Aiphone IX-MV7-B vs Aiphone IXG-MK: Specification Comparison
Both the Aiphone IX-MV7-B and IXG-MK are IP-based video intercom stations designed for enterprise and commercial access-control environments — specifically, master and guard station roles within SIP-compatible IX/IXG-series systems. Each features a 7-inch touchscreen, PoE power, H.264 video compression, and two-way audio, positioning them as credible cross-shop candidates for integrators selecting a central operator console. This comparison evaluates them across display and video capability, power and physical footprint, and protocol/integration depth.

Which station delivers better display and video capability for operator monitoring?
The IX-MV7-B specifies a 7-inch LCD at 480p camera resolution with a minimum illumination of 5 lux and dual video codec support (H.264/AVC and Motion JPEG). The IXG-MK's marketing tagline references 720p video and H.264/MJPEG compression, which would represent a meaningful step up in incoming video clarity for visitor verification — however, the IXG-MK's formal spec fields list only 'H.264' and 'MJPEG' under compression without confirming a native camera resolution in the structured data; the 720p figure appears only in unverified tagline copy.
The IX-MV7-B's 480p figure is a confirmed spec. If the IXG-MK's 720p claim is accurate, it offers sharper visitor images at the guard desk — a relevant advantage in lobby or security-office deployments where facial recognition at the station matters. Buyers requiring a verified resolution figure should request Aiphone's IXG-MK datasheet (referenced at /content/product-datasheets/IXG-MK.pdf) before finalizing a decision.
How do power budget and physical dimensions compare for installation planning?
Both stations are powered via PoE IEEE 802.3af. The IX-MV7-B draws a confirmed 4.32W (Class 0), well within the 15.4W 802.3af ceiling and compatible with nearly any managed PoE switch port. The IXG-MK specifies PoE 802.3af with a ceiling of less than 13W — a notably higher upper bound that may require switch-port budget planning in dense deployments, though actual draw under normal operation may be lower; no confirmed idle or typical draw figure is provided.
Dimensionally, the IX-MV7-B measures 6-3/4" H × 8-11/16" W × 1-1/4" D, making it a slimmer wall-mount profile. The IXG-MK is larger at 8-1/16" H × 11" W × 2-3/16" D and supports both wall and rack mounting (stand included), with Cat-5e or Cat-6 wiring specified. The IX-MV7-B's operating temperature range is confirmed at 32°–104°F (0°–40°C); no operating temperature range is listed in the IXG-MK's provided specs.
Which station offers deeper protocol support and system integration features?
The IX-MV7-B carries an extensive, explicitly verified protocol stack: IPv4, IPv6, TCP, UDP, SIP, HTTP, HTTPS, RTSP, RTP, RTCP, IGMP, MLD, SMTP, SFTP, DHCP, NTP, and DNS. It also specifies IEEE 802.1x port security, two contact outputs, four trigger inputs, an 8Ω/0.5W speaker, 600Ω audio input, and a 500-entry station address book with 50 bell-schedule events per day and 8 speed-dial buttons. These parameters give integrators precise wiring and programmability data.
The IXG-MK confirms ONVIF compliance — a spec absent from the IX-MV7-B's listed data — and supports call recording (storage capacity field). Its audio modes include both VOX/handset and hands-free full-duplex plus push-to-talk, consistent with a dedicated guard-desk role. However, the IXG-MK's structured spec sheet does not enumerate individual IP protocols, contact outputs, trigger inputs, or address-book depth, leaving integrators to consult the Aiphone datasheet for those parameters.
Which should you choose: the IX-MV7-B or the IXG-MK?
Our take: The IX-MV7-B is the stronger choice when protocol transparency, low confirmed power draw, and programmable I/O depth are the deciding factors. Its 4.32W confirmed draw versus the IXG-MK's up-to-13W ceiling gives clearer PoE switch-budget certainty; its 16-protocol stack and IEEE 802.1x port security are fully enumerated; and its two contact outputs plus four trigger inputs are explicitly specified where the IXG-MK provides none of those figures. The IXG-MK counters with confirmed ONVIF compliance (absent from IX-MV7-B specs), call-recording capability, rack-mount flexibility, and a 720p video claim — though that resolution is unverified in structured spec fields. Choose the IX-MV7-B for feature-rich SIP master-station roles where I/O control and protocol depth matter; choose the IXG-MK for dedicated guard-desk or security-office posts where ONVIF interoperability and call-recording are operational requirements.

Frequently Asked Questions
Which should you choose: the IX-MV7-B or the IXG-MK?
The IX-MV7-B is the stronger choice when protocol transparency, low confirmed power draw, and programmable I/O depth are the deciding factors. Its 4.32W confirmed draw versus the IXG-MK's up-to-13W ceiling gives clearer PoE switch-budget certainty; its 16-protocol stack and IEEE 802.1x port security are fully enumerated; and its two contact outputs plus four trigger inputs are explicitly specified where the IXG-MK provides none of those figures. The IXG-MK counters with confirmed ONVIF compliance (absent from IX-MV7-B specs), call-recording capability, rack-mount flexibility, and a 720p video claim — though that resolution is unverified in structured spec fields. Choose the IX-MV7-B for feature-rich SIP master-station roles where I/O control and protocol depth matter; choose the IXG-MK for dedicated guard-desk or security-office posts where ONVIF interoperability and call-recording are operational requirements.
Is the IX-MV7-B or IXG-MK better for larger deployments with many door stations?
The IX-MV7-B specifies a 500-entry station address book and 8 speed-dial buttons, giving operators structured access to a large number of endpoints from a single master station. The IXG-MK does not list an address-book capacity or speed-dial count in the provided specs, so a direct numerical comparison cannot be made. Integrators planning large deployments should verify IXG-MK address-book limits against Aiphone's published datasheet before committing.
Which station is easier to integrate with third-party VMS or access-control platforms?
The IXG-MK explicitly confirms ONVIF compliance, which is the most widely used interoperability standard for VMS and access-control integration. The IX-MV7-B does not list ONVIF in its provided specs, though it carries a broad SIP and RTSP/RTP protocol stack that supports many IP-based integrations. If ONVIF certification is a hard requirement for your platform, the IXG-MK has a confirmed advantage.
Can both stations be rack-mounted in a security control room?
The IXG-MK explicitly supports wall and rack mounting with a stand included, making it purpose-designed for security-room installation. The IX-MV7-B's spec sheet lists only wall-mount dimensions (6-3/4" H × 8-11/16" W × 1-1/4" D) and does not reference rack mounting; buyers who need a rack-integrated guard console should favor the IXG-MK or confirm alternative mounting options with Aiphone.
