Access Control Systems
in Broward County, FLFast, Licensed & HOA-Ready

POTS stands for Plain Old Telephone Service — the traditional copper wire telephone network that most HOA and apartment telephone entry systems were designed to use. The problem: AT&T, Verizon, and other major carriers have been systematically disconnecting POTS copper infrastructure across South Florida since 2022 under FCC Order 19-72, which allows carriers to retire legacy copper lines in favor of fiber and wireless networks. A gated community in Broward County that has relied on a DoorKing 1802 or 1812 connected via POTS may suddenly lose telephone entry capability — not because the equipment failed, but because the phone line was disconnected by the carrier with as little as 180 days notice. The replacement solution is a cellular telephone entry system like the DoorKing 1830, which communicates via 4G LTE cellular instead of a copper line — eliminating the POTS dependency entirely and adding cloud management capabilities that legacy systems cannot provide.

The DoorKing 1830 is DoorKing's current-generation cellular and cloud-managed telephone entry system. Unlike the 1802 and 1812 — which require a POTS copper telephone line and are programmed via a physical handset or DKS software connected directly to the unit — the DoorKing 1830 operates via 4G LTE cellular, requires no phone line, and is fully managed through the DoorKing Connect cloud portal. For HOA property managers in Broward County, the difference is transformational: adding a new resident, changing a code, or pulling an entry log can be done from any browser in under two minutes — rather than waiting for a technician to drive to the property and physically connect to the unit. The 1830 also supports virtual keys, smartphone entry, and integrated visitor PIN management that the legacy 1802/1812 systems cannot offer.

Yes — this is the primary operational advantage of cloud-managed access control systems over legacy installations. With a DoorKing Connect, ButterflyMX, or Brivo cloud portal, the HOA property manager or on-site manager logs into a web browser from any computer, tablet, or smartphone and has full administrative access to the resident directory in real time. Adding a new resident takes approximately 90 seconds: enter the name, unit number, phone number, and any access credentials (virtual key, PIN code, RFID fob number), then save. The change is pushed to the gate system instantly over the cellular or internet connection. Removing a resident who has moved out — and revoking all their access credentials simultaneously — is a single button click. No technician visit, no programming cable, no appointment required. For communities with 100+ units and frequent turnover, this capability alone typically justifies the upgrade cost within the first year of operation.

A UHF (Ultra High Frequency, 860–960 MHz) RFID windshield tag is a passive RFID transponder that adheres to the vehicle's interior windshield. A UHF reader mounted at the gate entrance reads the tag from a distance of 20–30 feet as the vehicle approaches at normal driving speed — the gate opens before the vehicle reaches the gate, creating truly frictionless vehicle entry with no stopping, no window rolling down, and no button pressing. Standard 125kHz proximity key fobs require the driver to either slow to a near-stop or hold the fob out the window for the reader to trigger within 2–4 inches. For high-volume HOA communities, this difference eliminates the queue of vehicles stacking up at the entry lane during peak commute times. UHF windshield tags are programmed with a unique identifier, can be instantly revoked from the cloud management portal, and are typically issued per-vehicle rather than per-person for precise vehicle-level access logging.

These are the two fundamental access control power failure modes, and choosing the wrong one for a given door can create serious safety or security problems during South Florida's hurricane-related power outages. Fail-safe (also called "normally open" or NO): the lock requires electrical power to remain locked. When power fails, the door unlocks automatically. This is required by NFPA 101 (Life Safety Code) and Florida fire codes for all egress doors — exterior exits that people must be able to pass through during a fire or emergency evacuation, regardless of power status. If a fail-safe maglock is on an exterior exit and power fails during a hurricane, the door opens. This is the correct and legally required behavior for life safety. Fail-secure (also called "normally closed" or NC): the lock retains its locked position when power fails. This is appropriate for interior security doors, server rooms, and other doors where security must be maintained even during a power outage. It is NOT appropriate for egress doors. The correct solution for South Florida communities requiring security during extended outages is battery backup UPS systems on fail-secure locks — maintaining locked status for 4–24 hours depending on battery capacity — rather than misapplying fail-secure configuration to egress doors in violation of fire code.

South Florida's lightning season (June–September) produces more lightning strikes per square mile than almost any region in the United States — and Broward County consistently ranks among the highest in the state. A direct or nearby lightning strike induces a transient voltage surge on any connected conductor: the telephone line, the power supply, and any signal wires connected to the access control board. A typical access control board replacement costs $800–$2,500 installed. A proper UL 1449 3rd Edition Surge Protective Device (SPD) costs $30–$80 installed per line. Without protection, a single lightning event can simultaneously destroy the telephone entry board, the gate operator control board, and any connected cameras or intercoms — a $5,000–$15,000 repair event. Proper protection includes: a UL-listed SPD on the power supply input (AC side), a telephone line surge protector on any POTS or DSL input (for legacy systems), and signal line protectors on any long cable runs between the gate post and the control panel. For cellular systems like the DoorKing 1830, the POTS surge path is eliminated, but power and signal surge protection remains essential. We install SPD protection on every access control system we touch as a non-negotiable standard.

Standard consumer-grade LCD panels — including those found in many entry-level telephone entry and video intercom systems — are rated for operating temperatures up to approximately 50°C (122°F) internal panel temperature. On a south-facing wall in Broward County with direct afternoon sun exposure, the surface temperature of a metal enclosure can exceed 70–80°C (158–176°F), driving internal panel temperatures well above the rated maximum. The result: LCD backlight failure, color wash-out, screen blackout, or permanent polarizer damage — leaving the keypad display unreadable in the very conditions when residents most need to use it. The solution is industrial-grade access control panels with: (1) 1,000–1,500 nit high-brightness LCD panels that maintain readability in direct sunlight (standard consumer LCD panels are 200–400 nit — completely washed out in South Florida sun). (2) Wide-temperature operation ratings of -20°C to +70°C internal. (3) Anti-UV polycarbonate lens covers that block UV-induced polarizer degradation. (4) Vented or thermally managed enclosures that dissipate heat buildup. We specify industrial-grade or properly rated panels on all South Florida access control installations — particularly for units mounted on east or west walls receiving direct morning or afternoon sun exposure.

ButterflyMX is a cloud-based video intercom system purpose-built for multifamily and HOA communities. Instead of a traditional hardwired intercom panel that connects to individual unit phones, ButterflyMX uses a single outdoor video panel (with camera, touchscreen, and intercom) connected to the internet via Wi-Fi or cellular. When a visitor presses a resident's unit button, the call is delivered as a smartphone video call to the resident's iOS or Android device — from anywhere in the world. The resident can see the visitor, speak with them, and unlock the door or gate with a button tap. For HOA property managers, ButterflyMX's cloud portal provides: a full entry log with timestamped photos of every person who entered, virtual keys that can be issued for one-time or scheduled access (deliveries, contractors, guests), resident self-onboarding without manager involvement, and system-wide updates pushed automatically. ButterflyMX integrates directly with major property management software platforms and does not require a POTS telephone line.
