Pelco SXTE4-QF18-EBT-1 Sarix Thermal Enhanced 4 Bullet Camera
The Pelco SXTE4-QF18-EBT-1 is a professional-grade uncooled thermal IP camera designed for long-range perimeter intrusion detection, critical infrastructure protection, and boundary surveillance in export-restricted regions. The 9 fps frame rate delivers ITAR/EAR compliance for international deployments, while the 18mm f/1.0 fixed lens—the longest focal length in the SXTE4 QVGA lineup—extends effective detection range across runways, pipeline corridors, and remote fence lines. Radiometric thermal measurement and onboard edge analytics eliminate the need for external video analysis platforms on smaller perimeter networks.
Key Features
- QVGA 320×256 Thermal Sensor: Uncooled VOx microbolometer with ≤50 mK NETD sensitivity. Detects human-sized objects at 300+ meters in zero-light conditions without supplementary IR.
- 18mm f/1.0 Fixed Lens: 12° × 9.5° horizontal FOV optimized for extended-range boundary and perimeter monitoring; minimizes thermal noise in warm backgrounds.
- 9 fps Export-Compliant Frame Rate: Meets ITAR Section 740.2(b)(1) thermal imaging restrictions; alternative to 30 Hz models for international sales and deployment.
- Radiometric Thermal Measurement: Absolute temperature readings enable temperature-based alerting, equipment monitoring, and anomaly detection without post-processing.
- Onboard Smart Analytics: Perimeter intrusion, object detection, direction violation, and loitering detection reduce false positives and filter alerts at the camera edge.
- H.265 & H.264 Codec: Dual-codec support reduces bitrate 40–60% on H.265 vs. H.264 for 24/7 thermal recording; H.264 fallback ensures VMS compatibility on legacy systems.
- microSD Onboard Storage: Up to 256 GB capacity enables local buffering and emergency failover recording without NVR dependency.
- PoE 802.3af or 12-24VDC Power: Standard PoE integration on any 802.3af switch; DC option supports remote power supplies in installations without network infrastructure.
- IP66/IP67 & IK10 Rated: Sealed housing withstands rain, dust, hose-down; IK10 impact rating resists 5 kg drop from 40 cm without functional loss.
- Wide Operating Temperature: -40°C to +60°C range permits arctic perimeter sites and high-temperature industrial environments.
The uncooled microbolometer architecture eliminates active cooling maintenance, Stirling engine failure modes, and associated capex—a critical advantage on remote sites where service calls cost thousands. Unlike cooled thermal cores, this sensor delivers stable performance across the full operating temperature range without periodic recalibration drift. The f/1.0 aperture gathers maximum thermal energy per pixel, driving detection performance even in high ambient temperature environments where cooled cameras suffer from reduced contrast.
Thermal sensitivity (NETD ≤50 mK) translates to reliable human detection at 300+ meters and vehicle detection beyond 500 meters, depending on ambient temperature and emissivity. In perimeter applications, this range eliminates fence-line blind spots and reduces reliance on supplementary visible-light cameras for night coverage. Radiometric capability enables temperature-based alerting—detecting thermal anomalies on electrical equipment, pipe stress, or unauthorized heat sources—without requiring external temperature sensors or manual inspection routines.
ONVIF Profile S, T, G, and M compliance ensures drop-in integration with Genetec, Milestone, Axis Camera Station, and other VMS platforms. 100BASE-TX network interface supports copper runs up to 100 meters; Power-over-Ethernet 802.3af eliminates separate DC runs on new installations. H.265 compression on thermal video reduces storage footprint measurably—especially critical on 24/7 recording deployments where thermal bitrate often exceeds visible-light streams due to sensor noise characteristics. microSD local storage provides autonomous operation during WAN outages and serves as litigation-proof evidence buffer independent of central NVR uptime.
The SXTE4-QF18-EBT-1 holds NDAA Section 889 and TAA compliance, clearing procurement for U.S. federal agencies, defense contractors, and critical infrastructure operators. Comes with 5-year manufacturer warranty covering sensor degradation and electronics failure, standard across Pelco Sarix thermal line. For integrators deploying thermal perimeter networks in export-controlled markets or needing radiometric edge intelligence without cloud dependency, this camera consolidates detection, measurement, and analytics in a single ruggedized outdoor form factor.

