stable? Although the technology is continuously improving, some buildings behave like Faraday cages, interrupting the connection. What types of tech are needed? Smartphones and tablets combined with video conferencing software, such as Zoom, are readily available. All parties must be set up with the proper software. Fourth, verify that the RVI is being conducted at the proper location. The on-site technician should validate that he is at the correct specific location within the facility. For example, many riser rooms, valves and pumps in large facilities look similar. Be sure you're inspecting the right equipment. One suggestion is to turn on GPS location on the RVI device and use a "find my device" application. For recorded RVI, most devices automatically encode GPS metadata to photos and videos. Ensure privacy settings are appropriately enabled before starting the RVI. Finally, determine and document the specific inspection information to be gathered. On-site personnel may lack tech- nical expertise. It's important to communicate about what's being observed and what information must be obtained and documented. The remote observer must resolve all uncertain- ties by asking questions and directing the on-site technician. In this author's experience, conducting live video inspec- tions with two-way communication is more time-effective and yields more thorough results than asynchronous reviews. However, site conditions or local AHJ requirements may mandate recorded RVI. For example, poor Internet connec- tivity may inhibit synchronous communication, or perhaps an AHJ wants to maintain photos or video records. One way to address a lack of on-site expertise is to express your inner movie director and script the visit for on-site per- sonnel to follow. In the script, list every video shot required
