Diagram of connecting an analog video camera to a computer

 

The connection diagram for an analog video camera is similar to that for a digital video camera. When forming this video surveillance system, it is necessary to use an analog video recorder. Another connection option is presented below.

In this diagram, the camcorder is directly connected to the computer. Analog video cameras can be connected to a PC using video capture cards. They must be installed in a PC system unit in a PCI or PCI-e slot. Has from 4 to 16 inputs for connecting analog cameras Distributor CCTV Jakarta. This method cannot be used for a laptop. Another option for connecting analog camcorders is to use a USB converter. It is considered the simplest and most inexpensive, and is compatible with any computer. This device is similar to a video capture card. They are compact, plugged into a computer USB port, but less reliable.

"In today's world, analog cameras are considered obsolete. They are being replaced by inexpensive, high-quality digital cameras."

The archive will be recorded on a computer, and remote viewing will be possible if it is connected to the Internet.
Diagram of connecting an IP camera to a computer

This type of camcorder is designed to connect to the Internet. Below are several options for wired and wireless (WiFi) connections. A 12V / 1A power supply is connected to the camera. Figures 1 and 2 show the wireless connection diagrams. The camera and laptop are connected to the Internet using a wired method, and communication between them is carried out via the Internet. This method works well if the computer and camera are far from each other. Another option is using WiFi. This method is convenient to use if it is not possible to lay a cable for transmitting video signals.
Figures 3 and 4 show a wired connection through an IP DVR and directly to a computer.

When connecting camcorders, you need to know which cable to use. For switching devices in these circuits, different types of cables are used. For digital and analog systems, a coaxial cable is used to connect the camera and the recorder at a distance of up to 100 m. If the cable length is more than 100m, we recommend using a twisted pair cable with twisted pair transceivers. Between the power supply unit and the cameras at a distance of less than 100 m, a two-core cable 2x0.5, more than 100 m - 2x0.75. A twisted pair cable is used between the computer and the recorder at a distance of up to 100m, and a fiber-optic cable is used over 100m.

When connecting IP cameras to the recorder at a distance of up to 100m, a twisted-pair cable is used, if the distance is greater, then a fiber-optic cable. Between the power supply and cameras at a distance of less than 100 m, a 2x0.5 two-core cable is used, more than 100 m - 2x0.75. A twisted pair cable is used between the computer and the recorder at a distance of up to 100m, and a fiber-optic cable is used over 100m.

Wireless connection of IP cameras using WiFi is possible at a distance of up to 100m. For longer distances, use WiFi hotspots.
