Having an inspection camera can save you a fortune in contractor fees. It might be a blocked drain in an inaccessible place. Or you might have dropped your keys in an inaccessible place. Perhaps you’re chasing a cable in the attic but can neither find nor see it. In all these cases, an inspection camera can quickly come to your rescue.
As you’ll see from this review of inspection cameras, there’s a solution for almost every budget. And for every eventuality. Our top pick is the Teslong TD450S Dual Lens Inspection Camera. It’s a very capable camera that’s easy to use at a very reasonable price.
What Is the Best Inspection Camera?
The best inspection camera overall is the Teslong TD450S Dual Lens Inspection Camera. It pairs a twin-lens view with an articulating head and a 5-inch monitor, at a price most rivals don't match.
Only one of these inspection cameras is suitable for checking your rifle barrels — other than that, your budget and job requirements will determine your choice. Before we look at some of the details of our recommendations, here is a summary of the best inspection cameras.

The Teslong TD450S Dual Lens Inspection Camera grabs our top spot. It has an excellent balance of features and price, making it ideal for a whole range of users. The twin lenses send their pictures back to the 5″ (12.25 cm) IPS screen. And it records to MicroSD cards up to 32 GB in size. This means you have plenty of room for the 1 MP JPEGs and 1080p MPEG-4 videos.
The cable is about 5/16″ (8mm) in diameter. Basically, if you can fit a standard ballpoint pen in the hole, the TD450S will fit. But unlike your disposable pen, the Teslong will light your way and beam pictures back for you as well.
The two lenses on the inspection camera cable give you forward and side vision. They both have a 70-degree field of view. That’s about the same as a 28mm lens. And they are both illuminated by adjustable LED lights. It’s very handy to be able to see more than just what’s in front of you. There’s a trigger button under your index finger on the monitor. Press it to take a photo or start the video. Press and hold to switch between the front-facing and side-facing cameras.
Strikingly for a camera in this price bracket, the TD450S has an articulating head. A simple-to-use level on the monitor unit will change your view by 180 degrees in two directions. It’s smooth and simple to use.
Another advantage of the TD450S is the monitor unit. Inspection cameras that connect to your phone are all well and good. But the separate screen here, with its pistol grip, makes it easy to hold and use. Especially if it is cold and wet. And let’s face it, drains get blocked more when it’s wet! The grip is nice and chunky, with a textured rubber handle. All the controls fall nicely to hand. This is useful when your other hand is needed to manipulate the cable.
On the downside, there’s not much you can do to adjust the angle of view when using the camera. The cable is flexible, but there’s some wiggling needed to get it to look exactly where you want. And you can rotate the image on the screen by 180 degrees. You’ll find that the side camera won’t focus close enough if you’re in a really tight spot.
Other than that, the Teslong TD450S Dual Lens Inspection Camera offers a solid inspection camera for more than occasional use. And it comes with a neat protective carrying case and an attractive price tag.

Professionals who already have Bosch power tools

The Bosch Professional GIC 120 C inspection camera is precisely that—an inspection camera for professionals. Especially if they already own a number of Bosch professional tools. Rather helpfully, a number of tools run off the same battery system. This includes the BOSCH GTC400C Thermal Image Camera I reviewed in our roundup of thermal imaging cameras. Reducing the number of battery types and chargers is a real bonus for a busy contractor.
In other ways, you might find the specs of the GIC 120 C a little underwhelming. The cable is pretty short. There’s only one lens, and I wish you luck finding out the resolution of the pictures. The number quoted above is merely that of the (smallish) screen.
Like with professional cameras, it can sometimes puzzle people that they are so expensive but can appear underperforming compared with other cameras or even their phones. But ask a busy working professional, and you’ll see how the features are appreciated. A solid build, rock-steady reliability, and no frills are highly appreciated. It’s not just an inconvenience if a pro’s equipment fails. It could mean you lose out on a job opportunity.
The Bosch Professional GIC 120 C inspection camera gives the professionals what they need to get the job done. They can view the image live on a PC laptop. Whichever way they hold the rugged pistol-grip unit, the image will be the right way up thanks to the”up-is-up” screen display. And they have the convenience of the Bosch GBA 12V 2.0Ah battery, which they probably have in their other tools.

