Video Codec Parameters

“Text on video” The text will be displayed in the black bar above the video window with a timestamp. The timestamp is captured from date and time of the Network Camera that is maintained by a built-in real-time clock.

“Color” Select either for color or monochrome video display.

"Size" There are five options for three video sizes. “Half” is the quarter size of “Normal” and “Normal” is the quarter size of “Double”. “Half x 2” has the same video size as “Normal” but of a lesser quality, while consuming less network bandwidth. “Normal x 2” has the same size as “Double” but of a lesser quality.

“Video codec type” It can be either MJPEG or MPEG4. In MJPEG mode, the video frames are independent. In MPEG4 mode, there are I frames and P frames. To decode a P frame need the information of previous frame. MPEG4 consumes much less network bandwidth than MJPEG.

There are five dependent parameters provided for video performance adjustment. "Maximum frame rate" This limits the maximal refresh frame rate, which can be combined with the "Video quality control" to optimize the bandwidth utilization and video quality. If the User wants to fix the bandwidth utilization regardless of the video quality, choose "Fix bit rate" and select the desired bandwidth. MPEG4 video are composed by I frames and P frames as the following sequence. IPPPPPIPPPPPIPPPP… “Key frame interval” determines how many repeated P frames will appear after one I frame. Large “Key frame interval” can reduce the bit rate, but cause image corrupt longer if there is packet loss while transmission. “Fix bit rate” option and “Key frame interval” option are only available in “MPEG4” mode. The video quality may be poor due to the sending of maximal frame rate within the limited bandwidth when images are moving rapidly. Consequently, to ensure detailed video quality (quantization rate) regardless of the network, it will utilize more bandwidth to send the maximal frames when images change drastically.

"Flip" Vertically rotate the video.

"Mirror" Horizontally rotate the video. Check options both if the Network Camera is installed upside down.

IP6127, IP6117 specifications

Vivotek, a leader in IP surveillance technologies, offers a robust line of network cameras designed for various security needs. Among its notable models are the IP6117 and IP6127, which cater to users seeking high-quality video surveillance in different environments.

The Vivotek IP6117 is a compact and efficient fixed dome network camera designed for indoor applications. It features a 2-megapixel sensor that delivers exceptional image quality with a resolution of 1920x1080 pixels, ensuring that details are captured clearly even in challenging lighting conditions. The camera supports H.264 and MJPEG compression formats, which optimize bandwidth and storage usage while maintaining high video quality. Additionally, the IP6117 is equipped with Wide Dynamic Range (WDR) technology, enabling it to capture details in both bright and dark areas of the scene.

On the other hand, the IP6127 model enhances the feature set with a built-in IR illuminator, making it particularly effective in low-light situations. With its 3-megapixel sensor, the IP6127 can deliver a higher resolution of 2048x1536 pixels, providing even sharper images. This model also utilizes Smart Stream technology, a Vivotek innovation that intelligently manages bandwidth by optimizing video quality based on the importance of the scene, thus allowing for more efficient data usage.

Both cameras excel in flexibility and ease of integration. They support Power over Ethernet (PoE), simplifying installation by eliminating the need for separate power cables. Furthermore, Vivotek's proprietary VAST software enables users to manage multiple cameras easily, with features such as motion detection, alarm notifications, and remote access capabilities.

The build quality of the IP6117 and IP6127 ensures durability, making them suitable for a range of applications, from retail environments to office spaces. With their weather-resistant housing options, these cameras can withstand environmental challenges, making them versatile for both indoor and outdoor surveillance.

In summary, the Vivotek IP6117 and IP6127 network cameras offer a combination of high-resolution imaging, smart compression technologies, and installation flexibility. Their advanced features make them an excellent choice for anyone seeking to enhance their security monitoring systems with reliable and high-performance IP surveillance solutions.
