Best Inspection Cameras Under 100: See Inside the Engine Without Taking It Apart

A rattle inside a wall, a leak behind an engine, or a lost bolt down a drain all share one problem: you cannot fix what you cannot see, and taking everything apart to look is the most expensive way to find out.

Inspection cameras, also called borescopes and endoscopes, solve that by sending a tiny camera on a semi-rigid cable into the gap, with its own light, and showing the picture on your phone or on a built-in screen. The idea is simple, but the buying choice is not, since probe size, cable length, screen type, and app support change what you can actually inspect.

This guide compares five verified inspection cameras with clear probe sizes, resolutions, cable lengths, and screen options, so you can pick the camera that fits your holes, your phone, and your patience for apps.

30-second answer: For most buyers, the Anykit 9.8 foot endoscope is the best all-round pick: 1920P resolution, 8 adjustable LED lights, a semi-rigid snake cable, and IP67 waterproofing, with phone viewing on iPhone and Android. If you want no app and no phone at all, the MugEasy camera with a 4.3 inch IPS screen is the pick. For the longest cable in this guide, the MugEasy 32.8 foot dual-lens screen camera covers drains and long pipe runs.

How the picks compare

The five picks split into phone cameras and screen cameras. The BAZO, Anykit, Ditomil, and Teslong cameras connect to a phone and show the picture in an app, which keeps the camera small and cheap but depends on your phone and its connector. The MugEasy camera carries its own 4.3 inch IPS screen, so it works with no app, no phone, and no pairing, at the cost of a larger handle. Cable length is the second split: from 9.8 feet for close work to 32.8 feet for drains and long runs.

The shortlist, at a glance

Anykit Endoscope Camera, 1920P, 9.8 Foot, our best overall pick, stands out because a sharp 1920P phone camera with 8 LEDs and IP67 waterproofing for cars, walls, and household gaps. Its standout spec is 1920P, 9.8 ft, IP67.

MugEasy Endoscope Camera with 4.3 Inch Screen, 32.8 Foot, Dual Lens, our best screen camera pick, stands out because a no-app screen camera with a long 32.8 foot cable and dual lenses for drains and pipes. Its standout spec is 4.3 in screen, 32.8 ft, dual lens.

BAZO Endoscope Camera, 1920P, 18 Foot, our best mid-length pick, stands out because a 1920P phone camera with a 6.9 millimetre probe and 8 LEDs for engines, walls, and pipes. Its standout spec is 1920P, 6.9 mm probe, 18 ft.

Ditomil Endoscope Camera, 1920P, 16.4 Foot, our best value phone camera pick, stands out because a 1920P phone camera with 8 LEDs and a 16.4 foot cable for cars, walls, and plumbing. Its standout spec is 1920P, 16.4 ft, IP67.

Teslong USB-C Endoscope Camera, 10 Foot, our best usb-c pick pick, stands out because a USB-C phone camera with 8 LEDs and attachments for modern iPhones and Android phones. Its standout spec is USB-C, 10 ft, attachments.

Budget tiers

At the compact end, the Teslong USB-C camera and the Anykit 9.8 foot camera suit car, wall, and household inspections where a short cable and a phone screen are enough. In the middle, the BAZO 18 foot camera and the Ditomil 16.4 foot camera cover engine bays, pipes, and HVAC runs with longer reach. At the long-reach end, the MugEasy 32.8 foot screen camera is for drains, sewers, and long pipe inspections where a phone camera cable simply runs out.

In-depth reviews

Anykit Endoscope Camera, 1920P, 9.8 Foot

Best Overall

The Anykit camera is the best all-round phone endoscope: 1920P resolution, 8 adjustable LED lights, a semi-rigid snake cable, and IP67 waterproofing, for iPhone and Android phones. Its 9.8 foot length suits the close and medium inspections most buyers actually do, from engine bays to wall cavities.

The included hook, magnet, and USB charging cable, as listed under its built-in media, make it a complete kit rather than a bare camera, which matters when the inspection turns into a retrieval. The limit is cable length: drain and long pipe runs need a longer camera, which is why the MugEasy long-cable pick exists.

• 1920P resolution
• 8 adjustable LED lights
• 9.8 foot semi-rigid cable
• IP67 waterproof, iPhone and Android

Good for: cars, walls, and household inspections. Watch out: cable too short for long drains.

MugEasy Endoscope Camera with 4.3 Inch Screen, 32.8 Foot, Dual Lens

Best Screen Camera

The MugEasy screen camera is the no-phone answer: a 4.3 inch IPS screen, 1920P resolution, 8 LED lights, a 32.8 foot semi-rigid cord, and dual lenses, with IP67 waterproofing. It suits sewer, drain, and long pipe inspection where a phone camera cable runs out and where a wet phone is a bad idea.

