Our Work in Los Angeles

We don't publish client names or addresses. These are real Los Angeles jobs, described so you can see how we'd approach a property like yours.

Grocery Store Camera System Rebuild

We rebuilt the camera system at a grocery store in Los Angeles. The old recorder could show live video but had stopped recording, so we replaced it with a Dahua hybrid recorder and swapped out two cameras that had failed. Then we added a 32-channel recorder with 24 new 4MP night-color cameras and a 180-degree camera across two floors, powered by three PoE switches and two 8TB drives. We finished by setting the system up in Dahua's mobile and desktop apps.

Warehouse Burglar Alarm System

We installed a new burglar alarm system at a lighting company's warehouse in Los Angeles. A DSC control panel reports over an LTE cellular communicator, and the keypad has a built-in receiver for the wireless sensors. The system includes a wireless door contact, a wireless motion detector, a roll-up door sensor wired to a wireless transmitter in a weatherproof enclosure, and a 15-watt siren. We finished by setting the business up on the Alarm.com app.

Nonprofit Door Access and Intercom Upgrade

We rebuilt the door entry system at a nonprofit in Los Angeles. The magnetic lock on the main entrance had stopped working, so we replaced it with a new 600-pound mag lock. We also replaced the access control keypad, the color video intercom camera and two power supplies, with backup batteries for the power supplies.
