Wired vs wireless access control.
A criterion-by-criterion read from an integrator that installs both. This is mostly a retrofit-economics question, not a security one. Most large deployments mix the two, door by door.
- NDAA-compliant
- Platform-agnostic
- 1,000+ deployments over 15 years
Go wired for new construction, high-security or high-traffic doors, and any door where conduit and power are already available. Go wireless for retrofits in finished spaces where running conduit is disruptive or cost-prohibitive, low-to-medium-traffic interior doors, and facilities adding access control to 30+ doors without a major construction project. Many large deployments mix both: wired at perimeter and high-security doors, wireless on interior office and storage doors.
§01 At a glance
What separates them.
Find the criterion that matters most for your doors and building type, then read the row. This is architecture against architecture, not a vendor pitch. Wired platforms: Genetec Synergis, Lenel OnGuard, Brivo, Kisi (all support wired doors natively). Wireless platforms: Salto XS4/Space, Allegion Schlage NDE/LE, ASSA ABLOY Aperio, HID EDGE.
| Criterion | Wired access control | Wireless access control |
|---|---|---|
| Cabling and conduit | Requires a CAT5e or CAT6 run and a power circuit to each door. In new construction, conduit is cheap. In finished occupied spaces, cutting walls, pulling conduit, and patching costs can dwarf the hardware cost. | No data cabling to the door. A wireless controller (gateway) sits in an IDF closet and communicates to the lock via RF (proprietary 868 MHz or 2.4 GHz mesh). No conduit to individual doors; the only wiring is the gateway to the network. |
| Power source | Continuous power via PoE (for PoE controllers) or dedicated 12/24VDC from a power supply. Supports electric strikes, mag-locks, and electrified hardware requiring sustained current. No battery changes. | Battery-powered at the door. Typical battery life is 1 to 3 years depending on traffic volume, lock type, and temperature. High-traffic doors drain batteries faster. Battery replacement is a recurring maintenance task. |
| Lock hardware options | Full range: electric strikes, magnetic locks, electrified mortise locks, electrified panic hardware, and electrified cylindrical locks. Supports fail-secure and fail-safe hardware for life-safety compliance. | Wireless cylinders, wireless escutcheons, wireless padlocks, and wireless mortise cases. Most wireless platforms do not support mag-locks or electric strikes. For perimeter doors requiring mag-locks or panic hardware, wired is the only path. |
| Latency and response time | Local controller decision: credential is evaluated at the controller in the IDF, door releases in under 100ms. No RF hop, no battery wake cycle. Consistent and fast. | Wireless lock wakes from low-power state, communicates to the gateway via RF, and releases the latch. Typical credential-to-release latency is 300ms to 800ms for most wireless platforms. Perceptible on busy doors; acceptable on low-traffic interior doors. |
| Retrofit difficulty | Difficult in finished occupied spaces. Cutting drywall, pulling conduit, patching, painting. Historic buildings and multi-tenant environments often have restricted plenum or ceiling access. Labor costs can run 2-3x the hardware cost on a complex retrofit. | Minimal construction impact. Wireless lock replaces the existing mechanical lock cylinder or mortise case; gateway sits in the nearest IDF closet. Most wireless retrofits are done with a screwdriver and a drill, not a conduit crew. |
| Scalability | Each door requires its own PoE run and controller allocation. Expanding requires conduit runs. Scales well in planned buildouts where infrastructure is designed upfront. | Adding doors means adding a wireless lock and provisioning it in the platform. Gateway capacity limits the number of doors per gateway (typically 64 to 128 nodes per gateway depending on platform). Scaling large wireless deployments requires adding gateways, not pulling conduit. |
| Cybersecurity posture | Communication runs over the wired LAN/VLAN. No RF attack surface at the door. Standard IT security controls (802.1X, VLAN segmentation, encrypted communication) apply. | RF communication between lock and gateway introduces a wireless attack surface. Enterprise wireless platforms (Salto, Allegion, ASSA ABLOY Aperio) use AES-128 or AES-256 encrypted RF. Proprietary frequency hopping and key rolling mitigate replay attacks. Audited and deployed at high-security facilities. |
| Maintenance overhead | No battery changes. Door hardware is fixed infrastructure; maintenance is firmware updates (pushed via network) and periodic door hardware inspection. Electromechanical components (strikes, hinges, closers) are the usual failure points. | Battery replacement is the primary ongoing maintenance task. Battery health monitoring is standard on enterprise wireless platforms (Salto XS4, Allegion NDE/LE); alerts push to the access control dashboard when voltage drops. High-traffic doors may require annual battery changes; low-traffic doors may run 3+ years. |
§02 Where Wired access control wins
Choose wired access control when these matter most.
