Setting Jpeg File Size Setting for VN-V25/26

Interpretation Acquire the file size setting of JPEG. If the response is 40k for example, the setting is 40KB. Allowed users admin, operator, user

Setting JPEG File Size Setting for VN-V25/26

Format /api/param?encode(1).quality=Data

Example /api/param?encode(1).quality=30k

Example of response encode(1).quality&202 Accepted(encode(1).status=save)

Interpretation Change the file size setting of JPEG. The unit of set values is in KB. VN-V25/26 will perform rate control with this file size as the target.

When frame size is VGA, setting between the range of 10k to 100k is possible. When frame size is QVGA, setting between the range of 3k to 33k is possible.

When VFS (VariableFileSize) is specified for rate control at the WEB setting page, 7 levels will be available for selection. Each of these choices corresponds to the file sizes as follows.

Level	File Size Setting for VGA	File Size Setting for QVGA
1	80k	27k
2	60k	20k
3	40k	13k
4	30k	10k

5	25k	8k

6	20k	7k
7	15k	5k

When rate control is set to vfs and a file size that is not stated above is specified, the closest choice will be displayed on the WEB setting page. The change is saved by the API, encode(1).status=save. If the change is not saved, the setting is restored by reboot.

VN-V26U, VN-V25U specifications

JVC has made significant strides in the surveillance sector with the introduction of its VN-V25U and VN-V26U series of network cameras. These cameras are designed to deliver high-quality video surveillance solutions for various applications, from commercial establishments to residential settings. Both models offer distinct features and technologies that enhance their functionality and usability.

One of the main features of the VN-V25U and VN-V26U is their high-resolution imaging capabilities. The VN-V25U supports 1.3 megapixels resolution, while the VN-V26U boasts an impressive 2 megapixels resolution. This ensures that users receive clear and detailed footage for effective monitoring. The wide dynamic range functionality further enhances image quality in challenging lighting conditions, making sure that important details are captured even in bright and dark areas simultaneously.

The VN-V25U and VN-V26U models are equipped with powerful progressive scan technology. Unlike traditional interlaced scanning, progressive scanning captures the entire image in one go. This results in smoother video, reducing motion blur and providing clearer images of fast-moving subjects. This feature is particularly beneficial in environments where clarity is crucial, such as in retail surveillance or for monitoring public spaces.

Another impressive aspect of these cameras is their flexibility in installation and integration. They support Power over Ethernet (PoE), allowing for simplified wiring and installation processes, reducing the need for additional power cables. Both models offer various lens options, enabling users to customize their field of view based on specific surveillance needs. This adaptability is essential in settings where camera placement can vary significantly.

The VN-V25U and VN-V26U also incorporate advanced video compression technologies such as H.264. This enables efficient video storage and transmission, reducing bandwidth usage without compromising on quality. The inclusion of motion detection capabilities further enhances their functionality, allowing for intelligent monitoring and alert systems.

Finally, JVC's commitment to robustness is evident in these models. They are designed with durable enclosures suitable for both indoor and outdoor applications, ensuring that they can withstand various environmental conditions. Together, these features make the VN-V25U and VN-V26U series a compelling choice for those seeking reliable and advanced video surveillance solutions. Whether used in small businesses or large-scale facilities, these cameras provide the performance and security that end-users demand.
