ACTi A952 vs i-PRO X66700-Z3S: Specification Comparison
Both the ACTi A952 and the i-PRO WV-X66700-Z3S are 8MP (4K) outdoor PTZ dome cameras aimed at large-area perimeter surveillance and city-scale deployment. They share a common resolution class, outdoor IP66/IK10 environmental rating, PoE++ power, H.265/H.264/MJPEG compression, ONVIF multi-profile compliance, and onboard edge analytics. A buyer comparing them is typically evaluating optical reach, low-light capability, analytics depth, PTZ speed, and long-term ecosystem fit.

How do the imaging specs compare?
On sensor and optics the two cameras diverge significantly. The ACTi A952 uses a 1/1.8-inch CMOS sensor — a larger format than the i-PRO's 1/2.8-inch CMOS — which generally supports better light-gathering per pixel. The A952 delivers 22x optical zoom over a 6.4–138.5 mm focal range, an IR range of 250 m, and a minimum color illumination of 0.002 lux (0 lux B/W with IR). Its Extreme WDR is rated at 150 dB. The i-PRO WV-X66700-Z3S offers 30x optical zoom across 4.5–135 mm, a published DORI identify range of 352 m at telephoto, and a minimum illumination of 0.1 lux (B/W); no color lux figure is provided in the supplied specs. Its Super Dynamic WDR reaches 132 dB.
In raw low-light numbers the A952's 0.002 lux color floor substantially undercuts the i-PRO's 0.1 lux B/W figure — an 18 dB+ advantage in sensitivity — and its WDR rating is 18 dB higher (150 dB vs 132 dB). The i-PRO counters with a larger optical zoom ratio (30x vs 22x) and a published DORI identify distance of 352 m, compared to the A952's specified 250 m IR range. The i-PRO also includes a built-in gyro-based electronic image stabilizer and Active ClearSight lens coating; neither feature is listed in the A952 spec sheet. Both cameras produce up to 30 fps at 3840×2160.
What about installation and environment?
Both cameras share IP66 ingress protection and IK10 vandal resistance with metal/aluminum die-cast construction. The i-PRO WV-X66700-Z3S operates from −50°C to +60°C and is rated for wind resistance up to 40 m/s (~89 mph); it also carries a NEMA-TS2 certification and NEMA 4X implied by IP66. The ACTi A952 operates from −40°C to +50°C with an integral heater active — a 10°C narrower cold-weather floor and a 10°C lower upper limit than the i-PRO. For installations in extreme cold or high-ambient-heat environments, the i-PRO's wider temperature envelope is a concrete differentiator.
Power requirements also differ. The A952 draws up to 60 W via PoE++ (IEEE 802.3bt Type 3, Class 6) and also accepts AC 24V; the i-PRO draws 37.8 W via PoE++ (802.3bt), making it meaningfully less demanding on the switch budget per port. The A952 specifies five mount types (wall, pole, pendant, corner, rack); the i-PRO spec sheet does not enumerate mount accessory types. The i-PRO weighs approximately 3 kg; the A952 is approximately 3.92 kg. The i-PRO's dimensions are φ167 mm × 205 mm (H); equivalent dimensions are not provided in the A952 spec.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile S/G/T/M compliant, making them broadly compatible with enterprise VMS platforms. The i-PRO WV-X66700-Z3S lists support for SNMPv1/v2/v3, MQTT, SRTP, NTCIP, and IPv6 alongside a full IPv4 protocol stack, and supports up to 14 simultaneous users. The A952 spec sheet lists Gigabit Ethernet (10/100/1000 Base-T) while the i-PRO is rated at 10/100 Base-TX only — relevant if the integrator wants to future-proof the uplink or push high-bitrate streams. The i-PRO supports microSDXC cards up to 512 GB; no onboard SD card storage is listed for the A952.
