i-PRO S1536LA vs i-PRO X15300-V3L: Specification Comparison
Both the i-PRO WV-S1536LA and WV-X15300-V3L are 2MP outdoor fixed bullet IP cameras sharing the same 1/2.8-type CMOS sensor, 3.1× motorized varifocal lens, and 70m IR range. They are genuine cross-shop candidates for perimeter and general-purpose outdoor surveillance where the buyer is deciding between a standard PoE platform and a PoE+ platform with added hardware features such as gyro-based image stabilization, secure boot, and a newer SoC.

How do the imaging specs compare?
Both cameras share the same 1/2.8-type CMOS sensor with a 5.57 mm × 3.13 mm scanning area, identical minimum color illumination of 0.007 lx at 30IRE, and identical minimum B&W illumination of 0.005 lx. Both offer a 2.9–9 mm motorized varifocal lens with 3.1× optical zoom, an extra digital zoom up to 9.3× at 640×360 resolution, maximum aperture of F1.3 at wide, 60fps at 1920×1080, and a maximum 144 dB dynamic range via Super Dynamic level 31. IR illumination is rated at 70m (30IRE) on both units. DORI distances are identical across all four tiers on both models.
The X15300-V3L distinguishes itself with a newer Ambarella CV52 SoC versus the S1536LA's Ambarella CV25M. The X15300-V3L also specifies a gyro-based image stabilizer (On/Off), which the S1536LA does not list. The X15300-V3L's B&W minimum illumination spec explicitly states 0 lux with IR active; the S1536LA's spec does not include that 0-lux qualifier. The S1536LA specifies Fog Compensation with manual contrast adjustment; the X15300-V3L specifies Fog Compensation with a 0–8 range. Both cameras support H.265, H.264, and MJPEG compression with CBR/VBR and Variable GOP.
What about installation and environment?
Both cameras share identical physical dimensions (133 mm W × 133 mm H × 383 mm D), identical IK10 impact resistance, IP66 water and dust ingress protection, NEMA 4X compliance, and wind resistance up to 40 m/s. Ceiling and wall mounting angular ranges are identical on both. The S1536LA weighs approximately 2.4 kg versus the X15300-V3L's 2.5 kg.
The operating temperature ranges differ: the S1536LA is rated –40°C to +60°C (power-on from –30°C), while the X15300-V3L is rated –40°C to +55°C (power-on from –30°C). The S1536LA therefore supports a 5°C higher upper operating temperature. The X15300-V3L additionally carries an IP67 rating (the S1536LA lists IP66 only). On power, the S1536LA operates on DC 12V or PoE 802.3af (9.1W, PoE Class 0), whereas the X15300-V3L requires DC 12V or PoE+ 802.3at (14W, PoE Class 4), demanding a PoE+ capable switch or injector. The S1536LA includes an anti-condensation system (Temish element, heater, and moisture absorption gel); no equivalent spec is listed for the X15300-V3L.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, S, T, and M and up to 14 simultaneous users. Both support microSD/SDHC/SDXC edge storage up to 512 GB. Both include FIPS 140-2 Level 3 security, HTTPS, device certificate, and IEEE 802.1X. The X15300-V3L explicitly lists secure boot and signed firmware as separate spec entries; the S1536LA lists signed firmware in its product attributes but does not list secure boot as a separate spec. Both support G.726, G.711, and AAC-LC audio compression, full-duplex audio, and a 3.5mm stereo mini-jack input and output.
Both cameras include the same AI sound classification set (gunshot, yell, vehicle horn, glass break), VMD with 4 areas, scene change detection, and up to 8 privacy zones. The S1536LA's IPv6 protocol list includes SFTP, FTP, SMTP, MLD, LLDP, and SNMPv1/v2/v3 explicitly; the X15300-V3L's IPv6 list is more abbreviated in the provided spec (TCP/IP, UDP, HTTP, HTTPS, MQTT, SNMP, DNS, NTP). The S1536LA lists a VBS 1.0V composite monitor output for adjustment; no equivalent is listed for the X15300-V3L. The S1536LA's audio input spec lists plug-in power mic support and input impedance of 2 kΩ at –10 dBV; the X15300-V3L's audio input spec does not list those parameters.
Which should you choose: the S1536LA or the X15300-V3L?
Our take: The X15300-V3L is the stronger choice when the installation environment demands gyro-based image stabilization, a newer Ambarella CV52 SoC, an explicit IP67 immersion rating, or secure boot capability. Concretely: the X15300-V3L adds gyro image stabilization (not present on the S1536LA), an IP67 ingress rating versus the S1536LA's IP66, and a PoE Class 4 (802.3at, 14W) power budget versus the S1536LA's PoE Class 0 (802.3af, 9.1W). The S1536LA is the better fit when the existing network infrastructure is limited to 802.3af PoE switches, when the installation site operates above 55°C (the S1536LA is rated to +60°C versus the X15300-V3L's +55°C), or when an anti-condensation system is required, as only the S1536LA specifies a Temish element, heater, and moisture absorption gel. Both are identical on resolution, sensor, lens, IR range, and DORI performance.

Frequently Asked Questions
Which should you choose: the S1536LA or the X15300-V3L?
The X15300-V3L is the stronger choice when the installation environment demands gyro-based image stabilization, a newer Ambarella CV52 SoC, an explicit IP67 immersion rating, or secure boot capability. Concretely: the X15300-V3L adds gyro image stabilization (not present on the S1536LA), an IP67 ingress rating versus the S1536LA's IP66, and a PoE Class 4 (802.3at, 14W) power budget versus the S1536LA's PoE Class 0 (802.3af, 9.1W). The S1536LA is the better fit when the existing network infrastructure is limited to 802.3af PoE switches, when the installation site operates above 55°C (the S1536LA is rated to +60°C versus the X15300-V3L's +55°C), or when an anti-condensation system is required, as only the S1536LA specifies a Temish element, heater, and moisture absorption gel. Both are identical on resolution, sensor, lens, IR range, and DORI performance.
Is the S1536LA or X15300-V3L better for low-light performance?
Both cameras share the same minimum color illumination of 0.007 lx at 30IRE and B&W illumination of 0.005 lx. The X15300-V3L additionally specifies 0 lux operation when IR is active; the S1536LA's spec does not include that 0-lux qualifier. IR illumination distance is rated at 70m on both. Neither camera is specified as superior in color sensitivity based on the provided specs.
Do I need a PoE+ switch to use the X15300-V3L?
Yes. The X15300-V3L is rated at 14W and is classified as PoE Class 4, which requires 802.3at (PoE+) infrastructure. The S1536LA draws 9.1W and is PoE Class 0, compatible with standard 802.3af switches. If your existing switch plant is 802.3af only, the S1536LA is the compatible choice without switch upgrades.
Which camera is better suited for high-temperature outdoor enclosures?
The S1536LA is rated for ambient operation up to +60°C, compared to the X15300-V3L's +55°C upper limit. In environments where enclosure or ambient temperatures can approach or exceed 55°C — such as rooftop or desert installations — the S1536LA's +60°C rating provides a 5°C additional margin per the provided specifications.
