Alarm Actions The.assigned.responses.for.the.dome.camera.when.inputs.change.from.normal.to.abnormal.states.
The.dome.may.run.a.Preset,.Pattern,.or.have.no.assigned.action.for.each.of.the.four.dome.inputs..The.dome.may.also.send.alarm.
states.to.the.host.controller.for.processing..See.also.Input.and.Normal.Input.State.
Areas Programmed.start.and.end.points.of.the.dome’s.field.of.view.around.its.pan.axis..
Each.area.is.a.part.of.a.circular.viewing.area.that.extends.around.the.dome..The.areas.can.be.different.sizes..Up.to.6.areas.can.be.
programmed.for.the.dome.
Automatic Gain
Control (AGC) Allows.for.the.amplification.of.the.video.signal.in.scenes.with.minimal.ambient.light..Many.low-light.scenes.result.in.picture.noise...
As.gain.is.increased,.the.picture.noise.is.also.amplified..When.AGC.is.enabled,.the.value.of.the.gain.setting.is.based.on.feedback.from.
the.camera..When.AGC.is.disabled,.the.camera.uses.the.value.set.for.the.manual.gain.setting..The.trade-off.between.picture.level.and.
noise.may.be.adjusted.when.AGC.is.disabled.
On-screen Menu
The.text.overlay.menu.system.used.for.setting.dome.features..The.utility.is.accessed.using.a.keystroke.combination...
The.utility.provides.settings.for.camera.functions,.zoom,.alarms,.text.display,.and.password.protection.
Flip Allows.the.dome.to.automatically.turn.80.degrees.when.the.camera.tilts.to.its.lower.limit.and.stays.in.that.position.for.a.brief.delay..
When.the.dome.flips.(rotates),.the.camera.starts.moving.upward.as.long.as.the.tilt.control.is.kept.in.the.down.position..Once.the.
Joystick.handle.is.released.to.neutral.position,.the.tilt.control.returns.to.its.normal.operational.mode..The.flip.feature.is.useful.when.
you.need.to.track.someone.who.walks.directly.beneath.of.the.dome.and.continues.on.the.other.side.
Home Position
The.default.position.to.which.the.dome.camera.returns.after.an.assigned.period.of.inactivity.passes...
The.default.position.may.be.a.Preset,.Tour,.Pattern,.or.No.Action.
Input Alarm A.connection.point.on.the.dome.camera.that.enables.the.system.to.monitor.Input.Devices...
There.are.four.inputs.available.for.the.dome.camera.
Input Devices
External.devices.that.provide.information.about.the.condition.of.system.components.that.connect.to.the.inputs.on.the.dome.camera..
Typical.input.devices.include.door.contacts,.motion.detectors.and.smoke.detectors.
IR Mode
A.feature.of.the.camera.that.permits.manual.or.automatic.switching.between.colour.and.IR.(black-and-white).operation...
When.IR.mode.is.active,.clearer.images.may.be.obtained.under.low-light.conditions.
Line Lock Allows.you.to.phase.lock.the.video.with.the.AC.power.line..When.line.lock.is.enabled,.it.prevents.vertical.video.rolling.when.switching.
multiple.cameras.to.a.single.monitor..If.text.appears.slightly.tinted.on.colour.monitors,.disabling.the.line.lock.may.prevent.this.problem.
name Information
Relates.to.the.display.the.dome.name,.the.area.where.the.dome.is.pointing,.the.name.of.the.preset.or.pattern.that.is.running,.and.
alarm.names..The.display.of.each.type.of.name.setting.can.be.enabled.or.disabled..When.the.display.of.camera.or.area.title.(name).is.
enabled,.the.information.appears.on.the.screen.continuously..Preset,.tour.and.pattern.titles.(names).appear.only.while.they.are.active.
normal Input State
Describes.the.expected.state.of.a.device.connected.to.one.of.eight.dome.camera’s.inputs..The.normal.state.may.be.open.or.closed..
When.a.device.is.not.in.its.normal.input.state,.an.alarm.is.issued..
north Position User-definable.setting.that.may.correspond.to.magnetic.north.or.some.well-known.landmark.
Used.to.approximate.the.camera.dome's.pointing.direction.when.Direction.Indicators.are.enabled.
Low Shutter
Setting.used.to.improve.the.quality.of.video.obtained.in.extreme.low-light.situations..When.the.Low.Shutter.setting.is.enabled,.low-
light.information.is.collected.over.multiple.fields.based.on.the.Shutter.Limit.setting..As.a.result,.video.may.appear.blurred.or.choppy.
in.extreme.low-light.situations..This.setting.does.not.effect.camera.operation.in.normal.lighting.situations...
See.also.Automatic.Gain.Control.(AGC).
Pattern A.series.of.pan,.tilt,.zoom.and.focus.movements.from.a.single.programmable.dome..Up.to.8.patterns.may.be.programmed.for.the.
dome.camera.
Preset
Programmed.video.scene,.based.on.a.specific.pan,.tilt,.zoom,.and.focus.settings..Up.to.40.presets.may.be.programmed.for.the.
dome.camera.
Privacy Zones Masked.areas.of.the.dome.camera's.viewing.area..These.masks.prevent.operators.of.the.surveillance.system.from.viewing.these.
designated.zones..The.Privacy.Zones.move.in.relation.to.the.dome.camera’s.pan/tilt.position..In.addition,.the.apparent.size.of.the.
Privacy.Zone.adjusts.automatically.as.the.lens.zooms.in.or.out..Up.to.eight.Privacy.Zones.may.be.established.for.a.dome.camera.
Shutter Limit Setting.used.to.define.the.maximum.exposure.time.for.the.Open.Shutter.setting..The.values.for.the.setting.range.from./.to./60..
The.default.setting.is./4.
Vector Scan
Move.from.start.point.to.end.point.including.tilt.and.zoom.simultaneously.and.linearly.
wDR Wide.Dynamic.Range.Technology.uses.two.shutter.speeds.in.alternative.video.fields-high.and.normal-.every.60th.(or.50th).of.a.
second.and.combines.two.fields.into.one.progressive.scan.frame..It.allows.every.detail.to.be.captured.accurately.even.if.one.portion.
of.an.image.is.brillantly..Whether.at.the.high.shutter.speed.or.normal.shutter.speed,.the.progressive.scan.CCD.provides.a.horizontal.
resolution.of.470.lines..As.a.result,.combined.fields.yield.a.frame.of.high-quality.images.
white balance Adjustments.in.the.colour.hue.(red.and.blue).gains.for.a.camera.so.that.true.white.appears.white.in.the.image..It.is.normally.com-
pensated.for.by.the.automatic.gain.control..In.some.lighting.conditions,.you.may.need.to.manually.adjust.the.red.and.blue.settings.
for.optimal.viewing..When.Automatic.White.Balance.is.enabled,.the.camera.measures.the.image.and.automatically.adjusts.the.red.
and.blue.settings.to.balance.white..When.Automatic.White.Balance.is.disabled,.the.camera.uses.the.values.set.for.the.red.and.blue.
settings.to.balance.white.