Dual lenses give a forward and a side view option, which helps in pipes where a single forward view misses the wall defect you passed. The trade-off is size and handling: a screen handle with 32.8 feet of cable is a bigger tool than a phone camera, and it suits planned jobs better than pocket checks.

• 4.3 inch IPS screen, no app needed
• 1920P resolution, 8 LED lights
• 32.8 foot semi-rigid cord
• Dual lens, IP67 waterproof

Good for: drains, sewers, and long pipes. Watch out: larger and heavier than a phone camera.

BAZO Endoscope Camera, 1920P, 18 Foot

Best Mid-Length

The BAZO camera is the mid-length phone pick: 1920P resolution, a 6.9 millimetre probe, 8 adjustable LED lights, and an 18.04 foot semi-rigid cable, with IP67 waterproofing for Android and iPhone. That probe size fits most engine and wall gaps while staying small enough for pipe work.

Its length covers engine checks, wall inspections, pipe runs, and HVAC gaps that a 9.8 foot camera cannot reach, without the bulk of a 32.8 foot drain camera. The trade-off is phone dependence: it needs your phone, its app, and its connector, so check those before ordering.

• 1920P resolution
• 6.9 millimetre probe, 8 adjustable LEDs
• 18.04 foot semi-rigid cable
• IP67 waterproof, Android and iPhone

Good for: engines, walls, pipes, and HVAC. Watch out: needs a phone and app to view.

Ditomil Endoscope Camera, 1920P, 16.4 Foot

Best Value Phone Camera

The Ditomil camera is the value phone pick: 1920P resolution, 8 adjustable LED lights, a semi-rigid snake cable, and IP67 waterproofing, at 16.4 feet for iOS and Android. It covers car repair, wall inspection, pipe inspection, engine checks, plumbing, and home repair in one small camera.

Its length sits between the Anykit short camera and the BAZO mid-length camera, which makes it a sound single purchase for buyers who do not know their longest run yet. The listing gives no probe diameter, which is why tight-hole buyers should prefer the BAZO pick with its stated 6.9 millimetre probe.

• 1920P resolution
• 8 adjustable LED lights
• 16.4 foot semi-rigid cable
• IP67 waterproof, iOS and Android

Good for: general car, wall, and pipe checks. Watch out: no probe diameter stated in the listing.

Teslong USB-C Endoscope Camera, 10 Foot

Best USB-C Pick

The Teslong camera is the connector-correct pick for modern phones: a USB-C endoscope with 8 LED lights, a 10 foot flexible waterproof cable, and fibre optic scope design, compatible with iPhone 15, 16, and 17 plus Android phones. Its included hook, magnet, and side-view mirror attachments add retrieval and corner viewing.

At 10 feet it suits close car, wall, and household work rather than long drains, and its USB-C connector is the point: buyers with a modern phone avoid adapters entirely. Owners of older Lightning iPhones should not buy this variant, and should choose a Lightning camera or a screen camera instead.

• USB-C connection
• 8 LED lights
• 10 foot flexible waterproof cable
• Hook, magnet, and side-view mirror included

Good for: modern USB-C phones and close work. Watch out: does not fit older Lightning iPhones.

Buying criteria: what actually matters

Probe diameter decides which holes you can enter. A 6.9 millimetre probe, as the BAZO listing describes, fits most engine and wall gaps, while an ultra-thin 5.5 millimetre probe, as the Pancellent-style listings describe, fits spark plug holes and narrow fittings. A probe that is too fat for your hole is useless no matter how good its picture is, so measure your smallest access point before buying.

Resolution decides whether you can tell a crack from a shadow. The 1920P resolution claimed by the BAZO, Anykit, and Ditomil cameras gives a sharper picture than 1080P for reading part numbers and judging crack edges, but resolution claims vary by brand and by app, so treat them as guidance and prioritise adjustable LED lighting alongside them.

Screen versus phone decides the whole experience. A built-in screen, like the MugEasy 4.3 inch IPS screen, works immediately with no app, no pairing, and no phone battery worry, while a phone camera gives a bigger, brighter display and easy photo sharing at the cost of app setup and connector compatibility. Check your phone connector, USB-C or Lightning, before buying a phone camera.

Cable length and stiffness decide reach and control. A semi-rigid cable holds its shape to push around a bend, while a fully flexible cable flops, and a cable that is too short ends the inspection at the interesting part. The picks here range from 9.8 feet to 32.8 feet, so match length to your longest realistic run, not your shortest.

