H.264 transmission | On Off | Set whether to transmit H.264 images. On H.264 images are transmitted. Off H.264 images are not transmitted. When [On] has been selected as the [H.264 transmission] setting, both H.264 images and JPEG images can be displayed on the [Live] screen. When [On] has been selected as the [H.264 transmission] setting, the frame rate for JPEG images may become slower.
Internet mode (over HTTP) | On Off | Set whether to transmit the H.264 images via the Internet. H.264 images can be transmitted using the same broadband router settings as when transmitting JPEG images. On The H.264 images are transmitted using the HTTP port. For details on setting the HTTP port number, see the following page. “HTTP port” Off The H.264 images are transmitted using the UDP port. When [On] is set, only [Unicast port (AUTO)] can be selected as the [Transmission type] setting. When [On] is set, it takes a few seconds before the H.264 images are displayed. When this is set to [On], H.264 images may not appear depending on the number of users accessing the unit at the same time and whether audio data exists.
Image capture size | H264(1) 1920 x 1080 1280 x 720 H264(2) 1920 x 1080 1280 x 720 640 x 360 320 x 180 160 x 90 H264(3) 1280 x 720 640 x 360 320 x 180 160 x 90 H264(4) 1280 x 720 640 x 360 320 x 180 160 x 90 | Select the resolution for H.264 images. Selectable options will vary depending on the selected resolution setting.
Transmission priority | Constant bit rate Frame rate Best effort Advanced VBR | Set the transmission mode for H.264 images. Constant bit rate Transmits H.264 images at the bit rate specified in [Max bit rate (per client)]. Frame rate Transmit H.264 images at the frame rate specified in [Frame rate]. 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. Advanced VBR Transmit H.264 images at the frame rate specified in [Frame rate]. Images will be transmitted so that the average transmission volume during the duration specified in [Control time period] will be the bit rate specified in [Max bit rate (per client)]. When [Transmission priority] is set to [Frame rate] or [Advanced VBR], the number of users that can connect may decrease.
Burst tolerance level | High Middle Low | Select how much more than the [Max bit rate (per client)] value to allow for the H.264 bit rate. This setting is only enabled when [Transmission priority] is set to [Advanced VBR].
Control time period | 1h 6h 24h 1week | Select the duration for which the H.264 bit rate will be controlled. Images will be transmitted so that the average transmission volume during the duration specified will be the bit rate specified in [Max bit rate (per client)]. 1h 1 hour 6h 6 hour 24h 1 day (24 hours) 1week 1 week This setting is only enabled when [Transmission priority] is set to [Advanced VBR].
Frame rate | 59.94 Hz 5fps 15fps 30fps 60fps 50 Hz 5fps 12.5fps 25fps 50fps | Set the frame rate for H.264 images. The [Frame rate] is limited by the [Max bit rate (per client)] setting. The actual frame rate may be lower than the specified value. This setting is only enabled when [Transmission priority] is set to [Frame rate] or [Advanced VBR]. [H.264(1)] is fixed at 60 fps (for 59.94 Hz) and 50 fps (for 50 Hz). 60 fps (for 59.94 Hz) and 50 fps (for 50 Hz) cannot be selected for [H.264(2)] to [H.264(4)].
Max bit rate (per client) | 64kbps 128kbps 256kbps 384kbps 512kbps 768kbps 1024kbps 1536kbps 2048kbps 3072kbps 4096kbps 6144kbps 8192kbps 10240kbps 12288kbps 14336kbps 16384kbps 20480kbps 24576kbps | Specify the H.264 bit rate per client. When [Transmission priority] is set to [Best effort], specify the maximum and minimum bit rate. The H.264 bit rate is limited by [Bandwidth control (bitrate)] under the [Network] tab of the [Network] screen. With a bit rate other than [64kbps], the actual bit rate may be lower than the specified value. “Bandwidth control(bitrate)” The range of H.264 bit rates that can be specified varies depending on the resolution. 160×90: 64kbps to 2048kbps 320×180, 640×360: 64kbps to 4096kbps 1280×720: 256kbps to 8192kbps 1920×1080: 512kbps to 14336kbps 1920×1080 (60fps), 1280×720 (60fps): 1024kbps to 24576kbps Factory settings H.264(1): 4096kbps H.264(2): 1536kbps H.264(3): 1024kbps H.264(4): 512kbps
Image quality | Low (Motion priority) Normal Fine (Image quality priority) | Select the image quality for H.264 images. This setting is only enabled when [Transmission priority] is set to [Constant bit rate] or [Best effort].
Refresh interval | 59.94 Hz 0.2s 0.25s 0.33s 0.5s 1s 2s 3s 4s 5s 50 Hz 0.2s 0.5s 1s 2s 3s 4s 5s | Set the refresh interval for H.264 images (I-frame interval: 0.2 to 5 seconds). 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"). “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 H.264 (4) : 32034 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.
