3. Traditional physical entity
isolation
Such as walls, fences, iron fence. Simple,
there is a degree of isolation. But only limited
ability to prevent intrusion, almost no warning
capabilities.
Technical isolation
Using moden technology to isolate the
protected area. Include: active infrared
radiation, shock and vibration optic fiber,
microwave, infrared night vision,
electronic pulse and so on. Can be
tangible or intangible isolation, with real-
time intrusion alarms and warnings
ability. in part techniques can directly stop
the intrusion .

PERIMETER SECURITY TYPES

4. • Easy to install & maintain.
• Minimal impact on the
environment.
• There are certain anti false
alarm features: small animals
such as insects or through
network security, because the
animals can not completely
blocking the beam, it will not
generate false alarms.
• Automatic lost power alarm:
When the power cord or signal
cable is cut, the alarm signal
output circuit will automatically
output wireless alarm signal
• Due to using infrared light
beam, so the system is easy
affected by the weather,
terrain and other relatively
environment. Direct sunlight
or rain and fog will affect its
sensitivity
• Paring installation, easily
have some blind spot.
• A high rate of false alarm
• Short lifetime
Advantage Shortcoming
Use invisible infrared light beam, and guard fence is formed between
the optical transmitter and receiver by an invisible multi-beam
infrared grating , as long as two or more adjacent beams of infrared
light is blocked, it will automatically send out an alarm.
INFRARED RADIATION DETECTION
Principle

5. VIBRATION FIBER DETECTION SOLUTION
• Easy to install, long lifetime, less maintenance.
• Construction convenient. Can be installed on a
protective network of fences, walls, or buried
underground.
• Has a strong anti-jamming capability.
• Passivity detection zone for flammable and explosive
places and can places strong electromagnetic
interference environment.
• Can be more precise positioning, various vibration
frequencies of climbing, fencing shear generated by
the invasion is very sensitive.
• Energy saving and environmental protection,
detection range and sensitivity can be adjusted
according to the application, the largest detection
zone of 40km.
• Anti-dismantle designed to make the system more
secure.
• High cost of overall
integrated equipment
Advantage Shortcoming
Based on the "fiber interferometer" principle, when the laser device emitting coherent
laser beam, interference optical signal output from the interferometer consists of two
fiber, if the fiber has not been disturbed by outside, the interference light signal will
remain unchanged; otherwise, such as: the fibers is receive acoustic or touch, it change
the output waveform of light interference and interference pattern generated by light
wave detector can detect this change, and the change of the waveform analysis features
through software, you can differentiate the event the real situation. Optical fiber
vibration detection is mainly based on vibration to determine whether there is intrusion.
Principle

6. • Weather factors affecting is
very small, snow, fog does
not cause false alarm
• The detection is three-
dimensional probe beam,
height and width can be
adjust from a few
centimeters to 10 meters,
detection effect works
effectively
• Can be used with infrared
detection reduce false alarm
• More complex installation
and calibration
• Microwave radio detectors
typically only installed in
open areas
• Easily have blind spots
• Higher false alarm rate
• Electromagnetic radiation
and lightning will interference
the radar system
• Microwave electromagnetic
radiation is harmful
Advantage Shortcoming
Microwave radio: microwave transmitter directional transmission and via
the environment (including the floors, walls and other objects detection
zone) reflector reaches the receiver. When an intruder enters the detection
zone (generate emission, absorption and so on), the receiver's ability to
receive changes (increase or decrease), the signal processor will analyze
and give warning or alarm signal.
Radar: working principle is based on the Doppler effect. Generates the
signal reflected from an object moving across the Doppler effect, i.e. the
frequency-signal and the reflected microwave signal transmitted wave will
produce a slight offset, then the alarm generated.
Principle
RADAR DETECTION AND MICROWAVE RADIO
DETECTION

7. • Concealed perimeter defense, can be put
in walls or buried underground which does
not affect the appearance of the
environment, and the invaders is hard to
avoided or destroy the system
• Zones can be laid in accordance with the
shape and other needs.
• Sensitivity is not ambient by temperature,
weather and other climate impacts,
• High reliability.
• High power consumption,
the cable need feed
power,
• Single-zone distance is
limited, typically less than
100 meters
• Soil moisture changes will
affect the accuracy, such
as ground water.
• High overall costs
Merits Demerits
a cylindrical electromagnetic field protection area will be formed between two
parallel underground leakage cables due to the electromagnetic induction , when a
body or metal move in this area, it caused electromagnetic disturbances and be
detected by the detector, then an alarm signal will be send out. For non-metallic or
non-human body, such as tree branches, cats or dogs etc., because of very weak
electromagnetic interference, it will not cause an electromagnetic disturbance. By
adjusting the sensitivity for the the detector, the outside interference can be
removed.
Principle
LEAKING CABLE DETECTION

8. • Intuitive and accuratecan
visually display the live
situation through the screen
• System can record,
playback, review,
automatically tracks and
records, etc.
• Enables remote monitoring
through a variety of
transmission network
• Can reduce the overall rate
of false positives through
early warning and alert area
with other perimeter
protection equipment
• In the haze, heavy rain
or at night without good
lighting environment is
less effective.
• Likely have monitoring
blind spot in some area.
• Slightly more complex
design and installation
• Slightly higher rate of
false alarming
Merits Demerits
Through using intelligent video analysis technology to do
the intrusion detection and perimeter intrusion warning.
Through the analysis of moving targets, can set multiple
alarm modes, such as: When people or things entering or
passing through the target area sending alert or people
stay in the warning area over a certain time.
