For resolution other than D1, the frame size per resolution can be calculated by multiplying a factor proportional to the resolution difference with D1. MJPEG file is created frame by frame.
D1 Frame Size Assumption (Kb)Īssumption of MJPEG frame size in this table is based on a specific activity scene type.
What is ip camera Pc#
If you concern about network bandwidth or PC performance for a multi-channel scenario, please lower both frame rate and bit rate.įor network speed dome cameras with continuous pan rotation, it is recommended to increase the bit rate by extra 50% for such high speed condition. Suggestion in above table for H.264 (MPEG4) is to balance the video quality and bit rate for one channel in daylight condition. Bit rate recommendation for IP cameras (Kbps) Technology If you want to estimate the bandwidth for multiple streams, please create a new specification for each one. Please refer to the camera UI for available settings while you are selecting resolution and frame rate to determine the suitable bitrate. The data recommended in this document is for one stream condition. In this article, we recommend bitrate and file size setting based on variant conditions and you are encouraged to choose the suitable one according to frame rate and resolution settings for getting the optimal result. Generally, higher bitrate means higher image quality, but since there is limitation for available network bandwidth and storage capacity for IP surveillance camera, a careful selection of bitrate and file zie is required for a balance between video quality and network bandwidth, as well as storage capacity. So a data rate specification for video content that runs at 1 megabyte per second would be given as a bitrate of 8 megabits per second (8 mbps). The data rate for a video file is the bitrate. Different from analog surveillance system, IP camera system requires user to have sufficient network bandwidth for video file transmission.
