Axis Q1961-TE Thermal Outdoor Fixed IP Camera - 02173-001

We've deployed the Q1961-TE thermal camera across a range of perimeter scenarios — fence lines, warehouse loading docks, parking lots, and outdoor utility yards — and the 02173-001 pendant cable is the enabling accessory that justifies the thermal investment. The critical difference between thermal and visible-light surveillance is that thermal doesn't care about darkness, fog, or rain; a person crossing a fence or climbing a wall shows up as a distinct heat signature at 40 mK sensitivity, even in complete night or heavy weather. But that thermal advantage only works if you can position the sensor at the right vantage point. The pendant mount solves the positioning problem — it lets you hang the camera at an overhang or pole top where the thermal field of view covers the target zone without interfering with structural or electrical infrastructure. The 1.3-meter cable length is no accident; it covers standard soffit overhangs (18–24 inches) and allows the thermal sensor to sit proud of the mounting surface, eliminating radiant heat reflections from the structure itself. We've also found that keeping the camera suspended by cable rather than bolted to metal reduces vibration noise in the thermal imagery — important for analytics that key on small motion signatures.

Technical Highlights:

• Low Power Budget (4.3W via 802.3af): This is a major operational advantage on larger thermal deployments. A single PoE switch port can power 20–30 Q1961-TE cameras without exhausting switch power capacity. On a 32-port PoE switch with 370W total budget, you can run nearly the full complement of thermal cameras without adding a second switch. Contrast that with higher-power PTZ or IR dome cameras, and the per-camera cost of power infrastructure drops measurably.
• IP66 Cable Assembly: The gasket and jacket are verified for hose-down, salt spray, and UV exposure. We spec the 02173-001 with confidence in carwashes, chemical plants, and coastal facilities where water ingress and corrosion are constant threats. Termination quality matters — don't skimp on field connectors if you splice the cable; use sealed RJ45 boots rated for outdoor use.
• Probe-Dependent Mounting Alignment: The pendant probe threads directly into the Q1961-TE's mounting insert. We've seen integration headaches when installers confuse this with other Axis pendant cables (the 01519 or 01520 variants used on different thermal models). Verify part number against your Q1961-TE datasheet before ordering — no cross-compatibility.
• H.264 Thermal Bitstream Over Single RJ45: The cable passes full 8.3 fps H.264 video plus alarm I/O (1 input, 1 output) over a single Ethernet pair. No splitters, no auxiliary signaling lines. Clean, simple integration into any ONVIF-compliant VMS (Genetec, Milestone, Avigilon, ExacqVision all support ONVIF Profile S thermal streaming).

Deployment Considerations:

• Cable length is fixed at 1.3 meters. If your mounting overhang is further than 1.3m from the network closet, you'll need to extend via additional Ethernet cable run to the overhang point, then splice the 02173-001 pendant cable at that junction. Use sealed outdoor splice boxes (rated IP67+) for any junction in rain exposure. Alternatively, place a PoE repeater or injector at the distant mounting point — adds cost, but eliminates long cable runs and voltage-drop risk.
• Thermal camera performance is independent of visible light but depends heavily on clear line-of-sight to the target surface. If the thermal sensor is partially obscured by rain, snow, or ice buildup on the lens, sensitivity degrades. The cable jacket doesn't include lens heaters; for subzero climates with persistent ice risk, budget for an optional lens heater jacket or periodic manual cleaning. Most US perimeter sites don't require this, but it's a known constraint in northern tier or high-altitude deployments.
• PoE power is steady 12V DC distributed by the switch. If your switch has power-management features that reduce voltage at night (some industrial switches do this for energy savings), the Q1961-TE may brownout if voltage drops below 9V. Test switch settings in lab before production deployment; most modern enterprise switches maintain steady 12V, but older or cost-optimized models sometimes surprise you.
• Thermal video over H.264 generates 1–2 Mbps bitrate at 8.3 fps (much lower than visible-light 1080p). Network congestion is rarely the bottleneck; storage is. A 7-day rolling buffer for 16 thermal cameras (quad layout) at 2 Mbps each is roughly 240 GB. Price your NVR storage accordingly — thermal deployments are IO-light but capacity-hungry if you retain 14–30 days of history.
• The 02173-001 has no built-in splice or extension capability. If you need to shorten the cable (rare, but it happens), you'll need to re-terminate the RJ45 end or order a shorter pre-made assembly from Axis (lead time 4–6 weeks). Plan cable routing carefully before installation to avoid having excess coiled at the mounting point.

The 02173-001 is the right choice if you're deploying Q1961-TE thermal cameras on a fixed outdoor perimeter where positioning matters and power simplicity is valued. Thermal excels where visible light fails — night, fog, rain — and the pendant mount puts the sensor exactly where it needs to be without sacrificing cable manageability. For integrators and end-user security teams building multi-camera thermal perimeter systems, this cable is the standard path to installation.
