The camera functions well as a smartphone baby, pet or elderly parent monitor or as part of a complete home/office security system with remote internet monitoring ability. The FI9821W V2 improves on the FI8910W by adopting high performance media and video processors capable of H.264 video compression which allows for ultra-smooth high definition video transmission, increased FPS and minimal bandwidth consumption. In addition, due to the small file sizes produced by H.264 video compression it has the ability to save tremendous disk space when doing video recording.