Perimeter and high-security doors
Main entrances, loading docks, server rooms, and any door requiring mag-locks, electric strikes, or electrified panic hardware. Wired supports the full range of electrified hardware. Wireless platforms do not support mag-locks or continuous-duty electric strikes; for those doors, wired is the only path.
High-traffic doors
Badge readers processing hundreds of credentials per hour benefit from the sub-100ms response time and continuous power of a wired controller. Wireless latency and battery drain under high traffic make wired the right choice above 50 to 100 transactions per day.
New construction with continuous power
When you are pulling conduit for other systems anyway, wired adds a modest increment, and rough-in conduit during construction is the cheapest it will ever be. Wired controllers also drive request-to-exit sensors, door position switches, and relay outputs with the continuous power that video intercom and door-held-open alarms need.
Lowest maintenance and cybersecurity-sensitive sites
No battery changes over the life of the system; across 100 doors, annual battery-replacement labor adds up, and wired avoids it entirely. Defense contractors, financial institutions, and data centers that run RF security audits sometimes specify wired-only to eliminate the wireless attack surface, since credentials travel a supervised wired network with no RF to sniff or replay.
§02 Where Wireless access control wins
Choose wireless access control when these matter most.
Retrofits in finished occupied spaces
The most common wireless case: a corporate tenant wants access control on 40 interior doors. Cutting drywall and pulling conduit to 40 doors in an occupied space is months of disruption and significant spend. Wireless locks install with a screwdriver in a day, the gateway goes in the IDF closet, and the construction impact is zero.
Interior office and storage doors
Low-to-medium-traffic interior doors (private offices, conference rooms, server closets, storage rooms) are the sweet spot for wireless. Traffic is low, latency tolerance is higher, and a standard lever handle with no visible wiring suits finished office environments.
Historic buildings and rapid rollouts
In historic buildings, landmarked facades, and spaces where opening walls would violate codes or lease restrictions, wireless cylinders and escutcheons replace the mechanical hardware with the reader face the only visible change. Wireless also turns a 75-door campus rollout into a provisioning exercise; Salto and Allegion NDE/LE installs run on a week-per-building schedule rather than a month-per-building one.
Tenant environments and mixed deployments
For multi-tenant buildings and co-working spaces where tenants control suite doors without conduit access, wireless lets landlords add per-tenant access without rewiring. The practical large-deployment answer mixes both: wired at perimeter and high-security, wireless interior. Salto, Allegion Schlage, and ASSA ABLOY Aperio integrate into the same head end via their gateway, so one Genetec Synergis or Lenel OnGuard deployment manages both in one credential database.
§03 How each architecture works
Wired and wireless access control, defined.
Wired access control runs a dedicated CAT5e or CAT6 cable from an IDF closet to a field controller at each door. The controller connects to a panel or server, evaluates credentials, and drives the door hardware (electric strike, mag-lock, or electrified lock). Power comes via PoE or a dedicated supply; readers communicate over Wiegand or OSDP. Every major platform (Genetec Synergis, Lenel OnGuard, Software House C-CURE, Brivo, Kisi) supports wired doors. It is the default for commercial access control.
Wireless access control puts a battery-powered lock at the door that communicates to a gateway in the IDF closet via proprietary RF; the gateway connects to the server over the wired LAN. The door has no data cable and no power circuit, so the only change is replacing the mechanical lock with a wireless electromechanical one. The major platforms are Salto XS4 and Salto Space, Allegion Schlage NDE and LE series, ASSA ABLOY Aperio, and HID EDGE. Each uses a different RF stack, but the operating model is the same.
- → Most wireless platforms integrate as a subsystem into a wired head end. Salto integrates with Genetec, Lenel, and most major platforms via Salto Bridge; Aperio integrates similarly. You manage both wired and wireless doors from one credential database.
- → OSDP (Open Supervised Device Protocol) is the current wiring standard, replacing Wiegand with encrypted, supervised reader-to-controller communication. Spec OSDP-capable readers on any new wired installation.
- → Battery life is well-documented: Salto XS4 One Bluetooth locks are rated at approximately 60,000 operations per battery set, Allegion NDE locks at approximately 100,000. Traffic-heavy doors exhaust these faster; budget for annual battery checks above 30 operations per day.
