Buying guide

How to Choose an Inspection Camera for Your Trade

Each trade puts a different demand on the probe, the cable and the screen.

  1. Automotive: fit the spark plug hole

    Most engine checks go through the spark plug hole, so choose a probe of 8.5 mm or less. A dual-lens or articulating tip shows the cylinder wall, not just the piston top, and about 5 ft of probe is plenty under the hood.

  2. HVAC: see all the way around

    Inside a duct you want to scan the walls, not just look down the run. A rotating lens (NTS600 Rotating, T7 PRO) turns the side view 360°, and Wi-Fi remote viewing lets you show the picture on a phone or tablet.

  3. Plumbing: buy enough cable

    Measure the run first. Drain checks often need 16 ft or more: the NTS300 and NTS500 dual and rotating probes go to 16.4 ft and the MS450 Dual Lens to 50 ft. Probes are IP67-rated; keep the monitor dry.

  4. Record what you find

    Most models save photos and video to an included 32 GB microSD card (the TS43 needs your own card), so you can add evidence to a quote, report or warranty claim.

FAQ

Frequently Asked Questions

Inspection camera questions from DIYers and trade technicians.

What is the difference between a borescope and an endoscope?

Generally, “endoscope” is a medical term for a surgical device, but we frequently call our products “industrial endoscopes” to avoid confusing them with medical endoscopes. Teslong does not make any medical-grade surgical products. “Borescopes” is a term that is basically interchangeable with “industrial endoscopes” however we refer to all of our firearm inspection cameras as “borescopes” and the rest of our inspection cameras as “industrial endoscopes.”

What is a digital inspection camera used for?

Digital inspection cameras are good for looking anywhere that is difficult to see or access with the naked eye. This could be as simple as looking under the refrigerator for lost car keys or it could be a technical engineering application like performing a visual inspection on an aircraft engine. Digital inspection cameras have many uses, but most commonly they are used to look inside the wall of a house to aid running electrical or audio wiring and also for looking inside combustion chambers of automobiles to inspect for proper valve function.

Can you hire an inspection camera?

You can hire mechanics or home inspectors to perform inspections using inspection cameras, but generally you wouldn’t specify the tools they use to perform their work. Complicated and expensive inspection cameras can be rented, but this is usually only done by trained professionals. Most consumer digital inspection cameras are inexpensive enough that you can just buy them to perform the inspection yourself.

What camera do home inspectors use?

Home inspectors use whatever industrial endoscope camera they trust to get the job done. Ultimately, they need to get a good visual on their subject such that they can confidently make an accurate assessment of whatever they are looking at.

Do you need a borescope inspection camera?

Borescope inspection cameras are handy tools that save time and money - anyone who regularly performs do-it-yourself work around the house or automobiles should have one in their toolbox.

How do snake cameras work?

Snake cameras are a slang term for borescope inspection cameras, or industrial endoscopes. Snake cameras have a digital camera on the end of a rigid or flexible probe that is designed to access areas that you normally can’t see with the naked eye, thereby eliminating time-consuming disassembly or destructive inspection processes.

Which inspection camera is best for automotive work?

For engine work, look for a probe of 8.5 mm or less so it fits the spark plug hole, and a tip that can see the cylinder wall as well as the piston top. The TD500 and TD450s bend their tip 210° in two directions, the F6 PRO adds 4-way joystick steering, and the NTS600 Dual Lens switches between front and side cameras. Articulating models carry about 5 ft of probe, which is plenty under the hood.

What inspection camera should I use for HVAC ducts?

A rotating-lens probe is the easiest way to scan the inside of a duct: the NTS600 Rotating Lens and T7 PRO turn a side view all the way around without twisting the cable. Both have a 6-inch screen and Wi-Fi remote viewing, so you can also show the picture on a phone or tablet. For a fixed multi-angle view, the T6 PRO triple-lens camera offers split-screen viewing.

Can I buy just the monitor?

Yes. The NTS300, NTS500, NTS500B and NTS600 monitors are listed on their own on this page. The NTS500B monitor works with Teslong USB camera probes; for the other monitors, check the product page or ask our support team which probes fit before you order.

Inspection Cameras for Automotive, HVAC & Plumbing Work

An inspection camera puts an LED-lit camera on the end of a probe so you can see inside an engine, a duct or a drain line without taking it apart. This collection is organized around the trades that use one every week, so you can choose by job rather than by spec sheet.

Automotive, HVAC and Plumbing

For engine work, a probe of 8.5 mm or less fits the spark plug hole, and an articulating or dual-lens tip such as the TD500 or NTS600 Dual Lens shows the cylinder wall. For HVAC, the NTS600 Rotating Lens and T7 PRO turn the side view 360° inside ducts and stream it over Wi-Fi. For drains, cable length decides it: 16.4 ft on the NTS300 and NTS500 probes, and up to 50 ft on the MS450 Dual Lens.

Home Inspection and Spare Monitors

Home inspectors and DIYers can start with switch-on models like the TS43 and NTS500B, or Wi-Fi cameras that use a phone. NTS monitors are also sold on their own. Every camera comes with a 12-month warranty (3 years on the PRO models), free US shipping over $199 and a 30-day money-back guarantee.
