■ Intra frame period

Determine how often to plant an I frame. The shorter the duration, the more likely you will get better video quality, but at the cost of higher network bandwidth consumption. Select the intra frame period from the following durations: 1/4 second, 1/2 second, 1 second, 2 seconds, 3 seconds, and 4 seconds.

■ Video quality

A complex scene generally produces a larger file size, meaning that higher bandwidth will be needed for data transmission. Therefore, if Constant bit rate is selected, the bandwidth utilization is fixed at a selected level, resulting in mutable video quality performance. The bit rates are selectable at the following rates: 20Kbps, 30Kbps, 40Kbps, 50Kbps, 64Kbps, 128Kbps, 256Kbps, 512Kbps, 768Kbps, 1Mbps, 2Mbps, 3Mbps, and 4Mbps. You can also select Customize and manually enter a value.

On the other hand, if Fixed quality is selected, all frames are transmitted with the same quality; bandwidth utilization is therefore unpredictable. The video quality can be adjusted to the following settings: Medium, Standard, Good, Detailed, and Excellent. You can also select Customize and manually enter a value.

If JPEG mode is selected, the Network Camera continuously sends JPEG images to the client, producing a moving effect similar to a filmstrip. Every single JPEG image transmitted guarantees the same image quality, which in turn comes at the expense of variable bandwidth usage. Because the media contents are a combination of JPEG images, no audio data is transmitted to the client. There are three parameters provided in MJPEG mode to control the video performance:

■Frame size

Select the video size. Note that a larger frame size takes up more bandwidth. The frame sizes are selectable in the following resolutions: 176 x 144, 360 x 240, 640 x 480, 800 x 600, and 1280 x 1024.

■Maximum frame rate

This limits the maximal refresh frame rate per second. Set the frame rate higher for a smoother video quality.

If the power line frequency is set to 50Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps and 25fps. If the power line frequency is set to 60Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps, and 30fps. You can also select Customize and manually enter a value.

■ Video quality

The video qualities are selectable at the following settings: Medium, Standard, Good, Detailed, and Excellent. You can also select Customize and manually enter a value.

NOTE

►The Maximum frame rate for 800 x 600 and 1280 x 1024 is limited to 8fps.

►Video quality and fixed quality refers to the compression rate, so a lower will produce higher quality.

IP7138, IP7139 specifications

Vivotek has made its mark in the field of network cameras with the launch of its IP7139 and IP7138 models, which cater to the increasing demand for high-quality surveillance cameras. These two models offer a range of features and advanced technologies that make them suitable for a variety of applications, including home security, commercial monitoring, and even industrial environments.

The Vivotek IP7139 is equipped with a 1/4" CMOS sensor that provides a resolution of 1280x1024 pixels, enabling clear and sharp images. Its ability to capture video at 30 frames per second ensures smooth recordings, which is crucial for monitoring fast-moving objects or individuals. The camera also boasts a built-in infrared filter and infrared LED illumination, allowing for exceptional performance in low-light conditions. This functionality ensures that surveillance can continue around the clock, providing peace of mind at all hours.

On the other hand, the IP7138 model offers similar high-quality imaging capabilities with a slightly different focus. It also utilizes a 1/4" CMOS sensor and supports video resolutions up to 1280x1024 pixels. However, the IP7138 is designed more for indoor applications, making it an ideal choice for small businesses or residential settings. Its compact design ensures it can seamlessly blend into a variety of environments.

Both models feature Vivotek's Smart Stream technology, which optimizes bandwidth usage by efficiently managing data streams. This feature is particularly beneficial in scenarios where network resources are limited, as it allows for the efficient transmission of critical video data while minimizing unnecessary load.

In terms of installation and usability, both the IP7139 and IP7138 are remarkably user-friendly. They support Power over Ethernet (PoE) technology, which simplifies the installation process by enabling power and data to be transmitted over a single Ethernet cable. This streamlines installation and reduces the need for additional cabling.

Further enhancing their adaptability, the cameras come equipped with a built-in web server, allowing users to manage settings and access video feeds remotely via a web browser. Additionally, the IP7139 and IP7138 support various cloud services, making it easier for users to store and access recordings from anywhere.

In conclusion, Vivotek's IP7139 and IP7138 network cameras are packed with advanced features and technologies designed to meet the diverse needs of surveillance users. With high resolution, low-light performance, bandwidth optimization, and ease of installation, these models stand out as reliable choices in the competitive landscape of IP cameras.
