Photo samples of Raspberry Pi Camera Module Pi NoIR, without and with Hoya R72 Infrared filter. All photos resized only, added with black frame and text, no any other touch up.
It seem that the photos using Hoya R72 filter are little blue, may be misfocused for infrared!
The Raspberry Pi 2 installed xrdp, such that I can remote login from mobile phone.
On the Android phone, I use free aRDP: Secure RDP Client.
Once Raspberry Pi boot-up and connect to Android hotspot, Run aRDP on Android phone, and run the simple "Python program to capture image from Pi Camera Module".