Sizing and fit guide

Measure your access hole before choosing probe size. A spark plug hole, a drain cleanout, and a wall cavity all have different minimum diameters, and a camera that fits the wall may not fit the plug hole. When a listing gives no probe diameter, as some phone camera listings do not, treat that as a gap and prefer a camera that states its probe size for tight work.

Match cable length to the run plus handling slack. A 16.4 foot cable suits most engine and household runs, while a drain or sewer inspection needs 32.8 feet or more, since the camera must travel the pipe and still leave cable in your hands. Buying short and regretting it is worse than carrying a longer cable coiled.

For phone cameras, check connector and app support for your exact phone model and operating system version. The Teslong camera is a USB-C model for iPhone 15 and later plus Android phones, while older iPhones need a Lightning variant, and an app that has not been updated for your phone version can turn a good camera into a paperweight.

How to use it well

Feed the cable slowly and watch the screen, not the cable, since pushing fast kinks the cable and scrapes the lens. Rotate the probe gently to orient the picture, and use the adjustable LEDs to avoid washing out close surfaces: dimmer light often shows more detail at close range than full brightness.

Use the included hook, magnet, and mirror attachments where the camera provides them, as the Teslong listing describes, to retrieve small parts and see around corners. A camera that only looks is half a tool; a camera that can also grab the bolt you dropped is a complete one.

Clean and dry the probe after wet or dirty work, especially after drain and sewer use, and coil the cable loosely for storage. A tightly kinked cable develops a permanent bend that fights you on the next job, and a dirty lens fogs the next picture before you start.

Safety notes

Never push a camera into a live electrical panel, a running engine, or a moving part. Inspection cameras are for still, safe spaces, and a probe near a fan belt, a live bus bar, or a hot exhaust is a damaged camera at best and an injury at worst. Stop the machine, isolate the power, and then inspect.

Wear eye protection and gloves for drain, sewer, and engine inspections, and wash hands and equipment after dirty work. Drain cameras carry contamination back out with them, and a camera that is not cleaned spreads it to the next surface it touches.

Do not force a probe that will not pass. A stuck probe in a wall or a pipe is a second problem on top of the first, and forcing it can break the lens off inside the cavity. If the probe stops, withdraw, rotate, and try a different angle, or accept that the gap needs a thinner probe.

Real-world notes

In practice, phone cameras get used most for quick checks: a look inside a wall before cutting, a check behind an engine before removing a cover, a peek down a drain before calling a plumber. Their small size and phone screen make them the camera that is actually in the toolbox when the question arises.

Screen cameras get used most for long, dirty, or shared jobs: drains, sewers, and pipe runs where a phone would get wet or where several people need to watch the screen at once. A built-in screen also suits workers who do not want app setup on a shared or older phone.

The most common real-world surprise is how often the picture needs light adjustment rather than more resolution. Owners who learn the LED dimmer and the side-view mirror attachment get better pictures from a modest camera than owners who chase the highest resolution number and leave the light on full.

Mistakes to avoid

Buying a phone camera without checking the connector is the most common inspection camera mistake. A USB-C camera does not fit an older Lightning iPhone, and an app that needs an update you cannot install leaves a new camera useless. Check connector and app support for your exact phone before ordering.

Buying a cable that is too short is the second mistake. A camera that stops three feet short of the leak tells you nothing, and no accessory extends a semi-rigid cable, so buy the length your longest run needs, plus slack.

Forcing a probe into a tight hole is the third mistake. A stuck or broken probe inside a wall or pipe turns an inspection into a retrieval job, so withdraw and rethink when the probe resists, rather than pushing harder.

Care, storage, and lifespan

A inspection camera lasts longest when it is cleaned after dirty work, stored dry, and inspected before use, and the picks in this guide reward that routine more than any single feature does. Wipe off mud, grit, and road salt before storage, since grit left on moving parts and fasteners grinds away at them on the next use, and salt left on metal invites corrosion even on coated surfaces.

Store the inspection camera where it will not be crushed, bent, or buried under heavier tools, and keep small parts, fasteners, and attachments with it rather than in a separate drawer. A inspection camera that lives in one place, complete and clean, is a inspection camera that gets used correctly, while a inspection camera with missing parts gets improvised around, and improvisation is where damage starts.

Inspect before every use and retire anything cracked, bent, frayed, or loose. A inspection camera that has been overloaded, dropped hard, or soaked repeatedly may look fine and still fail, so when a part feels wrong, sounds wrong, or moves in a way it did not before, replace it rather than trusting it for one more job. The cost of a replacement is always smaller than the cost of a failure.

