for.storage,.and.the.quality.of.the.video.also.increased.as.the.
technology.evolved.and.improved.over.time.
Another.big.change,.besides.quality,.has.been.the.incor-
poration.of.wireless.technology.to.allow.for.the.deployment.
of.these.devices.in.more.places.and.without.the.need.to.hide.
cabling.to.make.them.more.discreet.
Video.surveillance.cameras.can.be.a.simple.ixed.device.in.
the.corner.of.a.room,.a.high-end.movable,.zoomable.device.
overlooking.a.large.area,.or.even.tiny,.barely.noticeable.“pin-
hole”.cameras.used.for.gathering.intelligence.without.anyone.
being.able.to.see.them.
In. all. cases. they. work. in. a. similar. fashion. for. our. pur-
poses..They.are.controlled.either.by.an.automated.program.
or.by.a.human.controller.(or.both),.and.the.data.they.record.
are.stored.for.varying.amounts.of.time.depending.on.the.stor-
age. capacity. and. the. retention. laws. or. regulations. for. the.
organization.capturing.them.
As.an.example,.a.bank.will.have.regulations.from.inancial.
laws.as.to.how.long.it.must.keep.video.records.of.daily.activi-
ties.. They. will. also. probably. have. organizational. rules. that.
dictate. how. long. those. records. are. preserved.. To. that. end,.
they.will.be.required.to.purchase.or.arrange.for.enough.stor-
age.capacity.to.serve.those.needs.
Digital.video,.especially.at.the.higher.quality.with.which.
it.is.currently.captured,.can.take.up.a.great.deal.of.storage.
space..A.high-deinition.video.ile.of.approximately.10.min-
utes.length.will.use.approximately.3.gigabytes.or.more,.so.
imagine.how.much.data.storage.you.would.need.to.preserve.
a. workday's. worth. of. video. data.. If. you. do. the. math,. you.
realize.that.we.are.looking.at.close.to.150.GB.for.an.8-hour.
day,.and.because.most.organizations.are.likely.to.record.at.
least.10.to.12.hours.daily,.it.will.be.closer.to.200.GB.a.day..
If. they. are. recording. 24. hours. a. day,. it. would. be. at. least.
twice.that.
We.said.earlier.that.storage.is.getting.less.expensive.and.
larger.all.the.time,.but.it.still.is.not.free..So,.even.assuming.
you.have.a.very.large.data.store.of.say.50.terabytes,.if.you.are.
