Q: What lenses will work with the iCVR Camera?
A: The iCVR accepts any C or CS (with included adapter) mount lens. Lenses
with edge distortion should be avoided as this can reduce the accuracy of the
analytics algorithms.
Q: How many iCVR camera/encoder devices can I manage from the View
application?
A: View can effectively manage an unlimited number of cameras, provided the
PC meets the basic recommended specs.
Additionally, every camera can be monitored by up to 3 View stations at a time.
Q: What ports do I need to open on my firewall for remote camera access?
A: If you only have one camera, the easiest method is to make the camera the
"DMZ" host. This will send all incoming connections to the camera.
If you are using multiple cameras, or other publicly accessible devices, behind a
single firewall, you will need the following ports open:
443 - https control access
554 - rtsp video stream
5401 - VideoIQ control port
22022 - Audio talk-down port (note, if you are not using the audio function, you do
not need to configure/open this port).
Port-forwarding rules differ by manufacturer and router model, so consult your
routers manual for exact setup instructions.
Q: How much bandwidth do I need for my camera?
A: The amount of bandwidth used at any given time will fall into 1 of 3 general
categories:
1) View live-video in a small window.
This uses 100Kbps per camera, per viewer. ie: 1 person viewing 1 camera will
use 100Kbps. 1 person viewing 2 cameras uses 200Kbps. 2 people viewing
the same camera uses 200Kbps
2) View live-video in a large window.
This uses 500-750Kbps per camera, per viewer. The high-res stream details
can be customized in the Storage and Compression tab of the Camera
Settings.
3) Transferring an alarm clip video.
This happens as a file transfer, not a video stream. The alarm clips are
~100KB, and are sent to every PC logged into the camera. Alarm clip
transfers work much like email attachments, they will use whatever bandwidth
is available and are small enough to not interfere with other traffic. Faster
connections mean the clips get to the PC faster.
