Vivotek Vortex IB839 EHT 1Y 5MP Outdoor Varifocal IR Bullet IP Camera

Vivotek IB839-EHT-1Y 5MP Outdoor Varifocal IR Bullet Camera

The Vivotek Vortex IB839 EHT 1Y is a professional-grade 5MP outdoor bullet IP camera engineered for demanding surveillance applications. This compact yet powerful camera combines high-resolution imaging with advanced analytics capabilities, delivering reliable performance across diverse outdoor environments. The motorized varifocal lens and integrated IR illumination make it ideal for perimeter security, parking facilities, and critical infrastructure monitoring where flexibility and low-light performance are essential.

Key Features

• 5 Megapixel 1/2.7" Progressive CMOS sensor with 2560 x 1920 HD resolution
• Motorized varifocal lens (2.8–10mm) with remote focus capability
• Horizontal field of view: 95°–41° for adaptable deployment
• 30-meter IR illumination for complete darkness surveillance
• Extreme low-light sensitivity: 0.06 lux color, 0.01 lux B/W
• Robust IK10-rated metal housing for outdoor durability
• PoE power delivery simplifies installation
• Built-in 256GB industrial microSD card for onboard recording
• Secure firmware with HTTPS/TLS encryption and video protection

Technical Highlights

The camera operates at 15 fps in HD mode, with efficient H.265-style compression delivering HD video at just 1.2 Mbps upload bandwidth. Its fixed iris and f1.8 maximum aperture ensure optimal light gathering in low-illumination conditions. Day/night operation with automatic IR cut filter switching maintains image quality across 24-hour cycles. The shutter speed range of 1/5 to 1/32,000 seconds provides precise exposure control in challenging lighting scenarios.

Advanced connectivity includes support for RTSP, WebRTC, HTTPS, IPv4/IPv6, and network security protocols (TLS 1.2, SSL). The camera accommodates up to 6 simultaneous client connections with flexible viewing options. IEEE 802.3af PoE Class 0 operation consumes a maximum of 12.95W with IR active, making it compatible with standard network infrastructure.

Intelligent Analytics

Built-in people and vehicle analytics include intrusion detection, line-crossing detection, and loitering alerts. Object detection capabilities encompass unattended and missing object monitoring. Scene search functionality supports efficient footage navigation. Tampering detection alerts administrators to camera obstruction or intentional interference, enhancing security posture.

Applications

Ideal for perimeter protection, parking lot surveillance, building entry points, transportation hubs, and public spaces. The flexible varifocal lens suits installations requiring both wide situational awareness and targeted zoom monitoring. Operating temperature range (-13°F to 140°F) and 98% RH tolerance ensure reliable performance in harsh outdoor conditions.

Certifications & Warranty

EMC certified (CE, FCC, RCM, VCCI), safety-rated (UL, CB), and environmentally rated (IK10). Backed by a 10-year warranty, reflecting Vivotek's confidence in product durability.

James Everett

The IB839 EHT 1Y positions itself as a mid-range outdoor solution balancing resolution, optical flexibility, and analytics depth. The motorized varifocal design eliminates the need for camera repositioning, reducing installation labor and downtime. IR performance at 30 meters is respectable for perimeter duty, though operators should account for IR reflectance from building materials when planning coverage.

The fixed iris may challenge extreme backlighting scenarios, but the sensor's dynamic shutter range mitigates this concern. Built-in analytics reduce reliance on external VMS servers for basic detection tasks, lowering total system cost. The 256GB onboard storage provides approximately 50+ hours of HD recording (at 1.2 Mbps), suitable for temporary buffering between network outages.

For installations requiring extended recording and high-density deployments, a robust NVR platform remains recommended to leverage the camera's full detection capabilities.
