i-PRO S61501-Z1 vs i-PRO S65501-Z1: Specification Comparison
The i-PRO WV-S61501-Z1 and WV-S65501-Z1 are both 5MP AI PTZ dome cameras built on the same Ambarella CV22 SoC, sharing a 1/2.8-type CMOS sensor, 10x motorized optical zoom, and identical AI analytics capabilities. The central distinction is deployment environment: the S61501-Z1 is rated for indoor use, while the S65501-Z1 carries IP66/IK10 ratings for outdoor installation. Buyers cross-shopping these models are typically deciding between an indoor PTZ and its hardened outdoor counterpart within the same product family.

How do the imaging specs compare?
Both cameras share a 1/2.8-type CMOS sensor with a 5.12mm × 3.84mm scanning area, identical 10x motorized optical zoom (4.7–47mm focal length), and the same minimum illumination of 0.004 lux in B&W mode. Maximum dynamic range is 132 dB on both, though the S65501-Z1 notes a frame-rate limitation above level 30 Super Dynamic (restricted to 15 fps), while the S61501-Z1 specifies Max. 132 dB at level 31 without that caveat. Both deliver the same DORI detection range of 92.4–945.4 m and recognition range of 18.5–189.1 m wide-to-tele.
PTZ movement specs diverge noticeably. The S61501-Z1 offers a 0–350° pan range at up to 350°/s preset speed and a –30° to +90° tilt range at 300°/s preset. The S65501-Z1 provides 360° endless pan at up to 500°/s preset speed (PoE+ powered) and a –15° to +195° tilt range at 500°/s preset (PoE+) or 300°/s (DC12V). Both support 256 preset positions and identical Auto Track, Auto Pan, Preset Sequence, and Patrol auto modes. The S61501-Z1 lists a vertical field of view of 3.5°–44°; the S65501-Z1 does not specify vertical FoV in its provided specs.
What about installation and environment?
The S61501-Z1 is an indoor-only camera with no IP or IK rating listed in its specifications. It operates from –10°C to +50°C (power-on threshold 0°C) and tolerates 10–90% relative humidity without condensation. Its housing is resin-bodied and measures ø117mm × 155mm (H), weighing approximately 1.2 kg. Power options are DC12V at 11.6W or PoE+ at 12.95W.
The S65501-Z1 is built for outdoor deployment with an IP66 dust/water rating, IK10 impact resistance (IEC 62262), wind resistance up to 40 m/s (~89 mph), an integrated Temish anti-condensation element, and NEMA TS2 compliance. It operates from –30°C to +55°C (power-on –20°C) and tolerates 10–100% relative humidity. Its aluminum die-cast and polycarbonate housing measures ø165mm × 139mm (H) at approximately 1.6 kg. Power options are DC12V at 15.4W, PoE at 12.95W, or PoE+ at 18.9W—with the higher PoE+ budget enabling the 500°/s preset pan speed.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile G/M/S/T compliant, support microSDXC edge storage, and provide identical AI analytics: AI Video Motion Detection, Face Detection, Vehicle Detection, and People Detection, plus AI Sound Classification for gunshot, yell, vehicle horn, and glass break. Both share the same alarm I/O structure (3× alarm input terminals, alarm output), 3.5mm stereo audio input and output jacks, and support up to 14 simultaneous users. Network interfaces are identical: 10Base-T/100Base-TX via RJ45, with full IPv4 and IPv6 protocol stacks including MQTT, SFTP, SNMP v1/v2/v3, and LLDP. Security posture is the same on both: FIPS 140-2 Level 3, GlobalSign certificate, HTTPS, and IEEE 802.1X.
A minor difference exists in the S65501-Z1's audio output spec, which explicitly states –20 dBV output level, while the S61501-Z1 lists only the 600Ω impedance without a dBV figure. The S61501-Z1 specifies its audio transmission modes as Off/Mic/Audio/Half-duplex/Full-duplex; the S65501-Z1 lists Off/Mic/Line/Half-duplex/Full-duplex—the substitution of 'Line' for 'Audio' reflects a labeling difference in the provided specs. Both support the same codecs: H.265, H.264 (CBR/VBR), and MJPEG at resolutions up to 3072×1728, with G.726 and G.711 audio compression.
Which should you choose: the S61501-Z1 or the S65501-Z1?
Our take: The S65501-Z1 is the clear choice for any outdoor or environmentally exposed deployment. Its IP66/IK10-rated aluminum die-cast housing, –30°C to +55°C operating range (versus –10°C to +50°C for the S61501-Z1), and wind resistance to 40 m/s give it a decisively broader installation envelope. Its 360° endless pan with 500°/s preset speed (under PoE+) also surpasses the S61501-Z1's 350° pan at 350°/s—a meaningful operational advantage for wide-area tracking. The S61501-Z1 is the appropriate choice for temperature-controlled indoor environments where the lighter resin housing, smaller footprint (ø117mm vs ø165mm), and lower PoE+ power draw (12.95W vs 18.9W) are advantages. Both cameras deliver identical AI analytics, ONVIF Profile G/M/S/T compliance, and 5MP resolution, so the decision reduces to environment and pan-speed requirements rather than image quality or integration capability.

Frequently Asked Questions
Which should you choose: the S61501-Z1 or the S65501-Z1?
The S65501-Z1 is the clear choice for any outdoor or environmentally exposed deployment. Its IP66/IK10-rated aluminum die-cast housing, –30°C to +55°C operating range (versus –10°C to +50°C for the S61501-Z1), and wind resistance to 40 m/s give it a decisively broader installation envelope. Its 360° endless pan with 500°/s preset speed (under PoE+) also surpasses the S61501-Z1's 350° pan at 350°/s—a meaningful operational advantage for wide-area tracking. The S61501-Z1 is the appropriate choice for temperature-controlled indoor environments where the lighter resin housing, smaller footprint (ø117mm vs ø165mm), and lower PoE+ power draw (12.95W vs 18.9W) are advantages. Both cameras deliver identical AI analytics, ONVIF Profile G/M/S/T compliance, and 5MP resolution, so the decision reduces to environment and pan-speed requirements rather than image quality or integration capability.
Is the S61501-Z1 or S65501-Z1 better for low-light performance?
Both cameras are spec-identical for low light: each uses a 1/2.8-type CMOS sensor with 0.004 lux minimum illumination in B&W mode and a 132 dB maximum dynamic range. Neither camera has a low-light advantage over the other based on the provided specifications.
Can the S65501-Z1 be used indoors, or is it overkill for an interior lobby?
The S65501-Z1 is fully functional indoors, but its IP66/IK10 enclosure, larger ø165mm footprint, and higher power consumption (up to 18.9W on PoE+) add cost without benefit in a controlled interior environment. The S61501-Z1 is purpose-built for indoor use at a smaller size and lower power draw, making it the more appropriate choice for lobbies and similar spaces.
Does the S65501-Z1 pan faster than the S61501-Z1?
Yes. The S65501-Z1 reaches 500°/s preset pan speed when powered via PoE+, versus 350°/s for the S61501-Z1. Manual panning speed is identical on both at 0.065–150°/s. The faster preset recall on the S65501-Z1 is only available at its full PoE+ power draw of 18.9W.
