Practical suggestions for video monitoring system

Camera installation height

When communicating with customers, we often suggest that the customer's room is not less than 2.5 meters indoors and not less than 3.5 meters outdoors. Although these figures are simple but take into account the height of the room and the angle of the lens pressure, it also takes into account the outdoor installation The length and factors that prevent vandalism.

What are the recommendations for bracket installation?

When installing the camera, there are two options for wall mounting and lifting. The indoor environment for supermarkets is more and more hoisted, and the exterior is generally wall mounted. For example, the basement camera bracket is generally used for hoisting brackets. The length of the hoisting brackets is relatively long, and some of them need to be customized. Generally, it is necessary to measure how long the brackets are on site, some 100 cm, and some 80 cm. Most of the brackets are not standard. On the other hand, the weight bearing of the camera must be taken into account. It prevents the camera from tilting or falling for a long time. In particular, the ball machines that are being hoisted are heavy machines for the ball machines and must be securely mounted.

Indoor and outdoor what kind of appearance equipment

Different machines for the environment should also be different. Such as indoor coffee shops, boutiques, hotels and other similarly decorated environment, for aesthetic reasons should consider the dome camera, so it looks more beautiful. However, some food and oil stores, hardware stores, hot pot restaurants and the like are also indoor, but they must choose a bolt machine, which can effectively prevent dust, water vapor, fumes, etc. from entering the machine and affecting the use of the machine.

In some factories and power plants, cameras must be equipped with explosion-proof shields, and some need to have wipers installed to remove dust. Grain and oil shops, hardware stores, hot pot restaurants and other places, in order to prevent dust, water vapor, oil smoke, etc. into the machine's internal, recommended use of bolts. Boutiques, hotels, etc. focus on beautiful places, hemispherical machines are recommended.

What are the recommendations for using the power supply?

The use of power, it is recommended that no matter what machine should use foot safety power supply, the price is a bit high, but this type of power supply is stable, rarely after-sales problems.

The choice of camera power is a very important part, especially the choice of outdoor rain power supply, please buy good quality, or else a heavy rain repair.

Now most of the camera power supply methods use POE power supply, and the selection of POE switches has become the focus of attention, using well-known brands.

What are the reference suggestions for camera illumination?

The camera should pay attention to the irradiation angle of the machine after the image is output. Some customers looked good during the day after installation. At night, darkness, half whiteness, and blackness in the middle were observed. These are related to angles. We must avoid lifting the lens during installation. Too high, wall mounted machines do not have more than 1/4 of the white walls appear in the picture, the lens selection should be appropriate (such as 3.6mm and 4mm irradiation 6-8 meters, 6mm is suitable for 12-14 meters, 8mm is suitable for 20 -30 meters distance) If you really can't remember how to choose the lens, here's a simple way to teach it. It's the lens millimeters times 2 to choose, and then analyze according to the specific problems of the environment . The general effect of the front-end part is not bad.

The camera installation angle must consider the phenomenon of backlight

What are the considerations in the transfer section?

Selecting high quality wire reduces rework. In fact, the most troublesome and very important link is in the transmission part. Whether it is a cable or optical fiber or poor material selection or improper use, there will be many problems. Please support the national standard cable, no matter what brand you use.

If a large number of cameras are disconnected, how do you troubleshoot the fault?

If a camera with a large number of cameras is installed, if it is dropped, it is necessary to observe whether only one of the cameras is out of order or if a switch is lost. If there is only one out of regular switch, the machine may have Problems can be upgraded or restored. If the timing is not fixed, switch resources are insufficient. It is recommended to replace the gigabit switch (preferred TP-link, D-link, Huawei, H3C). One will have to consider switch and line problems. Switch is bandwidth, not full match is best!

What are the precautions when accessing the front-end IPC?

For a site with a small monitoring area, if only 2-3 IPCs are installed, the customer prefers to directly connect to the router, and then the computer installs software to display it. The use of the computer does not recommend more than three.

The use of video recorders is not fully recommended. One is the fear of occupying too much videotape resources, and the other is that if the user wants to increase later, if they are full before they need to replace the back-end equipment, and avoid waste, of course, these are It is necessary to speak with the customer. Storage above, Western Digital, Seagate's surveillance dedicated hard drive, now monitoring special disk and desktop computer's mechanical disk price is almost the same, a special disk is more stable, and second, the warranty time is more than a year, why not do it. Please use dedicated hard disk for monitoring.
