ACTi A952 vs i-PRO X66700-Z3LS: Specification Comparison
Both the ACTi A952 and i-PRO WV-X66700-Z3LS are outdoor 8MP PTZ cameras targeting professional physical-security installations requiring long-range optical zoom, edge analytics, and all-weather resilience. The A952 is an outdoor speed dome offering 22x optical zoom and onboard deep-learning analytics, while the X66700-Z3LS is a 4K rapid-PTZ dome featuring 30x optical zoom and an Ambarella CV22 SoC. Buyers comparing these two are evaluating zoom reach, PTZ speed, AI capability, low-light performance, and VMS ecosystem fit for wide-area or perimeter surveillance deployments.

How do the imaging specs compare?
Both cameras resolve 8MP (3840×2160) at up to 30 fps. The ACTi A952 uses a 1/1.8" CMOS sensor with a 6.4–138.5 mm lens delivering 22x optical zoom and a minimum color illumination of 0.002 lux, with IR effective to 250 m. Its Extreme WDR is rated at 150 dB. The i-PRO X66700-Z3LS uses an approx. 1/2.8" CMOS sensor with a 4.5–135 mm lens delivering 30x optical zoom (extendable to 90x extra zoom at 1280×720), a minimum color illumination of 0.13 lux, and IR effective to 280 m at 30 IRE / 200 m at 50 IRE. The i-PRO's Super Dynamic WDR is rated at a maximum of 132 dB at level 31.
On low-light sensitivity the A952 has a clear numeric advantage: 0.002 lux color versus 0.13 lux color for the X66700-Z3LS—a 65× difference in rated sensitivity. The X66700-Z3LS counters with greater optical zoom reach (30x vs 22x) and published DORI figures: at tele, identification range is 352 m and detection range is 3,519.7 m. The A952 does not publish DORI distances in its provided specifications. The X66700-Z3LS also includes a built-in gyro-based image stabilizer; no image stabilizer is listed for the A952.
What about installation and environment?
Both cameras carry IP66 and IK10 ratings, confirming dust-tight enclosures and resistance to high-pressure water jets alongside IEC 62262 impact protection. The i-PRO X66700-Z3LS additionally holds NEMA 4X certification and a wind resistance specification of up to 40 m/s (approx. 89 mph), neither of which appears in the A952's provided specifications. The A952 is rated for –40°C to +50°C (with integral heater), while the X66700-Z3LS is rated for –30°C to +60°C—the A952 tolerates 10°C colder at the low end, and the X66700-Z3LS tolerates 10°C warmer at the high end.
Power delivery differs: the A952 draws up to 60 W via PoE++ (IEEE 802.3bt Type 3, Class 6) or AC 24 V, while the X66700-Z3LS draws 45.9 W via PoE++ (also PoE Class 6). The lower wattage of the X66700-Z3LS may reduce infrastructure load on mid-span injectors. The A952 specifies Wall, Pole, Pendant, Corner, and Rack mounting options; the X66700-Z3LS mounting options are not detailed in the provided specifications. The A952 weighs approximately 3,920 g; the X66700-Z3LS weighs approximately 3,000 g. The X66700-Z3LS enclosure is aluminum die cast with a polycarbonate dome; the A952 enclosure material is not specified in the provided data beyond its IK10 metal casing certification.
Which fits your VMS and analytics better?
Both cameras are ONVIF-compliant across Profiles S, G, T, and M, providing broad VMS interoperability. Both encode H.265, H.264, and MJPEG. The X66700-Z3LS additionally supports SRTP and MQTT, publishes IPv6 protocol support explicitly, and supports up to 14 simultaneous streams. The A952's provided specifications do not list a simultaneous-user count, SRTP, MQTT, or explicit IPv6 stack details. The X66700-Z3LS network interface is rated 10/100 Base-TX; the A952 supports 10/100/1000 Base-T (Gigabit Ethernet), which may benefit high-bitrate 4K streaming on wired infrastructure.
