Good pictures

Overall, the camera is very well made, but I doubt that it is really waterproof. Personally, I would advise against installing it on an outside wall, possibly even putting it under a rain gutter to protect it from water, for example. The installation and thanks to the app is child's play and the functions advertised in the offer work perfectly. The image quality in night vision mode is perfectly adequate. Price-performance ratio, I think that there are cheaper options for outdoor use that are really suitable for this.

The inclusion of a sim card slot in this 4g camera allows for seamless connectivity and remote monitoring. No more worrying about Wi-Fi signals or internet outages!

High Quality - Versatile - Modern - Analysis - Waterproof - Borescope Camera

The Industrial Borescope, Digital Borescope Inspection Camera 1080P HD comes in a small and beautiful package and is well padded.
The delivery includes the endoscope, micro USB charging cable and instructions in German and English. The endoscope camera is very high quality and well made.
It comes preloaded so you can turn it on right out of the box. In order to use it, you have to set the toggle switch to On. The camera boots up in just a few seconds. The LCD display shows the scanned image in color. The camera has a resolution of 1080p and can take photos in three different resolutions. The cable of the endoscope is 4.5 meters. Furthermore, the endoscope is waterproof with IP67. The storage capacity of the endoscope is 2600 mAh. If the battery is empty, it can be charged with the supplied micro USB charging cable. I'm still very happy with it.

Makes a high-quality impression. In HD, the videos are in good quality. Battery always has 100 percent through the charging panel. Motion detector has a good response time. Motion notification comes immediately to the phone.

When I was looking for a surveillance camera, I came across this LTE camera from K&F Concept.

Two points were decisive for me:
1. The camera should be able to be operated without an external power source.
2. The camera should have online functions.

On point 1:
The 4G camera has a built-in battery. The battery can be charged using the included cable. In addition, a solar panel is included in the scope of delivery, which can be attached directly to the camera or to the wall of the house. In the past few weeks it has been relatively sunny and the battery was always fully charged thanks to the solar panel. I'm curious if that will also be the case in winter.
To point 2:
The camera has a SIM card slot. A sample SIM card is included in the scope of delivery.

The camera can be rotated 355°/ 100° in two directions in the app.
The camera offers a good picture (2K) both during the day and at night.
The two-way sound is acceptable, but depends on where / how high the camera is mounted.

So far I am very satisfied with the product.

This wireless outdoor security camera works where WiFi and electricity are not available. With a NANO SIM card, the camera will only activate when it detects a moving object. This reduces data consumption.
The schedule function (UBox APP ) only activates the camera when required and saves unnecessary notifications.
With an SD memory card you can bypass the paid cloud use.

When I said "1000x magnification" I was skeptical before I bought it, which turned out to be true. The real maximum magnification is more like 500-600, which is perfectly sufficient for my purposes - checking solder joints in the hobby area. The lighting is bright enough, but is reflected in the picture on smooth surfaces. The display resolution is sharp, noise and flicker-free. The menu navigation takes a little getting used to, but with a bit of experimentation you will quickly reach your goal. I'm still puzzled as to what the "Motion detect" function on a microscope is for when looking at objects that don't move by themselves? The English menu navigation does not say "Motion detect" but "Exposure Compensation", i.e. exposure correction, which makes more sense. The translation of the menus leaves a lot to be desired not only in German but also in English. The battery capacity is sufficient for at least 2 hours even in continuous use with lighting, but the battery indicator only shows 2 out of 3 bars after a few seconds even when the battery is fully charged. The mechanics of the tripod is simple but stable. All in all, the product serves its purpose for me and I am satisfied with it.
