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...

I had a few cameras and they failed, but this one meets all my needs. The auto tracker is brilliant as it follows you and to me that's a huge deterrent to snoopy people. It also has 3 headlights that light up at night, so even better.
High quality images and works great with my phone app while on the go. The camera produced CCTV images within 15 m after being connected to the mains. We recommend.

Update, had a few glitches with the app but the support is fantastic. I contacted them via email and had a great experience with them. A new update fixed my problem.

Quality best inspection camera I ever own.

It allows me to mount m42 mount lenses on my Nikon 1 camera...there is no auto focus with it but it is very easy to get sharp photos...there is no glass in it so the optical quality of the lens used is not affected...this unit easily connects to my nikon one and my m42 lenses...the helios44_3 and the volna9...easy to screw on and off the adapter...the package is a week early arrived than expected and the price was amazing...this was one of the best values I've bought in a long time

In conjunction with the Canon EOS 1000 D Canon EOS 1000D SLR digital camera (10 megapixels, live view) housing, the maximum resolution can be achieved for this camera. Thanks to aperture values from 1.4, it is wonderfully possible to resolve the motifs in front of the background with absolutely crisp sharpness. In my opinion, the colors also appear more natural. Since I previously only worked with a Tamron zoom lens and this only starts with an aperture value of 3.5, you also have to get used to paying attention to the aperture with the automatic function or in program mode 1.4 of the Canon is not selected for "normal images", otherwise the depth of field is correspondingly small. The auto focus is quiet and fast, which is particularly helpful in twilight and with tracking auto focus. Can only recommend the lens.

am impressed with the quality of workmanship on this very affordable adapter, which is what you would expect from a high end product. My Nikon lenses fit the adapter like a Nikon camera body and connect perfectly to my Fujifilm camera bodies. This is a dumb adapter, meaning there are no electrical connections to the camera, so focusing has to be done manually and auto exposure is only available on aperture priority auto exposure. Given its limitations, I highly recommend this K&F adapter.

Needed an inspection camera / scope for some auto repair work. The Kentfaith fit what I needed without breaking the bank. Great value and easy to use. The 3' flexible camera cable was perfect or my needs. The screen size and resolution is more than adequate. A great addition to anyone's tool box. Recommended.
