As a home inspector, my toolbox includes a variety of testing and measuring tools: screw drivers, nut drivers, framing square, concrete and wood moisture meters, temperaturehumidity meters, multi-meters, GFCI & AFCI testers, infrared and probe thermometers, binoculars and a couple of really nice digital cameras to document the appearance of the residence or structure.

Two hands required for a thermal temperature picture, one holding a digital IR thermometer directed at the object while aligning the camera with my other hand to “capture” the reading works well enough; however, a lightweight IR camera attachment to my cell phone is quicker and gives my client a true visual representation of temperature variance.

During a recent home inspection with the house temperature set at 75 and the exterior temperature 61 (picture 1), I felt a breeze several inches away from the chipped plaster above the receptacle and wanted to know more. Placing my anemometer meter at the opening, a 3 mph wind speed was recorded, the draft I felt several inches away. A wide view of the wall was provided by the K&F Concept IR camera that displayed a 9 degree wall temperature difference within 24” inch span (lack of or missing insulation). Removing the cover and receptacle (outlet), I was able to easily insert the lens for a look behind the wall. As the pictures captured, there was no insulation directly behind the receptacle box, above (bent the lens cable upward) and below using the side view camera. The red, yellow, blue, green IR picture is the outside (fiber cement siding). The exterior outlet aligns with the cold spot to the right of the interior outlet and the blue in the upper right corner is the interior outlet. I did not attempt to locate the source of the air leakage, annotating in my report further evaluation by a licensed contractor for options and cost. The nine pictures provided by the K&F Concept and IR camera provide a more comprehensive visual understanding than a mere draft from the outlet.

What is the water bottle for?
I drilled a hole on each end, passed the cable through secured with tape making a lens “stand off” for better observation looking in HVAC duct. With the rounded bottle, I’ve gone 14 feet without getting stuck.

The IR camera comes in a protective small semi-hard case, easy to use with the ability to annotate comments directly onto each picture.

The scope is lightweight and easy to use. All functions (picture, video, light, etc.) controlled by your thumb, except for the side view camera switch which is at the base of the cable. Packaged in a protective hard plastic case, with two metal latches and top and bottom foam padding cut to fit the cable, camera, USB cable and three included lens attachment options is more than adequate. A small magnet, 90 degree mirror and hook to fish wire, or “I dropped my ring in the drain” recovery tool are nice additions.

Providing two options for image transfer (one via the provided USB cable or by removing the mini SD card) gives the user flexibility.

As a home inspector, having a “third eye” is nice to answer any lingering questions regarding temperature and other issues: wall cavities, HVAC units, duct, vents, smoke chamber, chimney…

Adding the K&F Concept infrared thermal camera attachment to my tool inventory will allow more accurate reporting. Well worth the investment.

The picture shows a plumbing issue not visible without the scope. We also have video of active leak.

I purchased this after reading the reviews and also because I needed a long camera flex scope. I had to travel to CT from NC to survey a trimaran that was interested in purchasing and did indeed purchase. I specifically needed to inspect the stainless chainplates that secure the mast shrouds. This was a racing rig and this securement is super critical and needs to be well inspected. Of course they were inaccessible expect in one had a camera endoscope type device, which I did. I hadn't even tested the Tesslong out before the flight but I did charge it up. I was super simple to use. The cable is indexed for proper orientation. Attach and turn it on and put it to work ! Super clear images well lit also ! I high recommend for any type of mechanical inspection. You will need a micro sd adapter card for a few dollars to view your saved photos on a computer. Plastic instrument doesn't seem to be made of high impact plastic or rubber coated plastic so I would handle it with care. The case is high impact plastic and the instrument is well protected in the case. Battery life seemed well within what I need for the days work.

