Structural Characteristics

1. Compact mini-dome integrated structure, all-in-one lens, IR LED, processing circuit and network interface sealed inside single enclosure
2. Multi-point EPDM full surrounding sealing design, prevents rainwater, dust and insect intrusion for outdoor deployment
3. Internal aluminum alloy passive heat sink without cooling fan, zero mechanical failure risk
4. Hidden PoE Ethernet cable rear inlet, cable gland with waterproof compression seal nut
5. Rotatable mounting base allows 360° horizontal camera angle adjustment during installation
6. Built-in Edge Vault hardware cybersecurity encryption module to prevent firmware tampering and network hacking

Working Principle

1. Fisheye 182° wide-angle lens captures full surrounding scene light signal onto CMOS image sensor.
2. ARTPEC-8 SoC chip executes real-time digital dewarp algorithm to correct fisheye barrel distortion, generating multiple split-view monitor streams simultaneously.
3. DLPU deep learning unit runs embedded intelligent video analysis algorithms: motion detection, object classification, loitering alert, cross-line detection without external server computing.
4. Lightfinder sensor gain adjustment automatically boosts image brightness under ultra-low light conditions; auto IR-cut filter switches color/monochrome mode at dusk.
5. H.265 Zipstream compression reduces video bandwidth and storage space by up to 50% while retaining forensic image detail, video stream transmitted via PoE Ethernet to NVR or monitoring client.

Installation Requirements

1. Ceiling/wall mounting compatible with standard Axis T94 series mounting brackets; use stainless steel expansion bolts for outdoor concrete wall installation
2. Maintain minimum 0.5 m clearance around camera dome to avoid lens occlusion by obstacles
3. PoE power supply switch IEEE 802.3af compliant; CAT5e/CAT6 shielded Ethernet cable required for outdoor long-distance wiring
4. Cable inlet gland fully tightened with rubber seal to prevent rainwater capillary penetration into camera enclosure
5. Mount camera dome facing downwards; avoid direct overhead sunlight long-term exposure to prevent lens overheating
6. Install lightning surge protection device at Ethernet cable entry point for open-area outdoor deployment

Function & Feature Highlights

1. Single camera full 360° panoramic monitoring, eliminates blind spot dead zones, reduces total camera quantity investment
2. Embedded DLPU AI processing, runs multiple intelligent video analytics locally without extra server hardware
3. IK10 highest-grade anti-vandal protection, resistant to heavy impact from stones, metal tools
4. IP66 all-weather outdoor rating, stable operation under heavy rain, snow, dust, wide temperature fluctuation
5. Forensic WDR wide dynamic range balances bright sunlight and shadow dark area image detail simultaneously
6. Zipstream intelligent encoding drastically lowers network bandwidth and video recording storage consumption
7. Edge Vault hardware encryption secures camera firmware, video data and user access credentials against cyber attack
8. Zero-fan passive cooling design, no fan noise or dust clogging failure risk for long-term 24/7 operation

Typical Application Scenarios

• Commercial shopping mall open atrium full-surround monitoring
• Factory outdoor yard, logistics warehouse loading zone panoramic surveillance
• Public parking lot, underground garage blind-spot elimination monitoring
• School campus playground, hospital outdoor public area security camera
• Railway station, bus station passenger flow full-view monitoring
• Industrial factory workshop large open production area single-point full coverage

Operation & Maintenance Precautions

1. Cut PoE power supply before removing camera dome cover for lens cleaning or parameter reset
2. Clean transparent dome bubble only with neutral glass cleaner and soft microfiber cloth; corrosive chemical cleaners crack polycarbonate surface
3. Quarterly inspect cable gland sealing condition; replace aging cracked rubber gaskets to maintain IP66 waterproof performance
4. Avoid painting directly onto camera housing or dome bubble, paint blocks lens light transmission
5. Prevent tree branches or signage growing within camera field of view after long-term deployment
6. Annual check mounting bolt tightness; thermal expansion cycles loosen fasteners over seasons
7. Do not expose camera to high-pressure power washing jet directly, water penetrates sealing gaps under high pressure
