What people say about this software tool?

- “I purchased the IP Video Design tool and like it very much. Our business is to configure and install these type of systems. I really like the focal length feature to determine what 3rd party lens will be needed”.

M.Frost, US

- “I am very impressed with this tool! It really provides a point blank way of seeing “how much” bandwidth is being used”.

Ed S. One of the largest security system integrators, US

Using Field of View and Lens Focal Length tab you can calculate camera lens focal length, field of view and find best camera position.

To calculate the field of view or lens focal length of CCTV camera you need to know some parameters of installation. If you need to calculate the lens focal length you should specify following parameters:

• Distance - How far the target could be from camera.
• Camera Height - Camera installation height.
• Object Height - Height of the target. When you select object and camera heights the software calculates camera installation tilt.
• Object Width - Desired width of viewing area on target distance. If you modify this parameter the lens focal length and Horizontal Angle - Field Of View will be automatically recalculated. Other option is to specify Horizontal Angle (FOV) instead of Object Width. In this case Object Width and Focal Length will be calculated automatically.
• Camera Sensor Size - CCD or CMOS sensor format. You can choose from : 1/4″, 1/3″, 1/2″, 2/3″, and 1″. Usually you can find the sensor format in camera specification. Typical value for network camera with VGA resolution is 1/4″. For many cameras with CCD sensor - 1/3″. Megapixel cameras can use other formats like 1/2″ or 1″.

After you have specified these parameters the software will calculate Lens Focal Length and Camera Tilt.

In case if you have fixed lens with known focal length and need to calculate field of view you can just modify Horiz. Angle (FOV) parameter until you have desired value in Focal Length field.

To calculate network bandwidth of your CCTV cameras and get required storage space for video archives you need to add camera types and specify some parameters of your CCTV installations:

• Resolution - Camera resolution in pixels. You can select resolution from the drop-down list. List contains most popular PAL and NTSC camera resolutions (like 352×288 CIF PAL, 704×576 4 CIF PAL) as well as some typical network cameras resolutions (like 640×480) including megapixel resolutions (1280×1024, 1600×1200) and others.
• Compression - Video compression. You can choose from MPEG4, H.264, four levels of Motion JPEG (MJPG) compression (from Low to High) and “RAW Data”. If you use Motion JPEG you can use different JPEG compression levels. If you use low MJPEG compression (level 10) you get best quality of picture and about 10 times lower frame size. If you use Medium MJPEG compression (level 20) you get practically good picture quality and optimal Quality/FrameSize ratio. With JPEG level more than 40 your picture became bad for video surveillance purpose.
• FPS - Frames per second. Typical FPS for video surveillance - from 4 to 15 frames per second. In some applications (like CCTV in casino) it is required to use higher speed values (25-60 FPS).
• Days - Required length of video archive in days (24 hours). Used for storage space calculation.
• Cameras - Number of cameras in your CCTV installation with the same parameters.
• Activity % - Estimated motion recoding activity. 100% for constant recording. This parameter is used to calculate disk storage space in case if video is recorded on evens from motion detector.

As a result for each camera type you get:

• Frame Size (Kilobytes)- software can make frame size estimation based on resolution and compression. In some special cases you can measure your real frame size and specify it in this field.
• Bandwidth, (Megabits per second) - How much network traffic is required for these cameras.
• Disk Space, (Gigabytes) - Disk storage space required to store video archive.

At the bottom of the window you can find total bandwidth and disk space required for your video surveillance system.

To make proper bandwidth planning you should know practical bandwidth values for your netowork type.

• 1 Gigabit Ethernet - 500 Mbit/s
• 100 Mbit Fast Ethernet - 55..60 Mbit/s
• 10 Mbit Ethernet - 6..7 Mbit/s
• WIFI 802.11g 54 Mbit - 12..25 Mbit/s

The software calculates Frame Size estimations from Resolution and Compression using our own method based on our MJPEG frame size research.

Bandwidth and storage space are calculated using following formulas:

Bandwidth (Mbits) = FrameSize (Kb) * FPS * Cameras * 8 / 1024
Storage Space (GB) = FrameSize (Kb) * FPS * Cameras * Days * 24 * 60 * 60* Activity * / 1024 * 1024
