I've been having this camera on our construction site for a few months now.
Battery - stayed at 100% since then with the help of solar panels.
Nightvision - clear without almost no light in my area. Built-in light can be useful too.
Mic - The 2-way audio works quite loud (much louder than a speakerphone on a mobile).
Data usage: I got a 30GB plan for 90 days. With daily camera viewing several times a day it hasn't used even 1GB yet. I think more power could be used if we use the built-in light and record many videos. For live viewing, data usage is very minimal.

I wouldn't recommend if you want to move this into a WiFi network later, as this works only with a SIM card.

Anyone currently thinking about buying a game camera will be bombarded with a wealth of advertising promises on the Internet. Low light, no light, Bluetooth, WiFi, trigger times of 0.2 seconds - 0.4 seconds, etc. With an app or WiFi or without!? With the abundance of material, it is difficult to choose...! I will simply start with my conclusion after using the 4K game camera from K&F Concept for a little over a week. The images during the day are absolutely top-notch. The night shots look much better from a distance than the previously somewhat "grainy" cameras. A very decent hunting camera for this price range that meets all requirements to full satisfaction. The day shots are of an excellent nature, the night shots at close range up to a maximum of 12 meters are very good and absolutely suitable for showing off. Great camera with excellent recording performance, new housing type and, as I said, very homogeneous control in terms of the app.

Got this camera to spy on my cat and other animals in our backyard. It works great for wildlife too because those animals don’t see you anywhere near but you can see and hear them, and also capture them on video and take pictures of them. Works with solar batteries and requires no actual batteries or wiring. Great invention!

really love this LED Light personally! When purchasing, I was just looking for an LED light for me to take better pictures in dim lighting conditions. But after receiving it, I immediately fell in love with it! IT IS SO CUTE! The package is like a tofu and I really like the design: big text on the back, and the orange-yellow knobs on the side. The knobs have clear feedback at each location and I can really see all the different light that I easily control! I was also surprised by the 21 interesting lighting effects. They are so vivid! I kept playing with it for an hour and the joy it brought to me was way more than just an LED light. It made my day!

What an incredible battery! Whether it's to power your camera... a small LED light (I used it on a USB-C folding panel, nickel) or any accessory on a shoot (of course it charges a phone) it works really well! K&F becomes a real reference in this field

This is a pretty cool little doohickey. I’m sure it has lots of practical applications for mechanics and repair people. As for me, I can use it to look behind and under appliances, furniture, inside vents, etc. Not the most straightforward instructions, but here’s all you have to do: 1) Put the inskam app on your phone. 2) Set your WiFi to use the “inskam” network. 3) Plug the endoscope into the wireless transmitter. 4) Hold down the power button on the wireless transmitter for 3 seconds, until it lights up. 5) Use the switch on the endoscope cable to adjust the brightness of the camera light. 6) Open the app on your phone and start viewing! You can even take pics or video. There’s definitely a learning curve in terms of how close you should get to the items you’re viewing, and in how to manipulate the cable, but with some practice, you’ll catch on. Pretty cool!

light weight and led light vs warm light

Transmitter unit uv index quit working. Tech Support was very helpful. and timely. i would email a question and by the next morning i had a response. they continued to work with me until it was determined that the uv part of the transmitter was not working. they mailed out a replacement and i received it within a week. the new transmitter fixed the problem. it was nice to find a company that polite and responsive.
