Guardian National Security: Protecting Residential Neighborhoods in Lake Los Angeles, Quartz Hill, and Del Sur with Reliable & Affordable Private Security Guard Services

We often encourage HOAs and other residential clients to take preventative measures to ensure that they don’t open themselves up to crimes of opportunity. That’s because everywhere there are career criminals who are on the lookout for an open window, vacant home, cracked gate or otherwise vulnerable property.  Guardian National Security can supply private security guards who can patrol your Lake Los Angeles, Quartz Hill or Del Sur neighborhood in a vehicle, gate guards who can control property access and standing guards who can provide assistance in the event of an emergency or activated alarm. Call today and we’ll go over the options for customizing our guard services for your needs.

Private Security for Quartz Hill, California, Aerospace Companies, Industrial/Manufacturing Facilities, Warehouses and More

Located in the High Desert of California, just north of the Los Angeles area, is Quartz Hill which used to be known for its agricultural products, such as almonds and alfalfa. More recently, however, due to growing concerns over water, much of the workforce has transitioned from agriculture to aerospace. To address the security needs of this ever-growing industry as well as other industries present in the area, Guardian National Security offers quality private security services at very affordable rates. Our security services in Quartz Hill can include incident reports, 24-hour guard services, front gate/door access control, material watch logs, fire watch, visitor escort, foot patrols, vehicle patrols, parking enforcement and more. To improve the effectiveness of our guard services, we offer motion sensors and “no trespassing” signs at no additional charge. Call today for a free quote.

Private Security Services in Lake Los Angeles & Surrounding Communities in LA County

In addition to our private security services for aerospace and industrial facilities, we also offer exceptional security guard services to civic centers, schools, hospitals, restaurants, construction sites, gated neighborhoods and businesses/residential sites of all sizes. Our security services are available throughout Los Angeles County, and extend all the way out to Lake Los Angeles on the eastern edge of the Palmdale/Lancaster area. In every case, business owners and residents can trust us to deliver highly dependable private security services 24 hours a day. Our diverse security services include property access guards, building lock-up and alarm, alarm response, parking control, logistics and event security (perfect for the Quartz Hill Almond Blossom Festival, and other private or public events in and around Lake Los Angeles).

Security Cameras, Alarms and Motion Detectors 

In addition to guard services, Guardian National Security is also qualified to install wireless surveillance cameras, alarm systems, motion detectors and other low-voltage security equipment.
