The first thing to look for when buying a wireless window alarm is ease of installation. Most wireless alarm systems are relatively easy to install, though some can include complex directions. Aside from user-friendliness, a wireless window alarm should operate based upon battery power. Since the point of a wireless window alarm is to avoid wiring of any kind, avoid alarms that are not battery-operated.
In addition to seeking a wireless window alarm that is battery-powered, make sure that the alarm you choose doesn't require unusual batteries. Most wireless alarms include standard AA or AAA batteries, though some may include lithium ion batteries or other, more expensive, options. Many wireless window alarms can be activated and deactivated by accessing a control panel or box. For an alarm that's simpler to use, consider a remote activated wireless window alarm.
Purchasing an alarm that can be controlled via remote is a simple and effective way to activate and deactivate your alarm system. Again, look for a remote system that relies upon standard batteries. Some remote-controlled alarm systems may even come with rechargeable batteries, which are often preferred over regular batteries.
Another factor to look for when purchasing a wireless alarm is voice notification. When activated, some alarms project vocal warnings to intruders. Generally, expensive alarms combine both vocal warnings and flashing lights, while inexpensive alarms may only include vocal notification. Both types of alarms are effective, though some people prefer voice activation over visual activation.
While wireless alarms work very well in most circumstances, sometimes interference can block an alarm signal. Prior to purchasing any kind of wireless alarm, survey the area around your home. Trees, mountains, and large obstacles may present wireless communication problems. If the area that you live in is surrounded by possible obstacles, it's a wise idea to purchase a stronger wireless system. To find out if an alarm system is capable of crossing interference barriers, contact various alarm manufacturers. In some instances, a wired alarm may be a better option.
Lastly, placement ability plays a large part in determining which alarm to purchase. Some alarms must be placed precisely. These alarms will not function if they are placed in an angled area or on a surface that is not completely flat. Take a look at your current windows. If the trim around your window is ridged, make sure to purchase an alarm that can be placed at any angle. Considering all of the details mentioned in this article is the best way to choose an alarm system that will work perfectly with your windows.
