Axis networking certification
Exam/147 Answered Questions
Secure transmission of data protocol, sender pings receiver, to make sure all
data was received. - - TCP/IP
- Temperature contrast in the scene - - When considering a thermal camera,
what factors should one consider?
- Lens that has adjustable focal length, however needs to be manually
refocused after change - - Varifocal lens
- Time of light - - Laser Focus
- Whens lens format is smaller then sensor format - - Vignetting
- Measure of resistance to dust, and water (Order is important) Ik66 is the
base for most axis cameras, but important to remember that ik66 is the most
common. Actual format is solids, then liquids but we are measuring for dust
and water - - IP rating
- The P frames get larger. - - Why does movement cause bit-rate to
increase?
- Proprietary method in which Axis decreases bandwidth usage, without
sacrificing quality or dropping frames. Important to note that only h.254 and
h.256 are zip stream compatible, MJPEG is not - - Zip Stream
- Rating of which a device can withstand mechanical impacts. Anything
under IK06 is very fragile - - IK Rating
- Method in which Panoramic cameras can give you a good picture using
multiple sensors - - Dewarping
- Smog, temperature contrast, and weather or fog - - Deterrent of a Thermal
camera
- Axis Camera Station - - ACS
- Any camera setting in each individual camera can be pulled and made into
a VAPIX command in ACS. (Axis Camera station) - - VAPIX Commands in ACS
- Proprietary commands from Axis. Essentially their version of MACROS. It is
comprised of 4 parts, in order:
, Ip address of device, dir (file directory of where target file is located),
Argument (essentially what am i asking for?) and Value (The end result of
what I am asking for, so for example if the Argument was "resolution" my
Value would be "1920x1080" - - VAPIX
- Session Initiation Protocol: Basically it does what an old call operator would
do, it starts and makes the connection with the end person/thing. Then once
the connection is made, it steps away. Once the conversation is done, SIP
once again will come back and close the connection on both ends - - SIP
- Essentially this protocol established what sound and video codec you are
going to be using during the call. For example, if you are making a video call,
using h.254 and codec G.726 for voice, it will make sure that the that is the
same on the other end of the connection. Same applies if you are using
h.256 and AAC codec. IT knows that you are broadcasting a high resolution
high quality music - - RTP (Real-time Transport Protocol)
- AXIS tampering is triggered the camera has been disturbed or detects that
is no longer looking at once it was looking at before. Thus it waits 15secs,
before automatically starting to refocus and make sure that the scene it is
looking at is in focus - - Tampering Alarm
- Measure of visible light in an area - - LUX
- Half the distant to light, multiple by 4, double your distant away, divide by
4. - - Inverse formula of lux
- Nas and SD card - - Supported storage or Edge Storage?
- 1920x1080p Industry standard for HD - - HDTV Resolution
- Is determined by sensors size and focal length - - Field of View
- FPT cable is shielded Catx cable, protects against EMI. Can also be run
longer then UTP cable - - Axis recommends FTP Cable why?
- unshielded twisted-pair cable - - UTP Cable
- Shielded Twisted-pair cable - - FPT
- File Transfer Protocol - - STP
- Network address translates private IP's to a Public IP - - NAT
