Cell phone detectors are used to detect cell phone transmission. They can sense the presence of a working mobile phone from distances of up to one and a half meters. These devices can be used to prevent people from using mobile phones in places like a court of law or examination halls. They can also be used to remind individuals that mobile phones should be turned off. But how well do they work? Keep reading below to find out all about cell phone detectors and whether they can really work:
How do Cell Phone Detectors Work?
As we mentioned above, cell phone detectors are clever technological devices that can detect the presence of a mobile phone within a certain area. They do this by capturing RF signals emitted by mobile devices. RF signals are produced by a mobile device when sensors on the device are activated. Optical sensors are an example of this. These sensors convert light rays into electrical signals. Once the light rays have been converted, the signals can then be detected by a cell phone detector.
When a cell phone detector has detected a cell phone, it will alert the mobile phone user and ask them to turn their mobile device off. Cell phone detectors can alert a phone user in a number of ways including:
Sending a text message asking the user to turn their mobile phone off – the operator of a cell phone detector can choose to write a customized text message or record a voice message to send to detected mobile phones.
Making a beeping sound on the mobile device or playing a ringtone
Cell phone detectors not only detect mobile devices that are in use, but also those that are in standby mode. These clever devices are able to detect incoming and outgoing calls, video transmission and SMS even if a phone is in silent mode.
Who Can Benefit from a Cell Phone Detector?
Cell phone detectors can be used to prevent the use of mobile devices in places of worship, hospitals, military bases, theaters, petrol stations, courts of law and examination halls.
But these aren't the only places that can benefit from this device. Another setting that can benefit from using cell phone detectors is a correctional institution. The illegal use of cell phones in these institutions is currently at an all-time high. Mobile devices in these settings are a huge risk to security as they can help inmates to commit crime both in and out of the facility.
Can a Cell Phone Detector Really Work?
Cell phone detectors are capable of detecting SMS, video transmission and incoming and outgoing calls even when the phones are in standby mode. While they aren’t currently capable of detecting all mobile phones, they are still extremely useful pieces of technology and they do work.
Trying to detect mobile phones being brought into secure facilities can be a labor-intensive and time-consuming challenge. However, businesses and places of worship can overcome this problem by purchasing a cell phone detector. These devices are the answer to the growing problem of unsecure, unauthorized and illegal mobile phone usage.
