Cisco Firewall :: ASA 5510 Q.264 Video From Axis Outdoor Camera Denied

I have a customer with a Cisco ASA 5510 firewall, an inside network containing a Genetec video recording server, and cameras installed on broadband modems throughout the area (each with a public IP). They've recently purchased Axis Q6034-E cameras that use H.264 to stream back to the video recording server. The camera has a view mode where you can watch it through H.264 or Motion JPEG. The view with M-JPEG works, but when I switch to H.264 the video stream is denied. We have allowed RTSP, RTP, and HTTP (it's setup with only http, not 443)traffic from the camera address on the cable company public network but are still being denied the video stream. The recording software requires that the feed come from the H.264 feed, so the motion jpeg does not fix the underlying issue of being able to record.
 
We know it's the firewall because if we install the camera on the inside network, the video feed in H.264 works to the recorder.
 
How to enable something special on the firewall to allow traffic through from the device?
