Inspection Cameras | HVAC Borescopes & Endoscopes

Need to see what’s going on inside ducts, drains, coils or wall cavities without cutting extra access panels? Our HVAC inspection cameras — also called borescopes or endoscopes — give you a clear view of hard-to-reach areas so you can diagnose problems faster, quote with confidence and avoid unnecessary call-backs.

Regular inspection and cleaning of coils, drains and internal components is widely recommended in Australian energy and consumer advice to keep systems efficient and avoid damage from blocked drains and dirt build-up. Using an inspection camera lets you confirm what’s happening inside before you start pulling anything apart.

Why HVAC technicians use inspection cameras

• Non-destructive fault finding – look inside drains, ducts, cavitites and risers without cutting new access holes.
• Faster diagnostics – quickly see whether a condensate drain is blocked, a coil is visibly fouled or cables have been damaged.
• Better documentation – capture stills and video for quotes, reports and before/after proof for strata and facility managers.
• Supports safer work – remote visual inspection can reduce time spent in some roof or ceiling spaces when used alongside WHS procedures.

Featured HVAC Inspection Camera

Robinair OTC 3880X Video Inspection Scope (5.5 mm Camera)

The Robinair OTC Automotive Video Inspection Scope with 5.5 mm Camera – 3880X is a robust, professional-grade video scope that works brilliantly on HVAC as well as automotive and industrial jobs.

• Ultra-slim 5.5 mm camera head – ideal for tight penetrations, condensate drains and wall cavities.
• 36" detachable camera snake – long enough for most ceiling or riser inspections.
• Wireless 3.5" colour display – remove the screen and keep it where you can see it while the probe goes up into the ceiling.
• Image and video recording – capture files for quotes, handover and maintenance reports.
• Four adjustable LEDs on the camera head for clear pictures in dark cavities.
• IP67-rated camera head for added dust and moisture protection.

In practice, most tradies use the 3880X for:

• Inspecting condensate drain lines and pans for blockages or biofilm build-up.
• Checking coils and heat exchangers for corrosion or debris before cleaning.
• Tracing cable runs and inspecting junction boxes in ceiling and roof spaces.
• Checking behind wall linings around suspected water ingress or construction defects.

How to choose the right inspection camera

1. Probe diameter & length

• Diameter: 5–8 mm is ideal for drains, penetrations and tight cavities.
• Length: around 1–1.5 m suits local checks, while longer probes are better for long duct runs or roof spaces.

2. Flexibility vs rigidity

• Flexible probes weave easily through bends and drains.
• Semi-rigid probes hold their shape and are easier to aim at coils or junction boxes.

3. Image quality & lighting

• Look for at least HD resolution so you can spot fine cracks, corrosion and debris.
• Adjustable LED brightness helps you avoid glare on shiny metal surfaces inside ducts and coils.

4. Screen, recording & connectivity

• Built-in or wireless screens keep set-up quick on site.
• Recording to card or memory is extremely useful for reports, QA documentation and client education.

5. Durability & rating

• Choose at least an IP67-rated camera head for typical HVAC and light plumbing conditions.
• A sturdy carry case helps protect the probe and keeps all accessories together.

Typical HVAC jobs made easier with a borescope

• Blocked condensate drains – see where sludge or foreign objects are sitting before you start clearing.
• Duct inspections – check for loose internal insulation, debris, accidental damage or poor joints.
• Coils and heat exchangers – visually assess the level of dirt or corrosion before applying coil cleaner.
• Wall and ceiling cavities – trace pipe and cable runs, look for obvious water ingress paths or poorly fixed services.
• Post-work verification – grab photos after repairs or new installs to add to your job file.
