A burglar alarm monitoring apparatus to activate a digital camera to take pictures includes a body, a receiver, an actuation means and a monitor device. The body has a housing chamber to hold the digital camera. The monitor device can detect intrusion of burglars and generate a detection signal which is sent to the receiver to trigger the actuation means to activate the digital camera, and then the digital camera starts taking pictures or video recording. Thus the digital camera can provide burglar alarm and monitor functions and has greater practicality.
