I’ve installed Avast Anti-Theft on my Sony Xperia Z3 and tried if a picture is taken when the wrong password is entered more than 3 times. But I just received the following e-mail:
The password check on device D6603 was violated. Unfortunately, your take-a-picture request could not be performed (possibly there is no front camera available on your device).
The device has a front camera. I also tested this with the AVG antivirus app the picture was taken there. I’ve also collected the logcat output: http://pastebin.com/atBG50z0
