Preparing Your Network Video Project; Main Considerations - Axis 31922 Product Manual

PREPARING YOUR NETWORK VIDEO PROJECT

Main considerations

1. Define the scene and type of network video products required
> Scene: What kind of scene do you want to
monitor? How important is it?
This will help you determine the features you would
like to have in a network camera, such as video
quality, light sensitivity and type of lens.
> Lighting conditions: level of indoor and/or out-
door light sensitivity required.
Axis offers network cameras for indoor use, as well
as models for both indoor/outdoor conditions. In-
door/outdoor cameras have varifocal lens that au-
tomatically adjust the lens' iris. Day/night cameras,
which provide color images during daytime and
black and white images during night time are also
available.
Check details on the network camera's light sensi-
tivity both in indoor and/or outdoor environments.
Lighting conditions are measured in "lux".
2. Determine your application needs:
features, recording and storage needs
> Application: Simple remote viewing, intelligent
surveillance system with advanced event manage-
ment, input/output triggers, audio?
> Viewing and recording needs: Determine when
and how often you need to view and record: day,
night and/or weekends? Schedule the needs for
every scene.
> Calculate storage requirements.
> Calculate bandwidth requirements.
Preparing your network video project / TECHNICAL CORNER
> Distance from position of camera to object
being monitored.
This determines the type of camera and type of lens
(normal, telephoto, wide-angle) to use, as well as
the placement of the camera(s). Choose Axis net-
work cameras with fixed focal or varifocal lenses,
with or without replaceable lenses, according to the
level of flexibility needed.
> Angle of view needed: wide, narrow, general or
detailed coverage (Determine how much of the
scene you need to see).
Network cameras come with fixed angle and focus,
as well as variable ones that allow remote pan/tilt/
zoom capability, which enables a wider area of cov-
erage.
> High or low traffic.
The higher the traffic, the more cameras may be
needed.
3. Determine your network needs
(LAN/WAN, wireless)
> Assess network use of current LAN: what are you or
the company using it for?
> Assess network use of current WAN links.
> Determine the pattern of congestion levels over a
given period.
> Do you need to add new equipment to the network,
e.g. switches, or use existing infrastructure and
equipment?
> Do you need to subscribe to additional ISPs for
redundancy?
> Do you need to subscribe to additional ISPs for
redundancy?
