TL;DR — In SDS’s experience, roughly 80% of commercial access control installations are hardwired. Wired access control is the more reliable, more scalable choice for new construction and high-security multi-door jobs. Wireless access control is faster and less invasive for retrofits where running new cable is not practical. Security Data Supply carries hardware for both, so the sourcing decision comes down to the job, not the distributor.
That’s the short answer. The choice between wired and wireless access control comes down to a handful of factors, building type, door count, and whether the walls are already open, and this post walks through how to weigh them before you spec the job.
Wired vs. Wireless Access Control: The Core Tradeoff
Every commercial access control job eventually comes down to the same question: run wire, or do not. Wired access control connects each reader and controller directly back to a central panel or power source. Wireless access control uses battery-powered locks and readers that communicate over a wireless protocol back to a hub, cutting out most of the cable run.
Neither approach is universally better. The right answer depends on the building, the door count, and what it would take to get cable where it needs to go.
When Wired Access Control Is the Right Call
Wired access control is the standard for new construction, high-security applications, and any job where the walls are already open. It is also the default for most commercial work: in SDS’s experience, roughly 80% of commercial access control installations are hardwired. Running cable during construction costs far less than retrofitting it later, and a wired system gives you the most reliable power and communication path with the fewest points of failure.
For multi-door commercial buildings with a high door count, wired systems also scale more predictably. Adding doors to a wired system is a matter of running more cable and adding controller capacity, not managing battery life and wireless range across a growing mesh of devices.
When Wireless Access Control Makes More Sense
Wireless access control earns its place in retrofits, historic buildings, and any job where opening walls to run cable is not practical or not in the budget. A wireless lock can go on a door in a fraction of the time a wired install takes, with far less disruption to a building that is already occupied.
The tradeoff is maintenance. Wireless locks run on batteries that need monitoring and replacement, and wireless range and interference can vary by building construction. For a single door or a small addition to an existing system, that tradeoff is usually worth it. For a ground-up 40-door install, it usually is not.
What This Means for Multi-Door Commercial Jobs
Most commercial jobs are not purely wired or purely wireless. A common pattern is wired access control on primary entrances and high-traffic doors, with wireless filling in secondary doors, interior offices, or areas where running cable would mean tearing into a finished space.
SDS carries access control hardware from a broad brand lineup, including Alarm.com, 3xLOGIC, CDVI, HID, Keri Systems, Keyscan, LiftMaster, Linear, Napco, PDK (ProdataKey), and ZKTeco, along with mag locks and door controllers, to support both approaches. Bring the job specifics to the counter, door count, new construction or retrofit, budget, and the team can help you land on the right mix before you order.
Frequently Asked Questions
What percentage of commercial access control installs are wired?
In Security Data Supply’s experience, roughly 80% of commercial access control installations are hardwired. Wired systems remain the default for new construction and high-security, multi-door jobs, while wireless is most common in retrofits where running new cable is impractical.
Is wireless access control as secure as wired for a commercial building?
Wireless access control can meet commercial security requirements, but wired systems generally offer the most reliable and lowest-failure-point option for high-security applications. The right choice depends on the specific security requirements of the job.
Can I mix wired and wireless access control in the same building?
Yes. Many commercial installs use wired access control on primary entrances and wireless on secondary doors or areas where running cable is impractical.
Does wireless access control need a different power source than wired?
Yes. Wireless access control hardware typically runs on batteries that require ongoing monitoring and replacement, while wired systems draw power through the cable run from a central source.
Which is better for a retrofit: wired or wireless access control?
Wireless access control is generally the better fit for retrofits, since it avoids the cost and disruption of opening walls to run new cable.
Does SDS carry hardware for both wired and wireless access control installs?
Yes. Security Data Supply carries access control hardware to support both wired and wireless installs, including Alarm.com, 3xLOGIC, CDVI, HID, Keri Systems, Keyscan, LiftMaster, Linear, Napco, PDK (ProdataKey), and ZKTeco, along with mag locks and door controllers.

Methodology
This post reflects general access control industry practice on wired and wireless system tradeoffs, combined with Security Data Supply’s confirmed access control brand list (Alarm.com, 3xLOGIC, CDVI, HID, Keri Systems, Keyscan, LiftMaster, Linear, Napco, PDK (ProdataKey), and ZKTeco) and mag locks and door controllers. The estimate that roughly 80% of commercial access control installations are hardwired is Security Data Supply’s own field estimate, not a published third-party statistic. It is written to apply across SDS’s franchise network rather than to any single franchise.
