1 Overview
The Edge AI Box is a device intended for AI processing of large on-site data sets. The Edge AI Box - NX Indoor is a
highly functional device built into a small form factor. Our focus on space has led to a fanless design capable of intense
processing tasks.
1.1 Key Features of the Edge AI Box - NX Indoor
¢ NVIDIA JETSON Xavier NX
The JETSON Xavier NX GPU module is included for optimal performance, providing rapid data processing while
occupying minimal space. This allows for approx. 10X the AI processing speed compared to the Edge AI Box - Light.
¢ Deep Learning
The Edge AI Box - NX Indoor is a miniature computer ideal for environmental deep learning applications.
¢ Edge Computing
Cameras and sensors are located nearby, allowing for real-time data processing. This reduces transmission latency, loss
due to data compression, as well as data transmission costs. Moreover, analysis of uncompressed images provides
superior precision. Discover hazards in real time and alert alarm systems for immediate risk avoidance.
¢ Process data from ubiquitous IoT devices.
This small, fanless product can be installed near IoT devices, allowing for ethernet, USB, HDMI, LTE, and Wi-Fi
compatibility.
Users can also power external cameras and other devices using PoE (Power over Ethernet).
¢ Compatible with multiple connectivity standards, including LAN, Wi-Fi, and LTE.
The Edge AI Box uses connectivity features to send analysis results, logs, samples, metadata, and other information at
high speeds to the cloud.
*LTE transmission requires a SIM card.
¢ Compatible device environment
The Edge AI Box - NX Indoor is intended for indoor use. However, users may attach the optional cover for IP53 dust and
water protection. This prevents malfunction due to splashing water during cleaning or other hazards. Moreover, the Edge
AI Box - NX Indoor comes with wall mount support, and users can select optional pole and DIN rail mounts as well.

Notice
SIM card
• The Edge AI Box uses a standard SIM card. A converter card may be required if you use a microSIM or
nanoSIM card.
• Please refer to the instruction manual that came with your SIM card for a detailed explanation of SIM
card settings.
SIM card insertion
• Be sure to turn off the Edge AI Box and ensure that it is placed on a stable surface prior to inserting a
SIM card.
• Do not touch the IC portion of the SIM card.
• Be careful not to bend, crush, or otherwise damage the SIM card.
• LTE cannot be used unless the SIM card is securely inserted into the LTE module.
Body SAR
The Edge AI Box does not comply with Body SAR specifications. Please use with the antenna placed at
least 20cm from human bodies.
Body SAR regulations apply to devices with antennas placed within 20cm of human bodies.
National guidelines on technical standards for electromagnetic radiation absorbed by the human body, as
well as international guidelines on electromagnetic radiation exposure prevention, must be followed.
Such international guidelines include those held by the World Health Organization (WHO), of which
permitted values have been determined to be sufficiently safe regardless of the age or health status of the
user.
SAR (Specific Absorption Rate) reflects the permitted level of electromagnetic radiation exposure proposed
by national laws and international guidelines, and is expressed as the average electromagnetic energy
allowed to be absorbed by the human body. The local SAR value is 2.0W/kg (excluding the region distal of
the wrists and ankles, with is 4.0W/kg.)
Please refer to the following website for more details on Body SAR.
