ACTi Z952 vs i-PRO A-475-P: Specification Comparison
Both the ACTi Z952 and the i-PRO A-475-P are 4MP outdoor PTZ cameras powered over a single Ethernet cable via PoE 802.3af, making them credible cross-shop candidates for installers specifying motorized-zoom surveillance at parking structures, campuses, or perimeter fence lines. The Z952 leads on optical zoom range with a 25x motorized lens, while the A-475-P counters with broader certified VMS compatibility and native edge analytics. This comparison draws exclusively from the published specifications for each model.

How do the imaging specs compare?
Both cameras resolve 4MP. The ACTi Z952 uses a 4.8–120 mm motorized lens with 25x optical zoom and a maximum aperture of F1.5, which provides meaningful light-gathering advantage at longer focal lengths. The i-PRO A-475-P specifies a varifocal lens with 4x optical zoom; the exact focal-length range is not stated in the provided specifications. The Z952's F1.5 aperture is documented; no aperture figure is provided for the A-475-P.
Both cameras include IR night vision and both support WDR—though WDR is confirmed only for the Z952 in the supplied specs; the A-475-P spec set does not list a WDR specification. Both support H.265 and H.264 compression; the A-475-P additionally lists MJPEG. Maximum frame rate is stated as 30 fps for the Z952; no frame-rate figure is provided for the A-475-P. IR range is listed as 150 feet for the A-475-P; no IR distance figure is provided for the Z952.
What about installation and environment?
The ACTi Z952 carries an IP66 ingress-protection rating and an IK10 impact rating, confirming resistance to high-pressure water jets and heavy mechanical impact—relevant for exposed or vandal-prone outdoor installations. The i-PRO A-475-P specifies PoE 802.3af at a stated 13W draw; no IP or IK rating is listed in the provided specifications for the A-475-P.
Both cameras are powered by PoE 802.3af, eliminating a separate power run. The Z952 is described as a dome form factor with motorized pan-tilt; the A-475-P is described as a PTZ form factor. Operating temperature range is not stated in the provided specifications for either model. Mounting type for the A-475-P is listed as rack in the spec data, which appears inconsistent with a PTZ camera and should be verified against the manufacturer datasheet before installation planning.
Which fits your VMS and analytics better?
Both cameras declare ONVIF compliance. The i-PRO A-475-P explicitly lists ONVIF Profile S and names certified VMS platforms: i-PRO NVR, Milestone, Genetec, and Axis Camera Station. The ACTi Z952 lists ONVIF without specifying a profile or named VMS partners in the provided specifications.
The A-475-P includes Video Motion Detection (VMD) as a documented edge analytic; no analytics are listed for the Z952. Both cameras include an audio input. The ACTi Z952 specifies MicroSD on-board storage; no edge-storage specification is provided for the A-475-P. The A-475-P additionally lists audio streaming; the Z952 lists audio input only.
Which should you choose: the Z952 or the A-475-P?
Our take: The Z952 is the stronger choice when long-range optical reach and vandal-hardened housing are the primary requirements: its 25x optical zoom (4.8–120 mm, F1.5) substantially outpaces the A-475-P's 4x zoom, its IP66/IK10 housing is rated where the A-475-P provides no equivalent IP or IK figures, and its MicroSD slot enables local recording without a network dependency. The A-475-P holds the advantage where VMS ecosystem certainty matters: it names Milestone, Genetec, i-PRO NVR, and Axis Camera Station as certified platforms, carries ONVIF Profile S, includes documented VMD analytics, and offers a 150-foot IR range not specified for the Z952. Specify the Z952 for wide-area outdoor coverage with impact-resistance needs; specify the A-475-P where VMS certification and edge analytics are contractually required and zoom range is secondary.

Frequently Asked Questions
Which should you choose: the Z952 or the A-475-P?
The Z952 is the stronger choice when long-range optical reach and vandal-hardened housing are the primary requirements: its 25x optical zoom (4.8–120 mm, F1.5) substantially outpaces the A-475-P's 4x zoom, its IP66/IK10 housing is rated where the A-475-P provides no equivalent IP or IK figures, and its MicroSD slot enables local recording without a network dependency. The A-475-P holds the advantage where VMS ecosystem certainty matters: it names Milestone, Genetec, i-PRO NVR, and Axis Camera Station as certified platforms, carries ONVIF Profile S, includes documented VMD analytics, and offers a 150-foot IR range not specified for the Z952. Specify the Z952 for wide-area outdoor coverage with impact-resistance needs; specify the A-475-P where VMS certification and edge analytics are contractually required and zoom range is secondary.
Is the Z952 or A-475-P better for low light?
Based on available specs, the Z952 documents a maximum aperture of F1.5 at its widest focal length, which provides strong light-gathering capability. The A-475-P does not list an aperture value or minimum illumination figure in the provided specifications. Both cameras include IR illumination; the A-475-P specifies an IR range of 150 feet while no IR distance is stated for the Z952. A direct low-light comparison cannot be made without minimum-illumination lux values for both models.
Will either camera work with Milestone or Genetec?
The i-PRO A-475-P explicitly lists Milestone and Genetec as certified VMS platforms, along with ONVIF Profile S. The ACTi Z952 declares ONVIF compliance, which typically enables basic integration with Milestone and Genetec, but no named VMS certifications are listed in the provided specifications. Buyers requiring documented VMS certification should confirm ACTi's compatibility matrix directly with ACTi or Milestone/Genetec.
Which camera is better suited for a vandal-prone outdoor site?
The ACTi Z952 carries a published IK10 impact rating and IP66 weatherproofing, both confirmed in its specifications. The i-PRO A-475-P does not list an IP or IK rating in the provided specifications. For installations where physical impact resistance is a documented requirement—such as parking structures, transit stations, or publicly accessible perimeters—the Z952 provides a verifiable spec; the A-475-P's suitability for those environments cannot be confirmed from the available data alone.
