Closed-circuit television camera systems (more widely known as CCTV camera systems) are universally used to transmit the signals of a video surveillance camera trained on a particular area to monitoring systems in another area. There are many advantages of having CCTV cameras in your home, business or in public areas such as traffic intersections, major highways, train stations and airports. Here are the top five advantages of CCTV cameras. If you are looking for home security system then check out this page .
1. Protect Customers and Staff
When you own your business, whether you know it or now it becomes your responsibility to look after your staff as well as your customers. With CCTV cameras you can help protect both employees and clients/customers in a number ways. The primary way is protecting them physically. If they are attacked inside of your establishment you can turn over video of the attack to the authorities to help them find the assailant. CCTV can also stop crime from happening in the first place (see below) and can clear up any misunderstandings if money or merchandise goes missing.
2. Protect Your Company from Lawsuits
On the flip side, CCTV cameras can also help you protect your company from customers. We’ve all heard the stories of customers purposely putting glass or pests in their food in order to get a free meal, or purposely spilling water and slipping in it in order to sue a company. With a CCTV camera video surveillance system you can monitor any fraudulence going on, and prevent you or your employees from being accused of false accusations or phony lawsuits.
3. Monitor Employees
As much as you want to say you completely trust your employees, there’s always one bad apple that ruins the bunch. Unfortunately, it’s usually necessary to monitor your employees and make sure they aren’t stealing from your company – whether it’s office supplies, top-secret company information, client lists, store merchandise, extra free food or meals, or money from the till. With CCTV you are not only able to make sure your employees are staying honest, but you can see which of your staff are working the most efficiently and reward them accordingly.
4. Lower or Stop Crime Completely
As mentioned above, CCTV cameras can prevent crime simply just by being there to identify any suspicious activity. Whether used in your home, restaurant, store or office building, by recording a crime that is occurring, you can help catch the perpetrator, and get that criminal off the streets, helping to reduce crime not only in your area, but in your city or county as well. In addition, most criminals are hesitant to commit illegal activities if they know they are being watched or filmed, so you could help stop crime altogether.
5. Monitor Traffic and Public Areas
Last but not least, CCTV can be used to monitor traffic, identify traffic jams and record car accidents. CCTV is especially useful in hit-and-run accidents where a driver must be identified. CCTV cameras are also advantageous for public safety, as they keep a close eye on large crowded areas, such as the airport, subway, train station, etc., which are too big to monitor by authorities on foot.
With all of these beneficial advantages of CCTV, is there any doubt that you need one for yourself? Consider installing a CCTV camera system in your home or business today.

Gears are one of several fixed transmission settings in a vehicle used in order to determine power or direction. In industrial product categories, however, the gear is that toothed mechanical part – commonly a wheel or a cylinder – that engages with another toothed part in the transmission of motion from one rotating body to another. In this second definition, there are several materials used in the process. A popular subcategory is known as plastic gears.
Plastic gears are available in a wide array of materials and are constructed in different ways. It may also be designed depending on the industry that makes use of these items. They may be hubless or they may also have pins with or without set screws. They may also be set on a brass insert, a stainless steel hub, aluminum core, Bakelite or nylon. Below are further details about construction, design and materials in the manufacture of these items.
Construction
Plactic gears are produced through two significant processes known as hobbing and shaping. Additionally, though, some molding techniques are also employed in its construction. But then again, these techniques are not relied upon that much because of some disadvantages. Most of the times, molding strategies are not accurate due to mold variations and other inconsistencies. In all these techniques, though, plastic gear fabrication is not as favorable as metal gear processing.
Design – advantages and disadvantages
Despite the disadvantages seen in the manufacture and construction of plastic gears, more industries rely upon these industrial products. Their features have been enhanced through time and they are now designed to meet the requirements of their various applications.
Backing up the different plastic gear designs are some attributes or characteristics in the process. Designing these types of gears is considered a cost effective measure. It is also lightweight, has uniform parts, capable of shock absorption and has low coefficient of friction. Furthermore, it eliminates machining operations.
However, to some extent, the designs have some limitations too. They are relatively less capable of carrying heavy loads and they possess greater instabilities in terms of dimension. They are also affected by chemical products and lubricants.
Properties of different materials used in construction
Plastic gears are produced with different materials including acetal resins and copolymers as well as nylon resins. All of these materials have varied physical and mechanical properties whose strength, dimensional resistance, moisture absorption and fabrication requirements vary from one another. Generally, these materials have the capacity to withstand varied formulations.
