Hi
@estore009 sorry I took so long to get back on this.
I used the original SD card in my home IP camera and it worked for the past month, so doubt it is an issue with that particular SD card.
I tried a 2 other SD cards with the B1W, and when I first turn it on it takes about 3-5 seconds before I get the "please insert SD card" warning. The LED light is constantly solid green (not blinking) during this time, and the firmware files are still in the SD card after this (i.e. it wasn't pushed onto the camera). I tried reformatting the various SD cards using your instructions above using both Windows format and GUIformat. So am quite sure at this stage that it isn't the SD card.
Any tips at this stage?