As an HVAC technician I can honestly say that this tool has been one of my best investments i have ever purchased at such a low cost. I own a $1300 combustion analyzer yet this $150 tool helps me make more money in the field. I primarily use this camera to inspect heat exchangers. I have purchased 6 cameras within the last 10 years including other K&F Concept models and this camera beats them all by a land slide! The camera cable itself has durable Material and will not get cut by metal. The cable is also very flexible yet sturdy enough to bend in the position you want it to take a proper picture. The picture quality is literally unbelievable compared to what iv used in the past. You can clearly identify things that are less than 1/4” long and a millimeter thin. Make sure you adjust the date before sending pictures over to customers though! You’ll get screwed! Lol. But yes if you do hvac and want to do a thorough check in heat exchangers this is your tool!

If you're looking for a good all round inspection camera this is it....
I purchased this with specific task in mind:
1. Plumbing inspection and leak detection especially when the drain is clogged...
2. Automotive and light duty Truck repair - used it to do visual inspection inside cylinders on diesel engine valve, cylinder walls and piston.. I used it to locate hidden bolts while changing out cam driven distributor on 1994 Toyota Camry..
3. Home HVAC inspection on evaporator, condenser, and supply side air registers.

I am retired and no I am not a professional.. just like fixing things and the K&F Concept Inspection Camera is soooo much better than using an inspection mirror and a flash light....plus you don't have to climb over or under things to do inspections....My wife uses it to find things that she has dropped behind the washing machine, dryer or the stove...

Great item must buy works great for getting good views, high quality imaging make sure you put protective cover over camera lines. I did it and accidentally broke mines hoping company might be able to send a replacement.

I have a 2003 Camry 2.4L engine with a P0420 OBD-II Trouble Code. I was told to buy new catalytic converters. With a price tag of $2,500 for new converters, it made sense to do my own inspection and work-around. There are many catalytic cleaners on the market, but how do I know if the treatment I used worked? I needed to get some pictures inside the Catalytic converters, and they had to be bright and clear. After studying every review of the K&F Concept , it looked like the best bang for the buck. As I treated my catalytic converters, the pictures revealed my success along the way. I saved a ton of money with the . It took about 15 minutes to figure out the buttons and what they do. It's all in the settings and MODE switch. The OK button takes you through where you need to go in each MODE search. It's as simple as that. I love the fact that the screen tilts on the handle. The tilt comes in very handy. As for the quality of the machine itself, there is nothing negative to say. The screen is large and the images are crisp and sharp. I love the camera cable. It is heavy duty and strong. It feels very professional while using it. The camera itself is tiny enough, about the size of a pencil. In fact, I just ordered the 3.3 foot
Borescope-Inspection Camera Accessory that goes with the . It's Waterproof. It comes with a Hook & Magnet Mirror. The 3.3 foot camera cable completes the for me. I found caps to cover the two ends on the 16 foot cable and will hang it in my garage. I plan to use the 16 foot cable for my home inspections. Then I will put the 3.3 foot cable in the beautiful case the comes in. I will use the 3.3 foot cable more often for auto repairs, etc. I would recommend the K&F Concept without any reservations. I was not paid for this review. Nor was I asked to make one. It all comes from the love I have for this device. This camera is a great tool to have when you need it. It can save me a lot of money when inspecting things around the house. Being able to look inside of things without taking them apart is a dream come true for me.

I am an HVAC tech I use this camera during my furnace safety inspections , literally pays for itself when you find a cracked heat exchanger. I would say this is an essential tool if u work on furnaces. Very clear picture quality & quality built battery life is solid. really only con is that the camera is too long for how I use it but that could be a pro for someone else. If you do furnace heat exchanger inspections this is a must buy !

This product is amazing and helped me as an inspector and my company so many times. It helps us create a visual for our client and also helps us see the unseeable. It does take some time getting used to controlling the feed but once you get the hang of it, then its not so bad. I highly recommend it.

I use this inspection camera for working on HVAC equipment. It works great for looking at heat exchangers, burner assemblies, ducting and more. It makes the inspections easier and without having to disassemble the system as much.
