High Tech Tools of the Trade
|
|
|
|
Electronic tools CrimeFighters can use, such as cellular phones and
|
|
camcorders, rapidly and constantly improve. This chapter is intended to
|
|
provide general information only as it will eventually be outdated by the
|
|
passage of time. Talk to sales reps and read periodical literature to keep
|
|
up-to-date on new high tech equipment and current prices.
|
|
|
|
Cellular Phones
|
|
|
|
The most important piece of equipment for CrimeFighters is a cellular
|
|
phone. Radio Shack and other chain stores offer special discounts with
|
|
service contracts and activate the phone. The company that provides the
|
|
phone service pays the store a commission that amounts to the difference
|
|
between the store's regular price without the 12-month service contract.
|
|
Discounts a few years ago amounted to as much as $300, lowering the price
|
|
of a cellular phone to about $200.
|
|
|
|
Cellular phones are basically radio transmitters, with limited power up to
|
|
three watts. Because of the relatively low power for long-distance trans-
|
|
missions, receiver/transmitter/relay stations called "cells" are situated
|
|
along popular corridors beside freeways and major highways. Cells overlap
|
|
to form a relay when you progress through one cell to another. That makes
|
|
it possible to use them in cars. These cells hand-off (relay) the conver-
|
|
sation to the next cell as you travel. In some areas, off the main high-
|
|
ways, there may not be any receiving stations and the use of a cellular
|
|
phone isn't possible. But it won't be long before that problem is solved.
|
|
|
|
Excerpts from the Toronto Globe and Mail: "Telesat Mobile, Inc. has reached
|
|
an agreement with French-based Arianespace to launch a satellite in 1994
|
|
designed to improve mobile communications throughout North America. Once
|
|
the satellite is in operation, individuals using portable computers,
|
|
portable fax machines and a new generation of cellular phones will be able
|
|
to send and receive messages throughout North America... the satellites
|
|
would be particularly useful for sending and receiving transmissions in the
|
|
85 percent of North America that is not now served by cellular phones."
|
|
|
|
Costs
|
|
|
|
The receiver/transmitter/relay stations are serviced by firms who charge
|
|
for the service. Cellular One, of Yuma, Arizona, has the following:
|
|
|
|
V.I.P Plan -- for low volume users -- charges a flat monthly rate of $29.95
|
|
for basic service called an access fee, whether you use the phone or not.
|
|
In addition when you use the phone, for all incoming or outgoing calls, it
|
|
costs an extra 38 cents per minute during peak air time (from 7 a.m. to 7
|
|
p.m. Monday through Friday. At other time (off-peak) the rate drops to 24
|
|
cents per minute. There is no free air time.
|
|
|
|
The Business Plan is for higher usage. The monthly access fee is $59.95,
|
|
peak rate is 35 cents and the off-peak rate is 20 cents, and the extra $30
|
|
for the access fee allows 100 minutes of free air time. Actually, the "free
|
|
air time" cost $30, or at a packaged rate of 30 cents per minute for extra
|
|
air time. If you use the phone frequently during business hours, this plan
|
|
gives a volume discount.
|
|
|
|
The Executive Plan is for busy people who use the phone a lot -- like a
|
|
business executive. Monthly access fee is $99.95, peak rate is 32 cents and
|
|
the off-peak rate is 18 cents, plus you get 240 free minutes of air time.
|
|
Or the 240 minutes cost $70 per month more than V.I.P. service, and the
|
|
"free" air time of 240 minutes cost 29 cents a minute -- whether it's peak
|
|
or off-peak.
|
|
|
|
You are charged for air time whether you make an outgoing call or someone
|
|
calls you. Since you pay for air time when people call you on your cellular
|
|
phone, don't give out that phone number for regular use -- unless it's a
|
|
business necessity (or you can afford large phone bills). If you're a
|
|
ratchet jaw, or have a teenager lurking close by to use your phone when
|
|
you're not looking, the extra charge for air time can cost a bundle. Keep
|
|
and use a regular phone besides the cellular phone. Reserve the cellular
|
|
phone for emergency calls, business, and on-the-road use.
