2. Anti-Theft System
Anti Theft System ( MINDWARE India Consulting )
Anti-Theft Systems are devices which prevent unauthorized access to Cars or other mobile systems. The evolution of Anti-theft systems has
ranged from simple key to RFID Tags, Bio metric Identification, and Palm Vein Recognition, etc.
The anti-theft systems are combination of smart sensors coupled with intelligent algorithms which can wisely distinguish between actual theft
and fake ones. Upon detection of theft they immediately raise an alarm or notify the user with necessary details like geographical locations,
time stamp , state of the device while theft occurred i.e.: If the anti-theft system is considered in automobiles , crucial data like whether the
engine was turned on , doors were unlocked ,etc. are transmitted to the owner.
Anti-theft systems protect valuables such as vehicles and personal property like wallets, phones, and jewelry. They are also used in retail
settings to protect merchandise in the form of security tags and labels. Anti-theft systems include devices such as locks and keys, RFID tags,
and GPS locators.

Passive and active anti-theft devices are the two options available when considering an anti-theft system.
Passive Anti-Theft devices automatically arm themselves when the vehicle is turned off, the ignition key
removed, or a door is shut. No additional action is required.
Active Anti-Theft devices require some independent physical action before they are set, such as pushing a
button, or placing a “lock” over a vehicle component part. This physical action must be repeated every time
the anti-theft device is set or it will not function.

Rf (Radio Frequency) Anti-Theft Systems
RF EAS Anti-theft systemThe Radio Frequency (RF) technology used in anti-Theft systems is based on a very thin, spiral-shaped LC
oscillating circuit, which is used to radiate into space the high-frequency electromagnetic waves needed to operate the system. Different
radio frequencies can be configured, but the one that is typically and most widely used is 8.2 MHz. The circuit, which acts as both
transmitter and receiver of the waves, is very simple and at the same time inexpensive. The systems placed near the shop openings
(antennas or anti-theft barriers) work in pairs, both as source and destination of the signal, so the process is as follows:
TRANSMITTING ANTENNA emits a constant radio signal in the immediate vicinity
The signal is intercepted by a LABELor by a TAG that is sufficiently close.
If the label or tag has not been properly disconnected using the appropriate equipment in the checkout counters (aDEACTIVATOR or
a DETACHER respectively), it will emit an additional signal
The signal is picked up by the RECEIVER ANTENNA: when it happens, the alarm is triggered.
IDISEC’santi-shoplifting systems with acousto-magnetic (AM) technology are very effective because the receiver is able to analyse the
incoming signal and assess whether it actually comes from a compatible anti-shoplifting tag or plate in the shop or whether it is a false
alarm.
The anti-shoplifting system with Radio Frequency (RF) technology offered by IDISEC is therefore a very useful solution for protecting the
goods on display from potential theft and is the ideal choice for a wide range of businesses.

Anti-theft Systems (Acousto-Magnetic)
Acousto-Magnetic (AM) technology applied to anti-theft systems is the latest and most
innovative one on the market. By using this technique, a physical phenomenon called
magnetostriction is set in motion, which affects all the Anti-theft accessories used to
protect goods.
Anti-shoplifting systems using acousto-magnetic (AM) technology operate at a frequency
of 58 KHz and involve inserting two thin metal plates into accessories such as tags and
plates.
In this way, the elements concerned are able to create a pulsed magnetic field.
7. As the LABEL or Anti-Theft PLATEis placed in a magnetic field, there is a shift in the distribution of electrons in the metal material (following its
magnetisation).
As a result, there is a change in the size of the plates inside the accessory, which begin to vibrate, expanding and compressing at a rhythmic
frequency, which can be identified as a characteristic signal: this phenomenon is called
With magnetostriction, the label or anti-shoplifting plate then emits a signal that is picked up by the system (specifically, by the RECEIVER).
Anti-theft systems with acousto-magnetic (AM) technology are very effective because the receiver is able to analyse the incoming signal and
assess whether it actually comes from a compatible anti-shoplifting tag or plate in the shop or whether it is a false alarm.

