  • If images are not transmitted at the specified frame rate, lowering the resolution or image quality may result in transmissions closer to the specified value.

When [H.264 transmission] is set to [On], the frame rate may be slower than the specified value in some cases.

Best effort

Transmit H.264 images at a variable bit rate between the maximum and minimum specified in [Max bit rate (per client)], according to the network bandwidth.

  • If errors occur frequently in the network environment, decreasing the refresh interval will reduce image distortions. However, the frame rate may decrease.

Transmission type

Unicast port (AUTO)

Unicast port (MANUAL)

Multicast port

Set the transmission format for H.264 images.

Unicast port (AUTO)

Up to 14 users can access a single camera at the same time.

[Unicast port] will be configured automatically when images are sent from the camera.

We recommend selecting the [Unicast port (AUTO)] setting when the port number transmitting the H.264 images does not need to be fixed (e.g., during use within a network).

Unicast port (MANUAL)

Up to 14 users can access a single camera at the same time.

[Unicast port] must be configured manually when images are sent from the camera.

When transmitting H.264 images via the Internet, configure a fixed transmission port number for the broadband router (hereafter referred to as "router").

100414.png“HTTP port”

For details, refer to the operating instructions for the router.

Multicast port

An unlimited number of users can access a single camera at the same time.

When transmitting H.264 images via multicast, enter the [Multicast address], [Multicast port], and [Multicast TTL/HOPLimit].

When transmitting H.264 images via multicast, use a multicast-compatible router, and specify the transmission destination. In such cases, configure settings so that H.264 images are not transmitted to other connected devices (e.g., AK-HRP1000). IP communication with the camera may be disabled if you transmit H.264 images to the AK-HRP1000.

Maximum number of simultaneous accesses

Up to 14 users (consisting of users receiving H.264 images and users receiving JPEG images) can access the unit at the same time. However, depending on the settings for the [Bandwidth control(bit rate)] and [Max bit rate (per client)], the number of users who can access the unit may be limited to less than 14. A message indicating the access limit will appear if the number of users exceeds 14. When [Transmission type] is set to [Multicast port] for [H.264], the second and subsequent users receiving H.264 images will not be counted toward the total access count.

Unicast port

1024 to 50000

Set the unicast port number (used when sending images from the unit).

This needs to be set when [Transmission type] is set to [Unicast port(MANUAL)].

  • Factory settings

H.264 (1) : 32004

H.264 (2) : 32014

H.264 (3) : 32024

  • Only even numbers can be specified.
  • The port number cannot be set to 10670.

Multicast address

224.0.0.0 to 239.255.255.255

Set the multicast IP address.

Images will be sent to the specified IP address.

This needs to be set when [Transmission type] is set to [Multicast port].

  • Factory settings

H.264 (1) : 239.192.0.20

H.264 (2) : 239.192.0.21

H.264 (3) : 239.192.0.22

H.264 (4) : 239.192.0.23

  • Verify the usable multicast IP addresses before setting this.

Multicast port

1024 to 37004 to 50000

Enter the multicast port number (used when sending images from the unit).

This needs to be set when [Transmission type] is set to [Multicast port].

  • Only even numbers can be specified.
  • The port number cannot be set to 10670.

Multicast TTL/HOP Limit

1 to 16 to 254

Enter the TTL/HOP Limit value for multicast.

This needs to be set when [Transmission type] is set to [Multicast port].

  • When transmitting H.264 images via the Internet, transmitted images may not appear depending on proxy server settings, firewall settings, etc. In such cases, consult your network administrator.
  • When displaying multicast images on a personal computer with multiple LAN cards installed, disable the LAN cards that are not used for reception.
