Aerial and underwater surveillance give licensed investigators vantage points ground teams cannot reach: rooftops, large properties, shorelines, and submerged sites. Investigation Hotline offers drone and underwater imaging as part of Ontario private investigation work when the facts sit above or below normal street-level observation. This page explains when those tools fit a file. For service intake and equipment scope, see our drone and aerial surveillance page. Underwater methods are covered in depth in private investigation with underwater drones.
What is aerial and underwater surveillance in a PI case?
Aerial work usually means UAV (drone) photography or video flown by a trained pilot under Canadian aviation rules, paired with an investigation plan. Underwater work uses submersible cameras or underwater drones to document wreckage, lost property, or shoreline evidence. Both are tools inside a larger investigation, not stand-alone entertainment shoots. Ground tracking and surveillance still handles most person-following and public-place observation.
Who uses it: counsel, insurers, employers, municipalities, and individuals with a lawful need for elevated or submerged documentation.
What you receive: scoped flight or dive plans, dated media, and written findings tied to your objectives.
What this is not: recreational drone footage without licensing, privacy analysis, or chain of custody.
When does aerial surveillance help an investigation?
Aerial views help when the subject area is large, hard to approach on foot, or needs a time-stamped overview: industrial sites, open land, event perimeters, or search grids for missing people. Day and night capability depends on sensors and legal flight limits. Mitchell Dubros, founder of Investigation Hotline and a licensed drone pilot, has described the goal as meeting client needs with controlled, high-resolution capture rather than speculative flyovers.
Clients also request aerial documentation for work-process oversight and site inspections where a ground walk cannot show roof lines, stockpiles, or perimeter gaps. Those jobs still need a written objective so the pilot is not collecting hours of unused footage.
If you only need a general definition of surveillance methods, start with what surveillance is. If you need drone-specific tactics and video examples, use the drone and aerial posts on this site rather than treating this launch page as the full technical manual.
When is underwater surveillance the right tool?
Underwater imaging supports searches for sunk objects, vessel or dock inspections, and evidence that moved below the surface. Conditions (clarity, depth, current, ice) control what can be recovered on camera. Teams plan around safety and site access first. Do not DIY dive dangerous water for “proof”; licensed operators and proper equipment matter.
Rescue-adjacent searches and recovery documentation may involve coordination with authorities. Investigators clarify roles early so they do not interfere with official operations.
How do aerial and underwater tools differ from street-level PI work?
Street-level investigators document people, vehicles, and meetings in public spaces. Aerial and underwater tools document places and objects from unusual angles. Many files use both: a drone maps a property; ground teams verify who comes and goes. Mixing methods without a written scope wastes budget. Ask at intake which layer answers your question.
What legal and safety limits apply in Ontario?
Drone flights must follow Transport Canada rules, airspace restrictions, and privacy expectations. Filming people in places where they have a reasonable expectation of privacy can create legal risk even if a drone is “legal to fly.” Underwater work may require site permission, environmental care, and insurance. Investigation Hotline scopes jobs so evidence collection stays usable for counsel, not just visually impressive.
What should clients prepare before requesting aerial or underwater work?
- Define the decision you need (locate, inspect, document activity, support a claim).
- Provide maps, GPS pins, photos, and time windows.
- Disclose nearby airports, restricted zones, private property lines, and water hazards.
- Confirm who owns the site and whether written access exists.
- Ask how media will be stored, labelled, and delivered to your lawyer.
Where can you read the original service announcement?
Investigation Hotline announced expanded aerial and underwater capability in a December 2023 press release for Toronto clients. A downloadable PDF of that announcement remains available: press release on aerial and underwater surveillance services. Use the service pages for current intake, not the PDF alone.
Frequently asked questions
Can drones replace traditional surveillance?
No. Drones add a viewpoint. Most person-focused files still need ground observation and documentation.
Do you fly anywhere a client asks?
No. Airspace rules, safety, and privacy limits can block a flight. Alternatives are discussed at intake.
Is underwater drone work only for missing objects?
Lost objects are common, but inspections and scene documentation also appear in civil and insurance matters.
