LiftMaster CAPXS Manual Overview

The LiftMaster CAPXS Smart Video Intercom S (Model CAPXS) is, in LiftMaster's words, a cloud based access control solution that includes an integrated video camera enabling advanced video features. It controls one access point (a door or a gate) through a touchscreen display, microphone, speaker, camera, a primary relay, an auxiliary relay, and Wiegand, request-to-exit, supervised, and postal lock inputs. It connects to the internet by Ethernet or Wi-Fi and is managed through a myQ Community account.

LiftMaster's installation manual is organized in four parts after the introduction: (1) myQ Community account setup, (2) power, (3) network and mounting, and (4) access control. This page follows the same order. The manual covers the CAPXS only; it contains no troubleshooting chart or diagnostic code table, so this page has none either. See Reset Button for the manual's recovery procedure.

CAPXS Connections Overview

The CAPXS has a combination of access control inputs and outputs that work together to control one access point (LiftMaster, page 5).

LiftMaster's overview illustration (page 4) labels the display (touchscreen), microphone, speaker, camera window, terminals, power, reset button, Ethernet connection, and postal lock switch. The terminal block is labeled POSTAL LOCK, WIEGAND (BLACK GND, GREEN DATA0, WHITE DATA1), REX / GND / SUP, PRI. RLY. (N.O., COM, N.C.), and AUX. RLY. (N.O., COM, N.C.). Per the manual, only the 26-bit Wiegand protocol is compatible in UL installations. See pages 15 and 16 of the manual for the wiring diagrams, and Door Access and Gate Access below.

What Is in the CAPXS Carton

LiftMaster's carton inventory (page 6) lists these items. The manual notes that the installation manual is provided but not shown.

• Power supply

CAPXS Wire Specifications and Internet Requirements

Wire Specifications

LiftMaster says to use this chart to pull wires in preparation for installation, and to check the national and local building codes BEFORE installation (page 8).

Swipe sideways to see all columns.

LiftMaster's notes: main power supply and control wiring MUST be run in separate conduits. Conduits must be UL approved for low and high voltage. Refer to the NEC for additional wiring requirements. Category 5e cabling is the minimum performance category recommended. Wiring shall be in accordance with the National Electrical Code (ANSI/NFPA 70), local codes, and authorities having jurisdiction.

Always provide power from a dedicated source. Plug the provided transformer into an outlet wired to its own 10 Amp minimum circuit breaker. This prevents two problems: other equipment cannot introduce spikes, noise, surges, or dips into the power circuit that will affect the system, and the system's operation will not be affected if other equipment develops a short circuit across the power line.

*CAT 5/6 network cable notes: for outdoor distances exceeding 140 feet (42.7 m), a UL497 compliant primary surge protector MUST be installed at the CAPXS. Distances exceeding 328 feet (100 m) may be accommodated with additional hardware (available through third-party sources).

Internet Requirements

When selecting a router, use the following information to ensure compatibility (page 9). The CAPXS can be connected to a router through a wired connection or Wi-Fi. LiftMaster recommends a minimum upload/download speed of 5 Mbps for each CAPXS supporting video camera feeds. This upload speed should be met when considering the use of other devices on the network, like cameras and computers.

• Wi-Fi security compatibility: WPA3 Personal and WPA2 Personal (AES).
• Wi-Fi protocols: 802.11b, 802.11g, and 802.11n.
• Wi-Fi extenders: DO NOT use Wi-Fi extender devices. They may introduce latency in the connection, leading to choppy or lost video transmission.
• Signal strength: if using a Wi-Fi signal strength tool or app, a continuous Wi-Fi signal strength of at least -65 dBm (numbers closer to zero are stronger) at the CAPXS must be guaranteed to ensure an acceptable connection to the local network. When checking signal strength in CAPXS admin mode, LiftMaster recommends at least two bars, as shown on the CAPXS screen.
• Hidden networks: hidden network SSIDs are not supported. The network must be selectable from the CAPXS display.
• Secondary authentication: Wi-Fi networks requiring secondary authentication are not supported (for example, hotel and airport Wi-Fi).

myQ Community Account Setup

LiftMaster's step 1 (page 10) sets up the myQ Community account and services the CAPXS needs. If you have an existing myQ account, your myQ Community account will have the same password (go to account.myQ.com and log in).

Set Up a myQ Community Account

If you do not have a myQ Community account, LiftMaster gives two methods.

