Commercial Alarm Systems
A professionally installed commercial alarm system provides protection beyond simply sounding a siren.
St. Louis Alarm Company installs monitored intrusion detection systems designed to identify unauthorized entry and communicate alarm events to a professional monitoring center 24 hours a day.
Commercial alarm protection can be configured for entrances, offices, warehouses, equipment rooms, inventory areas and other critical portions of your facility.
Depending on your property, protection may include door contacts, motion detectors, glass-break sensors, overhead-door contacts, panic buttons and other specialized security devices.
24/7 Commercial Alarm Monitoring
Your business doesn’t stop needing protection when your employees leave.
Our professionally monitored commercial security systems provide 24/7 alarm monitoring, helping protect your property nights, weekends and holidays.
Modern cellular communication can also eliminate the need to depend solely on a traditional telephone line for alarm communication.
With remote security management, authorized users can arm or disarm the system, receive alerts and monitor activity from virtually anywhere.
Commercial Security Camera Systems
Video surveillance has become one of the most important components of a modern business security system.
St. Louis Alarm Company installs professional commercial security camera systems in St. Louis for businesses that need reliable video coverage of their facilities.
Camera systems can provide surveillance for:
- Building entrances
- Parking lots
- Warehouses
- Loading docks
- Inventory areas
- Cash registers
- Offices
- Manufacturing floors
- Exterior perimeters
- Gates and driveways
- Apartment common areas
- Equipment yards
Our systems can include high-resolution IP cameras, AI-powered analytics, night-vision technology, panoramic cameras, license plate recognition and other advanced surveillance technologies.
Unlike consumer camera systems, professionally designed commercial surveillance systems can be engineered for continuous operation, centralized recording and expansion as your business grows.
AI Video Surveillance for Businesses
Modern security cameras can do significantly more than simply record video.
AI-enabled surveillance technology can help distinguish important activity from routine movement and provide more useful alerts.
Depending on the equipment and application, video analytics may be configured for functions such as:
- Human detection
- Vehicle detection
- Perimeter protection
- Intrusion detection
- Line-crossing detection
- Loitering detection
- License plate capture
- Smart video search
- Remote video verification
This technology is particularly valuable for warehouses, construction sites, equipment yards, dealerships and other commercial properties with large exterior areas.
Commercial Access Control Systems
Keys can easily be lost, copied or never returned by former employees.
A professionally installed commercial access control system gives your business greater control over who can enter your building and when.
St. Louis Alarm Company installs access control solutions for offices, warehouses, apartment buildings, retail locations, industrial facilities and other commercial properties.
Systems can support:
- Key cards
- Key fobs
- Mobile credentials
- PIN codes

Administrators can quickly remove an employee’s access without replacing locks or collecting physical keys.
Access control can also be integrated with other security technologies to create a more complete building security solution.
Integrated Commercial Security
Managing separate alarm, camera and access systems can make security unnecessarily complicated.
St. Louis Alarm Company can design integrated commercial security systems that bring multiple security functions together.
Depending on the system configuration, businesses can manage security through a centralized platform that may provide control over:
Intrusion Alarms
Monitor doors, windows, motion detectors and other intrusion devices.
Video Surveillance
View live and recorded security camera footage.
Access Control
Manage employee credentials, doors and access schedules.
Automation
Control compatible locks, thermostats, lighting and other connected devices.
Notifications
Receive alerts for alarms, access activity and other important events.
This can be especially useful for business owners and property managers responsible for multiple buildings or locations.
Multi-Location Business Security Systems
Managing security across several locations shouldn’t require several completely different systems.
St. Louis Alarm Company provides multi-location commercial security solutions that can simplify security management across multiple facilities.
Centralized security management can help owners, managers and corporate security personnel monitor multiple locations while maintaining individual permissions and security configurations for each facility.
We work with businesses operating locally as well as organizations with facilities in multiple states.
Security Systems for Warehouses & Industrial Facilities
Warehouses and industrial properties often require a different security strategy than traditional offices or retail stores.
Large buildings, overhead doors, loading docks, equipment yards and extensive exterior perimeters can create unique vulnerabilities.
Our warehouse and industrial security solutions can combine:
- Commercial intrusion detection
- Overhead-door monitoring
- Perimeter security cameras
- AI video analytics
- Access control
- Gate control

Whether you operate a small professional office or a large corporate facility, your security system can be designed around your building and workflow.
Video Alarm Verification
Traditional alarm systems detect activity. Video verification can provide additional information about what caused an alarm.
For applicable commercial properties, video alarm verification can combine alarm events with surveillance technology to help monitoring personnel evaluate activity associated with an alarm.
This technology can be especially useful for:
- Warehouses
- Equipment yards
- Auto dealerships
- Construction sites
- Vacant buildings
- Industrial facilities
- Outdoor storage facilities
- Commercial properties with large exterior areas
Ask St. Louis Alarm Company whether video verification is appropriate for your facility.
Commercial Fire & Environmental Monitoring
Security isn’t limited to burglary protection.
Businesses may also need protection against fire, carbon monoxide, water leaks and damaging temperature changes.
Depending on your facility and applicable requirements, we can provide monitoring solutions for:
- Smoke detection
- Carbon monoxide detection
- Water and flood detection
- High/low temperature monitoring
- Equipment-area monitoring
Commercial fire-alarm requirements vary by building and jurisdiction. Required fire-alarm systems should always be designed and installed in accordance with applicable codes and requirements of the local authority having jurisdiction.
