How to plug in the camera's hd line

How to connect the old monitor to the camera HD interface without hdmi port?

Usually, a VA or VGA interface can be used to establish a connection. There is no hdmi interface on the TV, which means that the TV does not support high-definition video input and cannot directly connect other devices (set-top boxes, players, etc.). ) use an HDMI cable. However, TVs generally have AV interfaces. You can connect other devices with an AV cable, and then switch the TV signal source to AV mode. If other devices don't have an AV excuse and only have an HDMI interface, you need to buy an HDMI-to-AV converter to connect the TV with other devices. The extended data TV box is connected to the hdmi-to-AV converter. The connection method is to connect the box to the hdmi interface of the HDMI converter, and then connect the 3RCA line to the AV interface of the TV through the AV interface of the converter, so that the audio and video can be output synchronously. Generally, the conversion process of hdmi-to-av converter requires high voltage, so there will be a power interface on the hdmi-to-av converter, which requires an external power supply of 5V0.5-1a.. The TV can be connected to the monitor and the VGA interface of the TV. The VGA signal output is audio-free, but the general HDMI-to-VGA converter has a 3.5MM audio interface, so you need to connect another 3. The MM audio cable is connected to an audio or television input interface to generate sound.

How to connect the camera's HDMI to the computer to collect data?

The HDMI interface can't collect data, so the camera can't connect the computer with HDMI cable to transmit data. Cameras with HDMI are all high-definition cameras. There are two ways to upload the video shot by the camera to the computer:

A. high-definition tape camera

① Connect the camera to an AC power supply through a power adapter, or install a battery for the camera.

② Turn on the camera switch and turn it on.

③ Insert one end of the 1394 line into the S terminal interface of the camera.

④ Insert the other end of the S-terminal line into the DV interface of the 1394 acquisition compression card on the computer.

⑤ Put the camera in the VCR playback state.

⑥ Open the computer's acquisition software to capture video.

B. HD hard disk/flash

Cameras that use hard disks or memory cards as storage media can be uploaded to the computer through the attached USB connection:

① Connect the camera to an AC power supply through a power adapter, or install a battery for the camera.

② Turn on the camera switch and turn it on.

③ Insert one end of the USB cable into the S terminal interface of the camera and the other end into the USB interface of the computer.

④ Open my computer/removable disk, and copy the video file to the designated folder of the computer.

Take the installation of surveillance cameras as an example. The specific connection steps are as follows:

1. Prepare to install camera accessories, including pliers, screwdriver, camera, camera charger, camera bracket, chassis and BNC connector, and connect them with BNC wires.

2. Pick up the camera bracket and install the chassis on the bracket.

3. Install the camera on the bracket.

4. Check whether the power supply is camera power supply.

5. Connect the power plug and the camera plug.

6. Take out the BNC wire from the head and cut off the copper wire in the middle.

7. Take out the BNC interface and tighten it with a screwdriver.

8. Fix the bottom with pliers.

9. After the two ends are connected, connect the camera with the computer host or camera hard disk.

10, after debugging, you can see the monitoring screen on the computer.

Installation monitoring needs to pay attention to:

1. Installation angle: there are mainly two types: cylindrical and hemispherical. Among them, the cylinder type is more common, and it is universal indoors and outdoors; Hemisphere is generally used indoors, which is small in size and can be installed on the wall or ceiling. Direct light sources should be avoided, and it is best not to install them against the light. Try to choose outdoor special support, zd, but the wind resistance coefficient is very different.

2. Installation height: The installation height of the surveillance camera should not be too low or too high, which will bring inconvenience to future maintenance. The recommended installation height is three or four meters.

3. Video line: The transmission distance of SYV75-3 line is within 300m, the transmission distance of SYV 75-5 line is within 500m, and the transmission distance of SYV 75-7 line is over 800m500, so "optical cable" should be considered. In addition, pay attention to the quality of "coaxial cable".
