Most wireless cameras emit a signal that performs at distances of up to 300 feet, possibly more. With such a wide range, the wireless camera can be moved around whatever space you choose without the hassle of having to reconfigure your equipment. Also thanks to the wireless capabilities, these cameras are more resistant to tampering than their hardwired counterparts.

There are, however, a few drawbacks to wireless cameras. Inherent to all wireless products is interference caused by other wireless devices and electrical equipment. Physical obstructions (such as walls) can also cause the wireless signal to relay a weaker signal, resulting in poor performance. It’s also important to remember that cordless phones can interfere with the camera’s wireless signal. One solution is to use a cordless phone that operates at 5ghz or higher rather than the 2.4ghz frequency that more wireless cameras use.

Powering your wireless security camera is simple. If you’re willing to change batteries or rechargeable battery packs for better mobility, then look for cameras with such features. Otherwise, there are models that plug into a wall outlet. For battery-powered cameras, some power-saving features such as motion sensors are available to lessen the battery consumption, allowing for maximum performance even in precarious camera locations.

The first line of defense is the doorknob itself. Though always the first target of would-be robbers, a high quality knob will resist the effort of even the most expert criminal. More importantly is the deadbolt lock, a much more heavy-duty counterpart to the locking doorknob. Cheap locks, though, are vulnerable to a crude but effective break-in method called “bumping.” The intruder simply inserts a screwdriver into the keyhole, taps the screwdriver into the hole fooling the locking mechanism and allowing the lock to be opened. One manufacturer, Medeco, is known for a lock that is virtually impenetrable and while expensive, is well worth the peace of mind.

Other options include a door chain. While easy to overpower, door chains are relatively inexpensive, easy to install and could either deter the intruder or at least buy you some valuable time should you be home at the time of a break-in. A slightly more invasive option is installing a steel bar that slides down from the door itself into the floor.

While there is no foolproof way to completely secure your home, purchasing high quality door locks can increase your security and peace of mind. Visiting a home improvement store or lock manufactures’ websites can also provide you with valuable information and the last innovations in lock technology.
