Security for your home and your privacy
Unlimited armed-guard response (no false alarm fees!)
Verified monitoring and direct emergency response.

Verified alarm monitoring is the only way to get direct police response in case of an emergency. Unlike many alarm companies, we activate and encourage the use of security monitoring technology that allows for over-the-panel response in the event of an alarm. This is because, in Clark County, Nevada there is a “non-response” policy due to limited emergency resources. This means Metro, North Las Vegas and Henderson police won’t respond to an alarm unless the emergency dispatch agent can verify there is an actual emergency taking place, and not the common false alarm from user error or malfunctioning equipment.