|
|
|
|
Long distance calls are still put through as long distance calls. Your call
|
|
is picked up by the nearest cell and connected to a long distance telephone
|
|
line in that cell. You are then charged regular long distance rates in
|
|
addition to air time. The long distance connection allows you make calls to
|
|
virtually anywhere in the world. (The downside: you get stuck for the air
|
|
time when people call you long distance -- even wrong numbers.)
|
|
|
|
Regular telephone features, such as call waiting, call forwarding, call
|
|
transfer, no-answer transfer, no-busy call forward, and 3-way conference
|
|
calling, are available for an extra $2.50 for each feature, or $6 per month
|
|
for 3 or more. There's dozens of various hardware features for cellular
|
|
phones which are too numerous to mention here.
|
|
|
|
Radio Shack Deals
|
|
|
|
Radio Shack in Yuma uses Contel Cellular phone service, which has slightly
|
|
different rates. Monthly service is $30, peak time rate is 40 cents per
|
|
minute, off-peak time rate is 20 cents per minute, and no free time. But
|
|
Radio Shack charges a $25 "activate" fee to program the phone to you new
|
|
telephone number, etc. The latter is a one-time only fee, unless you change
|
|
your number.
|
|
|
|
The difference between Cellular One and Contel is insignificant. For
|
|
example, let's say you use the cellular phone strictly for emergencies and
|
|
CrimeFighter calls which might total about 30 minutes per month. For simple
|
|
calculation, assume you use the phone 50% of the time during peak time and
|
|
50% during off-peak.
|
|
|
|
Your costs for Cellular One: $29.95 monthly service fee, plus 15 minutes at
|
|
38 cents = $5.70, plus 15 minutes at 24 cents = $3.60, or a total of $39.25
|
|
per month.
|
|
|
|
Your costs for Contel: $30 monthly service fee, plus 15 minutes at 40 cents
|
|
= $6, plus 15 minutes at 20 cents = $3, or a total of $39 per month.
|
|
|
|
Chain stores like Radio Shack are numerous and convenient. If you have
|
|
mechanical problems, they'll fix or replace the instrument. Other models
|
|
may have to be sent to a repair depot and may take weeks to get it back.
|
|
|
|
Camcorders
|
|
|
|
The second most valuable piece of equipment for CrimeFighters is also the
|
|
most expensive, about $1,000 or so. They aren't essential, but videotapes
|
|
provide the best evidence possible when you make a "movie" of lawbreakers
|
|
committing a crime. If you're serious about being a full time CrimeFighter
|
|
you'll want one sooner or later. I'll skip the mechanical description and
|
|
concentrate on the models and features available.
|
|
|
|
VHS format is the most popular. Beta models are obsolete. Sony has a "new"
|
|
Beta format called Extended Definition (ED) Beta. This one's disadvantages
|
|
outweigh its advantages for CrimeFighter use. Forget Beta models.
|
|
|
|
VHS Camcorders (cameras) are available in standard format, compact format
|
|
VHS-C, Super VHS, and 8mm. Compact models are usually marked as VHS-C. The
|
|
cartridge and camera are smaller and lighter in weight. The tradeoff is
|
|
they have a smaller amount of recording time available, about twenty
|
|
minutes at the fastest speed (which makes a better picture) and ninety
|
|
minutes at the slowest recording speed. A cartridge adapter allows the use
|
|
of compact tape cartridges in a standard VCR. The adapter sells for about
|
|
$40 via mail order. The limited recording time is a tradeoff for lighter
|
|
weight and smaller bulk.
|
|
|
|
S-VHS produces a super high-resolution image which provides a much better
|
|
picture, similar to the high-res screens on computers. The drawback is that
|
|
standard TV screen can't show the details in excess of 240 lines of
|
|
resolution. S-VHS cameras make superior pictures, but you won't find many
|
|
super high-resolution TV monitors to take advantage of their high
|
|
resolution image.
