For Best Real-time Video Images

audio. Due to the limitation of the bandwidth for 3GPP, only 176x144 video solution will be supported for cell phone viewing. Select the “Configure for mobile viewing” option will change the range of other related video settings.

To achieve good real-time visual effect, the network bandwidth should be large enough to allow a transmission rate of greater than 20 image frames per second. If the broadband network is over 1 Mbps, set the “Fix bit rate” to 1000Kbps or 1200Kbps, and set “Fix quality” at the highest quality. The maximum frame rate is 30. If your network bandwidth is more than 512Kbps, you can fix the bit rate according to your bandwidth and set the maximum frame rate to 30 fps. If the images vary dramatically in your environment, you may want to slow the maximum frame rate down to 20 fps in order to lower the rate of data transmission. This allows for better video quality and the human eyes cannot readily detect the differences between those of 20, 25, or 30 frames per second. If your network bandwidth is below 512 Kbps, set the “Fix bit rate” according to your bandwidth and try to get the best performance by fine-tuning with the “Maximum frame rate”. In a slow network, greater frame rate results in blur images. Another work-around is to choose “160x120” in the “Size” option for better images. Video quality performance will vary somewhat due to the number of users viewing on the network; even when the parameters have initially been finely tuned. Performance will also suffer due to poor connectivity because of the network’s burst constraint.

Only Quality Images Will Do

To have the best video quality, you should set “Fix quality” at “Detailed” or “Excellent” and adjust the “Maximum frame rate” to match your network’s bandwidth. If your network is slow and you receive “broken” pictures, go to the TCP protocol in “Connection type” and choose a more appropriate mode of transmission. The images may suffer a time delay due to a slower connection. The delay will also increase with added number of users.

Somewhere Between Real-time and Clear Images

If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than setting “Fix bit rate”. You can also fix the bandwidth according to your actual network

IP71353ISMA, IP71353 specifications

The Vivotek IP71353 and IP71353ISMA are advanced network cameras designed to provide comprehensive surveillance solutions for both indoor and outdoor applications. These two models are particularly praised for their robust feature set and reliable performance, making them ideal choices for various security needs.

One of the standout features of the Vivotek IP71353 is its high-resolution video capture capability. With a maximum resolution of 1280 x 800 pixels, this camera delivers sharp and detailed images, allowing users to monitor critical areas effectively. The IP71353ISMA variant offers similar specs while incorporating additional enhancements suited for specific monitoring requirements.

Both models utilize H.264 compression technology, which significantly reduces bandwidth and storage requirements without compromising on video quality. This is particularly beneficial for users looking to maintain long-term recordings without overwhelming their network capacity or storage devices.

An important aspect of the Vivotek IP71353 series is its versatility in installation. The cameras come with a compact design, enabling easy mounting in various locations, whether on walls, ceilings, or other fixtures. Their weather-resistant housing makes them suitable for outdoor use, ensuring durability against the elements.

Additionally, Vivotek has equipped these cameras with infrared (IR) night vision capabilities, allowing users to capture clear images in low-light conditions. The effective range of the IR illumination can extend up to 15 meters, ensuring that surveillance continues seamlessly around the clock.

The IP71353 and IP71353ISMA also feature a built-in microSD/SDHC card slot, providing local storage options for recorded footage. This is particularly useful for users looking for added redundancy or who may face network interruptions.

Another notable characteristic is the support for two-way audio, which facilitates real-time communication through the camera. This feature can be pivotal for applications where interaction is necessary, such as remote monitoring of facilities, enabling guards, or communicating with visitors.

In terms of connectivity, both cameras support Power over Ethernet (PoE), simplifying the installation process by allowing power and data to be delivered through a single cable. This enhances installation flexibility and reduces clutter around the camera.

To summarize, the Vivotek IP71353 and IP71353ISMA provide a comprehensive security solution with high-resolution video, advanced compression technologies, weather-resistant design, night vision capabilities, and flexible installation options. Their combination of features makes them an excellent choice for users seeking reliable and efficient surveillance solutions.
