Inspection Cameras for Property Work

Home inspection is mostly a question of access. The problem is nearly always somewhere you cannot get your head, and the cost of looking — cutting an access hole, pulling a fixture, entering a crawlspace — is high enough that people guess instead. A probe on a cable removes that trade-off.

What people look for

Water staining and mold behind wet walls, insulation gaps and rodent damage in cavities, blocked or disconnected HVAC ducts, debris in dryer vents, wiring runs before drilling, and pest activity in soffits and crawlspaces.

Choosing your setup

Built-in screen models from 3.5" to 5" are the practical choice for professional inspectors — you are often on your back in a crawlspace, and a standalone unit with TF card recording puts photos straight into the report. Phone-connected probes plug into an iPhone or Android over USB-C or Lightning and cost less, which suits homeowners and occasional use.

Specs

Probes from 3.9 mm to 8.5 mm on 1 m to 3 m cables, IP67 waterproof, adjustable LED illumination, and articulating tips that steer around framing and duct bends. For drain and pipe work specifically, see plumbing borescopes.

Choosing the Right Borescope

Can I inspect walls, HVAC ducts, chimneys and crawlspaces?

Yes — a borescope lets you see inside wall cavities, ductwork, chimneys and crawlspaces through a small access hole, so you can check for wiring, leaks, mold or pests without opening up the structure. Choose a flexible cable to follow existing runs.

What cable length do I need to reach inside walls or ducts?

1m handles most wall-cavity and behind-appliance checks; choose 2m–3m for longer duct runs and chimneys. A flexible cable follows bends and gravity, which suits ducts and voids better than a rigid tube.

Which model is best for home inspection?

A model with a built-in screen and a flexible or semi-rigid cable is easiest for home use — you don't need your phone free while working overhead. Add articulation if you need to look sideways inside a cavity rather than straight ahead.

FAQ

What is a borescope and what is it used for?

A borescope is an inspection camera designed to access hard-to-reach areas. It is widely used for automotive diagnostics, pipe inspection, HVAC maintenance, and industrial applications.

How do I choose the right borescope?

Choosing the right borescope depends on your needs. Key factors include probe diameter, cable length, articulation (2-way or 4-way), and whether you need a standalone screen or smartphone connection.

What industries are your inspection cameras suitable for?

Our borescopes are used across multiple industries, including:

  • Automotive repair
  • Plumbing and drainage
  • HVAC inspection
  • Construction and maintenance
  • Industrial equipment inspection
How long does the battery last?

Battery life depends on the model, but most standalone borescopes provide 3–5 hours of continuous use on a full charge.

Which borescope is best for beginners?

For beginners, we recommend starting with a model that has a built-in screen and simple controls. These models do not require additional setup and are easier to operate.
