Wireless systems are junk. Sorry.
If you talk to any well experienced alarm tech, he will tell you that a hard wired system is absolutely the way to go.
Companies flog wireless because it's quick and easy to install and they are out the door.
Hardwired is vastly superior because
1. Less prone to failure.
2. Cannot be hacked as easily.
3. No chance of interference
4. No bulky transmitters everywhere. Door pins are invisible for example.
5. Less prone to false alarms.
6. No constantly changing of batteries.
There are some very high end alarm systems out there and they are always wired systems.
It is not that simple cut and dried.

[h=2]Wired vs. Wireless Home Security Systems[/h]
Home security systems mostly all consist of the same components, including a central alarm panel with a keypad user interface, door and window sensors, motion detectors, heat detectors, smoke detectors, and even glass break detectors. One of the primary considerations necessary in choosing which alarm system is right for you will be the need to decide whether to get a wired or wireless home security system.
Deluxe Alarms
wired home security systems are composed of the alarm’s central control panel being connected with hard wires to each and every sensor installed in the home. The wires used to connect the devices are concealed behind walls and under floor boards similar to all other home electric wiring. Though they may seem cumbersome to install, there are many benefits to owning a
wired alarm system.
Sensors for
wired home alarm security systems are more affordable because they do not include any radio frequency electronics to communicate with the central control panel. These sensors are also constantly powered via the control panel, removing the need for periodic battery changing. One of the greatest advantages to owning a wired alarm system is that the sensors are not prone to being affected by interference through electronic appliances such as microwave or internet Wi-Fi signals.
A major concern with wired systems is the need for wires to be installed throughout homes to install each sensor. Fortunately, most new homes are built with the wiring for security systems preinstalled to every window and door so Home security systems installers can simply attach sensors with adhesives and the sensors to the wiring that is already in place. If your home does not have these wires preinstalled, Deluxe Alarms home security specialists will install them for you without causing damage to your home. It is a common misconception that the cost of installing wired systems exceeds that of wireless systems, however wired systems hardware comes at a lower cost. The advantages that come with owning a wired system will not require a greater investment.
Deluxe Alarms
wireless home alarm systems operate essentially the same way as their wired counterparts, with the exception of the use of radio frequency (RF) sensors to communicate with the control panel rather than being connected with hard wires.
Wireless systems are extremely easy to install since no wires are necessary beyond the control panel. The sensors are preprogrammed to communicate through radio frequency signals with the central control panel.
Wireless systems give the owners the flexibility to expand their system by adding additional preprogrammed sensors as easily as attaching them to their new locations using adhesives. These systems are also extremely easy to move to new homes since no wires have to be removed from the walls or floorboards. It is also impossible for criminals to attempt to cut wires in an attempt to bypass sensors and security cameras since they do not exist.
Both wired and wireless systems are extremely advantageous for home security protection. Deluxe alarms uses cutting edge technology, even if a wire were to be cut on wired systems, the alarm will be sounded, leaving wired systems with no real disadvantage next to wireless systems aside from ease of moving to a new home. If you intend to live in your home for a long term period, it would be wise to have a wired system installed. If you are planning to move in the near future, wireless systems are much easier to disconnect and reinstall in your new home.
And, there are hybrid systems, as well. we cannot make broad generalisations, although wired has an edge in terms of reliability.

Hardwired security system – Sensors placed throughout the building on doors and windows are wired directly to a control panel.
Pros
- More reliable than a wireless system.
- The system is less likely to have radio or electrical interference from other devices.
- Many of the components will be compatible with upgrades.
- Hardwired systems run on a/c power with battery backup in case of an electrical interruption.
- They offer a lower long term cost, no frequent battery replacement.
- Wiring can easily be completed while a building is being built or renovated.
- Connect through phone or computer system for remote monitoring.
- Good for medium to large businesses or homes.
Cons
- Can be difficult to install in some buildings.
- Hiding all the wires may be a challenge.
- Once installed, it may be difficult to remove and move to a new location.
- Labor costs can be higher.
- Renter? Will your landlord allow you to drill holes into the walls, floors and ceilings?
- Exposed wires can get damaged.
- Wiring a sensor to a particular point in the building may not be practical.
Wireless security system - Sensors placed throughout the building on doors and windows transmit signals to a control panel via radio waves.
Pros
- Relatively quick to install.
- Easier to reach inaccessible locations.
- Cost-effective installation.
- The system can be moved fairly easily.
- Flexible and can easily and quickly be extended to keep pace with a growing business.
- Suitable for smaller or medium commercial buildings.
- Good alternative for a concrete or cinderblock building.
- Sometimes it can be integrated with other wireless systems.
- Connect through phone or computer system for remote monitoring.
- No wires to run.
Cons
- More costly in the long run, replacing batteries can be costly and time consuming.
- There can be radio interference, sensor issues in large buildings due to the distance from the sensor to the control panel.
- Components can cost more.
Recommendations
Our recommendation depends upon the customer; we evaluate their needs, their building or buildings and property along with taking into consideration their security concerns. These concerns usually revolve around protecting people and property.
We try to provide the best security system solution to meet all of our clients’ needs. Some need a fully wired system because of the size of their building; some will need a fully wireless system because the building is concrete, while others will need a hybrid, a combination of both. Setting up a combined system works well in most situations.
The hybrid system gives greater flexibility, using both wired and wireless system components. These components can easily be combined, using the same programming, signaling and standard detectors. Sensors can be installed in areas where wires cannot reach, while more sensitive areas can be hardwired directly to the panel.
Whichever you choose it must be a reliable system, and always use a professional security system integrator to install your system. The knowledge and expertise will ensure the system is installed correctly and you will have the customer service to back up your new system.
