 #### HomeKit stalls or devices respond slowly with many cameras
 
 HomeKit updates each camera snapshot sequentially when there are multiple cameras on a bridge. The HomeKit update methodology can lead to the app stalling or taking a while to update. To avoid this problem, limit each `HomeKit Bridge` to 6 cameras and create a new `HomeKit Bridge` for additional cameras.
