The Network Camera offers the highly efficient H.264 video compression, which drastically reduces bandwidth and storage requirements without compromising image quality. Motion JPEG is also supported for increased flexibility.

• Dual streams

The Network Camera can deliver dual video streams simultaneously at full frame rate in all resolutions up to Full-HD(1920 x 1080p) using Motion JPEG and H.264 (or MPEG-4). This means that several video streams can be configured with different compression formats, resolutions and frame rates for different needs.

• Image setting adjustment

The Network Camera also enables users to adjust image settings such as contrast, brightness and saturation to improve images before encoding takes place.

• Intelligent video capabilities

The Network Camera includes intelligent capabilities such as enhanced video motion detection.

The encoder’s external inputs and outputs can be connected to devices such as sensors and

relays, enabling the system to react to alarms and activate lights or open/close doors.

• Resolution

The Network Camera supports two kinds of resolutions according to the model name.

HDG-T302, HDB-T3x2 Series, 1 Megapixel, 30fps@1280x720 HDG-T322, HDB-T3x2 Series, 2 Megapixel, 30fps@1920x1080

• Micro-SD Recording support The Network Camera also supports a micro-SD memory slot for local recording with removable storage.

• Improved Security

The Network Camera logs all user access, and lists currently connected users. Also, its full frame rate video can be provided over HTTPS.

• Power over Ethernet

Support for Power over Ethernet (IEEE802.3af) enables the unit, as well as the camera module that is connected to it, to receive power through the same cable as for data transmission. This makes for easy installation since no power outlet is needed.

• ONVIF

 Enable anonymous viewer login: Check the box to use the webcasting features. Refer to

“3.5.2 Video & Image” for more details.

2) Network

The network camera support both IP version 4 and IP version 6. Both versions may be enabled simultaneously, and at least one version must always be enabled. When using IPv4, the IP address for the video encoder can be set automatically via DHCP, or a static IP address can be set manually. If IPv6 is enabled, the video encoders receive an IP address according to the configuration in the network router. There is also the option of using the Internet Dynamic DNS Service. For more information on setting the Network, please see Setup> System>Security>Network.

• Obtain IP address via DHCP - Dynamic Host Configuration Protocol (DHCP) is a protocol

that lets network administrators centrally manage and automate the assignment of IP addresses on a network. DHCP is enabled by default. Although a DHCP server is mostly used to set an IP address dynamically, it is also possible to use it to set a static, known IP address for a particular MAC address.

• Use the following IP address - To use a static IP address for the Network Camera,

check the radio button and then make the following settings:

- IP address: Specify a unique IP address for your Network Camera.

- Subnet mask: Specify the mask for the subnet the Network Camera is located on.

- Default router: Specify the IP address of the default router (gateway) used for

connecting devices attached to different networks and network segments.

Notes:

1. DHCP should only be enabled if using dynamic IP address notification, or if your DHCP server can update a DNS server, which then allows you to access the Network Camera by name (host name). If DHCP is enabled and you cannot access the unit, you may have to reset it to the factory default settings and then perform the installation again.

2. The ARP/Ping service is automatically disabled two minutes after the unit is started, or

as soon as an IP address is set.

3. Pinging the unit is still possible when this service is disabled.

3) Video & Image

• Video Setting

- Codec:

The codec settings are separated into MPEG4 and H.264.

H.264 is also known as MPEG-4 Part 10. This is the new generation compression standard for digital

video. This function offers higher video resolution than Motion JPEG or MPEG-4 at the same bit rate and bandwidth, or the same quality video at a lower bit rate.

- Profile:

There are 4 pre-programmed stream profiles available for quick set-up. Choose the form of video encoding you wish to use from the drop-down list:

* H.264 MP(Main Profile):

Primarily for low-cost applications that requires additional error robustness, this profile is used rarely in videoconferencing and mobile applications, it does add additional error resilience tools to the Constrained Baseline Profile. The importance of this profile is fading after the Constrained Baseline Profile has been defined.

* H.264 BP(Base Profile):

Originally intended as the mainstream consumer profile for broadcast and storage applications, the importance of this profile faded when the High profile was developed for those applications.

* MPEG4 SP(Simple Profile):

Mostly aimed for use in situations where low bit rate and low resolution are mandated by other conditions of the applications, like network bandwidth, device size etc.

