The Key Technology of H.265+
H.265+ is an optimized implementation of H.265. The technology is a collection of intelligent encoding algorithms.
1. Storage
For before H.264 and H.265, video surveillance needs to record the video for 24/7, and it consumes huge storage. For H.265+, it nearly can save 90% storage.
2.Scene Adaptive Encoding Strategy
H.265+, it is to adopt differentiated encoding strategy according to different scene can effectively reduce human vision redundancy, thus to improve the encoding efficiency. For example, 4M bite rate with indoor objects will have similar human vision presentation with 1-2M for outdoor objects.
3.Flexible Reference Frame Structure
To reduce the bit rate and guarantee encoding video quality, comparing with the single frame reference structure of standard H.264 and H.265, Smart H.265+ adds more flexible reference frame structure. It adopts dual-frame reference and virtual I-frame technique.
4.Noise suppression technology
Based on the intelligent video analytics technology, the H.265+ technology generally separates/distinguishes the motion area from the background area and adopts different noise reduction levels for motion and background area. In this way, it can not only reduce the noise, but also guarantee the ROI video quality.
FAQ:
1. Some tips on using OSD menu for security camera.
1). Camera image can't switch to B/W at night ?
Open the camera menu to see if "Day & Night Switch" is set as "AUTO", if not, please change it into auto.
2). Noise is very obvious at night with low illumination.
2. How to choose a infrared camera?
Infrared camera is mainly used for the target needs day and night surveillance, with special emphasis on the need to monitor the night, and the target environment is not too strong light scene conditions. The specific choice based mainly on the camera and the target before the distance, the general distance of the infrared camera range of 20-100 meters, the farther away from the price the more expensive, while power consumption is also large.
In addition, the choice of infrared camera should consider the infrared light power switch control problems. This problem can be used both manual and automatic control.
3. What are the reasons for choosing a high-definition IP camera?
a: The progressive scan of the end of the analog camera is not clear
b: support PoE power supply, effective saving power supply costs
c: megapixel resolution is more clear than analog video
d: intelligent analysis can be integrated into the front-end to reduce the performance requirements of the back-end equipment
f: through the network control PTZ
g: two-way audio exchange through the network
h: through the network control alarm input and output
j: digital video encryption can be encrypted more secure than analog video
k: digital video transmission through the IP network more flexible distance farther and more economical and practical
l: Digital to avoid multiple analog-digital conversion to reduce image quality
All-digital optional open standard server hardware with lower total cost of ownership advantage.
3. What size monitor should I be using?
The correct size monitor depends on its use e.g. the number of images to be displayed at any given time, the viewing distance and the available space.
4. What are the advantages of network video surveillance systems compared to analog closed systems?
The information flow and the media flow of the network video monitoring system are digital and independent of each other. The hardware and software adopt standardized, modular and large-scale design concept. The configuration of the system equipment is versatile, open and flexible, Control functions, easy data processing, easy to use and system installation, commissioning and maintenance of the advantages of simplicity. At the same time, IP, the scale of digital products will bring cost advantages.
