The method of installing monitoring equipment is as follows:
1, first determine the location and quantity of monitoring installation, the number of wires used, the number of hard disk video recorders and other parameters, then determine the corresponding equipment parameters and list, and then install the equipment list in the nearby technology market for procurement.
2. After the equipment procurement is completed, wiring shall be conducted according to the previously designed camera installation position and monitoring host installation position. Where there is a ceiling, try to run wires from the upper edge of the ceiling, and do not leave bare wires. Where there is no ceiling, conduit or trunking can be used, which is beautiful and generous.
3. After laying the line, install the monitoring camera and 12V power supply according to the key points of the previous design. Surveillance cameras need camera brackets and self-tapping to fix them. At this time, it is necessary to punch holes in the wall with an impact drill, plug the expansion plug, and fix the camera bracket with self-tapping. Then install the camera on the bracket universal joint.
4. After the front-end monitoring equipment is installed, the back-end equipment can be installed. The first scheme uses a video capture card, which is installed in the PCI slot of the supermarket computer and stored in the hard disk of the computer host.
Extended data:
Surveillance cameras can be divided into the following categories:
1, surveillance camera lens, in different applications, lens types can be roughly divided into:
(1) Wide-angle lens: The viewing angle is above 90 degrees, which is generally used in elevator cars, halls and other places with large viewing angle;
(2) Standard lens: the viewing angle is about 30 degrees, which is generally used in walkways, residential areas and other places;
(3) telephoto lens: the viewing angle is within 20 degrees, and the focal length is from tens of millimeters to hundreds of millimeters, which is used for remote monitoring;
(4) zoom lens: the focal length range of the lens can be changed from wide angle to telephoto, and the viewing angle range is wide;
(5) Pinhole lens: used for hidden monitoring.
2, according to the imaging color:
(1) color surveillance camera: it is suitable for distinguishing the details of a scene, such as distinguishing the colors of clothes or scenes.
(2) Black-and-white surveillance camera: suitable for areas with insufficient light and areas where lighting equipment cannot be installed at night. When monitoring only the position or motion of the scene, you can choose a black and white monitoring camera.
3, according to the resolution sensitivity, etc. ：
The (1) image pixel is less than 380,000, especially 250,000 pixels (5 12*492), and the product with the resolution of 400 lines is the most common.
(2) High-resolution images with more than 380,000 pixels.
