Camera Surveillance Systems

Don’t settle for short "cloud" based video clips, get 24/7 recordings and remote access via your smart device

Scheer Security has been installing commercial alarm systems and residential systems since 1979. The basics of detecting an intruder entering your premises has not changed much in the last 30 years: place a device at every possible point of entry, add interior coverage and monitor it, however, the detection devices and the panels that control them have changed dramatically.

Residential & Commercial Alarms


Unlike the mass marketers with cookie cutter systems, Scheer Security will customize a system for your needs.  Customize your alarm, customize your security and customize your notifications. Scheer Security has a security solution for any residence or business.
Whether it's added outside protection (outdoor photo beams/outdoor motions), fire protection, motion detectors, water detection, glass break detection, heat detection and even alarm security screens (which allow the window to be open yet the screen still be alarmed)   We install, service and monitor wireless and hardwired/hybrid systems.  We take pride in one installation at a time. 


The wire to your house is vulnerable to being cut or disabled, this is why more and more people are switching to cellular communication. Not only does  cellular makes your communication more reliable, it eliminates all the phone line troubles and hassles when 

switching phone line providers and finding a carrier that is compatible. In addition, the system will support remote interaction with your alarm via smart phone.  Remotely arm/disarm the alarm, turn lights on/off and even control your thermostat.


Not only does this provide peace of mind, but you may also get additional home owners insurance discounts for having a monitored alarm (ask your agent about the discount they may offer).  Your system is monitored via our central station 24/7 for any event that may be generated. Burglary, fire or medical, we will attempt to call the premise and then dispatch the proper authorities depending on the signals received. we have on-call technicians available 24/7, if after hour emergencies arise. 

Alarm Systems
Home automation has been a dream of science fiction writers since the 19th century and a crowd pleaser at World’s Fairs since the 1930s, but it didn’t start to be practical for ordinary homeowners until the 1990s. Scheer Security has been installing home automation systems for 20 years. Today the systems are robust and allow many options.

In today’s world, camera surveillance systems have become an everyday household item.  Scheer Security has been installing quality commercial and residential surveillance systems for over 20 years.  With very user-friendly video management software (VMS) that can be effortlessly accessed by multiple users from a variety of locations.  Not only do we offer installation, service and maintenance, we also offer a camera check in service.

Custom Surveillance Systems

We specialize in commercial camera surveillance systems, which  include LPR’s (license plate readers), or PTZ’s (pan,tilt,zoom), and the  typical fixed camera. We customize each system depending on your needs by offering a complete end to end solution.  

Residential Surveillance Systems

Residential surveillance systems have become more common in the past few years. Our  systems are designed using cameras with the  proper pixel count and lens configuration to provide you the best picture for  your needs.

License Plate Reader (LPR) Systems

Not all cameras are designed to capture license plates, this requires a certain kind of camera (LPR-license plate reader).  These LPR cameras can work with special software to keep a license plate data base which works great in gated communities, private parking lots and many more applications.

Doug Scheer

Doug Scheer was born in Cincinnati, Ohio. His father’s job took the family all over the country and even overseas; Doug graduated from high school in Fremont, California. He moved to the Los Angeles area at 18 and started Scheer Security a year later.

Scheer was one of the first automated central stations to monitor alarms in Los Angeles. While central station monitoring is still part of Scheer Security, Doug has seen the industry change from the old dry cell battery alarms with key locks for arming and disarming, to fully automated systems controlled via iPad.

Doug returned to the Bay Area in 1989 and moved to Oakley in 2004 with his wife and sons. They bought the property at 3460 Main Street for their business. The lot behind it is home to Boy Scout Troop 152’s annual Christmas tree sale.

Doug Scheer is a past president of the Oakley Chamber of Commerce. He currently serves on the Ironhouse Sanitary District Board.
