- Support DDNS Server and Assistant Connection Server，the device can be accessed accurately and easily over WAN, though the device uses a dynamic IP address.
- Support working throught NAT devices, allowed to be accessed easily by using an assistant connection address without setting up router.
- Support being identified automaticlly by management software in local area network.
- Support different decoded image streams to save the system and network resources.
- Support adaptive rate control function.
- Support being decoded over WAN by using an EK500 Series Decoder, the decoded image will be output to a TV set or monitor in turn. Dwell time of an image can be adjusted.
- Support web server function, allowed to be accessed expediently via Internet Explorer.
- Built-in embedded Linux operation system, support downloading the software, upgrading and setting the device.
- Support fault detection, recovery and automatic connection.
- Multi-protocols supported: TCP，UDP，HTTP，PPPoE，DHCP，DNS，AGMP，TFTP.
- Variety of power options: DC 12 V, or PoE (Power over Ethernet).
- Choice of compression formats: advanced MPEG4-ASP. MPEG4-SP
- Limits data bit rate while maintaining high-quality images, Ideal when network bandwidth is limited, Useful for calculating the required bandwidth during installation
- Alarm function – with activity detection and pre-/post-alarm recording modes.
- Bi-directional audio function.
