Portable Door Alarm

Updated on August 20, 2014

Do You Need a Portable Door Alarm?

Doors are a preferred target for would-be home invaders. Many intrusions are stopped by a door that is simply too difficult to break down or break through. Portable door alarms are often preferred since they require only seconds to install and are small and lightweight enough to easily be move when desired.

In fact, portable door alarms make for great travel door alarms as well. They are small enough that they are perfect for slipping into your luggage and taking along on a vacation or business trip. These devices can be very effective in scaring off intruders and alerting others to any type of break in attempt.

See some of the options below.

Portable Door Alarms: The Options

Many door alarms are either a bit too large to stick in a bag and take along or they are wired systems that don't lend themselves to travel anyway. If you're looking for a portable door alarm that allows you to take it along for added security in hotel rooms or to be able to easily install anywhere within your home, there are a few popular options:

1. Door stops.

Door stops are highly portable often weighing only ounces. They require virtually no installation as user merely need to slide them under the door. Most of them offer loud alarms that are very effective in scaring away intruders and alerting you and anyone in the vicinity of an entry attempt. They can also act as a barrier from allowing the door to open although they aren't as secure as some other options.

The only possible drawbacks are that some doors are mounted such that there is little space beneath them making it difficult to get the stop wedged under the door.

2. Door Security Bars

Door security bars which brace a door shut can be very effective at preventing entry. Some of them also have alarms. However, these devices are generally too long in order to pack them in most luggage and, therefore, they aren't considered portable in that sense. However, if you're interested in a these you can find these door security devices here.

3. In-Door Alarms

Some door alarms have a main unit that attaches to the door, usually hung over the door handle with prongs that are inserted into the opening between the door and door jam. These devices are also highly portable and easy to install for temporary use. They also provide alarms loud enough to scare off intruders but won't act to prevent entry beyond that.

The potential drawback with these types of portable door alarms are in situations where the space between the door and the jamb is a bit too wide. In these instances, the prongs can dislodge automatically rendering the alarm useless or resulting in false alarms. A small shim can help to remedy this issue. Some of these alarms are more versatile however and can also be used as a personal alarm or attached to other items to protect them from theft.

4. Door Alarms Which Mount with Adhesive

These portable door alarms are also small and light weight and require just seconds to install. However, because of the adhesive they are intended to stay where they are mounted. To use them for travel, strong two way tape would need to be used for re-mounting. Again, these alarms can provide a deterrent as they scare off intruders and alert users but perform no means of preventing entry beyond this.

      Even though they may sound like they function the same way, all burglar alarms work in a very different manner. In today's world, burglar alarms have now become a standard/essential commodity in every building. Security systems can be compared to the arms race, meaning, as the security to protect gets better, thieves and burglars have to find newer and better ways of breaking and avoiding the system. Even though burglary is bad, burglar systems have evolved due to this.
