ACTi E911 vs Geovision VD3400-001U: Specification Comparison
Both the ACTi E911 and Geovision VD3400-001U are 3MP PoE dome cameras targeting indoor commercial and institutional deployments where a single-cable install and ONVIF VMS compatibility matter. The E911 positions as an indoor mini dome with wide-angle fixed optics and Extreme WDR, while the VD3400-001U is a vandal-proof dome with varifocal lens and IP67-rated weatherproof housing. Buyers comparing these are typically weighing optical flexibility and environmental hardening against wide-angle coverage and high-dynamic-range imaging in moderate-risk interior zones.

How do the imaging specs compare?
Both cameras deliver 3MP resolution. The ACTi E911 specifies a 2.1 mm fixed lens at F1.8 with a 117.5° horizontal field of view and a maximum frame rate of 1080p/60fps. Its WDR is rated 'Extreme WDR,' which ACTi applies to scenes with simultaneous bright and shadowed zones such as lobbies or retail floors. The Geovision VD3400-001U provides a 3–9 mm varifocal lens, allowing installers to dial in coverage angle on-site from a tight to a moderately wide field. Its WDR is listed as 'WDR Pro'; no maximum frame rate is specified in the provided data.
The VD3400-001U includes IR illumination with Day/Night switching, making it functional in zero-ambient-light conditions. The E911 specifications do not list IR or any minimum illumination figure, so low-light and no-light performance cannot be confirmed from the available data. Neither camera's specifications include a stated image sensor size or minimum lux rating.
What about installation and environment?
The ACTi E911 carries an IK08 impact rating and is described as an indoor camera; no IP ingress-protection rating is listed in the provided specifications. The Geovision VD3400-001U carries an IP67 rating, meaning it is rated for full dust exclusion and temporary water immersion, and is described as vandal-proof, though no IK numerical rating is listed in the provided data. IP67 makes the VD3400-001U suitable for covered outdoor or wet indoor environments; the E911's suitability for those conditions cannot be confirmed from available specs.
Both cameras are powered by PoE. The E911 explicitly specifies IEEE 802.3af with a draw under 13W. The VD3400-001U lists PoE without specifying the standard or wattage. Both support ceiling and wall mounting in a dome form factor. No operating temperature range is provided for either model in the supplied specifications.
Which fits your VMS and analytics better?
The ACTi E911 lists compatibility with 'Standard ONVIF IP platforms' and includes Video Analytics as an edge feature. It also supports onboard MicroSD/MicroSDXC storage for local recording or failover. Compression is H.265 and H.264. The Geovision VD3400-001U is listed as 'ONVIF compatible'; no edge analytics, audio, or onboard storage capability is specified in the provided data. Neither model lists audio input or output in the supplied specifications. Compression standard for the VD3400-001U is not stated in the provided specs.
Which should you choose: the E911 or the VD3400-001U?
Our take: The E911 is the stronger choice when the priority is wide-angle fixed coverage with high-dynamic-range imaging and edge analytics in a controlled indoor environment. The E911 delivers a 117.5° horizontal field of view from its 2.1 mm F1.8 fixed lens, an 802.3af PoE draw confirmed under 13W, and onboard MicroSD storage — none of which are specified for the VD3400-001U. Conversely, the VD3400-001U is the stronger choice when the site demands optical zoom flexibility, confirmed IR night vision, or environmental hardening: its 3–9 mm varifocal lens enables field-adjustable coverage, its IP67 rating confirms dust and water resistance, and its Day/Night IR supports zero-lux scenes — capabilities absent or unconfirmed in the E911's specs. Neither model's operating temperature, sensor size, or warranty is available in the provided data, so those factors cannot be compared here.

Frequently Asked Questions
Which should you choose: the E911 or the VD3400-001U?
The E911 is the stronger choice when the priority is wide-angle fixed coverage with high-dynamic-range imaging and edge analytics in a controlled indoor environment. The E911 delivers a 117.5° horizontal field of view from its 2.1 mm F1.8 fixed lens, an 802.3af PoE draw confirmed under 13W, and onboard MicroSD storage — none of which are specified for the VD3400-001U. Conversely, the VD3400-001U is the stronger choice when the site demands optical zoom flexibility, confirmed IR night vision, or environmental hardening: its 3–9 mm varifocal lens enables field-adjustable coverage, its IP67 rating confirms dust and water resistance, and its Day/Night IR supports zero-lux scenes — capabilities absent or unconfirmed in the E911's specs. Neither model's operating temperature, sensor size, or warranty is available in the provided data, so those factors cannot be compared here.
Is the E911 or VD3400-001U better for low light?
Based on the provided specifications, only the Geovision VD3400-001U lists IR illumination and Day/Night switching, making it the documented choice for low-light or no-light conditions. The ACTi E911 does not specify IR capability or a minimum lux rating in the available data, so its low-light performance cannot be confirmed from specs alone.
Which camera gives me more flexibility when I don't know the final coverage angle?
The Geovision VD3400-001U, with its 3–9 mm varifocal lens, allows the installer to adjust the field of view on-site after mounting. The ACTi E911 has a fixed 2.1 mm lens providing a set 117.5° horizontal field of view, so coverage angle is determined at the product-selection stage and cannot be changed post-installation.
Can either camera be used outdoors or in wet areas?
The Geovision VD3400-001U carries an IP67 rating, confirming protection against dust ingress and temporary water immersion, making it suitable for covered outdoor or damp indoor environments. The ACTi E911 is described as an indoor camera and no IP rating is listed in the provided specifications, so outdoor or wet-environment suitability cannot be confirmed for the E911 from available data.
