In recent years, the video surveillance market has continued to develop, and the industry environment has undergone major changes. The most obvious feature is that market applications are accelerating in various fields. Traditional security applications such as finance, transportation, and government have become more in-depth; emerging sectors such as education, energy, and factories and mines have grown rapidly; community and residential security applications have begun to heat up and gradually enter people's lives. In particular, individual users of surveillance cameras may not have enough knowledge of the profession to make a complete security plan. Today, a brief introduction to how to use surveillance cameras for personal protection:
Not expensive
Individual users are small businesses, and the general purchase and installation costs are not too high. In the field of surveillance cameras, there are many products that are cheaper and more effective. The production space of the individual store is small, and the ceiling is 57 meters from the ground. A spherical or hemispherical surveillance camera is available. If you choose a gun, it is too crowded. Due to the small space, the monitoring range of the selected surveillance camera is not too wide, as long as it can completely see the contents of the monitoring range in the background. Secondly, since the production of the storefront is in the place where there is a light source (it is impossible to turn off the lamp production), it is absolutely unnecessary to use a surveillance camera with night vision. Without night vision, the monitoring range does not need to be too wide. These two points make the price of the surveillance camera drop a lot, which is not expensive.
Only choose the right one
Monitoring production, it is impossible to achieve real-time monitoring, must be to monitor the video after work, then the choice of storage is very critical. Many times, after buying a surveillance camera, the user bought a large hard disk recorder. As a result, a lot of storage space is wasted and money is wasted. In fact, for the characteristics of the cake shop work, you must view the surveillance video every day, you can directly import the computer hard disk after reading. There is no need to get a big hard disk recorder. Many surveillance cameras now come with their own storage, enough for one day of monitoring. In the case that the funds are not sufficient, the simpler the monitoring, the better.
Home is an eternal topic for human beings, so it is especially important to monitor the security of the home.
Use in home security monitoring
As a typical representative of individual security, family security also has a lack of purchasing funds. However, choosing the best one is the best. It doesn't have to be sophisticated equipment, the key is to buy and use. Monitoring at home, I think it is still a machine that chooses to be short and fine, because the decoration in the home should be beautiful. If you choose a machine that is too big and too obvious, it will destroy the overall layout effect. Similarly, surveillance cameras in the home must pay attention to concealment in the selection, too large body will sometimes become the target of thieves.
When choosing a surveillance camera, the wiring problem must be taken into account. The decoration of the home is not specifically for security, so it is difficult to wire up. Therefore, this site recommends the use of wireless network cameras, such cameras are simple to install, powerful, enough to cope with home security.
Installation in home security
Maybe you have chosen a good surveillance camera, but if you install it improperly, it will make its performance greatly reduced. When installing the surveillance camera, because of the choice of the wireless network camera, its channel requirements are particularly high, so try not to have too many electronic products near the installation site to avoid interference from electromagnetic signals. When installing, try not to install it in the extension of the building such as the window, so as not to be damaged by external forces. Can be installed on the ceiling, such a view is a small view, not only the breadth and feel of monitoring, and it is not easy to be destroyed.
Video surveillance plays a pivotal role in the security market. In the future security market, it mainly tends to personal security. Because this society is built by every small family, video surveillance is mostly used for home security. In fact, security was originally defined to protect individuals and property from infringement. In the future, with the development of technology and changes in people's perceptions, this market will be a glory.
Heavy-Duty Powder-Actuated Fastening Tool is designed for hard base concrete which is between C40 and C55.
A powder- Actuated Tool (often generically called a Hilti gun or a Ramset gun after their manufacturing companies) is a type of nail gun used in construction and manufacturing to join materials to hard substrates such as steel and concrete. Known as Direct Fastening , this technology relies on a controlled explosion created by a small chemical propellant charge, similar to the process that discharges a firearm.
Powder-actuated tools come in high-velocity and low-velocity types. In high-velocity tools, the propellant charge acts directly on the fastener in a process similar to a firearm. Low-velocity tools introduce a piston into the chamber. The propellant acts on the piston, which then drives the fastener into the substrate. (The piston is analogous to the bolt of a captive bolt pistol.) A tool is considered low velocity if the average test velocity of the fastener is not in excess of 100 m/s (330 ft/s) with no single test having a velocity of over 108 m/s (350 ft/s). High-velocity tools may not be made or sold in the United States[citation needed]; however, some made decades ago are still in use in the shipbuilding and steel industries. The main manufacturers of Powder Actuated Tools are Ramset, Hilti, Powers/DeWalt, Tomarco and Simpson Strong Tie.
Powder-actuated Fasteners are made of special heat-treated steel. Common nails are not used for powder-actuated fastenings. There are many specialized fasteners designed for specific applications in the construction and manufacturing industries.
Powder-actuated technology was developed for commercial use during the Second World War, when high-velocity fastening systems were used to temporarily repair damage to ships. In the case of hull breaches, these tools fastened steel plates over damaged areas.[1] These tools were developed by Mine Safety Appliances, for the United States Navy.[2] Powder-actuated tools were investigated and used prior to this development; they were used in submarine hunting during the First World War and were the subject of a 1921 United States patent (US Patent No. 1365869)
