Hard Vs Wireless Security Alarm Systems – How secure is your security system?
questions abound as a series of old constant spark debate. Which is better, Ford or Chevy, Coors or Budweiser, winter or summer?
Ask a few guys that alarm is better, hard or wireless, and you are sure to receive some opinions strong enough support in one way or another. Battle lines drawn, let the bottom of this boundary issues.
Loud alarm panels are cheaper wireless panels, but it is difficultinstall. Remember, if you plan to install itself. A home media system with a solid system for about 12-16 hours. Typical wireless installation in less than four hours.
Another consideration is that some types of building suitable for installation hard, and will use wireless needs. Most of all alarms business hard, and a large percentage of residential useaccess.
Even if you have a panel of wireless alarm systems, most require that some of the units is difficult. It usually consists of power transformer, electric wires on the ground, telephone and keyboards possible weapon stations and audible alarms. There are some exceptions to this, as some of the new all-in-one units currently offered with a base unit, the weapons station and alarm signals in a single device that is setto one of your existing telephone jack.
The biggest difference between a wired and wireless alarm panel is the way to communicate with all the protection that is connected to the system. A panel will require a hard wire for each "zone" or device on the system while a wireless system uses radio frequency to communicate with the "zone" or devices that are connected to it.
While a normal electrical circuit is a parallel circuit, a typical hard-wired alarmis a 2-wire circuit normally closed circuit with the end of the line charge is usually described as a series.
A series circuit, electric current to flow from the alarm panel, down a wire the alarm to open the device and back into the alarm panel. When the power is interrupted, the panel encountered a problem on the track record / Area . End of line (EOL) resistors in the field so that the alarm panel to monitor the situationarea for ground fault, short circuit and open or cut the wires.
More generally sealed units can be connected to an area with connecting devices in series with resistors mounted on the end of the line machine last in line. In this way, is completely controlled by the circuit to the panel last unit online.
When the wireless alarm systems for the first time on the market, were not the most reliable systems around. Most of them useUnattended transmitters to communicate wirelessly to each of the field devices. A-supervised wireless transmitter signal is not only a "one way" to the alarm panel when the receiver is activated.
For example, when a door or window is opened, the sender sends a wireless signal. The alarm panel to receive the signal and activate the area. The sender sends a signal not allow the door or window is closed, soReceiver area was cleared after a few seconds. With a wireless surveillance system you can actually arm the system with a door or open window, without even knowing it.
Most of the new alarm systems with a redundant bi-directional full control of wireless two-way communication between the transmitters and the alarm panel receives. With full control wireless alarm panel can tell the real-time status of a door orwindow. If a door is open, could be criticized area until the door is closed.
Most wireless systems in advance were very limited in their approach to systems. Using switches with binary addresses (explained below) to distinguish between the points of the system.
Okay if your wireless system is installed correctly, but what if your neighbor installed the same type of system? If the neighbors are directed movementthe same as the garage door, the alarm every time you start moving. As you can imagine, can cause a variety of difficult problems.
Modern wireless systems with serial numbers, tags home, or other proprietary technologies to ensure that only binary transmitters in your panel members was received from the alarm system. If the search and purchase a good reliable guide Buzzsystem do not have to worry about your next wireless transmitter to set the alarm.
Another problem with the non-surveillance older systems is that no one knew when the transmitter batteries are low or needs replacement. The only way to confirm that their task is to check periodically.
Because even sophisticated wireless alarm panels are mostly useless if the transmitter batteries are dead, somonitoring groups access is programmed to check with each of the remote transmitters at least once every 24 hours. If the transmitter has a battery bass, piano / station will be set up immediately an emergency.
With a wireless security system, you must always be the performance of your test system regularly. The level of wireless product can be influenced by environmental factors and the structure is installed. Moreover, the negative numberinfluenced by environmental factors, the form of electrical interference or even architecture sender and recipient.
So who is the winner of this topic? Well, the Underwriters Laboratory (UL), methods of installation more secure and reliable fixed by the end of line (EOL) or a two-resistance surveillance. In fact, UL approved installation standards for the federal government and other high security facilities that allin the protection of hard with full strength supervision of two lines.
Not to mention that wireless systems are an inferior product. In reality, all systems provide excellent protection, suitable for 90% of housing.
If you are considering a wireless alarm system, be warned, there are still sold and installed today that are not observed, so make sure each system is necessary to consideroffers a complete wireless.
If you choose a fixed alarm system, make sure the system is installed for the conservative opposition at the end of the line. If the installation faster and easier installation will be a place of resistors in the alarm panel, rather than the end of the line.
Although this method allows control of the area for earth fault does not mean giving protection to a direct short or worse yet, notjunction in the wire and shorted together, which is essentially loop so that the panel did not see the area open or closed.