Anyone who wants a no-phone-required dual-lens inspection camera
|
The Teslong NTS300 Dual Lens Inspection Camera is a self-contained borescope for anyone who doesn't want a phone or an app in the loop. Instead of streaming to your handset, it has its own 5″ IPS screen built into the pistol-grip handle, so it works the same way whether you're in a basement with no signal or up a ladder with wet hands.
That self-contained design matters most for wall cavities, HVAC ducts, and engine bays — exactly the jobs this roundup is built for — because you're not fumbling with a phone mount or worrying about a dropped connection mid-inspection.
The cable runs 16.5 feet (5 m) and 8mm in diameter, with a semi-rigid build that holds its shape once bent into a duct or cavity. Both the forward and side lenses get independent LED lighting (6 front, 1 side), and the built-in 5,000mAh battery is rated for about 4.5 hours of continuous use. It's IP67 waterproof, and the kit includes a hard case with a hook, magnet, and mirror.
At around $150, it's one of the pricier picks on this list — more than our overall top pick, the Teslong TD450S. If you only need to check a drain once a year, the NIDAGE or DXZtoz below will save you money. But if you want a dedicated, no-phone-required screen you can hand to a less tech-savvy colleague, the NTS300 earns its price.

The Ralcam Two-Way 180-Degree Articulating Borescope has two useful features worthy of note. First of all, it works with your iOS or Android phone. This means that you have the superior screen quality that comes with today’s smartphones. And you don’t have to record to a separate memory card. The HD video or 2 MP stills are stored directly on your mobile device.
Secondly, it has an articulating head. The problem with some probes is that their rigidity limits their access to some tight corners. The Ralcam overcomes this. A braided titanium section at the end of the probe can be manipulated by the operator. This is a super-useful feature.
The probe is 1/3″ (8.5 mm) in diameter. So you can use the ballpoint pen test to know if it will fit. It is illuminated by 10 dimmable LED lights. The dimming function is important. Reflective objects will burn out in the image if they are too brightly lit. This will make it harder to see the details. But dimming the light solves this problem.
The Ralcam Two-Way 180-Degree Articulating Borescope is not the cheapest device in this review. But it brings together a useful collection of features that make it attractive to all sorts of users.

Anyone wanting dual-lens visibility without paying premium prices
|
The DEPSTECH DS300 Dual Lens Industrial Endoscope is the pick for occasional DIY jobs: two lenses instead of one, plus a proper 4.3-inch color screen built into the handle instead of relying on your phone or laptop.
That built-in screen and dual-lens switch make it easy to pick up for an occasional job and put away again. You can flip between the forward and side camera with one button, so you don't need to pull the probe out and reinsert it just to change your angle.
The 16.5-foot (5 m) semi-rigid cable is IP67-rated, with seven adjustable LEDs and a second-generation CMOS chip DEPSTECH says cuts picture lag when you switch lenses. It records 1080p video and 2 MP stills, and the built-in battery runs for about 4 hours between charges. The kit ships with a hook and magnet, though not a memory card, so budget for a MicroSD separately.
At around $45, it's still one of the cheaper cameras here, and the 2 MP still resolution is modest next to the 5 MP the old model claimed. If a screen-free, plug-into-your-phone setup is all you need, the NIDAGE Wireless Endoscope below is cheaper still.

The DXZtoz Industrial Endoscope offers all the convenience of an articulating lens head in a self-contained unit. The adjustable pistol-grip control unit offers full control of image features and the adjustable head.
That head can turn 180 degrees back on itself. And in an S shape, it can get past obstacles that might thwart a rigid probe. There are LED lights to illuminate the way, and they are adjustable to four different levels. It should cope with any situation.
The control unit is nicely designed and offers easy, logical access to the controls. It means everything can be controlled with one hand. The lens control, zoom, LED control, and shutter button fall under your thumb for convenience. This leaves the other hand free to insert the probe.
The whole kit comes in a decent carrying case with the cables, lens brush, and three useful attachments. These are a hook, a magnet, and a 90-degree mirror. So even if the bendy end doesn’t show what you need, the mirror might help. The DXZtoz Industrial Endoscope is not at the cheap end of the price spectrum. But it offers a solid set of features that make it worth considering.

