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.

Vivotek IP6112, IP6122 manual Video Codec Parameters

IP6122, IP6112 specifications

The Vivotek IP6112 and IP6122 are two advanced network cameras that cater to a wide range of surveillance needs. Both models are designed to deliver high-quality video surveillance solutions suitable for various applications, including retail stores, offices, and residential settings.

The Vivotek IP6112 boasts a 1-megapixel resolution, providing clear and detailed images with a maximum frame rate of 30 frames per second. This camera also features a built-in IR-cut filter, which ensures excellent color reproduction during the day and optimal performance at night. Its IR LEDs allow for night vision capabilities, enabling visibility up to 15 meters in complete darkness. This feature is essential for round-the-clock monitoring, ensuring critical areas remain visible regardless of the time.

On the other hand, the Vivotek IP6122 elevates the specifications with a 2-megapixel resolution, delivering even sharper imagery. This model supports HD video quality, making it ideal for situations where detail is paramount. The IP6122 not only enhances image clarity but also includes WDR (Wide Dynamic Range) technology. This innovative feature enables the camera to manage complex lighting scenarios, maintaining clarity in environments with significant contrasts between bright and dark areas.

Both IP cameras leverage H.264 compression technology, which significantly reduces file sizes without compromising on video quality. This technology is essential for efficient bandwidth usage and storage, allowing users to store vast amounts of footage without requiring extensive network resources.

In terms of installation flexibility, both models are equipped with Power over Ethernet (PoE) support. This feature simplifies installation by allowing the camera to receive power and data over a single cable, reducing clutter and increasing convenience. Additionally, both devices offer a variety of mounting options, making it easy to tailor the installation to specific surveillance needs.

Vivotek’s built-in Web server enables straightforward access to the camera’s features via a web browser, allowing users to configure, monitor, and manage their security system with ease. Furthermore, both models support multiple streaming capabilities, enabling simultaneous viewing and recording of high-resolution video to various devices.

In summary, the Vivotek IP6112 and IP6122 cameras offer a compelling blend of high resolution, advanced technology, and user-friendly features, making them suitable choices for anyone looking to enhance their security infrastructure. With options catering to both basic and more demanding surveillance requirements, these models stand out in the market for IP cameras.
