i-PRO S66700-Z3L vs i-PRO X66700-Z3LS: Specification Comparison
Both the i-PRO WV-S66700-Z3L and WV-X66700-Z3LS are 8MP (4K) outdoor PTZ dome cameras sharing the same optical platform — 30x motorized zoom, 280m IR, and AI analytics. They occupy the same resolution class and camera type, making them a direct cross-shop decision for installers evaluating i-PRO's S-series versus X-series PTZ lineup. Key differences emerge in operating temperature floor, network protocol depth, NEMA rating, and I/O terminal configuration rather than in core imaging performance.

How do the imaging specs compare?
Both cameras share an identical imaging core: a 1/2.8-type CMOS sensor with a 5.57 × 3.13 mm scanning area, 30x motorized optical zoom (4.5–135mm, F1.8–F4.7), 90x extra zoom at 1280×720, and identical DORI figures — Detect 3,519.7m tele, Identify 352.0m tele. Minimum color illumination is 0.13 lux on both; the X66700-Z3LS explicitly states 0 lux (B/W with IR) while the S66700-Z3L lists ICR as 'Off/On/Auto with IR modes,' implying the same capability but without quoting a 0 lux figure in its spec sheet. Both deliver Max 132 dB WDR (Super Dynamic On, Level 31), the same shutter range (1/30–1/10000), and 280m IR at 30IRE / 200m at 50IRE.
Pan/tilt mechanics are spec-identical: 360° endless pan, -20° to +90° tilt, manual 0.065–150°/s, preset 700°/s pan and 500°/s tilt, 256 preset positions, and the same Auto Track/Auto Pan/Preset Sequence/Patrol auto modes. Both carry an Ambarella CV22 SoC, built-in gyro-based image stabilizer, Active ClearSight, and support resolutions from 3840×2160 down to 320×180 in H.265/H.264/MJPEG. The X66700-Z3LS explicitly adds a vertical FOV figure (1.4°–37°) not present in the S66700-Z3L spec sheet; both share the same horizontal FOV of 2.5°–62°.
What about installation and environment?
Physically, the cameras are dimensionally identical (φ167mm × 205mm H, SR 77.5mm dome radius, approx. 3 kg) with the same aluminum die-cast and polycarbonate dome finish, tamper-resistant enclosure, IK10 vandal resistance, IP66 ingress protection, and wind resistance up to 40 m/s. Power draw is identical: PoE++ (IEEE 802.3bt) at 45.9W (PoE Class 6). Both carry UL/c-UL, CE, IEC62368-1, FCC Part 15 Class A, ICES-003, EN55032/EN55035, and NEMA-TS2 certifications.
The most significant installation differentiator is operating temperature. The S66700-Z3L specifies -50°C storage / -30°C power-on to +60°C operational, giving it a -50°C cold-storage advantage but the same -30°C operational floor. The X66700-Z3LS states -30°C to +60°C operational with no separate power-on caveat listed. Additionally, the X66700-Z3LS adds NEMA 4X certification (corrosion/washdown resistance) not listed for the S66700-Z3L. External I/O differs: the S66700-Z3L lists 4 alarm I/O terminals (IN1, IN2, IN3, OUT) and 4x audio inputs (3.5mm stereo mini jack, -51 to -38dB); the X66700-Z3LS lists 3 alarm I/O terminals (IN1/2/3, OUT, AUX) with single audio input and output jacks (both ø3.5mm stereo).
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile G/M/S/T compliant and support H.265, H.264, and MJPEG compression with Smart Coding, up to 14 simultaneous users, and microSD/SDHC/SDXC edge storage. The X66700-Z3LS provides a substantially expanded protocol list: IPv6 support (DHCPv6, MLD), RTSP, SRTP, MQTT, NTCIP, DDNS, UPnP, SNMPv1/v2/v3, and IGMP — none of which appear in the S66700-Z3L's listed protocol set (TCP/IP, UDP/IP, HTTP/HTTPS, SMTP, DNS, NTP, SNMP, DHCP, RTP). For deployments requiring MQTT-based IoT integration, NTCIP (traffic infrastructure), or IPv6 networks, the X66700-Z3LS is the specified-capable unit.
