ANVE Practice Questions

A.  

Is not recommended, since bandwidth demands from the surveillance video would likely congest the network.

B.  

Will benefit from using VLANs, to keep the surveillance video separate from other network traffic, reducing the risk for network congestion.

C.  

Will cause unacceptable video latency, due to the amount of UDP traffic taking precedence on the network.

D.  

Will benefit from establishing VPN connections to the cameras, reducing the risk of malicious users eavesdropping on the video.

A.  

Identifying people in complete darkness

B.  

Detecting motion only at nighttime

C.  

Measuring exact temperatures in daytime

D.  

Detecting activity in daylight and complete darkness

A.  

Makes it possible to adjust the focal length like a zoom lens, but requires refocusing after adjusting the focal length.

B.  

Allows the depth of field to be adjusted, making it possible to blur out the background for privacy protection or reducing distraction.

C.  

Can rapidly change focus between a set of predefined positions, making it easy to move between different points of interest in the scene.

D.  

Is a lens where the focus can be adjusted, as opposed to a fixed focus lens, making it possible to focus on objects close to the camera.

A.  

There is more energy in D

C.  

B.  

It is easier to back-up DC with battery.

C.  

There is less power loss in cables with D

C.  

D.  

There is less risk for surge with D

C.  

A.  

PoE

B.  

Processing speed

C.  

IR light

D.  

Interlaced scanning

A.  

Install more low-priced cameras to cover the complete site.

B.  

Make sure each camera is seen by at least one other camera.

C.  

Use PoE, and not a PoE splitter.

D.  

Install thermal cameras.

A.  

60 fps

B.  

1080pHD resolution

C.  

160 dB dynamic range

D.  

Face recognition at 70 m (230 ft)

A.  

It gives the encoded video a higher frame rate compared to the analog input video

B.  

It reduces the tearing effects when there is movement between two fields in one frame

C.  

It enhances the dynamic range between two fields in one frame

D.  

It decreases the bandwidth needed to transmit the compressed video

A.  

PTZ should not be used with IR light

B.  

The f-stop value of a lens will get higher if you zoom in

C.  

PTZ cameras in general tend to have lower f-stop value compared to fixed cameras

D.  

PTZ cameras should not be used with mixed IR and white light

A.  

650 nm

B.  

750 nm

C.  

850 nm

D.  

940 nm
