In reality, whether it is the monitoring of bank gates or the IPC used by tellers, vaults, and ATMs, HD has become an increasingly urgent need for the entire financial industry. The high-definition mentioned here refers not only to the clarity of the IPC, but also includes indicators such as IPC color restoration and image continuity. How to choose an IP camera?
In recent years, the application of IP HD cameras in the financial industry has become increasingly popular. China's agricultural and industrial construction and other major banks and even some local commercial banks and postal banks began to use IP HD cameras when they were building and upgrading security systems. Some industry experts predict that by 2015, the ratio of analog and IP HD cameras in bank monitoring can reach 1:4. In this case, future financial institutions will increasingly face the problem of IP HD camera selection and application. Here, the author specifically analyzes the IP HD camera selection problem in combination with the actual application needs of the financial industry, hoping to play a certain reference and reference for many domestic banks!
Selection point 1: HD indicators are in the first place
In reality, whether it is the monitoring of bank gates or the IPC used by tellers, vaults, and ATMs, HD has become an increasingly urgent need for the entire financial industry. The high-definition mentioned here refers not only to the clarity of the IPC, but also includes indicators such as IPC color restoration and image continuity.
From the perspective of clarity, no matter which of the above application scenarios, IPC resolution must be at least 720P. Only in this way can we ensure that the monitoring objects are seen to the utmost. For example, counter monitoring can see the characteristics of the ticket face and the details of the depositor's face, providing a strong guarantee for after-the-fact forensics.In terms of color reproduction, IPC has the ability to restore the color of the banknotes and the details of the picture, and even in the case of low illumination, it has excellent color reproduction. In addition, the continuity of the monitoring picture is also very important. In order to prevent the picture from being stuck and frame skipping, the IPC frame rate must be at least 25 frames/s to ensure a clear operation of the teller, even night monitoring. See clearly fast moving objects.
For example, BSR-IM2111-B0501, a high-definition gun-type network camera widely used in banking institutions in the Blue Star, uses a 1.3 megapixel image sensor with a resolution of 720P. In the ordinary real-time monitoring, the clear optical color can be obtained under the lowest optical zoom, the far and near shots are clearly presented, and the color reproduction is accurate. Even the vehicles that are in high-speed operation can be smoothly displayed without signs of jumping or smearing.In addition, the BSR-IM2111-B0501 also has excellent low-light and clear monitoring functions. In nighttime real-time monitoring, the basic illumination can maintain a relatively clean and high-definition color picture. When switched to night mode, the product automatically switches the color picture to black and white, maintaining a clean, clear picture quality even under very low illumination. It can be fundamentally monitored to prevent all night safety hazards. From the practical application requirements, products like the Blue Star BSR-IM2111-B0501 are more in line with the selection requirements of financial institutions.
Selection point 2: Wide dynamic image effect is essential
Bank monitoring, especially at the gates, is more intense during the day, and the light inside the door is relatively weak. If you want to be able to see the face coming in from outside, you need the camera to have excellent sensor wide dynamic effects. Moreover, the wide dynamic range is at least 120 db, and the wide dynamic frame number is also as high as possible (at least 2 frames).
In the early days of IPC, wide dynamic effects were generally inferior to traditional analog cameras. However, with the development of Sensor manufacturer technology and the continuous improvement of their software algorithms on this basis, the wide dynamic effects can be said to have been got a perfect solution. The Blue Interstellar HD Network Camera supports wide dynamics and clearly captures the image of the bank gate. Still taking the above BSR-IM2111-B0501 as an example, this product has a relatively excellent sensor wide dynamic function, and the dynamic range is up to 120db. When the wide dynamic is turned on, both the monitoring of the gate and the image effect of the indoor area can be obtained. Significantly improved, the details of the person's face, banknote color, denomination and so on can be clearly seen.
Selection point three: intelligent monitoring is increasingly important
At present, the front-end intelligent IPC is used in the bank's self-service banking monitoring. The main functions used are automatic identification of illegal card readers, regional personnel counting, bucket detection, and stop/stop detection. In addition, for outdoor monitoring, more and more banks need IPC with automatic alarm and intelligent functions such as fog-passing mode and corridor mode. Especially at present, the smog situation in many cities is becoming more and more serious. If IPC does not have the function of fog penetration, it can not even meet the outdoor monitoring needs during the day.
Faced with this demand, domestic manufacturers such as Blue Star have developed IPC products with various intelligent functions. For example, the BSR-IM2111-B0501 has the functions of lens shift alarm, surface correction, fog-passing function, corridor mode and lens occlusion alarm. The future application prospect of this intelligent IPC is also generally optimistic.
Selection point four: focus on low-stream network transmission
At present, most of the security systems of major banks have realized high-definition networked architecture. For high-definition monitoring information, high-definition transmission is also required. From the actual needs of IPC, the current Main Profile of 720P can achieve 3-4M, and the Main Profile of 1080P can achieve 5-6M. If High Profile technology is adopted, 720P can achieve 1-2M, 1080P can do 3- 4M. However, this kind of code stream is still under great pressure for the current banking network. When selecting relevant IPC products, banks need more IPC to have excellent performance of low-stream stable transmission, and the image compression standard is also Can reach H.265, as much as possible to reduce the pressure on the network.
In this respect, the blue interstellar related products also have unique advantages, such as the BSR-IM2111-B0501 using H.264, which has smooth code stream control and good delay performance in network transmission control, reducing the network. Bandwidth usage provides real-time, smooth video streaming. It is found by the code stream software that the video parameters are kept unchanged, the network bandwidth is limited to 6 Mbps, and the real-time code stream is about 5.9 Mbps. Under different network bandwidth limitations, the network transmission of this product is always controlled accurately and achieves the best effect of picture transmission.
For the major financial institutions in China, as long as they master the above four principles, they can basically meet the current and even future IPC application requirements. At the same time, in view of the fact that most cities in China have not yet issued the corresponding IPC standards for banking applications, bank users should choose more vendors with successful application cases in the market when they choose IPC products. At present, the core camera brands selected by major domestic banks include Blue Star, Haikang, Dahua, Hanbang, SONY, Panasonic, Samsung, and Ph.D., among which the proportion of domestic and foreign brands has reached 1:1. It is recommended that all financial institutions may choose among the above-mentioned domestic brands when purchasing products. While improving their own security monitoring level, they can also support the development of national brands!
