After the firmware update only 3 of my 4 cameras are working...they went on the blink after I applied the FW update to just one camera and then all the others no longer had the FW update button available next to them but they were just showing as being "Offline"...please fix

nofears,

Consider installing a fresh set of batteries in the one affected camera. Low or depleted batteries can result in a failed firmware update. After installing a fresh set, the camera may need to be synced back up with the base station and allow the firmware update to take place overnight.
