Wireless burglar alarm systems typically use batteries as a power source for operation of the sensors, which renders them less reliable as well as requires increased inspection and testing of the sensors. Tampering is also much more evident with wired as opposed to wireless systems. Additionally, depending factors such as distance and the opposition of construction material through which the wireless signal passes, one or more “repeaters” may be need to be employed to increase the wireless signal level transmitted by the sensors back to the alarm panel. Costs associated with such repeaters will reduce the simplicity and increase the expense of installing the alarm system.
There are many inaccurate perceptions with wireless burglar alarm technology. For one, a common misconception concerns the assumed costliness of the system. Although when initially introduced wireless alarm systems were relatively pricey, as is common with electronic products, over time the cost has declined significantly rendering these systems attractive financially.
Another common misunderstanding is that “false alarms” can be set off by the sensors detecting family pets and small animals. However, alarm manufacturers have developed sensor technology which can differentiate the size of the detected object and can be therefore be set to reject objects below a certain size.
Another issue which was viewed as a negative with wireless alarm systems when first introduced was susceptibility to interference from electronic devices in close proximity like baby monitors, wireless phones, garage door openers, etc. were also alarm technology however has improved significantly in this area thus eliminating the effects of interference.
Finally, perhaps the most prevalent misconception concerning wireless burglar alarm systems is the mistaken understanding that contracting with a monitoring firm and paying a monthly fee is required along with the installation of the alarm system. Today, most wireless burglar alarm systems have the capability to program the system to handle the phone calls to local police and fire departments without the need for a monitoring service contract and monitoring fees. Also, even if a monitoring firm is deemed desirable, the fees charged for monitoring a wireless burglar alarm system can nevertheless be the subject of negotiation with resulting cost savings.
