These days, it never hurts to be more careful. Much as we would like to believe in the inherent goodness of our neighbors, you just can’t stop the nagging feeling that your home is an open invitation for burglars and housebreakers if you don’t set up a sufficient security measure.

Driveway alarms, which are sensor-based devices that detect all sorts of motion that cross their path, are an important security measure for big and small homes alike. They are usually made of a transmitter, which detects the motion and sends a signal, and the receiver, which receives the signal and rings the alarm. When purchasing a driveway alarm for your home, it is important to keep the following things in mind:

There are four kinds of driveway alarms: wired, wireless, infrared, and metal detectors. It is important that you choose the type of alarm that is most appropriate for you. Wireless alarms are best used in households and business establishments because they are easy to install, maintain, and can actually be set up anywhere.

1. Determine your purpose

Determine your purpose before buying a driveway alarm. Some models can be integrated in full-house security systems that can display a live webcam feed or trigger lights when the alarm sets off. Others have their own built-in visual display, which can be useful for parents who need to watch their children on the front porch while inside the house. Still, other alarm types cannot detect small movements, such as that of an animal or an ultra-stealthy burglar. Find out your reason for wanting to purchase an alarm and base your decision on that.

2. Do not forget the technical details

For instance, you need to figure out how far the transmitter can emit a signal so you can install the receiver somewhere within that range. Also, some transmitters will not be able to send signal through certain interferences, such as walls, trees, or posts. A good choice would be to pick out something that can transmit a signal of up to 1,000 feet in an open area and 300 feet through interference.

3. Mind the price

Although we would all like to get a bargain for much of everything we need, security is one area where we shouldn’t scrimp down on. Some low-quality driveway alarms will sell over the Internet for $30 or less, but those are the ones that usually kick the bucket three days after installation. A high-quality driveway alarm is not as cheap as you would want it to be. The good ones are priced more or less $150 and up, but those are the good investments for the assets and for the family.

4. Weigh the add-ons

When choosing between two remarkable driveway alarms that have fairly similar prices, then take it down to the value-added services that each provides. Do they have back-up batteries, in case there is a power failure? You might be endangering the lives of your family when the electricity dies down. Are they waterproof? The alarms should still be able to work even when wet, or else, burglars abound during the rainy days.