|
|
|
|
Eight millimeter tapes and cameras are the smallest and lightest. Recording
|
|
time is about two hours, the same as standard VHS models. A small drawback
|
|
(or benefit) is, in 8mm format, the camcorder is also the VCR playback
|
|
machine. You hook up the camcorder to play back through your TV -- like
|
|
hooking up your VCR player to the TV. Using a VHS VCR, you can copy the
|
|
8mm tape to VHS format, or vice-versa.
|
|
|
|
At the time of this writing, the top of the line was a Sony EVC-X10. Radio
|
|
Shack or similar stores won't have them because of its unusual features
|
|
(for professionals) and its price. It listed for $3,900 (1989). Street
|
|
prices on computers run about 50% of list prices shown in news releases.
|
|
That lets stores offer discounts. The markup on Camcorders is about 25%,
|
|
so a realistic discount price you might get is 10 to 15% off list price.
|
|
|
|
The Sony EVC-X10 is an 8mm video camera recorder. The main feature is that
|
|
it accepts any C-mount video or photographic lens, including wide angle,
|
|
high magnification zoom, telephoto and night vision lens. It also accepts
|
|
16mm film-type lens with commercially available adapters and can be used
|
|
with microscopes and telescopes for some pretty specialized work. It comes
|
|
with a broadcast quality 1-to-14 zoom lens which is the equivalent to 40-
|
|
560mm SLR (camera) zoom lens. (For example: with a 500mm camera lens you
|
|
can record a close-up of your subject a block or two away from the camera.
|
|
|
|
Compact and lightweight, the Sony EVC-X10 features a high density (420k
|
|
pixels) 2/3" precision CCD color imager, 2 lux sensitivity (night vision
|
|
lens may improve low light performance); an auto and manual iris control;
|
|
adjustable high precision external view finder; simultaneous time/date
|
|
generator; auto white balance; edit and review capabilities; and, a
|
|
variable speed shutter from 1/60 to 1/2000 of a second. Additional features
|
|
include a built-in mike, battery lamp, audio/ visual output jacks with RFU
|
|
power supply for playback on TV, five pin remote connector, external mike
|
|
input (for CamEar zoom or directional mikes), 11 function external LCD
|
|
panel, eight function internal VF display, and noiseless slow/still frame
|
|
advance. It also comes with an attachable pistol grip and shoulder frame to
|
|
increase balance and comfort, but it also mounts on a standard video tripod
|
|
- handy for stakeouts.
|
|
|
|
When you can afford it, get this one or its successor model. Ask your local
|
|
dealer who handles Sony products. Shop for prices.
|
|
|
|
If you can't afford the Sony EVC-X10, the alternative might be a Panasonic
|
|
PV760. It has a computerized 1 to 30 power zoom, two lux, and lists for
|
|
$1,499 (1989). They are available from Tandy's subsidiary stores, Video
|
|
Concepts, which are located in many cities throughout the United States.
|
|
They had them on sale last year for $1,299.
|
|
|
|
PV760 features are: 30:1 digital zoom; 10 W color enhancement light; 12 X
|
|
Power Zoom (besides the 30:1 digital zoom); Flying erase head for editing;
|
|
self-timer recording: digital electronic image stabilizer that's needed for
|
|
long-range zoom recording, and needed for automobile use when on the move
|
|
or in moving surveillance: a High Speed shutter; and a carrying case.
|
|
|
|
Also available for the PV760 is a four-piece electronic mike. It consists
|
|
of two microphones: One is a pen mike; one is a concealable bow tie mike.
|
|
The receiver slides on to the camcorder to plug the sound into the camcord-
|
|
er as you tape the action. Another receiver can be attached to your belt,
|
|
or on another person who needs to hear what's going on -- or going down.
