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 a 210-degree articulating head and a 4.5-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 a 4.5″ (11.4 cm) IPS screen, and there is 32 GB of memory built into the handset. That leaves plenty of room for the 1 MP JPEGs and 1080p MPEG-4 videos.
The probe is 0.33″ (8.5 mm) across. Basically, if you can fit a standard ballpoint pen in the hole, the TD450S will fit.
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. Eight adjustable LEDs ring the forward lens and the side lens has one of its own. 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 lever on the monitor unit swings the tip through 210 degrees, two ways. 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.
The real limit is reach. The probe is 5.1 feet (1.55 m) long, which covers a wall cavity, an engine bay or a sink trap but will not follow a drain run across a garden. The Teslong NTS300 and the DEPSTECH DS300 below both give you 16.5 feet. Battery life is around four hours rather than a full working day, and you’ll find that the side camera won’t focus close enough if you’re in a really tight spot.
Other than that, at about $120 the Teslong TD450S Dual Lens Inspection Camera is a solid choice for more than occasional use. And it comes with a neat protective carrying case.

Professionals who already have Bosch 12V tools
|
The Bosch Professional GIC 12V-5-27 C is precisely that: an inspection camera for professionals. Especially if they already own a number of Bosch professional tools. Rather helpfully, a great many of them run off the same 12V battery system. That includes the BOSCH GTC400C Thermal Image Camera I reviewed in our roundup of thermal imaging cameras. Cutting down the number of battery types and chargers in the van is a real bonus for a busy contractor.
The headline number is the screen. It is a 5-inch panel running at 1280 x 720, sharper than anything else on this list, and the camera behind it sees 75 degrees and focuses from 30 to 80 mm. The cable is 59 inches (150 cm) long and 8.3 mm across. The head is IP67 and rated for half an hour submerged in diesel, engine oil, petrol or salt water, and the body itself is IP54. A 32 GB microSD card comes in the box, and stills and video come off it over USB-C.
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 feature they actually talk about is AutoUp. Whichever way you hold the rugged pistol-grip unit (overhead, on its side, upside down under a vehicle), the picture turns itself the right way up. It runs on a 12V Professional battery such as the Bosch GBA 12V 2.0Ah already sitting in a contractor’s other tools, or on four AA cells when that battery dies on site.
Then there is the price. In the US this camera comes from third-party sellers rather than from Amazon or a Bosch dealer, and it lands at around $500 against Bosch’s own UK list price of about £300. That is four times what the Teslong TD450S costs, and the Teslong has two lenses and an articulating tip that this Bosch does not. Buy the GIC 12V-5-27 C if you already own 12V Bosch batteries and you want a tool that will survive a decade in a van. If you don’t, almost every other camera on this list gives you more for the money.

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 $160 it is one of the pricier picks on this list, and it costs 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, and three times the reach of the TD450S, the NTS300 earns its price.

Anyone who needs a steerable tip on a slim probe
|
The Ralcam Two-Way Articulating Borescope is the one to reach for when the thing you need to see is around a corner rather than at the end of the hole. A control on the handle bends the last section of the probe two ways, so instead of poking blindly and hoping, you steer the lens onto the fitting, the weld or the dropped key.
It does that on a slim probe. At 5.5 mm across, the Ralcam goes into holes that the 8.5 mm cameras here simply will not enter, which matters for engine bores, door skins and conduit. An 8x digital zoom then pulls fine detail out of the middle of the frame (a cracked solder joint, a part number) without pushing the tip any closer.
Everything else is self-contained. There is a 5-inch HD screen in the pistol-grip handle, a 32 GB card in the box, and an IP67 rating on the probe, so standing water in a drain or a sump is not a problem. There is a microphone in the handle too, which is more useful than it sounds. You can narrate what you are looking at as you record instead of writing notes afterwards.
Reach is where it falls down. The cable is 5 feet (1.5 m), less than a third of what the DEPSTECH DS300 gives you for a lot less money, and there is a single lens rather than the dual-lens setup on our top pick. At about $130 the Ralcam sits mid-table on price, and what you are paying for is the steerable tip on a slim probe. If your jobs are straight runs down a drain, buy on cable length instead.

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 and 7.9 mm across, with seven LEDs on three brightness levels so a reflective pipe wall doesn’t blow out. It records 1080p video and 2 MP stills, the built-in battery runs for about 4 hours between charges, and there is 32 GB of memory already in the handset, so there is no card to buy. The kit ships with a hook, a magnet and a protective cap.
At around $50 it is the cheapest camera here that has a screen of its own, and the compromises are honest ones. The 4.3-inch display is the smallest of the screened picks, the 7.9 mm probe is one of the fatter ones, and there is no articulating tip, so you aim it by bending the cable. 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 7/32ths of an inch (5.5 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.
What you give up at $27 is everything the pricier cameras here do. There is no screen, so a phone has to come out and stay out for the whole job. There is no articulating tip, so you aim by bending the cable. And at 5 feet (1.5 m) the cable is the shortest on this list. If you want any of those things, start at the DEPSTECH DS300.

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.
How Much Reach Do You Need?
Cable length is where these cameras differ most, and it is the spec people overlook. The Teslong NTS300 and the DEPSTECH DS300 both run 16.5 feet (5 m), which is enough to follow a drain or a duct. Our top pick, the Teslong TD450S, stops at 5.1 feet (1.55 m), and the Ralcam and the NIDAGE are shorter still at 5 feet. For most jobs around a house or a car, five feet is plenty. For anything that runs the length of a building, buy on length first and features second.
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. Three of our picks have it: the Teslong TD450S swings 210 degrees two ways, the Ralcam does the same on a much slimmer probe, and the DXZtoz will hold an S shape to get past an obstacle. Fixed probes such as the DEPSTECH DS300 and the NIDAGE cost less, and you aim them by bending the semi-rigid cable instead. Pay for the moving head if you inspect engines and cavities, where what you need to look at is rarely straight ahead of the probe.
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
Specialist gear that used to be the exclusive property of specialists keeps getting cheaper. 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. Our top pick is the Teslong TD450S Dual Lens Inspection Camera. At about $120 it gives you two lenses, a 210-degree articulating tip and a screen of its own, and it will suit most users. If your jobs run deeper than five feet, buy the Teslong NTS300 or the DEPSTECH DS300 instead. And if you only need to look down one drain, the NIDAGE Wireless Endoscope costs less than a plumber’s call-out.
