Frequently Asked Questions

Q: Can I use the USB or SD Memory slots to offload video?
A:
No, these ports are not currently enabled for any end-user applications at this
time.
Q: Is the iCVR camera IR-light sensitive?
A:
Yes, the iCVR has a built-in IR cut filter. The image sensor is sensitive to near-
IR illumination when the filter is enabled.
Q: How big is the camera? Will it fit in my enclosure?
A:
The iCVR Camera and lens combo is typically 9-11 inches long. Most standard
camera housings have sufficient internal length to house the camera and lens
comfortably. VideoIQ also sells a housing optimized to work well with the iCVR
camera.
Q: What PTZ cameras will work with the iCVR encoder?
A:
Any analog PTZ that can respond to Pelco P or D protocol should work well
with the iCVR encoder.
Q: What other IP cameras can be monitored by the VideoIQ View
application?
A:
At this time View does not support monitoring any 3rd party IP cameras.
Q: How much video does the hard drive hold?
A:
This varies somewhat with the amount of alarm activity, as alarm events are
recorded at a higher quality than non-alarm "idle" video.
An 80GB hard drive will typically hold 4-8 weeks of video in the encoder or
camera.
Q: How fast or slow can objects move and still be detected?
A:
The actual speed will depend upon the distance to the object, and the focal
length of the lens.
Here are some general rules:
If the object is clearly visible for two seconds, it should be detected. If it moves
across the whole scene in less than two seconds, it might be missed. With a 10
mm lens at 240’ away, an object would have to move faster than 50 MPH to cross
the whole horizontal FOV of a camera in less than two seconds. However, using
the same lens, a vehicle at half the distance (120’ away) would take only 25 MPH
to cross the whole scene in two
seconds. VideoIQ’s technology can detect objects in as little as 1/3rd of a second
under ideal conditions, but using two seconds is a better rule of thumb.