AI analytics overlap substantially — both detect AI motion, faces, people, vehicles, and classify sound events (gunshot, yell, vehicle horn, glass break). The S66700-Z3L's spec sheet additionally lists 'non-mask status' detection in its card content, though this does not appear in the formal spec block. The X66700-Z3LS lists 'occupancy' analytics in its card content. On-board storage capability is equivalent (microSDXC up to 512GB on X66700-Z3LS explicitly stated; S66700-Z3L lists microSDXC without a stated maximum capacity). Both support G.726, G.711, and AAC-LC audio compression with full-duplex operation. Browser compatibility (Edge, Firefox, Chrome) and mobile support (iOS 8.0+, Android) are identical. The S66700-Z3L explicitly lists FIPS 140-2 Level 3 compliance; this certification is not listed in the X66700-Z3LS spec sheet.
Which should you choose: the S66700-Z3L or the X66700-Z3LS?
Our take: The X66700-Z3LS is the stronger choice when protocol depth, NEMA 4X corrosion resistance, and explicit IPv6/MQTT/NTCIP network integration matter — for example, smart-city traffic deployments or washdown-environment installs. Concretely: (1) the X66700-Z3LS carries NEMA 4X certification not listed for the S66700-Z3L; (2) it explicitly supports SRTP, MQTT, NTCIP, RTSP, and IPv6 — none appearing in the S66700-Z3L protocol list; (3) the S66700-Z3L explicitly lists FIPS 140-2 Level 3 compliance and four audio input terminals versus one on the X66700-Z3LS, making it preferable for high-security government or multi-mic deployments. Core imaging, PTZ mechanics, power, physical dimensions, and DORI ranges are spec-identical on both units. Choose the S66700-Z3L for FIPS-required or multi-channel audio installations; choose the X66700-Z3LS for corrosion-rated, protocol-rich, or IPv6 network environments.

Frequently Asked Questions
Which should you choose: the S66700-Z3L or the X66700-Z3LS?
The X66700-Z3LS is the stronger choice when protocol depth, NEMA 4X corrosion resistance, and explicit IPv6/MQTT/NTCIP network integration matter — for example, smart-city traffic deployments or washdown-environment installs. Concretely: (1) the X66700-Z3LS carries NEMA 4X certification not listed for the S66700-Z3L; (2) it explicitly supports SRTP, MQTT, NTCIP, RTSP, and IPv6 — none appearing in the S66700-Z3L protocol list; (3) the S66700-Z3L explicitly lists FIPS 140-2 Level 3 compliance and four audio input terminals versus one on the X66700-Z3LS, making it preferable for high-security government or multi-mic deployments. Core imaging, PTZ mechanics, power, physical dimensions, and DORI ranges are spec-identical on both units. Choose the S66700-Z3L for FIPS-required or multi-channel audio installations; choose the X66700-Z3LS for corrosion-rated, protocol-rich, or IPv6 network environments.
Is the S66700-Z3L or X66700-Z3LS better for low-light performance?
Based on the provided specs, both cameras are effectively equivalent in low-light: identical 1/2.8-type CMOS sensors, 0.13 lux minimum color illumination, 280m IR range at 30IRE, and Max 132 dB WDR. The X66700-Z3LS explicitly states 0 lux (B/W with IR); the S66700-Z3L's spec sheet does not quote a 0 lux B/W figure, though it lists ICR Auto with IR modes, implying the same behavior. Neither unit has a documented low-light advantage over the other based on the supplied specifications.
Can the X66700-Z3LS be used in corrosive or washdown environments where the S66700-Z3L cannot?
The X66700-Z3LS is listed as IP66 and NEMA 4X rated. NEMA 4X adds protection against corrosion and external washdowns beyond the standard IP66 dust/rain rating. The S66700-Z3L's spec sheet lists IP66 and NEMA-TS2 (traffic signal cabinet standard) but does not list NEMA 4X. For washdown or corrosive-environment installations, the X66700-Z3LS is the specified-capable unit based on the provided data.
Which camera is required for FIPS 140-2 compliant government deployments?
The S66700-Z3L explicitly lists FIPS 140-2 Level 3 compliance in its security specifications. The X66700-Z3LS spec sheet does not list FIPS 140-2 certification. For deployments requiring FIPS 140-2 Level 3 cryptographic validation — common in U.S. federal and DoD procurement — the S66700-Z3L is the unit with the documented certification based on the provided specifications.
