For this situation,

install high-resolution,

varifocal cameras.

Varifocal cameras

have adjustable lenses

that allow you to get

exactly the picture you

want—zoom in to get

a tight image with lots

of detail, or zoom out

for a wide overview.

Illuminate the area

well, but never point

a camera directly at a

light source.

Entrance

If your storefront is made

of glass, the lighting will

change over the course of

the day. Most cameras will

show you a completely

washed-out picture. If this

happens to you, you need

a Wide Dynamic Range

(WDR) camera, which lets

you view the very dark and

very bright parts of the

picture simultaneously.

Typical Retail Setup

Selecting the best components is the hardest part of

setting up a surveillance system. Not every camera

will work for every application. At B&H, we can

help you  nd the right cameras for your speci c

needs, without breaking the bank. Here, we’ll look

at a common purpose for surveillance equipment:

minding the shop when you can’t be around.

VIDEO AT A GLANCE

GETTING STARTED A CCTV (Closed Circuit Television) system consists

of a camera and monitor. Choose your wire (see the “UTP or Coax” box,

opposite) and connect these components. Plug the camera into a power

supply. Congratulations! You’ve just built a CCTV system.

WHAT IF YOU CAN’T ALWAYS WATCH THE CAMERAS? You’ll need to

record the video stream from the cameras. In the past, special VCR’s with

time-lapse capability were popular. You’d program them to record so many

pictures (or frames) per minute; a lower frame rate allowed more video to  t

onto a single VHS tape. Otherwise, recording to VHS tape could get expen-

sive quickly.  e trade-o was that more compressed video rendered fewer

details, because only a few pictures per minute were recorded. VCR’s only

recorded one channel of video, too. For multiple cameras, you’d have to con-

nect the VCR to a “mux,” or multiplexer, splitting the screen into 4, 9, or 16

segments, one for each camera. Picture detail was almost imperceptible.

ENTER DVRS Digital Video Recorders (DVRs) were a huge step forward.

 ese are essentially computers that record video to hard drives. Hard

drives cost much less than their equivalent in VHS tape, and DVRs can also

record multiple cameras. Video storage used to be measured in hours; it’s

now measured in days, weeks—even months. DVRs use video data proces-

sors to compress the video, cramming more video into the same amount of

space, storing higher and higher frame rates (FPS or frames per second). 24

FPS is reckoned as “real time.” Even 12 FPS seems close to real time. Many

security pros use 7.5 FPS as the standard recording rate. Many DVR’s have IP

connections as well, allowing Internet connectivity via a PC and a router. As

of this writing, Mac-compatible DVR’s are rare.

THE CAMERAS Choose the right camera. Will it always be dark? Will you

need a camera to enhance available light? Outdoor cameras should have

infrared illuminators to allow night vision. Will part of the picture be very

brightly lit and partly dark? A camera with Wide Dynamic Range (WDR) and

dual shutter speeds will take each zone of the picture and expose it properly,

allowing you to see a complete image of bright and dark areas.

FIXED VS. PTZ PTZ (Pan Tilt Zoom) cameras allow you to move the camera

remotely until it’s oriented correctly, and to zoom precisely.  ese individual

cameras are expensive—the price of four or  ve  xed cameras, typically—so

only install a PTZ to cover large, open areas such as parking lots or lobbies.

LONG-TERM ARCHIVING Backing up your data is always a safe bet. Hav-

ing a great deal of hard-drive space installed on the DVR is a good idea,

because you can search for video from the DVR control program. On the

other hand, this can become expensive. Another option: back up video to

an external hard drive. You will not be able to search using the DVR’s search

 lters, but the data will be protected in case anything destroys the DVR,

such as theft,  ood,  re, or electrical surges.

A WORD ABOUT PRIVACY Before installing CCTV, check the local laws

regarding privacy and recording. Never install video or audio surveillance

anywhere there is a reasonable expectation of privacy, such as in bath-

rooms, locker rooms, changing rooms, medical examination rooms, etc.

Never record another person’s private property without permission.

Security is a huge concern for today’s

home and small business owner. With such

a bewildering number of system options

available, B&H can help you ﬁ nd the perfect

solution to ﬁ t your needs and budget.
