Aiphone IX-DVF-4A vs 2N 01274-001: Specification Comparison
Both the Aiphone IX-DVF-4A and the 2N 01274-001 (IP Verso Black) are wired, PoE-powered video door stations designed for IP-based access control and intercom deployments — a category where installers routinely cross-shop Aiphone and 2N. The IX-DVF-4A is a four-call-button surface-mount unit targeting multi-tenant or multi-department entry points, while the 01274-001 is a modular main unit with an integrated camera and one expansion slot. Both support SIP, ONVIF, and two-way audio over standard Cat cable.

Which unit delivers better video and audio capability at the door?
The IX-DVF-4A publishes a defined camera specification: 1.23 MP on a 1/3" CMOS sensor with a minimum illumination of 5 lux, supporting H.264/AVC and Motion JPEG codecs. Tilt is field-adjustable to +15°, 0°, or −8°, giving installers flexibility for mounting height. Audio codecs are G.711 and G.722, the latter offering wideband (HD) voice quality.
The 01274-001 spec sheet lists H.264 and MJPEG as its compression formats, matching the IX-DVF-4A's codec set. The unit also notes H.265 in marketing copy, but the structured spec fields confirm H.264/MJPEG — buyers should verify with 2N documentation before assuming H.265 support. Camera resolution, sensor size, and minimum illumination are not provided in the available specs for the 01274-001. Audio is described only as 'built-in mic' with two-way support; no codec is listed. The IX-DVF-4A provides significantly more verifiable video and audio detail.
Which unit better supports multi-tenant or multi-directory call routing and physical access control?
The IX-DVF-4A is purpose-built for multi-party entry: it ships with four labeled call buttons and individual directory support, making it directly suited to small multi-tenant buildings, office suites, or departmental lobbies without additional hardware. It also provides two contact outputs and two trigger inputs onboard, enabling direct door-release relay or third-party device triggering.
The 01274-001 is a modular main unit with a 2-position frame (one position reserved for add-on modules). Call button count and directory capacity are not specified in the available data — these depend on which modules are added. Contact I/O specs are likewise absent from the provided information. For buyers who need defined, out-of-box multi-call capability, the IX-DVF-4A's four-button configuration is verifiable; the 01274-001's capacity requires confirmation of module selection.
Which unit is better suited for harsh outdoor environments and demanding installation conditions?
Both units carry IK08 impact resistance. The IX-DVF-4A adds IP65 ingress protection and a rated operating range of −40°F to 140°F, making it explicitly qualified for extreme cold and heat — relevant for exposed outdoor vestibules or harsh industrial environments. Power options include PoE (IEEE 802.3af Class 0) at 5.28 W draw, or 24 V DC as a fallback, giving installers flexibility where PoE infrastructure is absent. Port security via IEEE 802.1x is also specified.
The 01274-001 lists PoE (802.3af) as its power source. IP ingress rating, operating temperature range, and power draw in watts are not provided in the available specs. IK08 impact resistance is confirmed. The absence of a published IP rating and temperature range makes environmental suitability harder to verify for the 2N unit without consulting the full manufacturer datasheet.
Which should you choose: the IX-DVF-4A or the 01274-001?
Our take: The IX-DVF-4A is the stronger choice when a buyer needs a fully specified, multi-call outdoor video door station with verified environmental ratings. First, it ships with four labeled call buttons and onboard I/O (two contact outputs, two trigger inputs), whereas the 01274-001's call capacity and I/O require unspecified add-on modules. Second, the IX-DVF-4A carries confirmed IP65 and an operating range of −40°F to 140°F; the 01274-001 provides neither figure in the available specs. Third, the IX-DVF-4A's camera is fully documented at 1.23 MP / 5 lux / field-adjustable tilt, while the 2N unit lists no camera resolution, sensor, or illumination threshold. The 01274-001 may suit deployments already committed to the 2N IP Verso modular ecosystem where expansion flexibility and Bluetooth access (listed in specs) are priorities — but buyers must confirm environmental ratings and module choices directly with 2N before specifying it for harsh outdoor use.

Frequently Asked Questions
Which should you choose: the IX-DVF-4A or the 01274-001?
The IX-DVF-4A is the stronger choice when a buyer needs a fully specified, multi-call outdoor video door station with verified environmental ratings. First, it ships with four labeled call buttons and onboard I/O (two contact outputs, two trigger inputs), whereas the 01274-001's call capacity and I/O require unspecified add-on modules. Second, the IX-DVF-4A carries confirmed IP65 and an operating range of −40°F to 140°F; the 01274-001 provides neither figure in the available specs. Third, the IX-DVF-4A's camera is fully documented at 1.23 MP / 5 lux / field-adjustable tilt, while the 2N unit lists no camera resolution, sensor, or illumination threshold. The 01274-001 may suit deployments already committed to the 2N IP Verso modular ecosystem where expansion flexibility and Bluetooth access (listed in specs) are priorities — but buyers must confirm environmental ratings and module choices directly with 2N before specifying it for harsh outdoor use.
Is the IX-DVF-4A or 01274-001 better for a small multi-tenant building with four separate units?
The IX-DVF-4A is the more directly verifiable option: it ships with four labeled call buttons and individual directory support as standard, requiring no additional modules. The 01274-001's call button count depends on which expansion modules are selected — that information is not available in the current spec sheet, so buyers should confirm module requirements and total cost with 2N before specifying it for a four-tenant application.
Can either unit be installed in an exposed outdoor location in a cold climate?
The IX-DVF-4A is explicitly rated for −40°F to 140°F with IP65 ingress protection and IK08 impact resistance, making it a confirmed fit for harsh outdoor environments. The 01274-001 lists IK08 but provides no IP ingress rating or operating temperature range in the available specifications. Buyers should obtain the full 2N datasheet (referenced as /content/product-datasheets/01274-001.pdf) to verify outdoor suitability before installation.
Does either unit work without a dedicated PoE switch — for example, where only a 24 V DC power supply is available?
Yes, but only the IX-DVF-4A. It supports both PoE (IEEE 802.3af Class 0, 5.28 W) and 24 V DC power, giving installers a fallback when PoE infrastructure is unavailable. The 01274-001 lists PoE (802.3af) as its only stated power source; no secondary DC input option is documented in the available specs.
