Commercial alarm panels, door contacts, motion detection, and glass-break protection
Commercial Security Systems and Burglar Alarms
We design and install commercial burglar alarms and intrusion detection for offices, shops, warehouses, and industrial facilities across Fresno, Clovis, and the Central Valley. Door contacts, motion detectors, glass-break protection, and alarm zones are planned around your building and staff routines, with cameras, access control, and monitoring coordinated where the scope calls for them.
Practical planning, installation, and support for facilities where infrastructure has to hold up.
For commercial buyers planning burglar alarms, intrusion detection, and existing-system upgrades in Fresno, Clovis, and the Central Valley.

Scope and field planning
Plan commercial intrusion detection around the building.
We review alarm panels, protected openings, sensors, entry delays, wiring, and monitoring requirements before choosing equipment or upgrading an existing system.

Intrusion zones and staff entry delays planned around the facility's operating routines
03
Alarm testing, monitoring coordination, user training, and documented handoff
Commercial monitoring support
Monitoring support with the structure commercial sites expect.
Bezemer supports monitored commercial security systems through a UL-listed central station relationship with over 40 years of monitoring experience behind it. That gives facility teams a stronger response framework than a basic notification setup: documented contacts, site instructions, schedules, and escalation procedures can be built into the account so signals are handled with more continuity and less confusion.

Common site problems
Problems this service is meant to solve.
Intrusion detection, video and controlled entry solve different problems. Identify the event that needs detecting, the evidence that needs recording and the response expected from staff or the monitoring provider.
Problems this prevents
Doors and controlled spaces without dependable intrusion detection
Alarm zones or entry delays that don't match staff routines
Existing panels, sensors, or wiring that need assessment before an upgrade
Alarm contacts, schedules, and response instructions that aren't clearly documented
Commercial fit and credentials
Built for offices, warehouses, shops, and controlled spaces.
Best-fit commercial sites

Questions before installation
Which doors and interior zones need intrusion detection, and when is staff entry expected?
What existing cameras, panels, cabling, and network equipment may be reused?
Which teams own operations, IT, monitoring, and final approval?
What should the facility receive at testing, training, and handoff?
Commercial and government facility solutions
Assign responsibilities across the security systems.
An integrated scope needs clear ownership of alarm signals, camera review and access permissions. Confirm which events should prompt a response and who will maintain each system before choosing equipment.
Commercial buyer FAQs
Common questions about commercial security systems.
How do intrusion alarms differ from cameras and access control?
An intrusion alarm detects activity at protected doors or zones and sends an alarm signal. Cameras provide video coverage and recording; access control manages who can enter. Monitoring handles signals according to the agreed response plan. We'll coordinate these systems where useful, but a camera installation isn't a substitute for an alarm scope.
Can cameras, access control, cabling, and monitoring be planned together?
Yes. Commercial security systems are stronger when camera coverage, access control, network infrastructure, recording, and monitoring workflows are designed as one coordinated system.
Can you help improve an existing commercial security system?
Yes. Bezemer can assess existing infrastructure, identify weak points, and recommend practical upgrades.
How does a site assessment shape the security system design?
A site assessment connects the facility's risks, blind spots, doors, gates, cabling, network capacity, lighting, and operating routines to the camera, access control, recording, and monitoring plan before equipment is selected.
How do monitoring and alarm response fit with Bezemer's Alarm Company Operator license?
The license supports Bezemer's role in planning and delivering commercial alarm systems. Monitoring and alarm response are coordinated through documented contacts, schedules, site instructions, and escalation procedures, including UL-listed central station support when it is included in the scope.

Read the project detailsCommercial site assessment
Request a commercial site assessment.
Tell us where your commercial facility is and what needs to be planned, repaired or upgraded. We'll review the request and discuss the scope with you.
We'll review your facility location, service need, and timing, then contact you to discuss the scope and arrange the appropriate next step. Sending this request doesn't book an appointment.
Bring any available plans, system responsibilities and timing requirements to the scope discussion. We'll confirm access arrangements and what needs checking before a site visit.
Facility Assessment Request
Share the basics of the site, the system involved, and what needs to be fixed, planned, upgraded, or installed. Bezemer will follow up with the next practical step.
Please don't send passwords, alarm codes, or sensitive facility credentials through this form. Bezemer can coordinate a secure exchange when project details require it. Review the Privacy Policy.