What to check on arrival

When the box arrives, check the contents against the listing before you throw the packaging away: model number, piece count, and included accessories should match what you ordered. A missing tool, a wrong size, or a damaged case is far easier to resolve with the packaging and the order details still in hand.

Test the fit on your actual vehicle, space, or job before the return window closes, not on the day you finally need it. A inspection camera that does not fit your receiver, your arch, your gap, or your storage space is a return, and discovering that on the morning of the job turns a simple fix into a delay.

Keep the manual, the model number, and the seller details with the inspection camera, since restocks, spare parts, and warranty questions all need them later. A photo of the model label stored on your phone costs ten seconds now and saves a long search when you need a replacement part in a year.

Questions to ask before you buy

First, what is the exact job this inspection camera must do, and what is the measurement that proves it fits? For this guide, that means the height, size, capacity, or fitment figure from the listing, checked against your own measurement, not against a guess or a similar model.

Second, what happens when this inspection camera wears out, breaks, or runs out? A reusable product needs a recharge or repair path, a consumable product needs a restock plan, and a fitted product needs a removal plan, and a purchase with no answer to that question becomes clutter or a repeat emergency purchase.

Third, does this inspection camera match the other gear you already own? A camera needs the right phone connector, a mount needs the right receiver and coupler, a guard needs the right model year, and a kit needs the right consumables, and a mismatch in any one of those turns a good product into a return.

Fourth, what will you do if the first use disappoints? Test it early, inside the return window, and keep the packaging until that test passes, since a product tested on day one can be exchanged, while a product tested on day ninety often cannot.

Do I need a screen or is a phone camera enough?

A phone camera is enough for most quick checks, since your phone gives a large, bright display and easy photo sharing, and the BAZO, Anykit, Ditomil, and Teslong picks all work this way. A built-in screen camera, like the MugEasy 4.3 inch IPS model, is better for long, dirty, or shared jobs where you do not want app setup, phone battery worry, or a wet phone near a drain.

What probe size do I need?

A 6.9 millimetre probe, as the BAZO listing describes, fits most engine, wall, and pipe gaps, while an ultra-thin 5.5 millimetre probe fits spark plug holes and narrow fittings. Measure your smallest access point before buying, and prefer a camera that states its probe size when your work involves tight holes, since some listings give no probe diameter at all.

How long a cable do I need?

A 9.8 foot cable, like the Anykit pick, suits close car and household work, a 16.4 to 18 foot cable, like the Ditomil and BAZO picks, suits engine bays, pipes, and HVAC runs, and a 32.8 foot cable, like the MugEasy screen camera, suits drains and long pipe runs. Buy for your longest realistic run plus handling slack, since a short cable cannot be extended.

Will a phone inspection camera work with my iPhone?

It depends on the connector and the app. The Teslong camera in this guide is a USB-C model for iPhone 15, 16, and 17 plus Android phones, while older iPhones with a Lightning port need a Lightning variant. Check the connector, the app name, and your phone operating system version against the listing before ordering, since app support decides whether the camera works at all.

Are inspection cameras waterproof?

The phone cameras in this guide are listed as IP67 waterproof, including the BAZO, Anykit, Ditomil, and MugEasy models, which suits wet pipes, drains, and engine bays. IP67 covers the probe and cable in water, not necessarily the phone or the screen handle, so keep the display end dry and check the listing for exactly which parts carry the rating.

Can an inspection camera find an engine leak?

It can show you the leak path, the wet fitting, and the cracked hose, which is often the hardest part of the diagnosis, but it does not test pressure or confirm a repair on its own. Use the camera to locate the problem, then confirm with the proper mechanical test for that system before replacing parts, since a wet patch on camera can come from a nearby source.

Verdict

Buy the Anykit 9.8 foot camera if you want a simple, sharp phone camera for cars, walls, and household gaps. Buy the MugEasy 4.3 inch screen camera if you want no app and no phone involved, and buy the MugEasy 32.8 foot dual-lens camera if drains and long pipes are your real work.

Whichever camera you choose, check your phone connector or choose a screen model, buy the cable length your longest run needs, and feed the probe slowly. The camera that fits your holes and your phone is the one that gets used instead of gathering dust.

Before you order

Run this final check before you buy any inspection camera in this guide. Confirm the exact fitment, size, or capacity figure against your own measurement, not against a similar model or a memory of one. Confirm the connector, receiver, arch, gap, or storage space it must match, since a single mismatch turns a good product into a return. Confirm what is included in the box, including tools, hardware, attachments, and charging cables, so the first use does not stall on a missing part. Then order the pick whose strengths match your most common job, keep the packaging until you have tested it, and test it within the return window, since a product tested early can be exchanged and a product tested late often cannot.
