Surveillance video
For video surveillance cameras, the "guard job" day and night is naturally inseparable from the baptism of rain. So how do we protect our outdoor applications?
At present, many surveillance cameras on the market have a waterproof function. When rain falls, it can protect the machine well from rain. In fact, in addition to rain, the waterproof camera can also avoid the damage of wet weather to the monitoring equipment. In order to ensure the normal operation of the equipment for a longer period of time, for external monitoring equipment, configuring waterproof cameras is undoubtedly one of the most convenient and safest ways.
Of course, perhaps the impression of price factors, perhaps due to low utilization concerns, may be that many users feel that waterproof cameras are too luxurious for themselves. Well, such a video camera may require more attention from ourselves. For non-waterproof surveillance cameras, in addition to the outer shell of the fuselage is best to install a protective shell, in the camera's joints must be secured with a waterproof tape, as much as possible wrapped around a few times, To prevent water droplets from entering the joint directly threatening the fuselage. For other gaps, sealants are used for tight closure.
In addition, in the planning of the line, it is necessary to avoid the exposure of the line as much as possible, and it is better to choose some measures such as hot-dip plating to perform certain protection. Of course, wireless monitoring equipment can, to a certain extent, also be able to waterproof the equipment if conditions permit. In addition, it is also advisable to choose a more ventilated place in the camera installation position to avoid excessive water accumulation causing the machine corrosion to speed up.
Intercom equipment
For the intercom system, due to its special working principles and requirements, it is unrealistic to expect pre-set waterproof measures. Although we can install the radio into a waterproof case that has as good a seal as possible, it will only plug a few unimportant water points. Then, if our intercom equipment enters the water, how should we handle it?
For the equipment that enters the water, shutting off the power is the act that we must make quickly. Because every time the circuit works one minute longer, the risk of complete scrapping of equipment increases by a factor of ten. Afterwards, we must unpack the machine step by step, we must not easily let off even small parts - we must dismantle them one by one, and then use high-purity alcohol or special lotion to wash the circuit and circuit board, Then dry naturally. After the equipment is completely dry, we must also clean the stains on the circuit board to prevent corrosion of the equipment in future applications.
After cleaning, we need to soak it with absolute alcohol. After an hour or two, we remove it and dry it with a constant temperature hair dryer. And once again check whether the circuit board has damage, if there is a disconnection phenomenon, use the enameled wire as thin as possible to connect. Then use a circuit meter to measure if it is within the normal range. In general, the circuit board is the most influential one after the equipment enters the water. Therefore, whether it is a walkie-talkie or an intercom system, the inspection of the circuit board is absolutely meticulous and cannot be ignored after the invasion of the water flow.
Access Control
For waterproofing of access control equipment, under normal circumstances, it may be exposed to a small amount of outdoor rain. If you really want to encounter floods, it's probably not easy to waterproof or repair. The waterproof measures for access control are mainly focused on the protection of readers. As a matter of course, access control readers will have a small amount of rain protection. Of course, if the user is still not satisfied with the original measures, a simple plexiglass mask can be installed on the outside of the reader. At the same time, add a control box to the outside of the controller. In order to achieve as much as possible isolation from the outside world.
In addition, when selecting the sensing device, if the waterproof requirement for the device is high, it is better to select the button-type device for application. After all, compared with the touch type, the button-type waterproofing measure must be easier to implement. Similarly, for the main parts of the system equipment, its location is also best placed in the house to be placed, so that it will be more peace of mind for the waterproof work.
Anti-theft tools
Speaking of anti-theft devices, we mainly talked about the role of vehicle anti-theft tools in "treating water." In this disaster, many of the victims were killed because they were trapped in the car and escaped. In fact, in the face of a disaster, whether it is our commonly used anti-theft locks or fire extinguishers. It can be our tool for escape or self-defense. Especially for the strong gravity of protective equipment, I am afraid that there are few "heavy weapons" in the car.
In addition, on the choice of the escape route, we also recommend that you choose the side of the window to escape, after all, compared to the more flexible windshield, there is a certain degree of gravity capacity of the skylight, I am afraid that only the side of the glass is our "security weapon" It's best that the opponent's sudden rainstorm wakes up many people who are paralyzed. At the same time, it also allows us to reflect more seriously on our equipment capabilities. For security equipment, if it can still play a role in the disaster, then it will undoubtedly leave us more hope and even life. Therefore, to do a good job in the daily care of the equipment and enhance the environmental adaptability of the equipment, from small security to large scale, to life, is actually another guarantee for us to increase.
For the security industry, the flood disaster means the disaster of our equipment. Saying that we have absolutely nothing to do with torrents, how can we make these equipment better protected in heavy rain? Below, Xiao Bian has deliberately summed up some little knowledge about waterproofing of security equipment so that it can help everyone better respond to heavy rain raids.
