Hanwha C4950TD vs i-PRO S85402-V2L1: Specification Comparison
Both the Hanwha TNM-C4950TD and i-PRO WV-S85402-V2L1 are outdoor dome IP cameras rated at a combined 8MP output, support PoE+, carry IK10 impact ratings, and target perimeter and general-area surveillance. However, they differ fundamentally in sensor philosophy: the Hanwha pairs an 8MP visible sensor with an uncooled thermal (VGA) imager for bi-spectrum AI analytics, while the i-PRO uses twin 4MP visible CMOS sensors with active IR illumination. Buyers choosing between them are trading thermal detection capability against conventional IR low-light performance.

How do the imaging specs compare?
The Hanwha TNM-C4950TD fields a 1/1.8" CMOS visible sensor at 8MP (30 fps) paired with an uncooled microbolometer thermal sensor at VGA resolution, 12µm pixel pitch, and a specified NETD of <60mK. The visible channel uses a 10.9–29mm motorized varifocal lens (2.6x zoom, F1.7–F1.73) with 120dB WDR (SSDR) and a minimum illumination of 0.06 lux color / 0.005 lux B/W; the thermal channel uses a 13.5mm fixed lens (F1.0) with an angular FOV of H:31.9°/V:24.2°. DORI detection ranges on the thermal channel reach 200.1m wide / 583.4m tele at 25PPM.
The i-PRO WV-S85402-V2L1 deploys two independent 1/2.7" CMOS sensors, each at 4MP (2688×1520), also at 30 fps. Its motorized varifocal lens spans 2.9–7.3mm (2.5x zoom, F2.0–F3.0 wide-to-tele) with 108dB Super Dynamic WDR (level 31) and a minimum illumination of 0.12 lux B/W (50IRE, F2.0, 1/30s). Built-in IR illumination covers 40m (high mode). DORI detection in the visible channel reaches only 45.1m wide / 136.5m tele at 25PPM—substantially shorter than the Hanwha's thermal detection range. The i-PRO offers no thermal sensing; low-light performance depends entirely on IR LEDs and sensor sensitivity.
What about installation and environment?
Both cameras share a -40°C to +60°C operating temperature range and carry IP66, IP67, IK10, and NEMA 4X ratings, making them suitable for the same harsh outdoor environments. The i-PRO adds a wind resistance specification of up to 40 m/s (~89 mph) and an anti-condensation Temish element—neither of which appears in the Hanwha's published specs. The i-PRO also lists UL 62368-1 / c-UL / CE / IEC 62368-1 safety certifications and FCC Part 15 Class A / ICES-003 / EN55032 EMC marks; the Hanwha lists IP66/IP67, IK10, NEMA 4X, and NEMA TS 2 (2.2.8, 2.2.9) but UL/FCC certifications are not listed in the provided spec data.
The Hanwha is substantially larger and heavier: 353.4 × 287.5 × 191.2mm and 4.533kg versus the i-PRO's 250 × 150 × 105mm and approximately 1.8kg. Both are powered by PoE+ (IEEE 802.3at, Class 4). Maximum draw is 23.5W for the Hanwha and 22.2W for the i-PRO—close enough that either works on the same PoE+ switch port. The Hanwha additionally accepts 12VDC. Both use a shielded RJ-45 Gigabit Ethernet interface.
Which fits your VMS and analytics better?
The Hanwha supports ONVIF Profile S/T, Wisenet SUNAPI, and Wisenet Open API, and lists 6 simultaneous unicast streams (up to 3 profiles). Edge storage is dual Micro SD/SDHC/SDXC slots supporting up to 512GB total. Analytics are AI-thermal: fire detection, perimeter breach, temperature anomaly, and vehicle counting—capabilities absent from conventional visible-only cameras. Security is anchored by TPM 2.0 (FIPS 140-2 Level 2), 802.1X (EAP-TLS/LEAP/PEAP), and device certificate pre-installation. RAM is 4GB with 512MB Flash. Audio I/O includes selectable mic/line input (2.5VDC, 2KΩ) and line output (1Vrms max), and 4 configurable I/O alarm ports.
