It’s possible. I took some decent photos at a concert. 

Like any other filter, this one protects the front lens from water splashes. 

Check your lens thread size which is beside a "ø" (diameter) symbol. Order this filter of the same size. 

Thanks for your question. The monitoring data of the past two years will be stored on the APP. ""Day"" in the graph will display the average value of the data monitored by the detector every hour in the last 24 hours. ""Month"" in the graph will display the average value of the data monitored by the detector every day in the past 30 days. ""Year"" in the graph will show the average value of the data monitored by the detector in each month in the past two years. You can also export the data you need directly through the APP.
