Surveillance System Buying Advice
A good surveillance system is a key component to any home security system. Surveillance generally means to “survey” the surrounding so that you know what is around you and what should not be around you. Surveillance systems can include many different security devices all working together. These can be security cameras, video recorders, motion sensors, etc. Additionally, a central computer that can analyze the data from various surveillance devices is also helpful. In thinking about the
importance of a good surveillance system, consider the following:
The violent crime rate has remained barely unchanged through out the whole American continent in recent years. However, the statistics show that nearly all categories of crimes against property rose last year, including burglaries, vehicular thefts, possession of stolen goods and minor thefts. It's the first substantial increase in property crimes in over a decade. Important increases were also noticed for common minor offences, such as mischief, shoplifting and disturbing the peace.
On the other hand, authorities noticed a considerable decline in the shoplifting rate in stores that have installed surveillance systems. The newly developed digital recording systems gives you a clearer image better than the former video recording systems that uses cassettes. This means that it's easier to visually identify an offensive individual.
You are in the office and worried about home, could there be someone who sneaked into your room and move away your properties? Surveillance system now would be your total solution. The surveillance program running on your home PC attached with the webcam will monitor any motion detected. It will call your mobile phone or office phone or email you when a motion is detected. Upon receiving such a call, you can immediately launch your Internet explorer to check out images captured by your webcam at home. You
can also launch your Remote View software in your office and connect to surveillance system to check out what's going on at your home by watching real-time video. Even if you cannot use the Remote View software at that time, the surveillance system will record the event into video clips for you to view later.
Hard-wired surveillance systems use wires installed inside the walls, attics, crawl spaces, and underground to connect the sensors to a central controller. Surveillance cameras or microphones are also wired to speakers, video switchers, and video display monitors. A hard-wired system design normally uses power from the home AC power wiring as the primary source. Rechargeable battery pack is used for the controller as power backup during power outages. The main components of a hard-wired system are similar
to a wireless system but without the radio receiver and transmitter components. They include a central control panel, sensors, one or more keypads, motion detectors, smoke and fire sensors, cameras, camera switchers, video displays, and sirens. The advantages for a hard-wired security system are: first, hard-wired security systems are considered by most contractors to be more reliable than wireless systems. Secondly, professional security system technicians with warranties and maintenance support will help
you to install your system and make sure you will have nothing to worry about. Third, hard-wired systems avoid the problem of EMI and radio range limitations inherent in some wireless security systems. Forth, hard-wired systems do not depend on batteries except for power failure backup protection.
Buying Tips:
Make sure that the company that is selling or providing consultancy of security surveillance systems has certified security and video surveillance experts who are able to assess your particular home security needs. Because every customer has different home security needs, it is important that the surveillance system is tailored to fit your home specifically.
