H.264 Platform Support: H.264, also known as MPEG-4 Part 10, is the latest MPEG standard for video encoding. H.264 is expected to become the video standard of choice in the coming years, because an H.264 encoder can reduce the size of a digital video file by more than 80% compared with the Motion JPEG format and as much as 50% more than with the MPEG-4 standard without compromising image quality. This means that much less network bandwidth and storage space are required for a video file. Or seen another way, much higher video quality can be achieved for a given bit rate.

eSATA Bus Interface: External Serial Advanced Technology Attachment or eSATA is an external interface for SATA technologies. It competes with FireWire and USB 2.0 to provide fast data transfer speeds for external storage devices so that you can record and archive the video from security cameras on hard disks. eSATA supports a data transfer speed of up to 300 MB/s.

Multiple Displays: This NVR supports live-view and playback of the video footage from video security cameras on up to 2 displays simultaneously.

HDMI Port: HDMI stands for High-Definition Multimedia Interface and supports transmission of Full-HD 1080p video. HDMI is an all-digital connector that can carry High-Definition video and several digital audio channels all on a single cable.

Hot-Swap Hard Disks: You don’t need to shut down the entire NVR for replacing a hard disk or adding a new one to the existing configuration.

Powerful CPU: This NVR has a powerful built-in Intel Dual core Central Processing Unit for a seamless processing power as well as true multi-tasking and high performance High Definition video processing.

USB 2.0 Port: Universal Serial Bus is the mostly used interface for external disks and was designed to standardize the connection of computer peripherals. With this feature you can easily save the video footage of the video security cameras on a portable hard disk or flash drive. USB 2.0 supports a data transfer speed of up to 35 MB/s.

Redundant Power Supply: This NVR is equipped with two power supply units, each of which is capable of supplying the power for the entire NVR independently. If one of the units fails, the other one will take over to supply the power to ensure continuous operation of the NVR. You can replace the failed power supply unit without turning off the server.


Alder Series: The Alder series includes security solutions for those who want a high performance security product with a medium cost. The products of the Alder series have all the required features for implementing a reliable and sturdy video security project at a reasonable price. The products of the Alder series are well suited to small to medium sized security projects.
