Ratio (SNR), which helps to capture images with less noise in low lighting conditions
• Customer can choose the Jetson™ module according to their application requirements.

2. I have a custom Jetson™ TX2 NX carrier board. How do I interface e-CAM81_CUNX_H01R1 to my setup?

Currently e-con provides release package to support NVIDIA® Jetson Xavier™ NX / TX2 NX and Nano™ developer kit. For supporting your hardware setup, kindly write your requirements to sales@e-consystems.com.

3. What are the differences in camera interface between Jetson Xavier™ NX / TX2 NX and Nano developer kit?

• Although all the Jetson Xavier™ NX / TX2 NX and Nano™ developer kits have same camera interface support (2x2-lane MIPI CSI interface), the Jetson™ TX2 NX and Jetson Xavier™ NX module has far more capabilities in terms of camera performance.
• For example, Jetson Nano™ module has maximum support for 4 (2-lane) MIPI CSI cameras, whereas Jetson™ TX2 NX module supports up to 5 (2-lane) MIPI CSI cameras and can stream up to 12 MIPI CSI cameras via virtual channel support. Jetson Xavier™ NX module supports up to 6 (2-lane) MIPI CSI cameras and can stream up to 24 MIPI CSI cameras with virtual channel support.
