 ## Notes on Cameras
 
-Cameras are a complicated situation. If you are running the [Docker way](https://github.com/NRCHKB/node-red-contrib-homekit-docker) then FFmpeg will be preinstalled for you with several of the options preset (may not have all hardware accelerations built).

 For those writing examples, please include how you have installed FFmpeg (including any special build flags)!
 
 It is recommended use "Accessory" as the Host Type for cameras. The camera should be the "parent" service with "motion" and "doorbell" (if used) as linked services.
