Surveillance equipment usually reminds one of “007” but with

the recent rise in crime rates it is more a necessity than just

spy equipment. The surveillance equipment allows you to keep a

watch even when you are not physically present at the scene.

These are used to monitor the behavior of people (like

stealing, harassing etc.) or procedures that do not act

desirably. These appliances are thus concealed and obvious.

Since there is always a chance of improper activity in places

like shopping malls, public schools, warehouses, parking

garages, airport terminals and offices, these places are the

ones mostly investing on surveillance equipments. A wide

variety of such equipments are available in the market with

highly developed technology.

Surveillance equipment mostly combines audio and video data

transfer and may range from Internet based equipment and

wiretapping phone to biometrics (advanced facial aspect

identification computer software).

The recent development of 'wireless' technology has its own set

of problems. The wireless devices transmit information either by

radio waves or infrared light, which can be intercepted.

Therefore, such devices are not reliable regarding the transfer

of important information.

Surveillance equipment is used to record conversation or acts,

but these are possible also on a normal recording machine. Some

options are:

• Clandestine miniature devices linked to a small microphone,

externally mounted to pick up the audio.

• Digital gadgets like minidisk recorders or the most recent

diminutive camcorders are small enough to be carried easily,

but produce very high quality recordings.

• The common ones encountered at offices for monitoring staff

are usually perched from a ceiling.

• The most advanced ultra-directional microphones, or parabolic

microphones can be used to overhear conversations from a hundred

meters away or more.

• Extreme clarity is possible only via a laser microphone,

which are again, expensive and highly technical to operate.

• Since mobile phones nowadays can record both audio and video,

therefore they can be used as surveillance equipments as well.

Surveillance equipments normally emit radio waves, however the

more sophisticated ones are not dependant on Radio Waves and

are extremely hard to detect. The only way to detect them is by

using sensitive gear to seek out magnetic fields, or the common

electrical 'noise'. Another way would be to use sensitive

infrared cameras for identifying waste heat of a Surveillance

equipment.

Gone are the days of the private eye, now you can get

information yourself via these fascinating surveillance

equipments. Finally, the best benefit these devices afford is

that they are successful in doing away with the incentive to

commit crime. Since a person’s inclination to commit crime is

decreased once he/she is aware that someone is there to keep an

eye on him/her.
