A green bar indicates that even though motions have been detected, the event has not been triggered because the image variations still fall under the defined threshold.

There are two motion detection parameters: Sensitivity and Percentage. In the illustration above, frame A and frame B are two sequential images. Pixel differences between the two frames are detected and highlighted in gray (frame C) and will be compared with the sensitivity setting. Sensitivity is a value that expresses the sensitivity to moving objects. Higher sensitivity settings are expected to detect slight movements while smaller sensitivity settings will neglect them. When the sensitivity is set to 70%, the Network Camera defines the pixels in the purple areas as “alerted pixels” (frame D).

Percentage is a value that expresses the proportion of “alerted pixels” to all pixels in the motion detection window. In this case, 50% of pixels are identified as “alerted pixels”. When the percentage is set to 30%, the motions are judged to exceed the defined threshold; therefore, the motion window will be outlined in red.

For applications that require a high level of security management, it is suggested to use higher sensitivity settings and smaller percentage values.

This ultra-clear resolution is particularly beneficial for environments that require precise surveillance, such as banks, retail stores, and public spaces.

In terms of versatility, the PZ8111 comes equipped with pan and tilt functionalities. This allows for a broader coverage area, meaning fewer cameras are needed to monitor large spaces effectively. The pan range extends up to 355 degrees, while the tilt range covers 90 degrees, enabling users to adjust the camera’s view dynamically. These features ensure that no area is left uncovered, significantly enhancing the overall efficiency of the surveillance system.

The PZ8111 also incorporates advanced day/night capabilities, including infrared illumination. This technology ensures that the camera can capture high-quality footage even in low-light conditions, providing 24/7 security monitoring. The automatic switch between color and black-and-white modes is seamless, allowing for continuous observation without compromising image clarity.

Another significant aspect of the Vivotek PZ8111 is its integration with modern network infrastructure. The camera supports Power over Ethernet (PoE), which simplifies installation by allowing both power and data to be transmitted through a single cable. This feature not only reduces installation costs but also enhances system reliability.

Furthermore, the PZ8111 is equipped with intelligent video analytics features. These tools include motion detection, tampering detection, and even people counting functions. Such capabilities empower users to set specific alerts for unusual activities, ensuring prompt responses in critical situations.

Additionally, the PZ8111 supports various streaming protocols, including RTSP and ONVIF, making it a flexible choice for integration with existing security systems. This compatibility allows for easier management and integration of security hardware, ensuring users get the most out of their investment.

Overall, the Vivotek PZ8111 is a comprehensive surveillance solution that combines high-resolution imaging, versatile pan-and-tilt functionality, advanced night vision, and intelligent analytics. Its innovative features make it an exceptional choice for businesses and homeowners alike, providing peace of mind through reliable and effective security monitoring.