On edge analytics the A952 lists a dedicated DLPU running face detection, ALPR (Automatic License Plate Recognition), people counting, and VMD. The X66700-Z3LS (Ambarella CV22 SoC) lists AI motion detection, privacy masking, face detection, people detection, vehicle detection, and AI Sound Classification (gunshot, yell, vehicle horn, glass break)—the last feature is not present in the A952's provided specifications. Both cameras support two-way audio; the X66700-Z3LS specifies 3.5 mm stereo mini-jack input and output plus G.726, G.711, and AAC-LC compression. The A952 lists line-in and line-out audio but does not specify connector type or audio compression codecs in the provided specifications. Both support onboard microSD/SDXC storage (the X66700-Z3LS specifies up to 512 GB microSDXC; the A952's card capacity is not listed in the provided specifications). The A952 carries a 3-year warranty (1 year under continuous motion); the X66700-Z3LS carries a 5-year warranty.
Which should you choose: the A952 or the X66700-Z3LS?
Our take: The i-PRO X66700-Z3LS is the stronger choice when raw PTZ speed, longer zoom reach, richer protocol support, and a longer warranty are the primary decision criteria. The X66700-Z3LS delivers 30x optical zoom versus the A952's 22x, preset pan speed of 700°/s versus 300°/s, and a published DORI identification range of 352 m at tele—specs absent from the A952's provided data. Its 5-year warranty also exceeds the A952's 3-year term. However, the ACTi A952 holds a meaningful advantage in rated low-light sensitivity (0.002 lux color versus 0.13 lux), operates 10°C colder (–40°C floor), includes ALPR at the edge—not listed for the X66700-Z3LS—and provides Gigabit Ethernet versus the i-PRO's Fast Ethernet. Specify the A952 where extreme cold, ALPR, or very low ambient light conditions are primary; specify the X66700-Z3LS where rapid tracking speed, extended zoom reach, NEMA 4X rating, or AI sound classification are required.

Frequently Asked Questions
Which should you choose: the A952 or the X66700-Z3LS?
The i-PRO X66700-Z3LS is the stronger choice when raw PTZ speed, longer zoom reach, richer protocol support, and a longer warranty are the primary decision criteria. The X66700-Z3LS delivers 30x optical zoom versus the A952's 22x, preset pan speed of 700°/s versus 300°/s, and a published DORI identification range of 352 m at tele—specs absent from the A952's provided data. Its 5-year warranty also exceeds the A952's 3-year term. However, the ACTi A952 holds a meaningful advantage in rated low-light sensitivity (0.002 lux color versus 0.13 lux), operates 10°C colder (–40°C floor), includes ALPR at the edge—not listed for the X66700-Z3LS—and provides Gigabit Ethernet versus the i-PRO's Fast Ethernet. Specify the A952 where extreme cold, ALPR, or very low ambient light conditions are primary; specify the X66700-Z3LS where rapid tracking speed, extended zoom reach, NEMA 4X rating, or AI sound classification are required.
Is the ACTi A952 or i-PRO X66700-Z3LS better for low-light surveillance?
Based on the provided specifications, the ACTi A952 has a substantially lower minimum color illumination rating of 0.002 lux versus 0.13 lux for the i-PRO X66700-Z3LS—a difference of approximately 65×. The A952 also specifies 250 m IR range compared to 280 m (at 30 IRE) for the X66700-Z3LS. If rated lux sensitivity is the deciding factor, the A952 has the spec advantage; however, lux ratings can reflect different measurement methodologies, and real-world performance should be validated in context.
Which camera has faster PTZ movement for tracking fast-moving subjects?
The i-PRO X66700-Z3LS specifies a preset pan speed of 700°/s and a preset tilt speed of 500°/s. The ACTi A952 specifies a preset speed of 300°/s (pan and tilt combined per the provided data). For applications requiring rapid repositioning to presets—such as license-plate capture triggers or active tracking of fast-moving vehicles—the X66700-Z3LS has a documented speed advantage of 700°/s pan versus 300°/s.
Can either camera perform license plate recognition without a separate server?
Yes, the ACTi A952 lists Automatic License Plate Recognition (ALPR) as an onboard edge analytic powered by its built-in DLPU. The i-PRO X66700-Z3LS's provided specifications do not include ALPR among its listed AI analytics (which cover face, people, vehicle detection, and AI sound classification). If edge ALPR without an external analytics server is required, the A952 is the only one of the two with that capability documented in the supplied specifications.
