ACTi Z310 vs ACTi Z47: Specification Comparison
Both the ACTi Z310 and ACTi Z47 are 8MP (1440p/30fps) outdoor bullet IP cameras sharing the same resolution class, form factor, and PoE power delivery. The comparison centers on their key differentiators: fixed versus motorized varifocal optics, operating temperature range, impact resistance, and audio I/O type. Installers cross-shopping these two are typically choosing between a cost-efficient fixed-lens entry point for standard outdoor deployments and a ruggedized, remotely adjustable zoom unit suited to harsher or more demanding environments.

How do the imaging specs compare?
Both cameras deliver 8MP resolution at 30 fps in the 1440p format, and both implement WDR and IR-based low-light operation with Adaptive IR. The Z310 uses a fixed 2.8mm f/1.6 lens on a 1/2.8" sensor, providing a 99° horizontal field of view with no remote adjustment capability. The Z47 uses a motorized varifocal 2.8–12mm lens (4.3× zoom range), allowing installers or operators to remotely reframe the scene without a physical site visit. Focal length and angle of view for the Z47 at any given zoom setting are not specified in the provided data.
On low-light enhancement, the Z310 lists 'Adaptive IR; SLLS' (Super Low Light Sensitivity), while the Z47 lists 'Adaptive IR; Day/Night.' SLLS is a distinct low-light processing mode documented on the Z310; the Z47 does not list an equivalent in the provided specs. Neither camera's minimum illumination lux value is present in the supplied specifications for either unit, so a direct lux comparison cannot be made from this data. Both support H.265 and H.264 compression; the Z310 additionally supports MJPEG, which the Z47 does not list.
What about installation and environment?
Both cameras are IP67-rated for dust-tight and water-immersion protection and support 802.3af PoE, keeping infrastructure requirements identical in standard installations. The Z310 draws under 13W; the Z47 is rated at 12.95W maximum—effectively the same PoE class. Mounting options are comparable: the Z310 supports wall, soffit, and pole mounts; the Z47 supports wall, pole, and ceiling bracket.
The Z47 carries an IK10 impact rating, meaning it withstands 20-joule impacts per IEC 62262—relevant for sites with vandalism risk, industrial wash-down areas, or coastal installations with windborne debris. The Z310 has no IK rating listed in its specifications. Operating temperature is a significant differentiator: the Z310 is rated 0°C to 50°C, limiting it to moderate-climate deployments, while the Z47 is rated -40°C to 60°C (-40°F to 140°F), qualifying it for extreme cold or heat without an external heater enclosure.
Which fits your VMS and analytics better?
Both cameras declare ONVIF Profile S and Profile T compliance, ensuring broad VMS interoperability on current platforms. Neither camera's provided specifications include edge analytics capabilities (e.g., line crossing, intrusion detection), so no comparison on that dimension is possible from this data. On-board storage: the Z310 lists MicroSDHC/MicroSDXC as a local storage option; the Z47 does not list any edge storage capability in its specifications.
Audio I/O differs meaningfully: the Z310 has a built-in microphone (no external audio input listed), while the Z47 provides an audio input jack for an external microphone—no built-in microphone is listed for the Z47. Installations requiring audio capture with the Z47 will need a separate microphone wired to the camera's audio input. The Z310's built-in mic simplifies single-cable PoE deployments where audio is desired without additional hardware.
Which should you choose: the Z310 or the Z47?
Our take: The Z47 is the stronger choice when the site demands remote lens adjustment, extreme-temperature resilience, or vandal resistance; the Z310 is the more appropriate choice for standard-climate, fixed-angle deployments where simplicity and built-in audio matter. Three concrete spec deltas drive the decision: (1) the Z47's motorized 2.8–12mm varifocal lens versus the Z310's fixed 2.8mm eliminates the need for a site revisit to reframe coverage; (2) the Z47's -40°C to 60°C operating range extends coverage to environments where the Z310's 0°C to 50°C limit would require a heater enclosure; (3) the Z47's IK10 impact rating provides certified vandal resistance the Z310 lacks. Conversely, the Z310 offers on-board MicroSD storage and a built-in microphone—neither of which is listed for the Z47—making it preferable where local recording failover or single-cable audio capture is required on a temperate-climate site.

Frequently Asked Questions
Which should you choose: the Z310 or the Z47?
The Z47 is the stronger choice when the site demands remote lens adjustment, extreme-temperature resilience, or vandal resistance; the Z310 is the more appropriate choice for standard-climate, fixed-angle deployments where simplicity and built-in audio matter. Three concrete spec deltas drive the decision: (1) the Z47's motorized 2.8–12mm varifocal lens versus the Z310's fixed 2.8mm eliminates the need for a site revisit to reframe coverage; (2) the Z47's -40°C to 60°C operating range extends coverage to environments where the Z310's 0°C to 50°C limit would require a heater enclosure; (3) the Z47's IK10 impact rating provides certified vandal resistance the Z310 lacks. Conversely, the Z310 offers on-board MicroSD storage and a built-in microphone—neither of which is listed for the Z47—making it preferable where local recording failover or single-cable audio capture is required on a temperate-climate site.
Is the Z310 or Z47 better for low-light performance?
Both use Adaptive IR for night operation. The Z310 additionally lists SLLS (Super Low Light Sensitivity) as a low-light processing mode, which is not listed for the Z47. However, neither camera's minimum illumination value in lux is provided in the available specifications, so a quantified low-light comparison cannot be made from this data alone.
Can either camera be installed in a cold-storage or extreme outdoor environment?
The Z47 is rated for -40°C to 60°C, qualifying it for extreme cold or heat without supplemental heating. The Z310 is rated only 0°C to 50°C and would require a heater-equipped enclosure in sub-zero environments—adding cost and bulk to the installation.
Which camera is easier to adjust after installation if coverage needs change?
The Z47's motorized varifocal 2.8–12mm lens (4.3× zoom) can be adjusted remotely via the camera's interface, allowing framing changes without sending a technician back to the site. The Z310 has a fixed 2.8mm lens; any field-of-view change requires physically replacing the lens or repositioning the camera.
