Blue Book Chapter 5 Flashcards
what communication protocol is used by most computer networks
TCP/IP
how are inputs and outputs on a camera used
allow network transmitters to send signals to other locations over the network
allow transmitter to receive control signals from remote locations
can control auxiliary devices (EG motion detection, speakers)
How does a NVR receive its images
through a network connection
it can be a ethernet network or internet
who assigns the IP address to a device
network manager
POE
power over ethernet
RAID viewing or tampering
redundant array of independent disks
another name for network transmitter is a
video server
what is the main difference between a standard DVR and a hybrid DVR
a DVR only has the ability to record a digital signal while a HDVR has the ability to record digital and analog signals
SAN (acronym meaning)
storage area network
NVR
network video recorder
What is the process for viewing network video on a computer
type the IP address into a web browser
what do you do if the existing network does not have sufficient bandwidth to support the addition of network video
install a parallel network
what affects can be expected if the network video equipment consumes too much of the available network bandwidth

How does network video differ from standard CCTV
standard video systems are hardwired to a image store/management system while network video systems connect to the network hub and can be viewed by multiple devices
how are devices protected to prevent unauthorized
a password and User ID
the RAID array connects directly to the ______ to increase the amount of video storage
NVR/HVR
what is the benefit for powering cameras via POE
one cable
what at the two memory types network cameras use to store images locally
built in or via memory card
What makes a camera a “network Camera”?
it has an ethernet connection and a NIC
What is a SAN
a whole network set up solely to store data
Can devices share an IP address
no, it would confuse the system
why would you connect a RAID array to a HVR
to increase the amount of video storage
what type of additional storage would you recommend to a customer that insists on a very large storage reuqirement with expansion capabilities in the future
SAN - Storage area network
