5 Things To Consider Before Buying The Best Door Left Open Alarm

1. Is it loud enough?

The device has to be loud and powerful enough to scare off intruders. You can always increase the volume if it’s not quite loud enough. But, make sure you don’t set it too high as this will annoy your neighbors and risk getting them involved in any backlash against potential burglars.

2. Is this reliable, or is it cheap rubbish?

Not all door open alarms that sound like screaming babies! Some of them – such as the Provati Alarm, which uses an ultra-sonic sensor – offer some of the most advanced features around at a price usually on par with lesser devices. The point here is, don’t always go for the cheapest but look for something reliable and well built.

3. Is it waterproof?

One of the most important things to consider when looking for a door left open alarm is that it should be weatherproof if it’s outside or anywhere else where water can get into contact with it (such as bathrooms). Don’t buy one which isn’t suitable to operate in wet areas — you will be disappointed!

4. Do I need additional components?

If not, why pay extra money for things you don’t need? You might want to consider whether or not you need auxiliary switches, tube seals (to prevent dust and moisture from getting inside), power adapters (which may or may not be included), or digital keypads.

5. How long is the guarantee?

If you are spending good money on a quality product, make sure that it has a decent warranty and support service for peace of mind and long-term protection.

3 Benefits Of Door Left Open Alarm

1. Security for Your Belongings

A device that will sound an alarm when a door is opened without first disabling the alarm is an excellent deterrent to college burglars or thieves who might be tempted by your laptop computer or other electronics left out in the open. College students often move into dorms during orientation week before their official move-in date. This may mean bringing some belongings to school early before getting storage for more oversized items such as their bed or desk. If everything was brought inside by friends or family members, make sure the student leaves all windows and doors locked; using sensors on each door can ensure these windows will be safe.

2. Protection Against Intruders

If an intruder manages to break into the dorm room, the door left open alarm will immediately sound; it is loud enough to scare away anyone who might be trying to enter without permission. The alarm can also signal for someone walking by, allowing them to check if all is well inside the room before they enter themselves. This type of protective device does not need to take up large amounts of space – it will fit easily in your pocket or purse when you walk about campus at night.

3. Peace Of Mind

This type of security measure should give students peace of mind, knowing that one more level could help prevent intrusion or theft of their belongings. It can also prevent an awkward or embarrassing situation if a guest leaves the door open and the alarm sounds; this will be less likely to happen if the student can arm the alarm before going out, so they come back to a silent dorm room instead of one filled with noise from a continuous siren.
