Check the video image settings. See the online help on Video and Image Settings.

 

Missing images in uploads.

This can occur when trying to use a larger image buffer than is actually available. Try

 

 

lowering the frame rate or the upload period.

 

Slow image update.

Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame

 

 

rates, etc, will reduce the performance of the camera.

 

Poor performance.

Poor performance may be caused by e.g. heavy network traffic, multiple users accessing

 

 

the unit, low performance clients, use of features such as Motion Detection, Event han-

Image gradually gets darker or lighter.

When using the AXIS 225FD in locations lit by fluorescent lighting, check in the

 

 

advanced image settings that the Exposure control is set to Flicker-free.

 

Image loses focus often.

Disable the DC-Iris lens in the settings for Video & Image > Advanced. Focus the cam-

 

 

era following the instructions on page 9, and then enable the DC-Iris lens.

Check the color level setting.

 

 

Check the setting for the IR cut filter. Images are shown in color only when this filter is

 

 

enabled, i.e. when set to yes or auto.

 

Blurred images.

Refocus the camera. Check in the Video & Image > Advanced - Camera Settings that

Lower frame rate than expected.

Check with the administrator that there is enough bandwidth available. Check also the

 

 

settings for bit rate control, in the Video & Image > Advanced > MPEG-4settings.

 

 

Using an inappropriate video object type can also affect the frame rate. See the online

 

 

help for more information.

225FD specifications

Axis Communications, a pioneer in network video solutions, continues to innovate with the introduction of the Axis 225FD, a cutting-edge fixed dome network camera designed to enhance surveillance capabilities in various environments. This device strives to meet the demanding requirements of modern security by combining advanced imaging technology with user-friendly features.

One of the standout characteristics of the Axis 225FD is its exceptional image quality. It boasts a high-resolution sensor capable of capturing detailed images even in low light conditions. This is further enhanced by Axis' Wide Dynamic Range (WDR) technology, which ensures that both bright and dark areas within a scene are clearly visible. This feature is particularly useful in dynamic lighting situations, such as entryways where bright sunlight may contrast with shaded areas.

The Axis 225FD is equipped with a built-in microphone to capture audio along with video, adding another layer of context to footage. This feature is invaluable for various applications, allowing security personnel to not only see but also hear events as they unfold, leading to more comprehensive situational awareness.

For adaptability, the camera supports PoE (Power over Ethernet), simplifying installation by allowing both power and data transfer through a single cable. This efficiency means less clutter and easier setup, making the Axis 225FD suitable for diverse installation environments, including retail spaces, offices, and public areas.

In terms of security features, the Axis 225FD supports multiple streams, enabling different resolutions for different scenarios. This flexibility ensures that users can tailor the video quality based on their bandwidth constraints while maintaining critical surveillance capabilities. Moreover, the camera is equipped with tampering alarms that send notifications if it is moved or obstructed, further bolstering security measures.

Durability is another critical consideration with the Axis 225FD. Designed to withstand the rigors of various environments, the camera is housed in a robust casing that protects it from dust and moisture, meeting IP66 and IK08 standards. This resilience ensures that the camera remains operational in challenging conditions, providing reliable surveillance year-round.

In summary, the Axis Communications 225FD is a state-of-the-art surveillance solution that excels in key areas such as image quality, audio capture, installation flexibility, and security features. With its durable design and advanced technologies, it stands out as a top choice for organizations looking to enhance their monitoring capabilities and ensure the safety of people and assets.
