Planning a remote inspection requires careful consideration of various factors to ensure its success. Firstly, a technological analysis should be carried out to determine whether the current systems can be interconnected or replaced by new solutions. If the analysis yields positive results, companies and institutions must choose equipment and technology to ensure optimal results throughout the project.

Developing Standard Operating Procedures (SOPs)

Preparing for remote company inspections also involves developing Standard Operating Procedures (SOPs). This step entails establishing transparent and standardized procedures for conducting remote inspections, covering aspects such as equipment setup, data collection, communication protocols, and reporting requirements. SOPs help ensure consistency, efficiency, and compliance with quality standards.

Training and Education

Another crucial stage in preparation is providing training and education. Companies should offer comprehensive training and education programs to employees involved in remote inspections, including inspectors, maintenance personnel, and relevant stakeholders. It’s essential to ensure that staff are proficient in operating remote inspection tools, interpreting data, and adhering to safety protocols.

Choosing Technologies for a Remote Inspection

Among the technologies available, augmented reality (AR) platforms are valuable tools for remote inspections. Then, one employee is on-site, and the other can conduct the inspection remotely. What is essential is that an employee may be on-site and guided by the remote inspector, being his “hands and eyes.”

Utilizing AR technology, inspectors can perform their duties safely and efficiently within a controlled environment, significantly reducing the need for employees to travel to inspection sites. Industrial-grade AR glasses provide inspectors with immersive visualizations and real-time data overlays, enhancing their inspection capabilities and resulting in significant cost savings, including travel expenses.

Artificial intelligence also expands the possibilities and improves the quality of remote inspection. AI primarily automates some processes and allows automatic assessment of the condition of elements based on vision or sensor data, reducing the need for “manual” work and reducing costs. AI capabilities enable proactive maintenance strategies, ultimately increasing equipment reliability and minimizing downtime.

Security Measures

Safety is paramount in remote inspections, so preparation should involve implementing robust security measures to protect sensitive data and ensure compliance with data privacy regulations. This may entail deploying encryption protocols, access controls, and secure communication channels to safeguard information transmitted during remote inspections. Many companies prefer not to store their data in the cloud, and platforms like Nsflow offer on-premises or hybrid solutions, such as the Nsflow box, to address these concerns.