§04 The real cost picture
What wired and wireless access control actually cost.
Door hardware is the dominant line on both sides, and a commercial-grade wired door (reader, controller, electric strike, power supply) is roughly comparable in hardware cost to a commercial-grade wireless lock with reader. The divergence is install labor. Wired in new construction: conduit is budgeted, labor is incremental. Wired in a finished occupied space: add conduit pull, drywall, patch, and paint. That delta is why wireless wins the retrofit math even though hardware costs are similar.
Battery replacement is the wireless recurring cost that is easy to underestimate. In a 60-door deployment where 30 high-traffic doors need annual changes and 30 low-traffic doors run every two years, that is a real service cadence with labor attached. Enterprise platforms push battery alerts to the dashboard, batching replacements into scheduled visits rather than emergency calls. Over five years, battery labor in a large wireless deployment is a meaningful line to model explicitly.
- → Wired cost drivers: conduit and cabling labor (widest-swinging variable), field controller, power supply, and reader. In new construction, wired is typically cheaper per door all-in than wireless.
- → Wireless cost drivers: lock hardware (typically higher than a basic wired reader-plus-controller set), gateway hardware (one gateway serves 64-128 doors), and recurring battery labor.
- → Retrofit break-even: in the quotes Tec-Tel benchmarks, wireless becomes cheaper when the conduit pull plus patch labor exceeds roughly the wireless hardware premium, a threshold hit quickly in finished office environments.
- → Confirm gateway coverage before specifying wireless at scale (each gateway handles 64-128 nodes), and spec platforms that push battery alerts to the dashboard. One platform, one credential database covers both wired and wireless doors via the gateway.
Questions buyers ask us
FAQ
- Can wireless access control be as secure as wired?
- Yes for most commercial applications. Enterprise platforms (Salto XS4, Allegion NDE/LE, ASSA ABLOY Aperio) use AES-128 or AES-256 encrypted RF with proprietary frequency hopping and credential key rolling, deployed at hospitals, financial institutions, and government facilities. The residual risk relative to wired is the RF attack surface at the door. For facilities under strict cybersecurity frameworks (CMMC, FISMA) or running RF audits, wired is the conservative choice. For the vast majority of deployments, enterprise wireless passes security review.
- Do I need to replace all my locks to add wireless access control?
- Only the locks on doors you want to control. Wireless retrofits replace the mechanical cylinder or mortise case with a wireless electromechanical version from the same line (Schlage, Allegion, ASSA ABLOY); the door frame, closer, and trim typically stay. Locks outside the access scope stay as-is. A phased rollout is common: control the most critical doors first, add more later without additional construction.
- How long do wireless lock batteries actually last?
- A function of traffic, temperature, and lock type; manufacturer ratings assume moderate traffic. Salto XS4 One Bluetooth: approximately 60,000 operations per battery set (typically 2 AA). Allegion Schlage NDE: approximately 100,000 operations. At 50 daily transactions, that is roughly 3 years for the NDE and 2 for the Salto. At 200 daily transactions, plan for annual replacement. Enterprise platforms push low-battery alerts with enough lead time to batch replacements into scheduled visits.
- Can I mix wired and wireless doors in the same access control system?
- Yes. Most enterprise platforms support both. Genetec Synergis integrates Salto XS4 via Salto Bridge and Aperio via the Aperio Gateway; Lenel OnGuard integrates most major wireless platforms; Brivo and Avigilon Alta support Salto on select configurations. The credential database, schedules, and audit logs are unified, and the administrator sees wired and wireless doors in one interface. The gateway is the only additional line item for wireless doors.
- Are wireless locks suitable for fire-rated and life-safety doors?
- Wireless electromechanical locks can go on fire-rated assemblies provided the lock hardware carries the appropriate listing (UL 10C positive pressure, etc.). Fire rating depends on hardware certification, not the communication method. But if the door has electrified panic hardware with continuous power requirements (as many code-required egress doors do), that hardware needs wired power regardless. Review life-safety doors with the AHJ during design.
- How does the consultation approach wired vs wireless for my facility?
- On the call (855-577-0400 or the booking link) we go through your floor plan, door count, existing mechanical lock hardware, IDF closet locations, and which doors are in finished vs under-construction spaces. You come away with a door-by-door recommendation (wired, wireless, or excluded), a gateway placement plan for the wireless doors, and a 5-year cost bracket for each path. On retrofits we add a conduit-pull vs wireless cost comparison so the math is explicit before you commit.
