In a time when you can buy home security cameras off the shelf of your local big box store, why would you want to go the route of a professional home security provider? In a word, connections. A professional home security integrator has the ability to connect their home security cameras to your new or existing security system and all of its components. Those components can include your intrusion detection (i.e. motion-triggered alarm), smart locks on the doors, video doorbell and more.
