I have been using this for a variety of reasons mainly using it to find thermal hotspots in my home but also for hunting. I will say that this thermal imager is exceptionally easy to set up and the app is actually pretty decent, the quality of the image is pretty high and it is pretty sensitive to heat , I'm able to place my hand on a wall and Pull It Away immediately and I can see my handprint for a few seconds through the thermal Imager. I am able to be about 30foot from my phone and still get good signal so that's awesome . As I stated I've been using this for looking at my walls see how the insulation is and I can very usually see where the warm spots are my home. But I can also use this for hunting on cool nights, when the nights are pretty cool and the ground cools down I'm able to spot animals using this Imager a good distance away. So my overall opinion is this is a great thermal imager it functions flawlessly and it is pretty compact so it is easy to always keep on you.

Alright for a basic, entry level thermal imager. Gets the job done, but by no means is remarkable. Sufficient for occasional home use.
Slow to boot. Small, low resolution screen. Solid feel and appears well made.
Note that the temperature range varies between models.

It really work！ I just did an experiment with it at home and it can actually detect cameras!

This little camera is a great value for the buck. I now own several that are being utilized as trail cameras and security on a small farm. I can depend on these cameras to perform well in all climates. Had several of them for a few years and they have out lasted my Mountie and several other “big” name cameras.

not with this security camera - you can choose between the cloud or install your own micro sd card for video files that are saved as 5-minute clips in mp4, timestamped and dated so you can easily transfer to your mac/pc and browse footage in real time instead of streaming it (this can be cumbersome on a poor internet connection). I have 6 security cameras from this brand that use the same app, so I can easily swipe between all the cameras in different locations. More information about the camera can be provided upon request if needed.

I've bought quite a few K&F Concept Surveillance Cameras so far and i have no complaints when it comes to setting these up. I have a mesh network at home so wifi signal is great at home. Set up is very simple. I wanted something that anyone could use via the app which i haven't had any complaints from any of the household members.

This outdoor security camera works where WiFi and electricity are not available. One can view your home anywhere and anytime.

Honestly, I can't find a better home security camera for the price
