Platform focus
Elwin Security installs, configures, repairs, and supports Verkada access control, video intercoms, and cameras for commercial and multifamily properties in Santa Clara and the San Francisco Bay Area.
Use case
The controller family, the lock at each door, the cable runs, and the switch ports behind them set the scope of a Verkada job.
Verkada's AC12 datasheet describes a one-door controller powered by a single PoE cable, which it says minimizes the need for long low-voltage cable runs between doors and IDF (wiring) closets. The same datasheet lists one lock, two readers, and one PoE+ peripheral such as a Verkada camera powered from that unit.
Verkada's intercom guide says an intercom can be configured as a one-door controller by wiring it to an auxiliary power controller and a lock. The guide adds that no separate door license is needed for that door; it is included with the intercom license.
Verkada's camera network page says cameras are powered through PoE, and its power page says to use PoE injectors between the camera and the switch when the switch has none. The CD53 datasheet lists 16.8 W on 802.3at PoE+ with IR on and 8.5 W on 802.3af PoE with IR off.
Service focus
The field conditions decide whether each device powers up, reaches Command, and releases the door.
The AC12 datasheet lists wet relay outputs at 12 VDC operation 700 mA max and 24 VDC operation 350 mA max. Verkada's wiring guide says in a dry setup the access controller does not provide power to the locking hardware ("typically used with external power supplies").
Verkada's wiring guide states that an external power supply (dry setup) must be used when wiring a crash bar, and recommends one for a maglock without requiring it. The AC12 datasheet adds that installation and operation of the electronic access control system shall not prevent the functionality of the emergency exit functions. Your fire marshal or AHJ determines compliance.
Verkada's access control network page says access controllers use DHCP on UDP ports 67 and 68 to obtain IP addresses and network configurations, and communicate using UDP port 53. The same page states that Verkada devices are incompatible with LANs that require proxy servers or SSL/TLS inspection unless a bypass is implemented for all Verkada devices.
The TD63 datasheet lists 802.3af PoE input, with 802.3at PoE+ for its extended temperature range, plus IP66 and IK08 ratings.
Site walk
The walk confirms what each device needs to power up and connect, and what the property team will manage afterward.
Lock voltage and current against the controller's wet relay limit, whether a crash bar or maglock goes on an external supply, request-to-exit and door-position contacts (dry contacts, optional but recommended in Verkada's guide), and fail-safe or fail-secure behavior.
Reader runs against Verkada's wiring table, which lists Reader Option 1 at 250 ft (76 m), Reader Option 2 at 300 ft (91 m), and Reader Option 3 at 500 ft (152.4 m).
Whether the property already has a Verkada Command organization, who holds Org Admin and Access Site Admin roles, which license terms are in place, and how users, schedules, credentials, and intercom call routing will be managed after handoff.
System layers
Verkada's documents list power, cable, and network requirements for the controllers, readers, intercoms, and cameras.
AC12: one door, 15 W max on PoE, 28 W max on PoE+, 60 W max on PoE++ with a PoE passthrough camera, or 12 VDC with 2.5 A minimum current (AC12 datasheet).
Verkada's reader guide says third-party OSDP readers connect to any Verkada ACU at channel address 0 and 38400 baud, Wiegand-only readers use the ACU's Wiegand ports, and OSDP to third-party readers is not encrypted.
The TD63 datasheet lists a 12-button keypad, a 5 MP camera, 512 GB onboard storage, three dry inputs, two dry relays rated 30 VDC at 1 A resistive, one RS-485 port, and recessed mounting on a double-gang box. Verkada's intercom wiring guide says intercoms require a PoE or PoE+ enabled switch port.
Verkada's camera network page lists TCP/UDP 443 and UDP 123, and says a blinking blue status LED or an alternating blue and amber status LED indicates the camera is not communicating with Command. Verkada's bandwidth page says cameras record video locally, limiting consumption bandwidth, and operate at a steady upload state of 20-50 Kbps.
Process
Elwin plans the field work, the network rules, and the administrator setup before devices are mounted.
Record each lock's voltage and current, choose wet or dry relay wiring per Verkada's limits, map reader and lock runs against the recommended-wire lengths, and set panel locations with AC power or the right PoE class.
Result: Each door has a power path inside Verkada's published limits.
Confirm the network rules on Verkada's network settings pages are met, arrange a bypass if the LAN uses a proxy or TLS inspection, confirm the Command organization exists, and add the devices to it before installation begins, as Verkada's deployment guide recommends.
Result: The network and the organization are ready before devices are mounted.
Mount controllers, readers, intercoms, and cameras, terminate and label the wiring, configure doors, schedules, credentials, and call routing in Command, test each opening, and hand off administrator access.
Result: Administrator access is handed off to the property team with each opening tested.
What matters
The limits that decide a Verkada job come from Verkada's datasheets, product pages, help center, and pricing page.
Lock power: Verkada's wiring guide says you must use an external power supply (dry set up) when you wire a crash bar.
Licensing: Verkada's licensing article says valid licenses are required for all Verkada products to access Command, licenses co-term to a single expiration date, and access is lost 30 days after an unrenewed expiration.
A reader beside the entry doors, a camera at the building corner, and a gated side path.
A technician fastens a small wall-mounted device on an exterior stucco wall; the device shows a red indicator light.
Yes. Elwin Security installs, configures, repairs, and supports Verkada access control, video intercoms, and cameras for commercial and multifamily properties in Santa Clara and the San Francisco Bay Area, including the door hardware, low-voltage wiring, and network preparation each device needs.
Site walk
Tell Elwin what is not working, what systems are already on site, and which access points matter most. The next step is a scope grounded in the building, not a generic product list.
