i-PRO S66300-Z4 vs i-PRO X66300-Z3LS: Specification Comparison
Both the i-PRO WV-S66300-Z4 and WV-X66300-Z3LS are 2MP outdoor PTZ dome cameras built on the same 1/2.8-type CMOS sensor platform, sharing identical form factor dimensions and targeting wide-area perimeter surveillance. The S66300-Z4 differentiates primarily through a higher optical zoom ratio and longer detection range, while the X66300-Z3LS adds built-in IR illumination and a NEMA 4X environmental rating. This comparison evaluates imaging reach, installation requirements, and integration capabilities based solely on published specifications.

How do the imaging specs compare?
The WV-S66300-Z4 offers a 40x optical zoom spanning 4.25–170mm (F1.6–F4.95), yielding DORI detect and identify distances of 2,199.9m and 220.0m respectively at telephoto. An extra-zoom mode extends reach to 60x at 1280×720 resolution. The WV-X66300-Z3LS delivers a 32x optical zoom spanning 4.25–136mm (F1.6–F4.4), with DORI detect and identify distances of 1,833.2m and 183.3m at telephoto—approximately 17% shorter reach across all DORI tiers. Both cameras share an identical minimum illumination of 0.006 lux (B&W, 50IRE, F1.6, 1/30s) and identical 144dB dynamic range via Super Dynamic.
The X66300-Z3LS adds built-in IR LED illumination rated at 350m (30IRE), enabling passive low-light operation without supplemental lighting infrastructure. The S66300-Z4 has no built-in IR illuminator per its specifications (IR LED field shows '—'). The X66300-Z3LS also specifies a 60fps maximum frame rate; the S66300-Z4 lists frame rate as 'Variable' with no explicit maximum fps stated in the provided specifications. Both models support 1920×1080 maximum resolution, and the X66300-Z3LS additionally supports 4:3 aspect ratio resolutions including 2048×1536 per its spec sheet.
What about installation and environment?
Both cameras share identical physical dimensions (φ167mm × 205mm H, dome radius SR 77.5mm), weight (approximately 3kg without attachment), operating temperature range (−50°C to +60°C), humidity tolerance (10–100%, no condensation), IP66 dust and water resistance, IK10 impact resistance, and wind resistance up to 40m/s. Both use PoE++ (IEEE 802.3bt) Class 6 power. A key distinction: the X66300-Z3LS carries an additional NEMA 4X rating and specifies a stainless steel finish component alongside aluminum die-cast and polycarbonate dome, while the S66300-Z4 specifies aluminum die-cast and polycarbonate dome only. Power draw differs: the S66300-Z4 is rated at 37.8W versus 45.9W for the X66300-Z3LS, the higher draw on the X66300-Z3LS attributable in part to the IR illuminator.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile G/M/S/T compliant, support up to 14 simultaneous users, and share identical pan/tilt mechanical performance: 360° endless pan at 700°/s preset, tilt −20° to +90° at 500°/s preset, and 256 preset positions. Both support H.265/H.264/MJPEG compression, Smart Coding with variable GOP, and identical auto modes (auto track, auto pan, preset sequence, patrol). AI analytics on both include face, people, and vehicle detection plus AI sound classification (gunshot, yell, vehicle horn, glass break). The X66300-Z3LS specification explicitly lists mask and occupancy detection; the S66300-Z4 specification lists 'non-mask' and occupancy under enriched data fields. Both support microSDXC edge storage; the X66300-Z3LS specification explicitly states support up to 512GB.
Audio connectivity differs: the S66300-Z4 specifies four 3.5mm audio inputs (−51 to −38dB) and one audio output, plus four alarm terminals (3 in, 1 out). The X66300-Z3LS specifies one 3.5mm audio input, one audio output (600Ω), three alarm inputs, one alarm output, and one AUX output. The S66300-Z4 lists FIPS 140-2 Level 3 security compliance in its specification; the X66300-Z3LS specification does not list this standard. Both support IEEE 802.1X and HTTPS.
Which should you choose: the S66300-Z4 or the X66300-Z3LS?
Our take: The S66300-Z4 is the stronger choice when maximum optical reach and multi-channel audio input are the primary requirements. Its 40x zoom (vs. 32x) and 4.25–170mm focal length deliver a DORI detect range of 2,199.9m versus 1,833.2m on the X66300-Z3LS—a 366m advantage at telephoto. The S66300-Z4 also draws 8.1W less (37.8W vs. 45.9W), which matters when PoE++ budget is constrained across many drops, and it lists FIPS 140-2 Level 3 compliance for high-security deployments. Conversely, the X66300-Z3LS is the stronger choice when passive low-light coverage is required, given its 350m IR illuminator—the S66300-Z4 has no built-in IR per spec. The X66300-Z3LS also carries a NEMA 4X rating for corrosive or wash-down environments where IP66 alone may be insufficient. Both carry a 5-year warranty.

Frequently Asked Questions
Which should you choose: the S66300-Z4 or the X66300-Z3LS?
The S66300-Z4 is the stronger choice when maximum optical reach and multi-channel audio input are the primary requirements. Its 40x zoom (vs. 32x) and 4.25–170mm focal length deliver a DORI detect range of 2,199.9m versus 1,833.2m on the X66300-Z3LS—a 366m advantage at telephoto. The S66300-Z4 also draws 8.1W less (37.8W vs. 45.9W), which matters when PoE++ budget is constrained across many drops, and it lists FIPS 140-2 Level 3 compliance for high-security deployments. Conversely, the X66300-Z3LS is the stronger choice when passive low-light coverage is required, given its 350m IR illuminator—the S66300-Z4 has no built-in IR per spec. The X66300-Z3LS also carries a NEMA 4X rating for corrosive or wash-down environments where IP66 alone may be insufficient. Both carry a 5-year warranty.
Is the S66300-Z4 or X66300-Z3LS better for low-light surveillance without external lighting?
The X66300-Z3LS is the better choice for passive low-light operation: it includes a built-in IR illuminator rated at 350m (30IRE). The S66300-Z4 does not list a built-in IR illuminator in its specifications, so it would require external IR lighting infrastructure to maintain useful image quality in darkness.
Which camera covers a longer detection distance at full zoom?
The S66300-Z4 reaches a DORI detect distance of 2,199.9m (7,217.6ft) at telephoto, compared to 1,833.2m (6,014.4ft) for the X66300-Z3LS—a difference of approximately 366m. This results from the S66300-Z4's 40x zoom and 170mm maximum focal length versus the X66300-Z3LS's 32x zoom and 136mm maximum focal length.
Does the X66300-Z3LS have a higher environmental protection rating than the S66300-Z4?
Yes, in one respect. Both cameras are rated IP66 and IK10. However, the X66300-Z3LS additionally carries a NEMA 4X rating, which covers corrosion resistance and wash-down scenarios. The S66300-Z4 specification does not list a NEMA 4X rating, only IP66.