On analytics, the A952 includes a dedicated Deep Learning Processing Unit (DLPU) running face detection, ALPR (automatic license plate recognition), and people counting at the edge. The i-PRO WV-X66700-Z3S provides AI VMD, AI face detection, scene change detection, and AI sound classification (gunshot, yell, vehicle horn, glass break) — an audio-event layer the A952 spec does not list. Both cameras support two-way audio with line-level input and output. The i-PRO offers 256 preset positions, auto-track, auto-pan, preset sequence, and patrol modes; the A952 spec does not enumerate a preset count. For ALPR at the edge, the A952 is the only one of the two with that capability listed in spec.
Which should you choose: the A952 or the X66700-Z3S?
Our take: The i-PRO WV-X66700-Z3S is the stronger choice when optical reach, extreme operating temperature (down to −50°C), lower power draw, and a richer network-protocol stack are the deciding factors. Its 30x zoom vs the A952's 22x zoom extends the DORI identify range to a published 352 m, and its 37.8 W consumption is 22 W less than the A952's 60 W — a meaningful PoE budget saving across a large deployment. However, the ACTi A952 holds concrete advantages in low-light sensitivity (0.002 lux color vs the i-PRO's 0.1 lux B/W), WDR headroom (150 dB vs 132 dB), Gigabit Ethernet uplink, and onboard ALPR — a capability absent from the i-PRO spec. Choose the A952 for sites requiring edge ALPR, superior low-light performance, or Gigabit LAN uplink; choose the i-PRO X66700-Z3S for wider-temperature environments, longer optical zoom reach, lower power budgets, and AI sound classification.

Frequently Asked Questions
Which should you choose: the A952 or the X66700-Z3S?
The i-PRO WV-X66700-Z3S is the stronger choice when optical reach, extreme operating temperature (down to −50°C), lower power draw, and a richer network-protocol stack are the deciding factors. Its 30x zoom vs the A952's 22x zoom extends the DORI identify range to a published 352 m, and its 37.8 W consumption is 22 W less than the A952's 60 W — a meaningful PoE budget saving across a large deployment. However, the ACTi A952 holds concrete advantages in low-light sensitivity (0.002 lux color vs the i-PRO's 0.1 lux B/W), WDR headroom (150 dB vs 132 dB), Gigabit Ethernet uplink, and onboard ALPR — a capability absent from the i-PRO spec. Choose the A952 for sites requiring edge ALPR, superior low-light performance, or Gigabit LAN uplink; choose the i-PRO X66700-Z3S for wider-temperature environments, longer optical zoom reach, lower power budgets, and AI sound classification.
Is the ACTi A952 or the i-PRO X66700-Z3S better for low-light performance?
Based on published specs, the ACTi A952 has a substantially lower minimum color illumination of 0.002 lux (0 lux B/W with IR active) versus the i-PRO X66700-Z3S's listed minimum of 0.1 lux (B/W only). The A952 also carries a higher WDR rating of 150 dB versus the i-PRO's 132 dB Super Dynamic. If low-light sensitivity is the primary criterion, the A952's published specs indicate a clear advantage.
Which camera has more optical zoom — the A952 or the X66700-Z3S?
The i-PRO WV-X66700-Z3S offers 30x optical zoom across a 4.5–135 mm focal range, plus up to 90x digital extra zoom at reduced resolution. The ACTi A952 provides 22x optical zoom over a 6.4–138.5 mm range plus 10x digital zoom. For maximum telephoto reach on a single optical axis, the i-PRO's 30x ratio and published DORI identify distance of 352 m at telephoto exceeds the A952's specified 250 m IR range.
Can either camera perform license plate recognition (ALPR) at the edge without a separate server?
Yes — the ACTi A952 lists onboard Automatic License Plate Recognition (ALPR) as a native edge analytic running on its built-in DLPU. The i-PRO WV-X66700-Z3S does not list ALPR in its published specifications; its edge analytics are limited to AI VMD, AI face detection, scene change detection, and AI sound classification. If edge ALPR without an external analytics server is required, the A952 is the only option of these two cameras.
