Security monitoring system and video monitoring acquisition card

The first point, playback quality

The most important function in the security monitoring system is to playback the historical video. The playback quality is one of the important performance indicators of the monitoring capture card. The genuine monitoring acquisition card should reach the 10-bit ultra-high-definition D1 image with no color distortion and no delay. It is very difficult to achieve this effect on pirated surveillance capture cards.

Second point, display resolution

As the security monitoring system, the resolution of the monitoring acquisition card is generally divided into the display resolution and the video resolution. The display resolution only refers to the display resolution of the desktop of the WINDOWS system. After the acquisition of the genuine capture card is performed, the resolution of 704 * 576 can be achieved when performing multi-screen segmentation. While recording and broadcasting, the resolution can reach 352*288/320*240. This is the resolution that the general monitoring acquisition card on the market can't reach. The pirated acquisition card is even less likely to be achieved. The pixel mosaic on the display that is recorded and broadcast with pirated capture cards is exposed and the picture quality is very poor.

Third, RMON

Remote monitoring is an essential function for monitoring the capture card, but there are still many engineering companies lack of confidence in remote monitoring. The remote monitoring function includes: multi-screen monitoring, video and playback, dynamic IP function, automatic connection after power off, remote control, remote configuration, status check, adjustment stream, two-way voice intercom, alarm function, multicast function And so on, the engineering firm should test whether it has the above functions and observe the remote image quality at the same time, instead of just looking at the fluency.

Fourth point, frame rate

The frame rate per second (fps) or frame rate of the monitoring capture card indicates the number of times the graphics processor can update the field every second. A high frame rate gives smoother, more realistic animations. In general, 120fps under the 100fps/N standard under the P system is a very good effect. The pirated capture card is only more than 75 fps frame rate, far less than 100 or more.

The fifth point, the function of the capture card

In general, the monitoring and acquisition card must have the following functions: image acquisition, recording, and remote transmission; collecting various alarm signals, realizing alarm linkage and transmitting them to the monitoring center of the centralized control station; controlling the motion of the PTZ and the lens; and controlling the matrix switcher to switch Video image. The piracy monitoring and acquisition card on the market is not completely accomplished.

The 7130 acquisition card is specially developed for video surveillance. It supports the development of the standard DIRECTSHOWAPI without secondary development. It can also provide secondary development SDKs according to the needs of different customers. And can be applied to the video webcast, streaming media, video conferencing and so on. At present, the 8 series, 9 series and AV series monitoring acquisition cards have realized the application of intelligent functions (smart brightness adjustment, intelligent local amplification).

The main advantages of the 8 Series, 9 Series, and AV Series Monitor Acquisition Cards are:

The first point, powerful data retrieval and analysis capabilities provide fast response time and investigation time

Second, more effective surveillance - security operators only need to pay attention to relevant information

Third point, fast response time - millisecond alarm trigger reaction time

The fourth point, intelligent brightness adjustment, intelligent local amplification

Sixth point, after-sales service

I believe we all know that the purchase of genuine purchases is a service. Many users value the price after purchasing a monitoring acquisition card . They often overlook the service. Many users who have purchased pirated products are not able to obtain engineering technology or product damage, and they do not receive the service. Timely service leads to their impact on local goodwill or interests. Therefore, users must improve their knowledge of anti-piracy and communicate through technical exchanges to feel whether the other party has service capabilities.

Today's smart video surveillance capture cards are suitable for security monitoring in industries such as banking, post and telecommunications, electricity, prisons, transportation, shopping malls, factories and institutions.
