A commercial security system is a set of connected technologies that protect a business’s people, property, and information.
Infassure has designed and installed these systems since 1985, and we hold Texas Security License #B16058. Our own technicians handle every step, from the site walk to the cabling to the final training session; nobody gets handed off to a subcontractor.
Our offices in Richardson and Houston put us close to Dallas, Fort Worth, and the greater Houston area, and a lot of our work involves multi-site projects for companies with locations across the country.
What We Install
Four core systems make up most of what we install. Each one below links to its own page with more detail on how it works.
Access Control
Card, fob, mobile credential, PIN, or biometric: access control systems handle who gets into which door and when. Every entry gets logged automatically. Lose a badge and we shut it off in seconds. Schedules lock doors on their own and only open them after hours for the people who actually need in.
Video Surveillance
High-definition cameras cover entrances, parking, hallways, and the perimeter, and you can pull up the feed from a phone or a desktop. The newer systems go further: AI analytics flag people, vehicles, and unusual activity as they happen, so you get an alert instead of hours of footage to scroll through later.
Intrusion Detection
Door contacts, glass-break sensors, and motion detectors watch for forced entry and after-hours movement.When something trips, alerts go to the people you choose, the moment it happens. Add silent duress alerts and environmental sensors for water, temperature, or smoke, and it all runs on the same panel.
Structured Cabling and Network Infrastructure
Structured cabling is the wiring behind the cameras, readers, and panels, and it’s what every security system runs on. It’s also the part most likely to get overlooked, even though it decides whether the system still works reliably five years from now. We design and install it as part of the project instead of leaving it to someone else.
Integration
These four systems work best together. A denied badge at the loading dock pulls up the camera automatically. An after-hours alarm sends the video clip along with the alert. One command unlocks doors for evacuation or locks them for shelter-in-place. We build every system this way from day one, and we’ll integrate with cameras, panels, or building systems you already have when it makes sense.
Secure on the Network, Not Just at the Door
Every camera, reader, and panel is a device on your network, so a security system has to be secure itself. Because our network engineers design the system alongside our security technicians, cybersecurity is part of the plan from the start, not something added later.
- Cloud, on-premise, or hybrid. We’ll recommend the setup that fits your IT policies, your number of sites, and how you want to manage the system.
- Separated from everyday traffic. Security devices sit on their own network segment, away from guest Wi-Fi and general office traffic.
- Hardened from day one. Default passwords are replaced and firmware is kept current, so devices don’t become an easy way into your network.
- Built with your IT team. We coordinate with your internal IT staff or managed service provider so the system fits your existing network and policies.
Also From Our Team
Most projects start with access control, video, and intrusion detection, but our team installs the related systems that make a building work as a whole:
- Video intercoms: see and talk to visitors before you unlock the door
- Visitor management: check guests in, issue temporary access, and keep a record of who came and went
- Fire alarm integration: doors on exit routes release automatically when the fire alarm activates
- Audio-visual systems: conference rooms, displays, and paging
- Sound masking: speech privacy for open offices, healthcare, and financial spaces
Security Systems by Industry
A downtown office tower, a hospital wing, and an oil field site all need security, but they don’t need the same system. Each building type has its own traffic patterns, restricted areas, and compliance concerns, so we design around how your building actually runs. Here’s what that typically looks like:
- Commercial and office buildings: multi-tenant permissions, lobby and garage control, tenant self-service
- Healthcare and medical buildings: restricted areas, HIPAA-aware camera placement, duress alerts
- Hotels and hospitality: guest room access, back-of-house control, public area coverage
- Manufacturing and industrial: zone-based access, yard and dock cameras, harsh-environment hardware
- Houses of worship: open during services, secure after, one-button lockdown
- Energy and oil field: remote site surveillance and perimeter detection
- Professional services: client data protection, server rooms, after-hours entry
- Schools and campuses: controlled visitor entry, classroom lockdown, campus-wide camera coverage
- Multi-site retail: consistent standards across every store, after-hours alerts, centralized video access

How We Design and Install a Commercial Security System
The process stays the same whether it’s one office or a dozen buildings across several states. Here’s what that looks like from the first call to the final walkthrough:
- Consultation. We start with your goals, your concerns, and what you already have in place.
- Site assessment. We walk the property, map entry points and blind spots, and check the existing network and cabling.
- System design. You get a plan showing hardware, camera placement, panel locations, cabling runs, and cost, so nothing surprises you at install.
- Installation. Our own technicians do the work, no subcontractors, on a schedule built around your hours.
- Training and handoff. Your team learns the platform before we leave.
- Ongoing support. Maintenance, additions, and upgrades as your business changes.