* MPEG4 ASP(Advanced Simple Profile):

Its notable technical features relative to the Simple Profile, which is roughly similar to H.263, including "MPEG"-style quantization, interlaced video, B pictures (also known as B Frames), Quarter Pixel motion compensation (Qpel), Global motion compensation (GMC).

- Resolution:

It enables users to determine a basic screen size when having an access through the Web Browser or PC program. The screen size control comes in seven modes like 1920x1080, 1280x1024, 1280x720, 704x480(576), 640x480, 352x240(288), and 320x240. Users can reset the selected screen size anytime while monitoring the screen on a real-time basis.

- Bitrate control:

Limiting the maximum bit rate helps control the bandwidth used by the H.264 or MPEG-4 video stream. Leaving the Maximum bit rate as unlimited maintains consistently good image quality but increases bandwidth usage when there is more activity in the image. Limiting the bit rate to a defined value prevents excessive bandwidth usage, but images are lost when the limit is exceeded.

Note that the maximum bit rate can be used for both variable and constant bit rates.

The bit rate can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image complexity, using up bandwidth for increased activity in the image, and less for lower activity in the monitored area.

CBR allows you to set a fixed target bitrate that consumes a predictable amount of bandwidth. As the bit rate would usually need to increase for increased image activity, but in this case cannot, the frame rate and image quality are affected negatively. To partly compensate for this, it is possible to prioritize either the frame rate or the image quality whenever the bit rate needs to be increased. Not setting a priority means the frame rate and image quality are equally affected.

- Compression:

When it is necessary to adjust a smooth transmission status according to network situations, users can increase the compressibility to carry out the network transmission stably. On the other hand, when it is necessary to maintain a detailed monitoring screen by enhancing the image quality, users can do so by decreasing the compressibility. In ease case, please adjust this function according to the network status and monitoring purposes. The default is 2000(Kbps).

- Frame rate:

Upon the real-time play, users should select a frame refresh rate per second. If the rate is high, the image will become smooth. On the other hand, if the rate is low, the image will not be natural but it can reduce a network load.

- GOP size:

Select the GOP(Group of Picture) size. If users want to have a high quality of fast image one by one, please decrease the value. For the purpose of general monitoring, please do not change a basic value. Such act may cause a problem to the system performance. For the details of GOP setting, please contact the service center.

• Image Setting

Sometimes the image size is large due to low light or complex scenery. Adjusting the frame rate and quality helps to control the bandwidth and storage used by the Motion JPEG video stream in these situations. Limiting the frame rate and quality optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage, the Resolution, Frame rate, and Frame Quality should be set to an optimal value.

- JPEG resolution:

Same as the video settings.

- JPEG frame rate:

Same as the video settings.

- JPEG quality:

Select the picture quality. If users want to have a high quality of fast image one by one, please decrease the value. For the purpose of general monitoring, please do not change a basic value. Such act may cause a problem to the system performance.

When satisfied with the settings, click Save, or click Reset to revert to previously saved settings.

4) Audio

The Network Camera can transmit audio to other clients using an external microphone and can play audio received from other clients by attaching a speaker. The Setup page has an additional menu item called Audio, which allows different audio configurations, such as, full duplex, and simplex.

• Audio Setting

- Enable audio:

Check the box to enable audio in the video stream.

- Compression type:

Select the desired audio Compression format, G711.

- Sample rate:

Select the required Sample rate (number of times per second the sound is sampled). The higher the sample rate, the better the audio quality and the greater the bandwidth required.

- Sound bitrate:

Depending on the selected encoding, set the desired audio quality (bitrate). The settings affect the available bandwidth and the required audio quality.

• Audio Input

Audio from an external line source can be connected to the terminal I/O of the network camera.

- Input volume:

If there are problems with the sound input being too low or high, it is possible to adjust the input gain for the microphone attached to the network camera.

• Audio Output

- Enable full duplex:

Check the box to enable Full Duplex mode. It means that you can transmit and receive audio (talk and listen) at the same time, without having to use any of the controls. This is just like having a telephone conversation.

This mode requires that the client PC has a sound card with support for full-duplex audio.

Uncheck the box enable Simplex mode. The simplex mode only transmits audio from the network camera to any web client. It does not receive audio from other web clients.

- Output volume:

If the sound from the speaker is too low or high it is possible to adjust the output gain for the active speaker attached to the network camera.

When satisfied with the settings, click Save, or click Reset to revert to previously saved settings