|
|
|
|
Update: Seen in a (1992) VIDEO BUYERS GUIDE. A $1,200 Hitachi VM-E25A 8mm
|
|
camcorder with a 1:8 normal Zoom plus digital Zoom that boosts it by a
|
|
factor of 8 to obtain 64 Zoom.
|
|
|
|
The VM-E25A is very small, lightweight, easily fits in one hand, and has
|
|
all kinds of options and accessories as standard, plus optional equipment.
|
|
For surveillance work, you can replace the standard (removable) lens with a
|
|
5X telephoto and/or wide angle lens.
|
|
|
|
The camera lens gives clearer pictures than the (electronic) digital zoom
|
|
(although the digital zoom is clear enough until you get around 32 power).
|
|
At 64 digital Zoom, the pictures get fuzzy. By changing the lens to (say) 5
|
|
power, you then have a 5:40 regular Zoom via lens, for clearer pictures,
|
|
plus digital Zoom multiplying that to about 300 power for longer range.
|
|
|
|
Some camcorders, like the Panasonic 660, ($948) which has a 1:12 Zoom plus
|
|
digital Zoom cranks it up to 96 Zoom. Add a 5 power telephoto lens and you
|
|
can get (theoretically) up to 480 magnification.
|
|
|
|
At strong magnification, you need a solid rest or tripod to eliminate the
|
|
small quivering of hand movement which is also magnified in proportion to
|
|
the Zoom factor. An image stabilizer feature would be a must for this kind
|
|
of long distance recording.
|
|
|
|
Lux, or Candle Light
|
|
|
|
All camcorders are rated with a lux designation. One lux is equivalent to
|
|
one candle power. Theoretically, a one lux camera can take a picture when
|
|
there is a brightness of one candle one foot away lighting the object.
|
|
Manufacturer's claims are not always the same as performance. Aside from
|
|
that comment, you can use the lux rating of a camera as a pretty good
|
|
indicator of its ability to make a reasonably clear picture under less
|
|
than perfect light.
|
|
|
|
For undercover work, a one- or two-lux rated camera is best. It will
|
|
perform better than a seven lux camera -- all things considered, but not
|
|
always equal. The lens has a lot to do with picture clarity: a camcorder
|
|
with a good quality lens and rated four lux may provide better picture
|
|
quality than a camcorder rated two lux but has poor quality lens. If you
|
|
can, lease a couple of cameras for a day or two and compare results. Try
|
|
before you buy, or try to get a money-back option.
|
|
|
|
Zoom Lens and Telephoto Adapters
|
|
|
|
The next important requirement of a camcorder for a CrimeFighter is to take
|
|
pictures at a distance. Most cameras have a zoom lens. Some models have at
|
|
least six-to-one zoom, but newer models have 12-to-one, variable-power
|
|
zoom. Digital zoom (microcomputer technology) increases the lens zoom by a
|
|
factor of 8. A 1:12 zoom with digital = 64, a 12;1 lens zoom with digital
|
|
zoom = 96.
|
|
|
|
In addition, you can add telephoto lens from 1.5 to 5 power, plus wide-
|
|
angle lens to increase the magnification and field of view. A 12:1 lens
|
|
zoom, with a 5 X telephoto lens makes it 60:1. Add digital zoom of 8 power
|
|
to get (theoretically) 60:480 zoom. Of course, you'd have to have a steady
|
|
mount to suppress the small movement of shaking hands which would also be
|
|
multiplied. However, some cameras have a "stabilizer" that acts like a
|
|
ship's gyroscope to suppress rolling and dipping. It's computer controlled
|
|
"fuzzy logic" (artificial intelligence software). As the years go by, more
|
|
and more improvements will be made on high tech equipment. Always ask.
|
|
|
|
Telephoto lens vary in cost from about $60 to $300 each. The thing to watch
|
|
out for when buying a camera is whether or not the lens cover lip (or no
|
|
lip) on the camera will prevent you from attaching telephoto lens to the
|
|
camera. Ask knowledgeable store clerks and browse through Camcorder mag-
|
|
azines in supermarket magazine racks for information on where to purchase
|
|
cameras and accessories.
