What Sets Off Walmart Door Alarms?

Items with affixed security tags might sets off door alarms at Walmart. Thanks to the embedded radio-frequency identification chip, the labels are monitored by the security team from afar. If the chip gets stolen and the sensor detects it, an alert will sound.

How do Walmart’s Surveillance Systems work?

  • Door Alarms

If the door alarms pick up a tag frequency that has been activated, it could mean that someone is trying to steal from the store and will notify security. At Walmart, sensors attached to the inside and outside of the main doors scan customers for active security badges. 

  • Surveillance Tags 

The use of magnetic security tags triggers door alarms. Magnets are removed from products at the checkout by scanning their barcodes. Therefore, labels are, more often than not, located next to them. Customers can still make purchases and pay for them at the designated register, even if a cashier is not present. As detected by a live tag, a person’s presence will trigger door alarms. When an individual attempts to leave the store with an item that still has a security tag attached to it, the alarm will go off. If a customer tries to remove the label on their own, they could trigger a second alarm or damage the product irreparably.

Items with A Walmart Security Tag

Products of high value that Walmart tags for safety include;

• electronics

• batteries,

• clothing,

• furniture,

• jewelry,

• make-up

• laptops

• mobile phones

• clothes, etc.

These high-priced products have anti-theft sensors that sound an alert if they get taken from the store without being paid. They pay the most attention to securing valuables since that’s what burglars want.

Items Without a Walmart Security Tag

Smaller and cheaper items, usually less than $5, like chocolates, toilet paper, soft drinks, etc., don’t have these sensors. Cameras monitor customers’ every step in the business to deter potential shoplifters.

Innocently set off Walmart’s entrance alarm?

It’s best to wait there until a worker comes over to assist you. Someone has to come over and check out your shopping cart right now. No one will immediately label you a criminal. Store employees are human and occasionally forget to attach tags to customers’ purchases. You must show the original receipt of items bought to whoever asks to prove the item. In addition, tags from other merchants can activate the entrance alarms at Walmart. If you shop at Walmart, you should check your bag to ensure you didn’t bring in a foreign tag.

Things That won’t set off Walmart’s Alarm

  • Barcodes

It is believed that barcodes may set off alarms at Walmart. However, there is no need for concern about the barcodes setting off the detectors at Walmart’s front doors. Barcodes can only be read by scanners in stores. These scanners can tell you how much something costs and other information about it. Alarms are regularly set off when RFID tags are placed too close to barcodes.

  • A shielded Tag

If a tag is protected by a material that doesn’t conduct electricity, the alarm won’t go off. For example, putting a piece of foil paper between the tag’s sensor and magnet can silence the warning. As a result of electromagnetic shielding, a simple aluminum foil bag may effectively accomplish the job. However, stores like Walmart take extra security measures to prevent shoplifting by those who are incredibly deft or clever.


There is no way to avoid setting off an alarm when active security tags are found at Walmart’s public entrances and exits. When purchasing some electronic items, apparel items, and even some types of make-up, the cashier must first disable the item’s security tag. However, with the current procedures in place, theft has decreased.

On the other hand, smaller, cheaper items like chocolates and soft drinks that may fit in a pocket are still prone to theft. Before you try to steal from Walmart, remember that door alarms are not their only security option.
