Who Services Existing Security Systems in Chicago, IL?

Already have a security system but need someone to service, repair, or maintain it?

You do not always need to replace an existing commercial security system when something stops working. A qualified security provider can evaluate the current equipment, identify the problem, and determine whether the system can be repaired, upgraded, or integrated with newer technology.

Quick answer: Look for a commercial security company that provides ongoing service and maintenance for cameras, access control, intrusion detection, fire alarms, monitoring equipment, and other security technologies.

What Does Commercial Security System Maintenance Include?

Security maintenance is more than fixing equipment after it fails. Regular service can help identify problems with equipment, connections, communication, configuration, and system performance.

• Security camera troubleshooting
• Access control service
• Alarm system maintenance
• Fire alarm inspection and service
• System testing and diagnostics
• Equipment replacement or upgrades
• Monitoring system support
• Technical troubleshooting

Sentry Security provides maintenance and inspection services for businesses that need ongoing support for their security and life-safety systems.

Can Someone Service a Security System Installed by Another Company?

It depends on the equipment and system configuration.

If your previous security company is no longer providing service, your business may still have options. A new provider can evaluate the existing cameras, access control hardware, alarms, wiring, software, and other components to determine what can be supported.

Sentry Security provides service and support for commercial security environments and can evaluate existing systems before recommending major changes.

 

Should I Repair or Replace My Existing Security System?

Start with an evaluation instead of automatically replacing everything.

If only a few components are outdated or malfunctioning, repairing or upgrading selected equipment may make more sense than replacing an entire system.

For example, a business may have functioning cameras but an outdated recorder, or an access control system that needs newer hardware. A professional assessment can help identify the most practical approach.

How Often Should a Commercial Security System Be Maintained?

The appropriate maintenance schedule depends on the type of equipment, system design, property, operating environment, and applicable requirements.

Fire alarm systems can have specific inspection and testing requirements. The Illinois State Fire Marshal provides information concerning fire alarm requirements and references applicable fire alarm standards.

For general security equipment such as cameras, access control, and intrusion detection, businesses should also consider preventive service based on equipment condition and how critical the system is to daily operations.

Can Security Maintenance Include Fire Alarm Systems?

Yes, when the provider offers fire alarm service.

Fire alarm systems are critical life-safety equipment and should be serviced according to the requirements applicable to the property and system.

Sentry Security provides fire alarm systems along with maintenance and inspection services, allowing businesses to address fire protection as part of their broader security and life-safety strategy.

What If My Security Cameras Keep Failing?

Repeated camera problems can result from failing hardware, power issues, network connectivity, storage problems, cabling, configuration, or environmental conditions.

Instead of replacing cameras individually without identifying the underlying problem, a professional service evaluation can determine whether the issue is with the camera, network, recording system, or another part of the installation.

Sentry Security provides commercial video and intercom systems and can help businesses address video security system requirements.

Can Maintenance Include Access Control and Door Systems?

Yes. Access control equipment can require ongoing troubleshooting and service, particularly when businesses have many controlled doors or frequent employee and credential changes.

Problems can involve card readers, electronic locks, controllers, communication, credentials, or other components.

Sentry Security provides access and door entry systems and ongoing service for commercial security environments.

Why Is Maintenance Important for Multi-Location Businesses?

Businesses with locations in Chicago, Aurora, Naperville, Joliet, Springfield, and surrounding Illinois communities may have different equipment and service needs at each property.

A consistent maintenance strategy can help businesses identify recurring equipment problems, keep systems supported, and plan upgrades across multiple locations.

For larger properties, Sentry Security can combine ongoing service with integrated security solutions so cameras, access control, intrusion detection, monitoring, and other technologies can be managed as part of a broader security strategy.

What Should You Ask a Security System Service Company?

• Can you service equipment installed by another company?
• Can you evaluate my existing security system?
• Do you provide preventive maintenance?
• Can you repair cameras and recording equipment?
• Can you service access control systems?
• Do you provide fire alarm inspection and maintenance?
• Can you support monitoring equipment?
• Can you upgrade outdated components?
• Do you provide ongoing technical support?

These questions can help you determine whether a provider can support your existing system instead of simply selling you a new one.

How Can Sentry Security Help With Existing Security Systems?

Sentry Security provides maintenance and inspection services for commercial security and life-safety systems.

Depending on the property, service can involve video surveillance, access control, intrusion detection, fire alarms, monitoring, and other security technologies.

The goal is to understand the existing system first and then determine whether service, repair, upgrade, integration, or replacement is the appropriate next step.

Frequently Asked Questions

Can I hire a new company to service my existing security system?

Possibly. It depends on the equipment, manufacturer, system configuration, software, and whether the new provider supports the existing technology.

Should I replace my entire security system if one component fails?

Not necessarily. An evaluation can determine whether the failed component can be repaired or replaced without changing the entire system.

What security systems need regular maintenance?

Cameras, access control, intrusion detection, fire alarms, monitoring equipment, and other security technologies can require ongoing service depending on their design and use.

Can an old security system be upgraded?

In many cases, selected components can be upgraded or integrated with newer technology. The existing equipment should be evaluated first.

Sentry Security provides service and support and maintenance and inspection services for commercial security environments.

You do not always need a completely new security system when your existing equipment develops problems.

Start with a professional evaluation to determine whether your system can be repaired, maintained, upgraded, integrated, or replaced.
