This is not an astronomy camera, it's a general purpose battery-powered, image-stabilized audio/video color camera. It communicates with your smartphone or tablet via WiFi. I dreagged out a rescued-from-the-trash 102mm el-cheapo refractor, clamped the camera on its eyepiece, and quickly focused on a fake windmill three miles away. I also tried shooting right into the low-angle sun glare in the ocean and the camera didn't blink (like I did)--the automatic gain control took it in stride. Mind you, the telescope made things seem close, not the camera--all it does is replace your eye. This is good because that means you can clamp it onto anything you might look through, such as a riflescope or microscope, or even just point it out the window. Set up is a little fiddly, but if you've hooked up a camera with its own WiFi hotspot it will be a snap. Select the camera wifi hotspot in your camera's settings and then use the app. In short, if you like cool stuff, this is well worth the money.

The solar powered Surveillance camera is very good due to the portability. Detection is quick and video quality is good. Other reviews have had problems with the camera on their WiFi network. As long as there is a good strength WiFi signal and your upload speed is above 2 mbs there should be minimal problems.

I think I've found the ultimate security camera. Bought this camera after a friend of mine recommended this brand. He is a photographer and has used some of their products in the past and seemed very happy with them. After a few hours of research, this camera seemed to be the only one that had all the features I was looking for, so I figured I should give it a try.
Just like the specs, you get everything they claim. The camera has a built-in high-capacity battery, so you will never run out of power. This is also guaranteed by the solar panel that you bring together. Both are waterproof and suitable for outdoor use, which is amazing.

When it comes to storage you have a micro SD slot that supports up to 128GB or if you prefer you can store your footage via the cloud service. Obviously you would have to pay a monthly fee.

However, what I like the most is the pan/tilt/zoom feature, which allows you to control a very large area remotely from the mobile app. The footage is in 1080p, so it's very clear even with night vision. Another great feature is the PIR sensor, which is optimized to reliably detect humans and large pets, and you can change its sensitivity in the app too. Night vision is both black and white and color thanks to the floodlights installed on the front of the camera.

Connectivity is via your WiFi. So if you are planning to buy more than one camera, you need to make sure during installation that they are within your WiFi range and have a strong signal, otherwise they will not work properly. Or you can buy a WiFi extender.

The app that controls the device is very user friendly and easy to install for the less tech savvy. And you can basically control everything from within. You can share the device with other people, check the battery status and change the energy saving settings. Change Motion Detection Sensitivity You can take screenshots or record videos whenever you want. You can even set time periods for the camera to detect motion and record videos. Basically everything you can think of is in this app.

The only downside I could find is that it's a bit pricey. I've used a few RING cameras in the past and they've been really good and a bit cheaper. But none of them had all these functions. So if you're looking for a security camera that has it all and is willing to pay the price for it, this is probably your best bet.

I was looking for a good surveillance camera to keep an eye on my car. Now I have found it. The camera is battery operated and recharges itself through the solar panel. The installation is therefore very simple, without annoying power connection. The image quality is exceptionally good. In addition, the camera has a motion detector & is swiveling, ie you can always look who just rings at the front door.
All in all, I am very convinced of the surveillance camera and am already thinking about getting a 2nd.

I am very happy with the K&F Concept surveillance camera. The supplied solar panel in particular ensures that the battery life (at least in summer ;)) is really great.

Perfect for outdoor surveillance, this 4g camera doesn't require wifi and runs on solar power. It's wireless and easy to install, making it a great choice for remote locations.

The night vision device works without any problems and can be operated by everyone. Battery is included. Very positively surprised by the 7 different brightness levels.

I bought this camera to monitor my garage driveway and especially with the flexible rotation it is well suited for this area. The picture quality is very good and the night vision function works as it should. You can recognize the people in both modes.
Personally, I don't actively use the floodlight, but it also works when a person is detected.
And now the best: The camera always has enough power thanks to the solar panel, and in the 5 days I used it, the battery was never below 80% - so it shouldn't be a problem even on dark winter days. The only important thing to know is that the camera needs an active WiFi connection to work, which is why you can't turn off the WiFi overnight.

A few small shortcomings that you have to accept with such a good camera are the lack of an RTSP address, no USB C, and unfortunately the camera cannot follow and track people once they have been detected. Maybe something will be added via an app update.

All in all a recommendable surveillance camera
