1. e-CAM50_CUNX - FAQ |
|
1.1 Why should I choose e-CAM50_CUNX? |
|
e-CAM50_CUNX has support for NVIDIA® Jetson Xavier™ NX Developer Kit, which has a power-efficient, high-performance and compact Jetson Xavier™ NX module. |
|
It benefits new cloud-native support and accelerates the NVIDIA software stack in as little as 10 W with more than 10x the performance of its widely adopted predecessor Jetson™ TX2 know more. |
|
1.2 I have an e-CAM50_CUNANO camera. Can I interface and use it with NVIDIA® Jetson Xavier™ NX Developer Kit? |
|
Yes, e-CAM50_CUNANO product is compatible with NVIDIA® Jetson Xavier™ NX Developer Kit. Please refer to the Getting Started Manual on how to connect with the Developer Kit and install the binaries. |
|
1.3 I have a custom Jetson Xavier™ NX carrier board. How do I interface e-CAM50_CUNX to my setup? |
|
Currently e-con provides release package to support NVIDIA® Jetson Xavier™ NX Developer Kit. For supporting your hardware setup, kindly write your requirements to sales@e-consystems.com |
|
1.4 What are the differences in camera interface between Jetson Nano™ and Jetson Xavier™ NX ? |
|
Although both the Jetson Nano™ and Jetson Xavier™ NX developer Kits have same camera interface support (2x 2-lane MIPI CSI interface), the 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 Xavier™ NX module supports upto 6 (2-lane) MIPI CSI cameras and is capable of streaming upto 24 MIPI CSI cameras with Virtual channel support. |

e-con Systems provide V4L2 based camera driver. And hence it can be accessed by OpenCV. |
|
Refer to this blog article on how to achieve maximum performance using OpenCV. |
|
In this blog, the installation steps will be referred to Jetson™ TX2. But you can use this as reference and port the same to Jetson Xavier™ NX. |
|
1.11 How to install OpenCV and CUDA after flashing Jetson Xavier™ NX with e-con provided quick start package? |
|
CUDA and OpenCV can be installed using SDK Manager application provided by NVIDIA. SDK Manager application has an option to install the CUDA and other Software toolkit to Jetson board without erasing the rootfs. For more information, refer the SDK. |
|
1.12 How to install e-con camera without flashing the Jetson Xavier™ NX board? |
|
Jetson Xavier™ NX development kit will boot from external SD card. It carries all the boot binaries, kernel image, device tree, module drivers and rootfs. e-con Systems have provided option to upgrade the binaries in the SD card without affecting the existing root file system content. For more information, refer to "Upgrade procedure" section in e-CAM50_CUNX "Developer Guide". |
|
1.13 Which document I need to refer to use the camera once I received the module? |
|
For quick reference, you can start with "Getting Started Manual" under hardware documents section. This document contains the detail about the product deliverables, how to connect the camera to Jetson Xavier™ NX and how to flash the quick start package and test the camera. |
|
1.14 Can I use this camera in NIR light condition? |
|
The default lens supplied with the camera has IR Cut filter- filters the IR light. You can test it using other IR pass lens. For choosing different lens kindly write your requirement to sales@e-consystems.com. |
