Study Material Flashcards
Prepare for exam
Certification
- good for 3 years
- Free upgrade online to renew for 3 additional years
- Better discounts
- Certification stays with you, not with company
Lightfinder
- Low light situations
- Produces colour image in low light
- Does NOT go into IR Black/white mode
- Scene cannot be pitch black
- Camera can be manually set for low light, but Lightfinder works automatically with minimal/no side effects
- Lens must be good enough
- Processor heavy
WDR
- (Wide Dynamic Range) Forensic Capture
- Bright and dark areas become visible (Balanced)
- “opposite of Lightfinder”
- Balances the light source between dark and light areas
- Takes multiple exposures. Puts over and under exposed images together
- Dark areas are over exposed to brighten upgrade
- Light areas are under exposed to not be blown out
- Do not use if you require high frame rate (Ex. 60FPS)
- By default is on for supported cameras
- Halo appears around objects where there is high contrast between light and dark areas
- Dynamic contrast and dynamic capture both used as part of the Forensic Capture
Optimized IR
- Illumination automatically adapts to camera zoom level
- Most LED illuminators on a camera is 4
- Too many LEDs heat up the sensor and burn it up
- Produces better balanced IR instead of a focused illumination beam
- Lights are dimmed or brightened based on object distance from camera (less light for close up, more for far away)
EIS
- (Electronic Image Stabilization)
- Where cameras are shaky or vibrating
- Ideal for pole cameras in windy areas
- Not all PTZ cameras have EIS, though majority do
4K
- Benefit of 4K = Captures more detail, better digital zoom capability, cover more area with single camera (or less)
- Much higher bandwidth and storage consumption
- Light gathering capability is worse than lower resolution cameras 1080/720
- Now supports Lightfinder
- Large area coverage
Corridor Format
- Takes 16:9 and flips it 90 degrees to make it 9:16 for longer view
- 2 Ways to do Corridor format. Auto flip - Physically flip camera and it will be detected and adjusted. Manual flip - requires software change to adjust view 90 degrees
- NOT the same as rotating in VMS
Zipstream
- Compression algorithm
- Saves on bandwidth and storage consumption
- Diff from H.264 is that when there is no change in scene (larger savings with Zipstream)
- H.264 with zipstream performs better than H.265
- H.265 is not yet available because it’s not industry supported (encoders etc…)
Multi-view streaming
- Ability to take single camera and break it out to multiple separate “streams” or views
- 4K cameras support multi-view
- “De-warping” 360 degree cameras into multi-view
- 360 degree cameras can be mounted on the ceiling or wall
Footprints
- Mini dome
- Box
- Multisensor
- Network Horn
- PTZ
- Door Station
- Door controller
- Divided
- Network Radar
- Bullet
- Positioning Camera
Why so many camera models?
- Environment
- Form-factor
- Features
- Budget
Fixed cameras
- Indoor, Outdoor, Integrated
- Ability to change lens is a huge benefit
- Outdoor = indoor + housing
- Integrated = indoors or outdoors but is an all in one package (can’t change lens or housing)
Dome Network Cameras
- Cannot change the lens
- Good for multisensor (1 network camera for 2-4+ sensors)
- Discreet
- Vandal-resistant
Pan Tilt Zoom Cameras (PTZ)
-Zoom in, zoom out, pan left/right/up/down
Q61 series PTZ
- Comes with sharp dome
- KNOW SHARP DOME
- Sharp dome can see 20 degrees above horizon
- Ideal for uneven terrain
- Speed Dry = Shakes camera to get water off camera
Artic Temp Control
- Cold startup (-45c)
- Will not allow PTZ self check below -45 to protect moving parts
- Camera will pre-heat itself until it is safe to use PTZ (move frozen parts)
-C Models
(High Temp Control)
- Cooling enclosure
- Forces hot air out of the chamber
- No air flow between separate chambers, only heat transfer
- Can operate up to 167F/75C
Stainless Steel PTZ
-Resists corrosion of harsh environments
Explosion protected
- Sparks will not exit chamber/housing
- Will not cause explosion
Thermal (models, use case/conditions)
- Works with no light
- Use for detection, not for identification
- Q19 or Q29 are thermal cameras. No physical identifiers.
- Q29 has temperature alarm ability. Set threshold and if object is too hot or too cold an alarm will alert
- Server rooms, transformers, hospitals are ideal for temperature readings
- Thermal able to detect through smoke and fog
- Thermal cannot see through glass
- Moisture in the air can affect thermal views (needs contrast of heat)
- Less false triggers from thermal vs regular camera
- Thermal lenses are made from Germanium since thermal sensor cannot penetrate glass
Door controller (Power/ how many doors?)
- Controls 2 doors
- PoE
Intercom (Communication/ protocol?)
- 2 way communication
- SIP enabled, VOIP can be used
Network speakers (protocol)
-SIP enabled, VOIP can be used
Axis Free VMS up to 16 devices
(Companion app)
-Can configure whole thing with mobile app
Axis VMS (paid full software suite)
Camera Station
-Small to medium sized deployment
F series
- Modular
- Covert
- Use in vehicles or areas where cameras needs to be hidden
