You can easily make laser security system.  To make this system I am using LDR (light dependent resistor), one Laser, 5 volt Relay, Variable resistor, 1.6k resistor and one siren light.

    Can work as a toy, certainly not as a security device as the receiver can be fooled by any LASER pointer. To be really secure, such a device MUST modulate the LASER AND compare what is sent to what is received.