|
|
Focus System
|
|
|
|
The ability to focus through window glass is important because lots of
|
|
movies will be made through closed car windows. Focusing systems that use
|
|
any form of sonar or infrared to "find" the subject will be bounced off
|
|
the glass. That makes it difficult to use for covert surveillance work.
|
|
Opening the window may not always be possible. Be sure to get a camera
|
|
that has a manual focusing override control. (The EVC-X10 has a manual
|
|
override control.) Through-the-lens (TTL) viewfinders are recommended for
|
|
through window glass (inside-outside) surveillance. Talk to your local
|
|
sales representative for specific information.
|
|
|
|
Sound
|
|
|
|
Wiretapping is illegal, but not if you are making a recording of a crime in
|
|
progress or recording a conversation of persons who consent to its being
|
|
made for their own protection. With that in mind, external microphone jacks
|
|
on a camcorder are a necessity. Most have them, but look for that feature.
|
|
|
|
There's a "CamEar" (Camera Ear) that provides an audio zoom for video
|
|
camcorders. (about $70 from Silver Creek Industries, 1-800-533-3277.)
|
|
Quite a few other zoom and wireless microphones for long distance pickup
|
|
range in price from $40 to $250. Contact: AZDEN, 147 New Hyde Park Road,
|
|
Franklin Square, N.Y. 11010, phone # (516) 328-7500.
|
|
|
|
Time and Date
|
|
|
|
This is usually a standard feature, but look for it, because it may be
|
|
important to date-stamp the time and day when the tape was made.
|
|
|
|
Instructions on How to Buy and Use a Camcorder
|
|
|
|
Video tapes on "How to Make Video Tapes" and books on this subject can be
|
|
found in the advertising pages of most Camcorder magazines. Here's a few
|
|
books to get you started: "The Video Camcorder Handbook -- How to Select
|
|
and Use a Camcorder -- Any Brand or Format" ($14.95), and a companion book,
|
|
"Pro Techniques of Making Home Video Movies" ($12.95), "How to Understand
|
|
the Multitude of Video Products" ($12.95) and "Basic Instruction on Making
|
|
Home Video Movies" ($9.85). Many video stores have video catalogs to locate
|
|
any video you want to special order. Ask them for a rental/purchase option.
|
|
|
|
Financing Hardware
|
|
|
|
Radio Shack had a $788 special on camcorders recently. It offered their
|
|
Model 126 MovieCorder, a VHS, two-lux, 12-power variable zoom camera. It
|
|
has manual focus override, time and date stamp, and a 12 volt input jack to
|
|
run off a vehicle's batteries for long-term surveillance work. The sale
|
|
will be over by the time you read this, but, with the Shack, you can expect
|
|
there will (probably) be repeat sales in the future. If you don't have the
|
|
cash, you can buy it on time payments at $25 per month. If you can't afford
|
|
the expensive models, this one or a similar one may be sufficient. Radio
|
|
Shack's hand-held cellular phone, model CT-1033, has 3 watts of power for
|
|
maximum output. It's also available on time payments for $15 a month. So,
|
|
for about $40 a month you can get the two most important pieces of equip-
|
|
ment from a local Radio Shack store.
|
|
|
|
Electronic Surveillance Equipment
|
|
|
|
Be advised that unless you have legal authorization for a wiretap, using
|
|
such equipment to eavesdrop is illegal. Two exceptions: when you record a
|
|
conversation with permission from one of the parties of the conversation
|
|
being recorded. The other exception is when a criminal action is observed.
|
|
Recording the incriminating conversation between criminals actually
|
|
committing a crime is not a violation of an innocent person's civil rights.
|
|
|
|
When you're working on a case with law enforcement officials, wiretap
|
|
authorization may be obtained. If so, the appropriate equipment may also
|
|
be available. However, if their surveillance equipment is old, worn out,
|
|
or obsolete, a CrimeFighter may prefer to use personal electronic equipment
|
|
to get reliable results. In that case, you may want to know what's
|
|
available and where to get it. Instead of trying to include and describe
|
|
the hundreds of devices and miscellaneous equipment that's mentioned in
|
|
many catalogs, I'll just refer you to the catalogs and where to get them.
|
|
Most are free, but a few require two or three dollars to pay for the
|
|
printing and mailing. (Send a couple of bucks with your mail request.)