The NIDAGE Wireless Endoscope offers a cheap, wireless inspection camera for most Android and iOS phones. You can prop your phone anywhere and concentrate on controlling the camera itself. That camera will give you 2 MP stills or 1080p video. And there are six adjustable LED lights to illuminate your path.
Apart from the wireless connection, another feature makes this an attractive option. The probe is only 3/16ths of an inch (5.2 mm) in diameter. That could make quite a difference in some situations. The probe is semi-rigid, giving you enough strength to push it into the cavity being inspected. And it’s flexible enough to access awkward areas.
For occasional use, it’s hard to question the value of the NIDAGE Wireless Endoscope. It’s very cheap, easy to use, and comes with a hook, magnet, and 90-degree mirror. Because it uses your phone’s screen, you’ll have excellent reproduction. And there’s no memory card to mess about with.

Anyone looking for a rigid borescope for their rifles
|
The Teslong Rigid Borescope is unique in this review in that it is completely rigid. And it makes a virtue of the fact. That’s because not everyone needs a borescope to poke about in drains or engines. Some people need to check the inside of a gun barrel. And they are just about as difficult to see into as a drain.
A rigid borescope is designed for this exact situation. And the Teslong is a decent, affordable answer to the problem. It will work with laptops and Android smartphones but not iOS. It should be a simple plug-and-play on most devices.
Several useful features make this a valuable tool. The diameter of the bore is 0.2″ (4.9 mm). So it will fit any caliber weapon down to 0.20 inches. The probe is stainless steel and engraved with length markings. So you can easily see how far down the barrel any problem is simply by looking at the gauge. And the probe is long enough for pretty much any rifle or shotgun.
It’s a niche market, for sure. But if you’re looking for an affordable way to inspect the barrel of your rifle, then the Teslong Rigid Borescope is a solid (or rigid) choice.
Buyer’s Guide—The Best Inspection Camera
What Is the Difference Between an Endoscope and an Inspection Camera?
Technically, an endoscope is a medical device. An inspection camera, or borescope, is for less intimate uses. And it’s important not to confuse the two. None of these inspection cameras is a medical device.
What Are the Main Features to Look Out For?
The bore (or diameter) of the inspection camera determines where it can reach. All of these cameras will fit in very small holes. Basically, almost anywhere you can think of that might get blocked or where you might have dropped something. And as you have seen, a couple of them would fit inside a standard ballpoint pen.
All these inspection cameras have adjustable lights, which is essential when exploring the unexplored nether regions of your car’s ventilation system or the washing machine drain.
The resolution of the images is not as vital as it would be for a normal camera. You won’t be producing gallery prints of your drainpipe. But, the higher the resolution, the clearer the image. All of these inspection cameras have at least passable pixel counts.
Moving Head or Fixed?
Having a camera end that can be articulated from the control end is a useful feature. And it’s one which carries a price increase in most cases. It really depends on what you need to look into.
Twin Lens or Single?
Again, there is usually a premium to be paid for a twin-lens inspection camera. The cameras without one often come with a 90-degree mirror attachment. Although this is not as convenient as being able to switch the view mid-inspection, it is a way around it on a budget
Conclusion: The Best Inspection Camera
These days, the seemingly unaffordable specialist gear that used to be the exclusive property of specialists is increasingly affordable. Some of the inspection cameras in this review are almost disposable, given their price.
So there’s plenty to choose from. Whether you’re looking for a one-time money-saving solution to a crisis or for more regular usage. There really is something here for everybody. Our top pick is the Teslong TD450S Dual Lens Inspection Camera. It’s affordable, offers solid features, and should suit most users.