9. Antennas are major components in communication systems.
Transmitting antennas efficiently radiate electromagnetic fields and match RF systems to space.
Antennas may transmit or receive electromagnetic fields. Transmitting Antennas convert electric
current to electromagnetic fields. Receiving antennas convert electromagnetic fields to electric
current. In transmitting antennas, an alternating current is created in the elements by applying a
voltage at the antenna feed network, causing the antenna to radiate an electromagnetic energy.
In receiving mode, an electromagnetic field from an outer source induces an alternating current
in the receiving antenna and generates a voltage at the antenna’s feed network. Antennas are
used in outdoor and indoor communication systems. Antennas can be used in under water
communication systems. Antennas may be implanted inside human body and operate as
wearable sensors. Receiving antennas such as parabolic and horn antennas incorporate shaped
reflective surfaces to receive the electromagnetic fields and focus the fields to the conductive
receiving elements.

10. AM stands for Amplitude Modulation. In this page we will understand basic functions and specifications of antennas used
specifically for AM antennas.
Antenna couples two wire transmission line having impedance of either 50 Ohm or 75 Ohm with air having impedance of
300 Ohm.
The above image depicts typical AM antenna of loop type used for AM wave transmission and reception. Following are the
features of AM radiators or AM antenna systems.
• AM antenna systems are vertically polarized. This helps in better ground wave propagation as well as to have simple
antenna design.
• The electrical length of an AM antenna is usually 90 electrical degrees which is about 1/4 of wavelength or more. This
length provides adequate bandwidth and efficiency both.
Following are the typical specifications of AM antenna.
• Frequency: 520 kHz to 1700 KHz for Indoor use
• Pattern: Omni-directional
• Polarization: Vertical
• Impedance: Usually 350 Ohm for AM wire antenna, requires balloon to match impedance as desired.
• Application: In Analog TV systems to transmit picture/sound

Anti-Theft Systems are devices which prevent unauthorized access to retail stores or other mobile systems. The evolution of Anti-theft
systems has ranged from simple key to RFID Tags, Bio metric Identification, and Palm Vein Recognition, etc.
Anti-theft devices to consider for retail store-
Merchandising security
If you have high-value products in your retail stores like laptops, mobile phones or others, merchandising security is a great way to allow
consumers to pick up and test your products while keeping them tethered to your display furniture.
Some retailers use a security stand that mounts on top of their furniture and allows them to display phones, watches, tablets, and
cameras while keeping them secure and tethered. Have a look below:
There is a wide range of merchandising security equipment available, from magnetic holders, wired grip holders and others. You can
choose which ones are best suited to your products depending on the shape, size, and value of the products you’re safeguarding.
Some merchandising security devices come with in-built chargers so your displayed products are always charged to ensure a great
customer experience. You can find these devices (as well as the one above) in electornic stores as well as general retailers like Amazon.
Convex Mirrors :: Anti theft device for Retail StorePhysical locks and cables also make it harder for thieves to just pinch a product from
your shelves. Many retailers put mirrors all around their store, to improve the visibility of displayed products, such that thieves become
more conscious of their acts since they feel more ‘watched’. They’re cheaper, non-technical loss prevention devices that can be simple,
yet very effective.

12. (Smart inventory management tools-)
Anti-theft Inventory Management
One of the most effective devices to prevent inventory loss, is smart and frequent inventory management. By
watching your inventory like a hawk through regular stock counts and monitoring discrepancies, many retailers
dramatically decrease theft at their stores. Using smart barcode scanners to do stock takes to accurately account for
your inventory levels is helpful.
Another key measure retailers use is by monitoring ‘user permission levels’ of their staff for operating the POS
system. Vend allows you to set different permission levels, so only key employees can edit data on your system.
Taking these steps will ensure you know when something goes missing, which prevents culprits from stealing your
products!
