H.264 Profile
The H.264 standard defines 21 sets of capabilities. These are referred to as profiles and they target
specific classes of applications. In the security industry, the most common are as follows:
Baseline Profile (BP)
Primarily for low-cost applications that require additional data loss robustness, Baseline
Profile is used in some videoconferencing and mobile applications. This is the most common
profile used in IP security cameras due to the low computational cost of processing the video
using this profile.
Main Profile (MP)
This profile provides improved picture quality at reduced bandwidths and storage costs and
is becoming more common as the camera processors (DSPs) become more able to handle
the processing load. Main Profile can save 10-30% over Baseline.
High Profile (HP)
High Profile is the primary profile for HD broadcast and Blu-ray HD disc media applications. It
can save 10-30% of the storage cost over Main Profile. However, it may also increase video
latency, depending on the stream structure. Quasar models default to the Main Profile to
provide the best trade-off between storage size and video latency.
