■ 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, 4Mbps, 6Mbps, and 8Mbps� 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

You can set up different video resolution for different viewing devices� For example, set a smaller frame size and lower bit rate for remote viewing on mobile phones and a larger video size and a higher bit rate for live viewing on web browsers� Note that a larger frame size takes up more bandwidth�

■ Maximum frame rate

This limits the maximum refresh frame rate per second� Set the frame rate higher for 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� The frame rate will decrease if you select a higher resolution�

■ Video quality

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�

NOTE

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

►Converting high-quality video may significantly increase the CPU loading, and you may encounter streaming disconnection or video loss while capturing a complicated scene� In the event of occurance, we suggest you customize a lower video resolution or reduce the frame rate to obtain smooth video�

FD8361L specifications

The Vivotek FD8361L is a sophisticated network camera designed specifically for outdoor surveillance and monitoring applications. It is part of the FD series, which is renowned for its reliability and high-performance features. The FD8361L boasts a robust and elegant design, making it suitable for various environments while providing excellent video quality and performance.

One of the standout features of the FD8361L is its 2-megapixel resolution, which delivers high-definition images and ensures clear and detailed video capture. This camera can record at a frame rate of up to 30 frames per second (fps) at 1080p, suitable for fast-moving objects and dynamic scenes. This high-performance video capture is crucial for security applications, allowing for accurate identification and monitoring.

The camera is equipped with WDR Pro (Wide Dynamic Range) technology, enabling it to perform well in challenging lighting conditions. This feature helps to balance the exposure levels in environments where both bright and dark areas are present, ensuring clear visibility without overexposed highlights or underexposed shadows.

Another significant characteristic of the FD8361L is its Infrared (IR) functionality, which provides night vision capabilities. With built-in IR LEDs, the camera can capture clear images even in total darkness, reaching distances of up to 30 meters. This ensures 24/7 surveillance, making it ideal for areas requiring constant monitoring.

In terms of durability, the FD8361L is constructed with an IP66-rated housing, making it weatherproof and resistant to harsh environmental conditions such as rain, wind, and dust. Additionally, it is equipped with a robust metal casing that provides extra protection against vandalism, making it suitable for outdoor installations in high-risk areas.

The FD8361L also supports Power over Ethernet (PoE) technology, allowing for simpler installation by enabling power and data transmission through a single cable. This feature reduces the need for additional power sources, streamlining setup and operation.

With advanced features like smart stream technology, which optimizes bandwidth usage by adjusting the quality of streaming video, this camera ensures efficient data transmission without compromising image quality. Furthermore, it supports various video compression formats, including H.264 and MJPEG, allowing for flexibility in network and storage configurations.

Overall, the Vivotek FD8361L is a versatile and high-performing network camera influenced by contemporary surveillance needs, providing significant contributions to security and monitoring in diverse applications. Its combination of excellent image quality, advanced technologies, and durable design makes it an excellent choice for both residential and commercial surveillance solutions.