1. Sherwood Communications Associates, Ltd., 1310 Industrial Highway,
|
|
Southampton, Pennsylvania 18966 (215) 357-9065. This company sells quite
|
|
a few camcorder models, including the SONY EVC-X7 and X10, plus attachments
|
|
and disguises for camcorders used in undercover surveillance. They have a
|
|
separate catalog of wiretap equipment and various gizmos and gadgets, plus
|
|
an extensive library of unusual books on various subjects. The company was
|
|
founded by Security Professionals and is recognized as one of the leading
|
|
distributors of electronic security and communications systems.
|
|
|
|
2. CRB Research Books, Inc., P.O. Box 56, Commack, N.Y. 11725, (no phone
|
|
number given) has a catalog ($1) that seems to specialize on books and
|
|
equipment on radio frequency registries, hand held (cellular phone)
|
|
scanners and other types of communication monitoring, CB radio, clandestine
|
|
operations, cryptography, electronic surveillance, countermeasures,

espionage, and computer hacking.
|
|
|
|
3. Protector, P.O. Box 520294, Salt Lake City, Utah 84152 (801) 487-3823
|
|
has a catalog of surveillance equipment, including miniature video cameras,
|
|
audio jamming equipment, voice scramblers for phones, and quite a bit more.
|
|
|
|
4. Armo-Tech, P.O. Box 276524, Sacramento, California 95827 (916) 369-7139
|
|
doesn't have a catalog, as such, but they do have hi-performance body armor
|
|
made of light-weight Kevlar. Their vest, front or back ($190) or full wrap
|
|
around coverage ($230), will (so they say) defeat a .45, .357, 00 buckshot,
|
|
and 9mm handgun rounds. If you think you might need one, ask for their
|
|
literature and current prices.
|
|
|
|
5. XANDI Electronics, Box 25647, Tempe, Arizona 85285 -5647, has a mini-
|
|
catalog of miniature radio transmitter/receivers (bugs) and bug detectors,
|
|
telephone "snoops", telephone recorders, vehicle tracking transmitters, and
|
|
voice disguisers. If you're into hi-tech electronics, printed circuit
|
|
boards and electronic kits are available to make your own. They also have
|
|
assembled and tested units for the not-so-handy.
|
|
|
|
The disclaimer in XANDI's catalog is typical of catalogs containing
|
|
illegal-to-use equipment or technical information on locks picks or how to
|
|
pick locks, making silencers, bombs, etc. It's worth mentioning at this
|
|
point. A typical disclaimer is as follows:
|
|
|
|
"The products listed in this catalog are intended to be educational only.
|
|
They are aimed at the electronic hobbyist. Some of these products might be
|
|
used in situations that are illegal depending on State and Federal law.
|
|
XYX Company assumes no responsibility for the illegal use of its products
|
|
and, in fact, strongly recommends against the illegal use of any electronic
|
|
device. You, as the purchaser and user, assume all legal and financial
|
|
responsibility which results from the ultimate use of your purchase."

Remember, the possession of illegal wiretap equipment or burglar tools is a
|
|
felony in most States. If you purchase any such items, don't get caught
|
|
using them or having them in your possession outside of your home under
|
|
"suspicious circumstances" unless you have a warrant or police approval.
|
|
(And get it in writing.).

|
(Feedback from readers who have these camcorders and related equipment will
|
|
be appreciated. I'd also like to hear from vendors of this equipment, who
|
|
may provide CrimeFighters with suitable discounts. I'll add your comments
|
|
and suggestions to the next version of this Crimefighter book.)