The i-PRO WV-S85402-V2L1 supports ONVIF Profiles G, M, S, and T—adding Profile G (on-camera recording management) and Profile M (metadata/analytics) not confirmed in the Hanwha spec data. It supports up to 24 simultaneous users versus Hanwha's 6. Edge storage is a single microSD/SDHC/SDXC slot (up to 512GB). AI analytics include motion, scene-change detection, audio detection, and AI sound classification (gunshot, yell, vehicle horn, glass break)—plus 6 AI video analytic types; face recognition is listed in summary specs. Security is FIPS 140-2 Level 3 (one level above the Hanwha's Level 2), HTTPS, and 802.1X. Audio connections are three 3.5mm stereo jacks (input) and one 3.5mm stereo output, with 3 alarm I/O terminals.
Which should you choose: the C4950TD or the S85402-V2L1?
Our take: The TNM-C4950TD is the stronger choice when the deployment requires thermal detection—fire, temperature anomaly, or perimeter breach in total darkness or through obscurants—because the i-PRO WV-S85402-V2L1 carries no thermal sensor whatsoever. Concretely: the Hanwha's uncooled microbolometer achieves a DORI detection range of 200.1m (wide) versus the i-PRO's IR-limited 45.1m (wide); its NETD of <60mK enables temperature-anomaly analytics that the i-PRO cannot replicate; and its dual SD slot provides redundant edge storage versus the i-PRO's single slot. Conversely, the i-PRO is the better fit when the priority is FIPS 140-2 Level 3 cybersecurity compliance, ONVIF Profile G/M coverage for on-camera recording management and metadata, support for 24 concurrent VMS streams, or a compact, lightweight form factor (1.8kg vs 4.533kg). Neither replaces the other; the decision pivots on whether thermal detection capability is required.

Frequently Asked Questions
Which should you choose: the C4950TD or the S85402-V2L1?
The TNM-C4950TD is the stronger choice when the deployment requires thermal detection—fire, temperature anomaly, or perimeter breach in total darkness or through obscurants—because the i-PRO WV-S85402-V2L1 carries no thermal sensor whatsoever. Concretely: the Hanwha's uncooled microbolometer achieves a DORI detection range of 200.1m (wide) versus the i-PRO's IR-limited 45.1m (wide); its NETD of <60mK enables temperature-anomaly analytics that the i-PRO cannot replicate; and its dual SD slot provides redundant edge storage versus the i-PRO's single slot. Conversely, the i-PRO is the better fit when the priority is FIPS 140-2 Level 3 cybersecurity compliance, ONVIF Profile G/M coverage for on-camera recording management and metadata, support for 24 concurrent VMS streams, or a compact, lightweight form factor (1.8kg vs 4.533kg). Neither replaces the other; the decision pivots on whether thermal detection capability is required.
Is the TNM-C4950TD or WV-S85402-V2L1 better for complete-darkness low-light surveillance?
They solve darkness differently. The TNM-C4950TD uses its thermal sensor, which requires zero visible light and detects heat signatures at up to 200.1m (wide) regardless of illumination. The WV-S85402-V2L1 uses built-in IR LEDs rated to 40m at high power with a minimum illumination of 0.12 lux B/W. If the detection range exceeds roughly 40m or the scene involves obscurants (smoke, fog), the thermal channel of the Hanwha has a decisive advantage. For short-range IR-lit corridors or parking areas, the i-PRO is a proven, lower-cost approach.
Which camera is easier to mount and install on a standard junction box?
The i-PRO WV-S85402-V2L1 is substantially more compact—250 × 150 × 105mm and approximately 1.8kg—making it compatible with typical pendant or surface-mount junction boxes used for standard dome cameras. The Hanwha TNM-C4950TD is 353.4 × 287.5 × 191.2mm and weighs 4.533kg; its bi-spectrum dual-lens housing requires heavier mounting hardware and more surface area. Plan for a dedicated pole or parapet mount with the Hanwha.
Does either camera meet cybersecurity hardening requirements for government or critical-infrastructure projects?
Both cameras support HTTPS, 802.1X authentication, and hardware-backed security. The i-PRO WV-S85402-V2L1 specifies FIPS 140-2 Level 3 compliance plus signed firmware, which satisfies stricter federal and critical-infrastructure mandates. The Hanwha TNM-C4950TD specifies FIPS 140-2 Level 2 via an onboard TPM 2.0 chip, which meets most commercial and municipal requirements but falls one level below the i-PRO's certification. Verify your project's specific compliance document against each vendor's FIPS certificate before specifying.
