1.Can I access the full functionality of the system by installing the client software or using the browser?
There are two ways to use CS/BS, that is, after the installation of dedicated client or directly through the IE browser (need to download the relevant plug-in) can directly use all the features.
2.What areas can network video monitoring apply to?
Mainly used in road monitoring, residential & community monitoring, Internet bar monitoring, education, health care, energy, safe city and other industries and home users.
3.How does motion detection work? Through the camera or software?
Motion detection works through the software in the DVR system by recording video when pixels in the image change. Most Security DVRs offer a sensitivity scale so the user can set the sensitivity of the motion detection.
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.
5.Video surveillance industry on the characteristics of storage needs?
Video surveillance on the storage needs of the following characteristics:
1) the flexibility of the storage capacity requirements are relatively large, the storage capacity of the number of screen quality requirements, the screen
The size of the size, the frame rate of the screen, the length of storage time and other factors, these factors are changes
Will make a large change in storage capacity.
2) the storage performance requirements are not high, but need to be able to meet the long time continuous data read and write, data flow
Large quantity, and less access to requests.
3) The data retention period is different and can be reused after the use of time. The number of general monitoring places
According to save a certain time (such as 10 days), later you can delete or cover.
The Key Technology of H.265+
H.265+ is an optimized implementation of H.265. The technology is a collection of intelligent encoding algorithms.
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.
2.Minimum Illumination Camera Indicator
Minimum illumination indicator This is an important parameter of the camera, but the camera parameters can be said that most indicators of mystery (not one).
The most low-light cameras, also known as the camera’s sensitivity. Factors affecting the value of the minimum illumination camera there are many, including the camera lens with the amount of light parameters (ie F value), a number of function parameters color temperature parameters, IRE video level amplitude level, and the camera settings. First, the amount of light parameters. A lens aperture of F1.4 the amount of light level is twice F1.2 lens, F1.0 lens F10 was 100 times the amount of light through the lens.
Thus, using different lens F value, determination of the minimum illumination value of the camera will have a decisive influence. Secondly, the color temperature of the light source.
