Many current video image capture cards in security video surveillance systems have high requirements for multi-channel real-time performance. Therefore, this capture card needs to use products with stable heat dissipation devices, especially this type of video installed in the PCI slot of the motherboard. Capture cards and other types of PCI expansion cards are installed inside the host computer's chassis and have a small internal cooling space. Therefore, if you work continuously for a long time, many video capture cards will slowly become hot like the graphics card. Especially if you work continuously, the video capture card will gradually become hot and hot.
As we all know, electrolytic capacitors working at high temperatures for a long time will cause the electrolyte to deteriorate and the capacity will change. Similarly, if the video capture card runs for a long time in an abnormal working and stable environment, various ancient towns will inevitably appear, and then the system crashes and restarts is normal.
The non-meta capture card tells users that in addition to the heat dissipation and power consumption design of the video capture card itself, the installation of the video capture card and the heat dissipation design of the entire system are also key factors for the stability of the imaging system.
The professional streaming media capture card in the video capture card supports one card with multiple channels and one machine with multiple cards. Due to the development of the system interface standard, multiple capture cards can be installed on one host. About the installation of multi-card capture card. When the acquisition card is installed, it is usually installed one slot at a time, so that one is good for heat dissipation and the other is convenient for disassembly.
In addition, when installing or removing or replacing the video capture card, we need to remind everyone that because we always touch various accessories with our hands when troubleshooting, and the electronic components are afraid of static electricity, so we are touching the motherboard with our hands. When capacitive components, you must first completely discharge static electricity from your body, not to mention that you have no static electricity on your body. Especially in summer, due to the high temperature and low humidity, static electricity will instantly flow from a certain pin of the chip into the internal circuit when touching the board with hands, and it will also cause invisible damage. Therefore, before opening the main unit case, place the main unit on a floor without a carpet, and use both hands to touch metal objects to discharge static electricity from your body. If necessary, you can wear an anti-static wristband.
In addition, if the video capture card is used for a long time, excessive accumulation of dust will also cause poor contact of various components on the motherboard, resulting in poor heat dissipation. The capture card can be cleaned by referring to: Video Capture Card Dust Cleaning and Card Maintenance Precautions.