For support, LiftMaster lists 877.247.6764 or support.partner.liftmaster.com/s/community-access-support. VoIP service is required for the calling function: LiftMaster partners exclusively with Phone.com for integrated voice and video calling, and other VoIP providers are not compatible with the CAPXS.

Sign Up for myQ Community Services

Service subscriptions are required for the CAPXS to fully function. To sign up for services:

LiftMaster CAPXS Installation

LiftMaster's installation steps are: Step 1, install the mounting bracket; Step 2, connect power; Step 3, connect internet; Step 4, set up the CAPXS; Step 5, mount the CAPXS; and then wire the door or gate access.

Install the Mounting Bracket (Step 1)

• ADA compliance: when mounting the CAPXS at a pedestrian entrance, to meet ADA compliance, mount the top of the CAPXS screen no higher than 54 inches from the ground.
• Sealing: make sure the CAPXS is properly sealed to prevent damage from moisture. For rough surfaces such as brick, additional sealing will be needed.

LiftMaster's illustrations show a surface mount and a gang box mount.

Connect Power (Step 2)

The outlet for the CAPXS MUST be an external dedicated 120 Vac outlet, wired back to its own 10 Amp minimum circuit breaker. Maximum wire run distances for the power wiring:

Swipe sideways to see all columns.

• If the power supply is installed outdoors, the power supply must have its own approved NEMA 4 rated weatherproof electrical enclosure. Use conduit from the power supply enclosure to the controller enclosure.
• When the power supply (low voltage) wiring leaves the enclosure, the wire must be rated for wet and damp locations.
• High voltage wiring must be run in a separate conduit from low voltage wiring.

Connect Internet (Step 3)

The CAPXS can connect to the internet with a wired connection or with Wi-Fi (wireless); see Internet Requirements. If you are not in Admin Mode, press the 3 dots in the upper right corner of the CAPXS display and enter the Admin Code, press the Network tab on the display, and press the "Change Network Settings" button. Follow the instructions for your application.

Note: the default Admin Code can be found in your myQ Business account. When you add a CAPXS device to a facility, you will be prompted to create a new Admin Code.

Additional compatibility considerations (LiftMaster): when checking signal strength in CAPXS admin mode, LiftMaster recommends at least two bars. If using a Wi-Fi signal strength tool or app, a continuous signal strength of at least -65 dBm at the CAPXS must be guaranteed. Hidden network SSIDs are not supported, and Wi-Fi networks requiring secondary authentication (such as hotel and airport Wi-Fi) are not supported.

LiftMaster's illustration labels the Ethernet path (router/switch, modem, Ethernet cable, 325 feet [99.1 m] maximum) and a Wi-Fi signal graphic with three ranges: -30 to -67 dBm GOOD, -66 to -85 dBm POSSIBLE, and -86 dBm or weaker POOR.

CAPXS Access Control Wiring

LiftMaster's manual shows two example wiring setups: door access (page 15) and gate access (page 16). Both say to disconnect power BEFORE making electrical connections. The diagrams are not reproduced on this page; use the original manual pages for terminal-level connections, and the notes below, which LiftMaster prints on the diagrams.

Door Access (Page 15)

The labels on LiftMaster's door access example include: push button, door strike, maglock, proximity sensor, request to exit (REX), supervised (door status) with a supervised or non-supervised door sensor, Wiegand reader or keypad (DATA0 green, DATA1 white, ground, power), postal lock, primary relay, auxiliary relay (alarm bypass and a light), Ethernet connection, and power. The diagram itself is the authority for which device connects to which terminal.

• Maglock and door strike power: use a separate power supply (not provided). DO NOT use the controller's power supply for the maglock or the door strike. Use 18-22 AWG wire.
• Surge protection for the lock: for DC power, install a 1N4005 diode or equivalent. For AC power, install a Siemens S10K30MOV (metal oxide varistor) or equivalent.
• Supervised input: the diagram shows an end-of-line (EOL) resistor (1k ohm) with a supervised or non-supervised door sensor.
• Wiegand device wiring: keep the length of unshielded wires to a minimum to avoid electrical noise. For a KPR2000 keypad, wire the pink and black (ground) wires together.
• Light or load on the auxiliary relay: the diagram's labels include an isolation relay, a low voltage power supply, and the load, line, and neutral connections.
• UL evaluation: the maglock, door strike, and alarm bypass were not evaluated by UL.
• Postal lock: for more information on wiring a postal lock, refer to the manual for accessory CAPXSTKPL.
