Drone and pole-camera inspection

Quick answerVerified September 25, 2026

What is drone and pole-camera inspection?

Cameras used to see places a technician cannot easily reach: small drones for roofs and high eaves, pole cameras for nests and soffits, and borescopes pushed through a drilled hole into wall voids. They find places worth checking. They do not confirm what is there, and a drone flown for business needs an FAA-certificated pilot.

Where it fits

Rooftop surveys across many buildings, where getting up there is most of the cost. In a two-year municipal study, drones surveyed 4,700 rooftops for water-holding containers at an average of 22.2 minutes per 100 rooftops, and cut field workload by 67.7% compared with traditional inspection.
Checking whether a nest is in use before anyone removes it. Federal guidance defines an in-use nest as one with viable eggs or nestlings, and puts the job of confirming that on the person destroying it. A pole camera that sees into the cup gives you that check without a ladder.
Wall voids with little insulation or clutter, checked by an experienced inspector, where the infestation is big enough to leave pellets or dead alates. That is the specific situation the drywood-termite borescope trial found it useful for.
Tall structures. Part 107 caps altitude at 400 feet above ground, but allows higher flight within a 400-foot radius of a structure, up to 400 feet above its highest point. That is the rule that makes high-rise facade and roof-edge work possible.

Where it does not

This is the part the brochure leaves out, so it is the part worth reading.

As confirmation. In the rooftop study the drone found containers; it could not show whether they held larvae, and ground crews had to check. Roof structures, vegetation and obstructions also meant small or hidden containers were likely missed. The image tells you where to go, not what you will find.
Borescope inspection as the only basis for a termite finding. Overall identification accuracy in the trial was 80.6%, but individual inspectors in the simulated field ranged from 35.7% to 78.6%. Several fell below 50% where voids held insulation, and the test samples included seeds, sugar and sand chosen because they look like pellets. The authors say it should not be relied on alone.
A technician with a drone and no Remote Pilot Certificate. The FAA requires one to fly under Part 107. Getting it means being at least 16, passing the FAA knowledge test and clearing a TSA security check. Keeping it means completing online recurrent training every 24 calendar months. Without it, the inspection flight is not a legal commercial operation.
Solo flights to the far side of a roof. Part 107 requires the pilot or a visual observer to keep the drone in sight, without aids other than corrective lenses, for the whole flight. If the ridge blocks your view, you need a second person or an FAA waiver, not a better camera.
Treating a camera view of a nest as clearance to remove it. The same federal guidance warns that nesting behaviour can make it hard to tell whether a nest is in use, especially for colonial, burrowing and secretive species. Eagle nests and nests of species also listed under the Endangered Species Act stay protected even when inactive.
