Open an electronics store or browse a smart security website, and you’ll quickly find self-installed cameras and video doorbells. The appeal is obvious. They cost less upfront, require no professional installation, and promise an easy setup that works from your smartphone. But does that convenience provide the protection you actually need?
With nearly 10,000 business burglaries reported in Chicago since 2021 and more than 30 businesses targeted during a single overnight burglary spree, it’s worth asking an important question: Is a self-installed, self-monitored security system enough?
At Alarm Security Inc. (ASI), we’ve protected Chicago-area businesses and homeowners since 1982. With more than 40 years of experience, we’ve seen what works when emergencies happen and what leaves properties vulnerable. Here’s why professionally installed and monitored security systems consistently outperform DIY alternatives.
Shortcomings of DIY Security Systems
DIY security products continue to grow in popularity, but popularity doesn’t guarantee performance. Many self-installed systems work well for basic monitoring, yet they often reveal critical weaknesses during emergencies.
Lack of Monitoring and Slower Response Times
Most DIY security systems depend on you to monitor alerts around the clock. That sounds simple until you’re asleep, in a meeting, traveling, or simply away from your phone.
A burglar alarm or smoke detector may trigger an alert, but if you don’t see the notification immediately, valuable minutes or even hours can pass before anyone responds.
Professional monitoring eliminates that risk. Your alarm connects directly to a staffed central monitoring station operating 24 hours a day. Trained operators verify alarms and contact emergency responders immediately when needed. That faster response can reduce property damage, prevent theft, and even save lives.
Blind Spots and Vulnerable Areas
A security camera only records what it can see. If you install cameras in the wrong locations, criminals can easily avoid them.
Professional technicians evaluate your property before installation. They identify overlooked vulnerabilities such as:
- Poorly lit entrances
- Rear doors
- Loading docks
- Roof access points
- Side gates
- Hidden walkways
This strategic placement creates stronger coverage and eliminates common blind spots.
Compliance, Legal Requirements, and Insurance
Commercial security involves more than installing cameras and alarms. Many businesses must meet local codes and industry regulations.
For example, fire alarm systems must comply with NFPA 72 standards, and many commercial properties require UL-listed fire alarm systems. Chicago, Des Plaines, and surrounding communities also enforce local building codes.
Most consumer-grade DIY systems cannot satisfy these requirements. As a result, businesses may face:
- Failed inspections
- Insurance claim disputes or denials
- Regulatory penalties
- Increased liability exposure
The ASI Difference
Working with ASI means more than purchasing equipment. You’re investing in a professionally designed security solution backed by four decades of local experience.
Complete Security Assessments
Every project begins with a detailed security assessment of your home or business.
Our licensed technicians inspect your property, evaluate entry points, lighting conditions, existing vulnerabilities, and security risks. After completing the assessment, we recommend a customized solution that fits your property instead of forcing you into a one-size-fits-all package.
One Integrated Security Provider
Managing multiple apps, devices, and vendors creates unnecessary complexity.
ASI provides a fully integrated security system that can include:
- Burglar alarm systems with intrusion detection and perimeter protection
- NFPA 72-compliant, UL-listed fire alarm systems
- HD video surveillance with remote viewing and AI-powered analytics
- Access control using key cards, key fobs, and biometric authentication

Bosch-Certified Technical Expertise
As a Bosch Authorized Security Dealer, ASI technicians receive specialized training on Bosch commercial security technology.
Bosch systems deliver exceptional reliability, image quality, detection accuracy, and long-term durability. Unlike many consumer products, Bosch equipment is specifically engineered for continuous professional monitoring and demanding commercial environments.
Fast Local Service
Large national providers often require customers to wait several days for on-site service.
ASI is different.
Our technicians operate from our Des Plaines office and serve the Chicago metropolitan area every day. Because our team lives and works locally, we respond quickly when service is needed, helping restore your security system as fast as possible.
UL-Listed Fire Alarm Services
Many commercial buildings must maintain compliant fire protection systems by law.
ASI designs, installs, inspects, tests, and maintains UL-listed fire alarm systems that meet NFPA 72 requirements and applicable local codes.
Our team helps businesses remain both protected and compliant.
What This Means for Chicago Businesses
Commercial burglary continues to affect retailers, warehouses, dealerships, offices, and industrial facilities throughout Chicago.
Today’s businesses need more than a single security camera. They need a complete security strategy that combines intrusion detection, video surveillance, access control, environmental monitoring, and professional monitoring.
ASI delivers an integrated solution supported by local expertise, experienced technicians, and responsive service that national chains and DIY systems simply cannot match.
What This Means for Homeowners
For homeowners, professional security delivers confidence and peace of mind.
A professionally installed system matches your home’s layout, provides continuous monitoring, and gives you direct access to local experts whenever you need assistance.
Many ASI customers initially tried DIY systems before discovering limitations such as incomplete coverage, false alarms, missed notifications, and limited customer support. They later upgraded to professionally monitored systems that provide stronger protection and dependable local service.
The Real Cost of DIY
DIY systems often appear less expensive at first, but hidden costs can outweigh the initial savings.
Consider these common drawbacks:
- No one responds if you miss an alarm notification.
- Consumer-grade equipment often requires more frequent replacement.
- Some insurance providers offer fewer discounts or may question claims involving inadequate security systems.
- Local service is rarely available when equipment fails.
Professional security provides ongoing support, reliable equipment, and experienced technicians who can quickly resolve problems.