Security Integrator vs. DIY Kit vs. Monitoring Package
There are three common ways businesses buy security, and each fits a different situation. Here’s how they compare:
| DIY Security Kit | Monitoring Package | Security Integrator | |
|---|---|---|---|
| Best fit | Small shops or single rooms with basic needs | Small businesses that want a packaged system with monitoring | Commercial buildings, multi-tenant properties, and multi-site organizations |
| Installation | You install it yourself, or pay per device | Installed by the provider’s technicians | Designed and installed by a licensed team |
| System design | Off-the-shelf products | Standard packages with set options | Custom design based on a site assessment |
| Scalability | Limited | Moderate | Built to add doors, cameras, and sites over time |
| Multi-site | Managed location by location | Varies by provider | One design standard across every location |
| Integration | Mostly within one brand’s products | Within the provider’s platform | Access control, video, alarms, cabling, and building systems designed to work together |
| Contracts | Usually none | Often a multi-year monitoring agreement | Project-based; you own the equipment |
If you’re protecting a single small storefront, a DIY kit or monitoring package may be all you need. Once you’re managing multiple doors, tenants, restricted areas, or locations, an integrator designs a system around your building instead of fitting your building into a package.

Commercial Security System FAQs
What should I look for in a commercial security system?
Look for a system that fits how your building runs today and can grow with you. The most important features are:
- Access control, video, and alarms managed from one platform
- Remote access from a phone or desktop
- Credentials that are hard to copy, such as smart cards or mobile credentials
- The ability to add doors, cameras, and locations without starting over
- Strong cybersecurity, including network separation and regular firmware updates
- A licensed installer who designs the system and supports it after installation
What does a commercial security system include?
Most setups combine access control, video surveillance, and intrusion detection on one platform, tied together with the network cabling that connects them. Bigger facilities often add emergency integrations, including lockdown, mass notification, and fire alarm tie-ins.
How much does a commercial security system cost?
Cost depends on a few specific factors:
- Number of doors. Each controlled door needs a reader, lock hardware, and wiring, so door count is usually the biggest cost driver for access control.
- Number and type of cameras. Interior, exterior, and specialty cameras such as license plate readers vary in price, and so does the amount of video storage you need.
- Existing cabling. Reusing cabling that’s in good shape can lower costs. Older or damaged cabling usually needs to be replaced for the system to stay reliable.
- Number of buildings or sites. Multi-site projects add design and coordination, but one standard across all locations saves money over time.
- Integration. Tying in fire alarms, intercoms, or building systems adds to the scope.
A small office system might start in the low thousands, and larger facilities scale up with door and camera counts. A site assessment is the only way to get an accurate number, and we’ll give you a clear, itemized price before any work begins.
Can you work with the cameras and panels we already have?
Often, yes. During the site assessment we’ll evaluate what’s there and keep whatever’s in good shape. Older proximity card systems and analog cameras usually aren’t worth keeping; newer IP equipment often is.
Do you install outside of Texas?
Yes. Our offices are in Richardson and Houston, but we regularly handle multi-site and out-of-state projects for companies with locations across the country.
How long does installation take?
A single building usually takes days to a few weeks, depending on door count and cabling. Multi-site rollouts get phased out, and we’ll hand you a schedule along with the design.
How do you handle camera placement in healthcare facilities?
We place cameras to protect entrances, pharmacies, and other restricted areas while avoiding the places where patient privacy matters most. That means keeping cameras out of exam and treatment rooms, angling them away from screens and charts that could show patient information, and limiting who can view recorded video. We also work with your compliance or privacy officer so the design fits your facility’s HIPAA policies.
Should I use a security integrator or a DIY system?
It depends on the size and complexity of your property. DIY kits can work for a small storefront or single office with basic needs. Commercial buildings with multiple doors, tenants, restricted areas, or locations usually need an integrator, who designs the system around the building, installs the cabling and hardware, and makes access control, video, and alarms work together. See the comparison above for a side-by-side breakdown.
Is a cloud-based or on-premise system better for my building?
Both work well, and the right choice depends on your building and your IT requirements. Cloud-based systems are easier to manage remotely and across multiple sites, and updates happen automatically. On-premise systems keep video and data on your own servers, which some organizations prefer for control or policy reasons. Many businesses use a hybrid of the two. We’ll recommend the best fit during your site assessment.
How do I know when it’s time to upgrade an older access control system?
Common signs include:
- You still use older proximity cards, which are easy to copy
- The software is no longer supported or updated
- Replacement parts are hard to find
- You can’t manage the system remotely or use mobile credentials
- It doesn’t connect with your cameras or other building systems
An upgrade doesn’t always mean starting over. During a site assessment, we’ll identify what can stay and what should be replaced.
Can a security system integrate with fire alarms, HVAC, or building management systems?
Yes. Access control can tie into your fire alarm so doors on exit routes unlock automatically during an alarm. Commercial security systems can also connect to building management systems, lighting, and HVAC, so the building responds to events. For example, lights can turn on when an after-hours alarm trips. We plan these connections during design so everything works together from day one.
