What is the battery running time of the counting device?

The running time of the battery depends on the device. Therefore no authoritative statements are possible. Intests we have tested several 7 inch devices where the battery lasted about 9 hours. 2 counting intervals of 2x4 hours can as a rule be covered. Generally we would recommend giving the counters external batteries. You can buy these with a large capacity for a reasonable price.Phone us up, we are happy to advise you. 

Can I use my own mobile/tablet for the survey?

The basic requirement for the use of your own mobile is Android. A version for iOS is not available at the moment but planned. In the past two years of testing we have used several makes of smartphone. The use of the app was possible on all of them without any problems. As we cannot guarantee the function on all smartphones we recommend that you download the application from PlayStore and test it on your own mobile.

On a screen up to 6 directions can be recorded with Vzapp®.  In our tests devices with a 7inch screen size were reliable. In principle screen sizes from 4-10 inch are fine depending on the user.
