防止丢失的手段

  The simplest solution for loss prevention.
  
  
• Bluetooth loss prevention tag
  Links with a smart phone.
  There exists various types of tags. i.e. a very thin tag, a tag equipped with sound generator, a tag equipped with a button, etc.
  
• Loss prevention tag without using Bluetooth
  This type of tag cannot connect to a smart phone and dedicated master device is required.
  The radio law differs depending on the country and needs to be attended.
  
  
• A service to find the lost mobile phone
  Some operators are performing the service to find the lost mobile phone
  using the GPS on the mobile phone.
  
  
• Bell（Normal Bell）
  If you attach a bell to your belonging, you may notice the drop.
  However the noise will be generated if you move.
  Also you may not notice the bell sound generated by the drop.
  
  
• DENSHISUZU
  DENSHISUZU generates the sound when it is dropped.
  So you can immediately find the lost item.
  
  

Scenarios for losses

• Left a smartphone at a restaurant.
  
  This can be prevented by using a Bluetooth loss prevention tag that generate an alarm
  automaticaly by the loss of connection.
  
  A Bluetooth loss prevention tag equipped with a button can call a smartphone.
  However, the radio coverage is limited and cannot reach the smartphone
  if you did not notice shortly.
  Calling to a smartphone is better way than this.
  
  You may also use a service to find the smartphone that is provided by the operator.
  
  
• Left a wallet at a restaurant.
  
  You can find the lost item if you use a Bluetooth loss prevention tag at the distance of
  several meters from the in restaurant.
  You should remember the location you were and it will not take time to find.
  
  
• Drop of a key at a road.
  
  A Bluetooth loss prevention tag has the coverage about 10 meters from 50 methers
  depending on transmission power.
  If you use a high power Bluetooth loss prevention tag that reaches 50 methers,
  it will be not easy to seek.
  There exists a Bluetooth loss prevention tag that can generate sound to notify
  the tag location but the sound will not reach 50 methers.
  If you use DENSHISUZU, you can find the dropped item immediately.
  
  The Bluetooth tag that reachs only 10 methers is also available. However link loss may happen due to Bluetooth radio issue.
  
  
• Lost key of bike that is used occasionally.
  
  If you do not usually carry the bike's key, the Bluetooth loss prevention tag is not suitable.
  Although it is possible to specify the position last connected with the GPS information,
  you can not use the alarm at the disconnection
  DENSHISUZU work equally well whether they carry things that
  they usually do not carry around or always carry around.
  
  
• Loss of key shared by multiple people.
  
  By using Bluetooth's loss prevention tag of the type that can connect with multiple smartphones,
  it is possible to search for keys using GPS information. In this case, you can not use an alarm by the link loss.
  If you use a DENSHISUZU, you can quickly find the drop.
  

If you lose it at home, you will often come out if you search.
If you lost it in a restaurant, you often find it when you call the store.
If you have lost it by train, you may find it when you call the train company.
What would you do if you dropped it on the street?
If you are lucky, it will arrive to a police box, but no one may deliver it to the police box.
If you use a Bluetooth's loss prevention tag, you need to seek a certain range.
If you use a DENSHISUZU, you can quickly find the drop.

The limit of Bluetooth's loss prevention tag

• Radio wave is unstable in the 2.4 GHz band.
  
  The radio waves used by Bleutooth are the same 2.4 GHz band as the microwave oven.
  Radio waves of this frequency are well absorbed by human body containing moisture like microwave radio waves.
  It is also easily obstructed by obstacles such as metal.
  Furthermore, it receives interference from Wi-Fi etc.
  In particular, in the case of a low transmission power Bluetooth tag with a radio wave
  reaching only a few meters, the connection may be lost and the alarm may sound even if it is nearby.
  Even if the performance of the Bluetooth tag is good, it will become unstable
  if the Bluetooth on the smartphone side is bad.
  Please be aware that the performance is different from car keyless entry.
  
  
• Tradeoff between stability and search range.
  
  In order to stabilize in the 2.4 GHz band, it is necessary to use a Bluetooth tag with high output.
  On the other hand, if you use a high output Bluetooth tag, the search range you need becomes wider.
  
  
• It is not suitable for things that you do not usually carry with a smartphone.
  
  Bluetooth loss prevention tag needs a link with a smartphone.
  Although it is possible to specify the position last connected with the GPS information,
  it is not possible to set the alarm at the disconnection.

  Let's select products by referring to product reviews.
  
  
• Cannot understand how to use it. The manual is only in Chinese.
