You are submitting the job as userid 48, gid 48 -
does the command normally work OK as a non root userid ?
(The device read by the "capture" command must have appropriate
privileges if you're not running it as root -
which device / what privileges?)
Does the at-job work if submitted as root ?
Do you have SELinux in Enforcing mode ?
If so, does the at job work after doing 'setenforce 0' ?
Try changing the command to:
/home/netwiz/bin/capture '7 HD Digital' 30 || echo "FAILED: $?"
that should generate some mail with the exit status if it fails.
