Burglars like to move around in darkness so as not to be caught, if they suddenly find their criminality lit up for all to see, they will probably want to move on. Motion lights can also send motion-activated alerts to your phone where you can respond by sounding an alarm, again to scare off potential burglars.

Tempered glass is several times stronger than annealed glass. The glass is made in a way that enhances its strength and thus when used in windows, they are considered safety windows. This is because they make it much harder for a burglar to break in via your window due to the fact that the glass crumbles, making it more time consuming for the burglar to enter your home and more likely that they will get caught. Reinforced glass is therefore a security measure that also acts as a deterrent.
