Choosing a commercial security company is about more than buying cameras or an alarm system. Businesses need a provider that can understand the property, identify security risks, design the right system, install it properly, and provide ongoing support.
Quick answer: Look for a commercial security company that can provide the services your facility actually needs, including access control, video surveillance, intrusion detection, fire and life-safety systems, monitoring, visitor management, system design, maintenance, and emergency communication.
What Services Should a Commercial Security Company Provide?
| Service | What It Helps With |
|---|---|
| Access Control | Controls who can enter protected areas |
| Video Surveillance | Monitors important areas and records activity |
| Intrusion Detection | Detects unauthorized entry |
| Fire Alarm Systems | Supports fire detection and notification |
| Security Monitoring | Provides ongoing alarm and security event monitoring |
| Visitor Management | Controls and tracks visitors and contractors |
| System Design | Plans the security system around the property |
| Maintenance | Keeps security equipment operating properly |
1. Access Control
Access control manages who can enter specific doors, rooms, floors, gates, or restricted areas. Common options include key cards, mobile credentials, electronic locks, PINs, and biometric security.
See Sentry’s access and door entry solutions.
2. Video Surveillance
Commercial video surveillance can monitor entrances, parking areas, loading docks, inventory, restricted spaces, and building perimeters.
Sentry provides video surveillance solutions, including IP video, CCTV, analytics, remote access, and integrated video.
3. Intrusion Detection
Intrusion detection helps identify unauthorized entry, especially when a property is closed. Systems can include door contacts, motion detection, glass-break detection, perimeter protection, and panic devices.

4. Fire and Life-Safety Systems
A commercial security provider may also need to understand fire and life-safety requirements applicable to the facility.
Sentry provides fire alarm systems and related solutions for commercial environments.
5. Security Monitoring
Installing security equipment is only part of the solution. Businesses may also need ongoing monitoring for alarms and security events.
See Sentry’s security monitoring services.
6. Visitor Management
Visitor management helps businesses control and track customers, contractors, vendors, and other visitors. It can also work with access control to provide temporary or restricted access.
Explore visitor management solutions.
7. System Design and Engineering
A good security system starts with good design.
The provider should evaluate entrances, restricted areas, cameras, alarms, existing equipment, building operations, and future expansion before recommending technology.
Sentry offers system design and engineering services.
8. Maintenance and Service
Security systems need ongoing maintenance, testing, repairs, and upgrades.
Ask whether the security company provides ongoing maintenance and inspection services after installation.
9. Integrated Security Systems
The biggest advantage of using one integrated security provider is that different systems can work together.
For example:
- Access control can work with video surveillance.
- Intrusion alarms can trigger security events.
- Visitor management can work with access control.
- Security systems can support remote management.
- Emergency communication can connect to broader safety procedures.

A commercial security company can design, install, monitor, maintain, and support security systems such as access control, video surveillance, intrusion detection, fire alarms, and visitor management.
