“How much does a business security system cost?” is the first question most owners ask, and most answers online are national averages from companies that never set foot in Arizona. The numbers below come from our own invoices: more than 1,700 invoices we billed between January 2024 and October 2026 for installation projects, service calls and monitoring. They are real ranges, not a sales pitch. Your quote depends on your building, which is why we start with a free site assessment.

Security camera installation cost
Camera projects are our most common job, and the spread is wide because “a camera system” can mean four cameras on a small office or forty across a warehouse yard. The $1,800 end is usually a handful of cameras added to an existing recorder, or a small shop with short cable runs. The $6,500 end and above is a new system with a recorder, more cameras, outdoor poles or long runs across a lot. What moves the price most:
- How many cameras, and where. Each camera is hardware, cable, mounting and setup time. Outdoor cameras on walls or poles cost more to place than indoor ones on a drop ceiling.
- Cable paths. Open ceilings and short runs are quick. Hard lids, block walls and runs between buildings take longer; for outbuildings we often use a point-to-point wireless link instead of trenching.
- Height. Warehouses, high parapets and parking lot poles often need a scissor lift, which adds a rental to the job.
- Recording. More cameras, higher resolution and more days of footage mean more recorder storage.
- Equipment. We install NDAA-compliant cameras and recorders only. They are not the cheapest on the shelf, but they are what more landlords, insurers and corporate clients now ask for.

Access control system cost
Access control is priced mostly per door. One or two doors with card or fob readers sits at the low end of the range; a suite of offices, a gate and an elevator sits at the high end. The reader is the visible part, but each door also needs an electrified lock or exit device, a door contact, a request-to-exit sensor and a controller, and older doors and frames sometimes need hardware work before a reader can go on. See access control systems.
Business alarm system cost
Intrusion alarms are the least expensive system to install: a panel, door and motion sensors, a keypad and a cellular communicator, plus panic buttons where staff need them. The typical alarm installation in our data is about $1,650. Most of the long-term cost is monitoring. See business alarm systems.
Alarm and video monitoring cost
Most of our customers pay between $480 and $600 a year for 24/7 alarm monitoring, and the most common rate is $540 a year, about $45 a month. That covers the monitoring center watching the panel around the clock, verifying alarms, calling your contact list and dispatching police or fire. Monitoring access control or fire alarm panels is billed alongside it. See 24/7 monitoring.
Service and repair cost
A single service visit, such as replacing a failed camera, fixing a door that will not lock, or getting a recorder back online, typically comes to about $200, and most land between $185 and $385 before any parts. Many problems are diagnosed remotely first, so the technician arrives with the right part. We also service systems another company installed. See maintenance and repair.
How to keep your security system cost down
- Reuse what works. Existing cable, recorders and door hardware can often stay. A site assessment tells you what is worth keeping.
- Cover the right places first. Four to eight well-placed cameras cover most small shops and offices: entrances, registers, back door and parking.
- Plan cabling before the walls close. On new construction and remodels, roughing in low-voltage cabling early is far cheaper than fishing cable later.
- Combine systems. Installing cameras, access control and an alarm in one project shares the cabling, the trip and the setup.

Why such wide ranges?
Because buildings differ. Camera count, door count, ceiling height, cable distance and how much existing equipment can be reused change the price more than anything else.
Is the site assessment free?
Yes. We walk the site, look at what you have, and give you a written quote.
