Its advanced imaging technology ensures sharp visuals even in challenging lighting conditions, while integrated audio support allows for real-time monitoring. The camera's durable design is built to withstand harsh outdoor environments, making it ideal for both residential and commercial use.

Description:

This network camera combines high-resolution 2MP video capture with wide dynamic range (WDR) for enhanced detail in varying light. Equipped with a 4mm lens and M12 lens mount, it provides crisp 1920x1080 footage, while its Smart Hybrid Light extends visibility up to 30 meters using both IR and white light. The built-in microphone allows for mono audio recording, supporting real-time audio security. Advanced compression with H.265+ reduces bandwidth and storage requirements, and multiple digital enhancements like BLC, HLC, and 3D DNR improve image quality. With motion detection and up to 6 simultaneous live views, it provides comprehensive monitoring from a single device. The camera connects via a 10M/100M RJ45 self-adaptive Ethernet port and is rated IP67 for resistance to water and dust, making it suitable for outdoor surveillance applications.

Features:

High-Resolution Video Capture
Delivering 2MP resolution, the camera ensures clear images and smooth video streaming. WDR technology balances exposure in high-contrast scenes, capturing details in shadows and highlights simultaneously.

Advanced Lighting Technology
The Smart Hybrid Light feature combines infrared and white light to illuminate up to 30 meters, maintaining image clarity in low-light conditions. It adapts automatically for optimal brightness without overexposure.

Integrated Audio Monitoring
A built-in microphone enables mono sound recording, allowing users to monitor audio alongside video. This provides an extra layer of security for real-time observation.

Digital Image Enhancement
Digital enhancements include backlight compensation (BLC), high light compensation (HLC), and 3D digital noise reduction (DNR), all working together to deliver clear and stable images even in challenging conditions.

Connectivity and Storage Optimization
The camera uses H.265+, H.265, H.264+, and H.264 compression formats to minimize storage use and reduce network bandwidth. Its RJ45 10M/100M self-adaptive Ethernet port ensures seamless integration into existing network setups.

Outdoor Durability
IP67-rated design provides protection against dust and water, making it ideal for outdoor surveillance applications, from building perimeters to open parking areas.

Smart Monitoring Tools
Motion detection and 1 fixed region of interest (ROI) allow for focused surveillance, with support for up to 6 simultaneous live view channels for comprehensive coverage.
