HD-SDI Speed dome ip camera coaxial cable to transmit uncompressed digital video signal, such as high-definition HD-SDI dome ip camera can provide 1080P (200 million pixels) 25 HD quality output, and due to the high-definition digital signal compressed processing, this high-fidelity signal processing and transmission, so that the integrity of the image to be protected, the image contrast is more real, more abundant amount of information. , HD-SDI 1080P HD-SDI cameras megapixels network camera quality comparison situation, whether it is from the color reproduction, image sharpness, signal-to-noise processing are superior for customers to provide more detail, more realistic effect of high-definition images. Real-time manipulation is the biggest advantage of the HD-SDI fast dome camera comparison IP Fast Dome IP video delay is mainly produced in the process of video compression and decompression, and network transmission process, and its extension megapixels network products when most of the more than 500ms, a need for the application of real-time PTZ operation fast dome camera products, such a delay is bound to miss a lot of opportunities for timely processing of the scene, it makes the actual operation of the user adverse emotions. Now IP Fast Dome Most of the products is encoded in H.264 or MPEG-4 compression format, such sports scene mode compression format stream than the general scene to be much larger, and fast The dome ip camera PTZ operation based on the scene changing application brought no small pressure mainly be interested in the device processing and network bandwidth applications. If you experience some of the complex network environment, multiple IP Speed ??Dome camera PTZ application and generate a larger stream, it may be difficult to ensure that all packets can arrive at the receiving end, is likely to cause the loss of image frames, reflected in the backend dropped frames, mosaic failure phenomenon, so also the IP fastball, stability and real-time manipulation of the image resulting in a greater impact. Summary, hd ip camera view is relatively obvious advantage in the rapid dome ip camera products, HD-SDI, HD-SDI fastball uncompressed, low latency and full HD features to customers bring full HD 1080p resolution images at the same time, to bring the customers like analog systems, real-time smooth handling applications, a real-time image requirements without delay PTZ application needs places, HD-SDI Speed Dome IP Camera product comparison IP Speed Dome camera products have a a more intuitive competitive advantage. Openness of IP surveillance system is like a "double-edged sword, it provides users with convenient and also for monitoring system network security risks, and HD-SDI application monitoring system similar to the analog control system, no compression digital signal for transmission on coaxial cable, and also there is the security risks of IP surveillance systems, higher reliability and stability. Compatibility is also a distinct advantage in the application of fast dome ip camera HD-SDI, and analog control system similar to both the front-end network camera equipment, the intermediate transmission equipment or back-end storage, control, display device, as long as compliance with the standard HD-SDI compatibility problems would not exist. Contrast, IP surveillance system, in terms of codec algorithms, Transmission Control Protocol, will be different manufacturers' design, different industry standards, different protocols understand and have great differences, such as Speed Dome ip camera products have their own proprietary protocol and ONVIF protocol with the domestic platform vendors, NVR manufacturers docking process, it will often appear different compatible situation, and sometimes it is difficult to unified. ONVIF protocol-based Speed ??dome ip camera preset point call control functions, because the understanding of platforms and vendors, often cause to spend a few weeks time, consume large human and material resources. HD-SDI system followed in the application of analog control system architecture simulation system of ideas can still be used to design, from the selection of equipment and systems architecture. Simulation system, the biggest difference is that the "HD", and the wiring of the analog system applied to HD-SDI monitoring systems, system components and device management mode are essentially unchanged, contractors, users can be very simple analog system can continue "HD" upgrade, just replace the front-end and back-end equipment, without the need for professional skills training, you can quickly achieve the "SD" to "HD" smooth upgrade the user has not changed, the quality is significantly improved, habits, cost savings, while easy to achieve high-definition. IP surveillance system, however, as it involves more IT expertise for most contractors, came from the era of analog systems integrators who will be some difficulties, and who use IP surveillance system will higher capacity requirements, these will design, construction, commissioning and application of IP surveillance system brought no small trouble.
