HD Monitor is the development trend of the times , high-definition network camera technology determines its direction. To recognize the HD ip camera is not complicated , and this is the clarity and network issues. HD ip camera is mainly reflected in the clarity and accuracy of the screen, to achieve the clarity and accuracy of the screen, not just horizontal resolution reach 540TVL on the line must be wide dynamic , automatic white balance, image sharpness adjustment , Super digital Noise Reduction ( SNR ) , intelligent digital automatic metering compensation , the luminance signal , the signal edge color correction , automatic adjustment and restore damaged pixel , color adjustment, there is a concentrated expression of a wide dynamic range and other indicators, only achieve these comprehensive requirements to be regarded as a high-definition camera.HD ip cameras generally consists of lens, image sensor , sound sensor , A / D converter, image, sound, controller network servers, external alarm, control part of the interface and other components. Among lens, image sensor -based, network camera lens as a front-end components , and a fixed aperture, auto iris , auto zoom, auto zoom and other types of analog cameras with the same. From the technical point of view the product , there are some issues can not be ignored HD ip cameras,to the following points: the focal point of the offset issue, most of the major network camera body and lens combination of the two parts together, to achieve its high-performance depends on the perfect mix of body and lens. In monitoring the project, if the user or construction professional and technical personnel shortage , the camera and lens with the unreasonable , it will affect camera performance. In security applications , the user manually using multi -focus lens , however, dependent on manual focus eye visual inspection and manual adjustment, the efficiency is low, unsatisfactory accuracy . In addition, if a gun -type HD ip camera is susceptible to moisture , vibration, and other environmental factors affect the thermal expansion and contraction , in use for some time , prone to shift the focal point of the camera image blur caused by instability , rapid aging and other issues . The second is the back focus ( the focus ) adjustment problems due to differences between the network camera image sensor after the target surface uneven and different lens focal length , so the high-definition network camera back focus ( the focus ) adjustment techniques , has been the camera manufacturers need focus on research and development of technology. Early back focus adjustment method is the main focus adjustment ring + focus lock screw after the way locking screw after repeated adjustment very easy to damage the threaded adjustment ring , stabilized affect coke ; Another way is self -locking bevel an adjustment mechanism , usually plastic materials, in extreme environments because thermal expansion and contraction may cause the coke out of focus . In addition, some of the new approach is to use a more sophisticated and reliable thread focusing mechanism, but in the cost of inputs mold manufacturers will be more . Either the user or the network camera manufacturers are trying day and night can bring the same excellent quality. In order to achieve all-weather surveillance, in addition to expect high-sensitivity image sensor sensitivity , manufacturers had to use various means to improve the image quality under low-light environments . Such as using double day and night IR cut filter automatically switching mechanism , color to black , 3D digital noise reduction , digital wide dynamic image enhancement techniques. APEXIS's HD ip cameras use the industry 's first intelligent anti- exposure infrared night vision technology , in close cases, the Smart Start technology explosion of light at night to enhance image clarity and permeability, while its noise can be significantly inhibited , highlighting high performance products. HD ip camera is facing many problems to be solved , such as bandwidth pressure caused by high rate , the storage pressure , high-definition camera in the actual project selection and cost issues , and so on . At present , the application of high-definition network camera is still in its early stages , with the continuous development of technology, many problems will be gradually cracked , high-definition monitor becomes easier , HD ip cameras market will rapidly expand. So , to see the problem at the same time we must recognize that its future development direction , keeping up with market developments, to meet customer demand for the purpose of focusing on product availability . APEXIS's HD ip cameras can use cloud services, a variety of network penetration easy step to achieve remote monitoring, eliminating the need for a variety of complicated network setup , simple, very convenient. Cloud services have a distributed multi-server , and a large cloud portal provides support functions, including domain name resolution , cloud alarm , cloud pictures, cloud storage , cloud sharing , customers can enjoy these services through IE browser or cloud software. Most have high-definition network camera capture function , and each camera has its own IP address , the ability to PC, remote management platform for direct network connection . We can configure the built-in Email client in high-definition network camera , when access to the Internet , cameras and other equipment can also be through Email the alarm is triggered to capture images sent to the specified mailbox. You can also connect via COM interface device connected to the SIM card , using SMS , sent to specified handset under MMS . So not only do real-time monitoring and intelligent , but also can only use a very small bandwidth and cost. HD ip camera was able to surpass analog camera is dependent on the presence of 3G networks , high-definition network camera pioneered the era of wireless transmission networks. Wireless monitoring is also convinced of the advantages of each firm , and has been strongly recommended network camera to the civilian market . But the network environment is indeed an important reason for the rapid development of the constraints of network cameras , the arrival of 4G era undoubtedly gave the development of the network camera to bring the gospel . As a front-end products , high-definition network camera inevitable without the support of the back-end platform software . Therefore, the system software capabilities can be applied to scale the system scalability, system stability and operational aspects of humanity will become the next major competition in high-definition network camera point . Now the high-definition network surveillance , monitoring points and the system users are increasing and image clarity and improve the system in a high-definition camera , we can not expect that only one product is also compatible with more network video servers , NVR , and other products.
