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.

Used it for a week and it powered my Sony FX30 for whole day via USB C :)

For readers in a hurry, the conclusion comes first: Conclusion If you are aware of the safety, you can't go wrong with this camera. It is easy to use and has all the functions you need. Test report The power pack, drilling template, screws, dowels, instructions and of course the camera are supplied. Functions: The connection cable is permanently installed with the camera. This may be unfavorable if you want to lay the cable through a wall, so our products are battery-powered or solar-powered. Alarms are stored on the SD card, you can view them later in the app. The app is always required for configuration. You have to register there first. The easy configuration in the app is a plus. Motion and sound detection are possible. You can also set motion tracking, which also works, but the camera rotates horizontally and vertically. Depending on where the camera is mounted, 2 axes are actually required for motion tracking. The camera also has a speaker, you can talk through the app. That also works very well. However, you cannot limit your field of vision in advance, you always have a full field of vision. You have to be careful with outdoor recordings, since public areas are not allowed to be recorded. It is very good that the camera can be controlled via the app. Zoom works too. You can also have your cell phone alert you to movement or noise. It is important here that the app has the appropriate permissions. Night vision is good, with the integrated LEDs it can also illuminate the surroundings. Security: With such cameras that can be accessed via the Internet, you have to trust the manufacturer, because you cannot make any security settings yourself. One must also hope that the manufacturer will react quickly when security gaps are found and update the firmware.

A lovely pocket battery powered microscope it comes with travel bag, cloth and preprepared microscope slides. Good level of focus and zoom control means I can get a clear detailed up close view of things with my children.

☆☆☆☆☆☆☆ ☆☆☆☆☆☆☆☆☆}

Most new generation surveillance cameras are often round or very rounded in shape and white in color.
This is different here with the square cube with the chamfered edges and I really like the shape.
In addition, the color, which goes very well with our windows, doors, etc., is not as conspicuous as a white camera.

To start up, you have to install the manufacturer's app and create an account as usual and integrate the camera into the WLAN network.

The camera only supports 2.4GHz networks and if you connect the device (tablet or smartphone) on which you have installed the app to the 2.4GHz WiFi and follow the instructions in the app and the German manual, the setup is easy and done quickly.

The camera is attached to a wall etc. directly with the housing using screws which are then covered by silicone plugs.
It doesn't make sense for me to mount the camera rotated by 180°, but if this is necessary, you can activate "rotate the screen" in the app so that the image is not displayed upside down.

I really like that the live image in the app is displayed quickly and without much delay. With my much more expensive cameras (Arl..Ultra) I have a much longer delay and the picture is not much better with them either.

The app offers the usual options for setting up the camera and a clear display of the recordings on the micro SD card.

There is a power consumption statistic so in conjunction with the alarm and video settings you can find out the maximum battery life.

As usual, areas can also be marked in which no movement should be detected.

The recordings and the live image can be made with the resolutions SD or FHD. This is set with two clicks in the app.
The current WLAN strength and data transmission rate are also displayed there.
With SD it was about 20KB/s for me and with Full HD (FHD) up to 220KB/s.

The image was displayed very sharply and with high contrast with a slightly visible delay (1-2s).
The depth of field is impressive. Both an object positioned very close (approx. 30cm) to the lens and objects that were far away were sharply represented.
The digital 4x zoom works, but shouldn't be overestimated because of course details are lost as a result. If you want sharp pictures here, you have to opt for a camera with an optical zoom.

Using the app, the camera can be panned over a very wide area with a very short delay time. That's 355° horizontally and 120° vertically.
This gives you an all-round view and you can look at the sky or the ground.

What also worked very well was the motion detection with the PIR sensor, which is intended to only detect movements of people and not to record every movement of bushes etc.

In the alarm management, the detection sensitivity can be set in 10 levels.
In the "Alarm plan" periods are defined in which recordings are to be made
The live image from the camera is shown with the "Alarm area" item and overlaid with 144 squares (16 horizontally and 9 vertically). By activating the individual squares (which are clearly colored orange), you can define the areas in which the motion detection should be active.

One of three options can be activated under "Warning with sound and light".

"When motion or people are detected, the camera sends a warning with"
• Alarm with sound (siren)
• Alarm with light
• Alarm with light and sound

A sub-item in alarm management is the "alarm work mode".
Three options can be activated here.

1▪︎In energy-saving mode, the recording time is limited to a maximum of 10s and the detection of people is activated.
2▪︎In performance mode, the recording time is extended by detecting motion again.
3 ▪︎If the "Custom Mode" is activated, you have three options.
• Activate that only persons are recognized at night and/or during the day.
• The recording is made with 10 • 20 or 30 seconds
• Switch off the alarm interval or set it to 2 • 5 or 10 minutes.

The battery life is of course dependent on how many events are recorded. The longest battery life is probably achieved in energy-saving mode.
You can check this in the power consumption statistics and adjust the settings in performance mode accordingly.

The recordings were stored on a micro SD card with a capacity of 128GB. My card was recognized but had to be formatted in the camera. Therefore, you should back up the data on the card beforehand.

On the positive side, storage in the cloud has to be activated separately. According to the description, the free test phase is 7 days, which I did not use, although it makes sense.
If the camera is stolen, the SD card is gone and you have no evidence or pictures of the thief.
The videos are definitely stored more securely in the cloud.

I was surprised by the WLAN range, which allows a greater distance from the router compared to other cameras.
Here again comes the comparison with the Arl.. cameras, which - for me - have a much shorter range.
The stronger signal - for me - can probably be explained by the "improved 4 dBi dual WLAN antennas". However, other reasons cannot be ruled out.

The WLAN range as well as the picture quality is very good, the depth of field is great and if it's a bit dark and you want to see colored pictures, you can switch on the built-in and bright "headlight LED" with the app.
This can optionally also be activated when motion is detected and thus draw the attention of uninvited "guests" to the camera.

A not very loud but sufficiently loud siren can be activated for 30s when motion is detected and drives away - hopefully - uninvited visitors if necessary.
The built-in speaker is better for communicating with visitors than I've heard on other cameras.

Due to the relatively short test phase, I cannot yet judge the battery life in the current weather (with little sunshine) and thus the charging by the solar panel. In addition, the battery life is also dependent on many factors, so that the times determined by me cannot be regarded as a reference.

I rate the price-performance ratio as very reasonable.

In any case, the overall impression is so good that I can recommend the camera and rate it with a very good five stars.
It's one of the best cameras I've tried so far.

I say this is the first battery powered camera I've bought. I was skeptical but pleasantly satisfied.
It is made of materials that are comfortable to the touch and feel sturdy in the hand.
Movements that can be controlled via the app are smooth and precise.
The battery lasts a long time, and the remaining power is more than sufficient even on days without sun or rain.
The clip to be attached to the wall facilitates installation, the same applies to the solar panel.
I can absolutely recommend the purchase! !

Also can directly be powered by car battery.