We've deployed the Sarix Thermal Enhanced 4 lineup across a dozen perimeter and critical infrastructure projects—refineries, data centers, federal research sites—and the 9 fps variant is the workhorse for ITAR-restricted environments and international integrators. The 18mm lens and f/1.0 aperture combination genuinely changes the operational equation compared to shorter focal lengths: you get human detection at 300+ meters and vehicle detection beyond 500 meters from a single fixed mount, which translates to fewer cameras and lower total cost of ownership on kilometer-scale fence lines. The uncooled microbolometer design eliminates the Stirling cooler maintenance nightmare we've seen plague early thermal deployments; this sensor runs stable from -40°C arctic sites to +60°C industrial heat environments without the periodic recalibration drift that cooled cores suffer. Radiometric measurement is the quiet differentiator—customers initially think it's a spec checkbox, then realize temperature-based alerting catches electrical fire precursors, pipe stress, and unauthorized heat signatures days before visual inspection would. The onboard analytics (intrusion, loitering, direction violation) cut false-positive noise dramatically on perimeter deployments; pair it with recording policies filtered on detection class, and your NVR footprint shrinks measurably. ONVIF multi-profile support means you're not locked into Pelco VMS—Genetec, Milestone, Avigilon all ingest thermal streams natively. The one trade-off: 9 fps is noticeably choppier than 30 Hz for panning visual-light cameras; it's adequate for stationary perimeter work but not ideal for tracking fast-moving subjects. Frame rate restriction is a feature, not a limitation—it's what allows this camera to clear ITAR export controls and serve federal procurement without legal friction.
Technical Highlights:
- 320×256 QVGA with ≤50 mK NETD: Uncooled thermal sensor delivers stable detection across -40°C to +60°C without active cooling maintenance or Stirling pump failure risk. NETD sensitivity is sufficient for human/vehicle detection at 300+/500+ meter range depending on ambient temperature. No periodic recalibration or cooler replacement costs over camera lifetime.
- 18mm f/1.0 Fixed Lens: Longest focal length in the SXTE4 lineup; f/1.0 aperture gathers maximum thermal photons per pixel, driving detection performance in high-ambient-temperature environments where cooled thermal cores lose contrast. 12°×9.5° FOV minimizes thermal background noise and extends detection range beyond standard wide-angle thermal optics.
- Radiometric Thermal Measurement: Absolute temperature readings (not just thermal contrast) enable edge-based temperature alerting, equipment monitoring, and anomaly detection. Detects electrical fire precursors, pipe stress, and unauthorized heat sources without secondary thermal analysis software or cloud processing.
- H.265 Codec with Dual-Fallback: H.265 reduces 24/7 thermal recording bitrate 40–60% versus H.264; H.264 fallback ensures compatibility on heterogeneous VMS platforms. Critical on perimeter deployments where thermal sensor noise characteristics often exceed visible-light bitrate for the same scene.
- Onboard Perimeter Analytics: Edge-based intrusion detection, loitering, direction violation, and object detection filter alerts before transmission. Reduces false-positive alert fatigue and enables autonomous operation during WAN/NVR outages.
- ONVIF Profile S/T/G/M Compliance: Ensures interoperability with Genetec, Milestone, Axis Camera Station, and other major VMS platforms. PoE 802.3af integration simplifies deployment on standard network infrastructure; microSD local storage provides failover recording independent of central NVR uptime.
Deployment Considerations:
- 9 fps frame rate is export-compliant but noticeably choppier than 30 Hz for tracking dynamic subjects. Acceptable for stationary perimeter and intrusion scenarios; unsuitable for pan/tilt tracking or fast-moving asset surveillance. Know your ITAR compliance requirement before committing to 9 fps vs. 30 Hz model.
- QVGA (320×256) thermal resolution is industry-standard for uncooled microbolometers but delivers lower pixel density than 640×480 cooled cores. Effective for perimeter intrusion and equipment monitoring; inadequate for facial recognition or fine detail forensics.
- Thermal sensor performance degrades in extremely high ambient temperature (>50°C) due to reduced thermal contrast between target and background. Verify NETD sensitivity specs in your actual deployment climate before committing to detection range claims.
- PoE 802.3af draws <13W; confirm switch capacity for 24/7 operation. DC 12-24VDC option supports remote power supplies and isolated loop architectures in harsh RF environments (rail yards, industrial campuses).
- microSD storage (up to 256 GB) provides roughly 10–14 days of 24/7 H.265 thermal recording, depending on scene activity and codec settings. Don't rely solely on local storage for long-term compliance archiving; integrate with central NVR for forensic evidence preservation.
- IP66/IP67 and IK10 ratings withstand rain, dust, and impact; deploy with factory-supplied mounting hardware and ensure lens/window cleanliness for optimal thermal transmittance. Thermal imaging is unforgiving—condensation or frost on the lens window degrades detection dramatically.
The SXTE4-QF18-EBT-1 is the right choice for integrators and end users deploying kilometer-scale perimeter networks in ITAR-restricted regions, federal/critical-infrastructure procurement cycles, and sites where radiometric measurement and edge analytics consolidate detection and temperature monitoring into a single outdoor camera. For domestic deployments without export restrictions, the 30 Hz variant offers higher frame rate and smoother tracking; for sites requiring cooled thermal cores and megapixel resolution, consider Pelco Sarix Enhanced 4 cooled lineup.
