system and 30 fps in a 60Hz system. If your network bandwidth is more than 384Kbps, you can fix the bit rate according to your bandwidth and set the maximum frame rate to 25 fps or 30 fps. If you are shooting fast-moving images, 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 384 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 “Half” in the “Size” option for better images, or “Halfx2” for a larger image view. 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 speed and adjust the frame rate. Start from 30 fps down for best results but not below 15 fps. If the image qualities are not improved, select a lower bandwidth setting.

PT3113, PT3123 specifications

Vivotek PT3123 and PT3113 are advanced indoor PTZ (pan-tilt-zoom) network cameras designed to provide high-quality surveillance and monitoring solutions for various settings, including retail stores, offices, and public spaces. Both models are equipped with innovative features and state-of-the-art technologies that ensure optimal performance and reliability.

One of the standout features of the Vivotek PT3123 and PT3113 is their impressive 2-megapixel resolution, which delivers crystal-clear video quality. This allows for detailed monitoring, making it easier to identify individuals and capture important events. The cameras support a wide range of video codec formats, including H.265 and H.264, facilitating efficient video compression and streaming. This means that users can benefit from reduced bandwidth and storage requirements while maintaining high video quality.

The PTZ functionality enables operators to have complete control over the camera's movements, allowing them to pan 340 degrees horizontally and tilt 120 degrees vertically. This flexibility ensures that every corner of the monitored area is covered, significantly reducing blind spots. Furthermore, the 10x optical zoom provides users with the capability to zoom in on specific details without compromising image quality.

Both models are equipped with IR (infrared) illuminators that allow for night vision capabilities, enabling clear video capture in low-light conditions. This feature is crucial for 24/7 surveillance, ensuring that the cameras remain effective day and night. Additionally, Vivotek's Smart Stream technology optimizes bandwidth usage by prioritizing important areas in the scene, which further enhances efficiency.

In terms of durability and reliability, the PT3123 and PT3113 are designed with a rugged housing that is IP66 rated, making them resistant to harsh environmental conditions such as dust and water. This makes them suitable for indoor installations where varying conditions may occur.

Both models also support various integration options, enhancing their versatility. They are compatible with a wide range of VMS (Video Management Software) platforms, enabling seamless integration into existing security systems. The cameras also support ONVIF (Open Network Video Interface Forum) protocols, allowing for easy interoperability with third-party devices.

In conclusion, Vivotek PT3123 and PT3113 cameras offer advanced surveillance solutions with top-notch features such as high-resolution video, PTZ functionality, night vision capabilities, and robust build quality. These characteristics make them ideal for enhancing security and monitoring in various environments.
