CCTV Camera Pros' JPEG2000 dual codec surveillance DVR includes a DVR remote viewer software package called the IRS (integrated remote station). The manufacturer that makes this DVR for us has recommended the below best practices when a customer is having connection trouble when using the "transmitter" remote Internet viewing function of the JPEG2000 dual codec DVR.
Here are a few tips to follow when using the remote viewer & transmitter functions on the DVR. Installers please use this as a troubleshooting guide for connectivity issues. Please make sure to take time to explain to your customers also that many times, Internet connectivity causes connection drops and not the actual surveillance hardware.
- Be sure that the customers clicks "Disconnect" before closing any instances of the client software.
- Ask your customer if they are doing the remote connection from a
wired line or wireless connection, wireless connections can drop or
timeout before you have the chance to properly disconnect and end the
- When using Transmitter, make sure that the bitrate set in the
"SETUP" part of the Transmitter is less than or equal to the actual
connection bitrate, usually the default bitrate is 500Kbps and most
bitrate connections are around 200Kbps from a remote location. Having
the SETUP bitrate higher than the real bitrate connection speed can
lead to network bottlenecks and timeouts. Our office machine has these
Also, have your customer do a speed test at the DVR location (http://www.speedtest.net)
and check the upload speed, you customer should have at least a
consistent 384Kbps upload at the DVR location for the remote connection
to be practical.
Finally, check the firmware for the DVRs that are giving you
problems, if the Dual Codec DVR has a firmware older than 1.34 then
update to the version 1.34.
Please remember that we also need to isolate all other factors by
connecting the DVR directly to a PC with a crossover cable and connect
for an extended periods of time to see if we can duplicate the network
problems. Our office dual codec has firmware 1.34 and network wise is
rock solid (never disconnects).
