Security system which includes motion detectors connected to cameras which are connected to a computer which is connected to a data communication device that informs a homeowner off-premises, the police, fire department and/or private security firm of the existence of an intrusion condition based on the images obtained by the camera. The motion detector detects motion in the field of view of an associated camera which then obtains images. A processor connected with the camera derives a silhouette of an object that triggered the motion from the obtained image(s). The silhouettes are compared to previously obtained silhouettes, such as those of various animals and humans having different sizes. A classification of the silhouette is obtained and depending on what object the silhouette is determined to correspond to, i.e., its identification, further action or countermeasures is taken. Control of the security system may be via a handheld telecommunications device.
