I really like to have (mic) audio input available with all my IP cameras but many outdoor cameras these days don't support an audio input (mic). Now that Ken has updated BI recently to support audio from one camera that uses a mic input to include the audio in multiple cameras that are installed close to the mic camera that do not support audio, this worked out to be great additional feature!
I took an old Sharx camera (the first IP camera that I purchased about 7 years ago) and installed it in my garage. It has the best input (mic) audio of any IP camera that I've ever had. The video from the camera is VGA and sucks but decided to utilize the audio with the new (re-branded) Dahua PTZ camera. The external mic attached to the old Sharx camera is mounted outside but under the garage eave, so it's protected from weather.
Just thought I would mention this in case someone has an old indoor IP camera that has great audio but lousy video. With BI, it won't go to waste.
