Perimeter security needs

Traditional physical entity isolationSuch as walls, fences, iron fence. Simple, there is a degree of isolation. But only limited ability to prevent intrusion, almost no warning capabilities.

Technical isolationUsing 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 .

PerimeterSecurity

PERIMETER SECURITY TYPES

• 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

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

• 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

• 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

• 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.
