Setup

5-4. Record Setup

This is the most important configuration of the DVR. Enter into SYSTEM MENU-RECORD SETUP and press the [ENTER] button.

5.4.1 Record Configuration

Use direction button to move and [-] [+] button to set value.

1.OVERWRITE: Set overwrite or stop recording when the HDD is full.

2.MULTIPLEX: DUPLEX: Playback & Ethernet

TRIPLEX: Playback & Recording & Ethernet

Note: DUPLEX MODE is recommended to playback the images at a maximum frame rate. But, one down side is that it causes the DVR not to record during a playback/search.

3.QUALITY: Setting recorded picture quality.

To select the picture quality, the user will step-through the quality settings as listed below. Be aware the higher the resolution (eg: Super Fine), the quicker the HDD capacity will be used up and images will be overwritten earlier. For most operations we recommend either BASIC or NORMAL.

BASIC ->NORMAL ->ENHANCED ->FINE ->SUPER FINE: Default quality set by manufacturer is Super Fine

In Emergency recording mode, recording quality is SUPER FINE.

To send more images via IP network and longer recording time, set QUALITY at NORNAL or ENHANCED and record at 360x240 or 360x120.

Data size of image in PAL system is a little bigger than NTSC system, but the total recording time is same as in NTSC system.

JPEG 2000 specifications

Stinger JPEG 2000 is a powerful image compression technology that offers advanced solutions for high-quality image storage and transmission. Utilizing the principles of wavelet transformation, JPEG 2000 provides significant benefits over the traditional JPEG format, particularly in terms of image quality, compression efficiency, and flexibility.

One of the main features of Stinger JPEG 2000 is its support for lossless and lossy compression modes. This versatility allows users to select the appropriate mode based on their image quality requirements and storage capacities. Lossless compression ensures that no image data is lost during the compression process, making it ideal for applications that require exact reproductions, such as medical imaging and archiving. On the other hand, lossy compression significantly reduces file sizes while maintaining a perceptible level of quality, making it suitable for web images and streaming.

Another notable characteristic of Stinger JPEG 2000 is its ability to handle high-resolution images efficiently. The wavelet-based encoding method enables the preservation of fine details, ensuring that even images with intricate designs remain sharp and clear after compression. This is particularly important in fields like digital cinema, where the highest quality is paramount.

Stinger JPEG 2000 also supports progressive decoding, meaning images can be transmitted and rendered in layers. This feature allows users to view a low-resolution version of an image quickly while the higher-resolution data is still being received. This is especially beneficial for web applications where loading times are critical.

Additionally, Stinger JPEG 2000 includes robust error resilience capabilities. The technology can recover more gracefully from data corruption, making it an excellent choice for streaming applications where data loss can occur. The format's capability to store additional metadata also enhances its functionality, enabling the inclusion of information such as color profiles, image creation data, and other pertinent details that help manage and organize image files.

In summary, Stinger JPEG 2000 revolutionizes the way images are compressed, offering advanced features such as lossless and lossy options, efficient handling of high-resolution images, progressive decoding, and enhanced error resilience. These characteristics make it a preferred choice for professional applications where image quality and reliability are critical, paving the way for a broader adoption in various industries, including media, healthcare, and digital archiving.
