The BTech 4K IP Calculator camera with IR recording and 10 h battery for complete indoor surveillance.
It is an everyday object we are all used to and do not pay much attention to when seeing it laying around in the home and office spaces. This calculator looks and works just like the usual one we see in supermarkets and office supply stores.
Hidden inside is an A/V DVR that offers 4K and 1080P recording options. It is an IP device, which means that you can connect it to your router and access the feed from anywhere in the world with an internet connection on your smartphone.
The App offers many functions for controlling and calibrating your device.
Multiple people can access the device via Wi-Fi at the same time. However, when you connect your device to IP, the only way for another person to access the feed is if you share the invitation via QR code (in App) or email account (also in App). The person you share it with can then access all the functions in the App as you, and access the live feed as well.
The App also allows you to share the logs with colleagues, friends, or family. It can be easily shared via social media in just a couple of clicks. However, it can only be shared when the device is connected via IP. When accessing the device on the same network without an IP connection, the files will not reach you.
In-App you can rotate the camera, you can choose two ways to turn off the LED lights of the DVR that are already very well hidden. That way you can make sure that no one will accidentally stumble upon the fact that the device is a covert IP camera.
Scheduled recording is available, and motion detection as well as continuous recording mode. The battery status of the device can also be seen in the upper corner of your live feed.
The user manual is provided with the device, and it is available in the App.
