Bandwidth and Storage
6.1 Bandwidth Management
In order to achieve efficient video transmission, it is important to evaluate your bandwidth requirements before
setting up an IP surveillance system.
6.1.1 Assessing Demands
Bandwidth requirements vary with the following factors.
● Resolution: the higher the resolution, the more bandwidth is required
● Complexity of the scene: the more complicated the scene, the more bandwidth is required
● Compression type: the lower compression ratio, the more bandwidth is required
● Image quality: the higher image quality, the more bandwidth is required
● Frame rate: the higher frame rate, the more bandwidth is required
6.1.2 Calculation
To assess bandwidth requirements, you can use Calculator.exe to evaluate the number of packets sent. You can
download the file from http://www.vivotek.com/downloadfiles/faq/audiovideo.
6.2 Storage
Besides bandwidth assessment, your storage space is also required to be evaluated, especially with megapixel
images.
6.2.1 Assessing Demands
The following factors must be taken into account when assessing storage demand:
● The number of cameras deployed
● Recording time
● Recording criteria, such as constant, scheduled or event-triggered recording
● Other factors such as codec, image quality and frame rate
