What Are the Different Types of Camera Surveillance?

The monitor is a monitoring software with outstanding performance of round holes. You can perform remote monitoring by entering the IP address and control password of the other party. The software uses the UDP protocol to penetrate the internal network. Without port mapping, users can connect to remote computers on any computer with Internet access for remote office and remote management. With the increasing popularity of surveillance systems in commercial and civilian applications, surveillance cameras (surveillance cameras) are widely used in various fields to escort social security. Video surveillance cameras are widely used in residential houses, real estate villas, shopping malls, shops, and finance rooms to protect law and order.

How to choose a monitor

1. Surveillance camera definition selection.

The clarity of surveillance cameras is generally 420 lines for civilian use, most of which are 480 lines, 520 lines, 600 lines, and 700 lines. The more lines, the clearer. The number of lines represents the sharpness of the camera, that is, the number of lines scanned horizontally on the monitor. Generally more than 600 lines represent HD cameras. There are a lot of false marks on the market. Some of the 700 lines are actually only 500 lines, which is a lot different. Often, the actual test has prevailed. With an ordinary TV face, the sharpness can be seen.

2. Distinguish the appearance of surveillance cameras.

The difference in shape is divided into a dome camera and a gun camera. The hemispherical type is named for the shape, which has the advantages of small size and beautiful appearance, and is suitable for installation in indoors, offices, hotel corridors, elevators, corridors, etc., and has better concealment. The hemispherical focal length is not large, which is suitable for illuminating objects close to the place. The gun camera is suitable for installation in all places, and there is no specific difference from the dome camera.

3. The distinction of surveillance camera lenses.

Generally, 3.6MM and 4MM are wide-angle lenses, that is, the range of the photo is relatively wide, that is, the range of the horizontal plane is relatively large, but the distance is widened, and the person becomes smaller, of course, the thing will become smaller and smaller with the distance Suitable for use in front of a store or a home, that is, when the object to be illuminated is 3-5 meters away.

4, the choice of monitoring camera interface.

Generally, the cameras on the market are BNC connectors. Recently, network interfaces and RJ45 interfaces are popular and transmitted through network cables. They are ultra-high-definition cameras, but the price is higher.

Monitor installation steps

first step

Take out the bracket and prepare the tools and parts: necessary tools such as plugs, screws, screwdrivers, hammers, electric drills, etc .; check the size and model of the plugs and self-tapping screws according to the predetermined installation position, and try the bracket screws and Check whether the screw base of the camera base is suitable, whether the pre-buried pipeline interface is handled properly, test whether the cable is unblocked, and enter the installation program when ready.

Second step

Take out the camera, and carefully install the lens according to the determined camera lens model and specifications (the infrared integrated camera does not need to be installed with a lens). Be careful not to touch the lens and CCD (labeled in the figure) with your hands. Power supply, connect to the host or use a monitor, small TV, etc. to adjust the aperture focal length.

third step

Take out the brackets, plugs, screws, screwdrivers, hammers, electric drills and other tools according to the positions determined in the construction drawings, and install the brackets. After checking firmly, install the camera according to the design direction; (Before confirming the installation of the bracket, first test it at the installation location to get a more reasonable monitoring effect).

the fourth step

1. If there is a lot of dust outdoors or indoors, you need to install the camera cover. After the second step, install the cover directly from here.

2. Open the upper cover and tailgate of the guard;

3. Draw out the fixed metal sheet and fix the camera;

4. Install the power adapter into the shield;

5. Reset the upper cover and rear bezel, straighten the cables, fix them, and install them on the bracket.

the fifth step

Insert the soldered video cable BNC plug into the socket of the video cable (use the two notches of the plug to align the two fixing posts of the video socket of the camera, and rotate it clockwise after inserting), and confirm that the fixing is firm and the contact is good.

Step Six

Insert the power output plug of the power adapter into the power socket of the surveillance camera, and confirm the firmness.
Step Seven

Connect the other end of the cable to the video input port of the control host or monitor (video machine) in the same way to ensure firmness and good contact.
Step eight

Turn on the power of the monitoring host and the camera, adjust the camera angle to a predetermined range through the monitor, and adjust the focal length and sharpness of the camera lens to enter the adjustment process of the video recording equipment and other control equipment. ^[2]
