Extra Info
Smart Codec (H.265+/H.264+)
This advanced video compression technology optimizes bandwidth and storage efficiency by reducing file sizes without compromising video quality. Ideal for surveillance systems with multiple high-resolution cameras or setups that rely on limited storage space, Smart Codec ensures smoother performance and longer retention times for recorded footage. It is especially beneficial in 24/7 monitoring applications where storage and network resources are at a premium.
Smart IR – Up to 30 Meters
Equipped with intelligent infrared technology, the camera automatically adjusts IR intensity based on object proximity. This prevents overexposure of close objects during nighttime surveillance, maintaining image clarity and detail even in pitch-black environments. With effective illumination up to 30 meters, it ensures reliable coverage for driveways, perimeters, and building exteriors.
Tripwire & Intrusion Detection
These built-in IVS (Intelligent Video System) features enhance perimeter security by generating real-time alerts when predefined lines are crossed or movements are detected within restricted zones. Perfect for securing entry points, fences, and critical areas, these functions reduce the need for constant manual monitoring and enable quick response to potential threats.
Weatherproof & Vandal-Proof Design
Engineered for durability, the camera boasts an IP67-rated enclosure that protects against dust, rain, and harsh weather conditions. Additionally, its IK10-rated vandal-resistant housing safeguards the camera from physical impact and tampering, making it suitable for installation in exposed or high-risk areas such as public spaces, parking structures, or commercial perimeters.
Wide Dynamic Range (WDR)
WDR technology enhances image clarity by balancing lighting in high-contrast scenes. It simultaneously captures both the bright and dark areas of a scene, making it ideal for environments with challenging lighting conditions — such as building entrances, storefronts with large windows, or parking lots — where both shadowed and brightly lit areas must be clearly visible.
