These days CCTV technology is quite remarkable and very affordable. 

Most systems will allow you to view your camera images on your phone that can be seen anywhere around the world. Only by you or your family I might add!

The images are very clear, time dated for police reasons, if necessary, can send you notifications to your phone or computer if you choose and of course all recorded if your premises is accessed by criminals. 

Keep an eye on the pets, look out for arriving guests, monitor doorbell rings etc.
