The Synology DVA1622 is a Network Video Recorder (NVR) for surveillance with up to 16 IP cameras. The device is designed as a 2-bay system, meaning it supports two internal SATA-formatted hard drives for storing video recordings. It is based on an Intel Celeron J4125 processor with four cores and a clock speed of 2.0 GHz, which handles the processing of video and audio streams. The integrated memory size is 6 GB DDR4, sufficient to ensure simultaneous processing of multiple video and audio streams. The device is designed for use in surveillance systems based on IP camera networks and supports various compression formats such as MJPEG, MPEG-4, H.264, H.265, G.711, G.726, AAC, PCM, and AMR. These formats enable efficient storage and transmission of video and audio data, with H.265 and H.264 providing particularly high compression efficiency to save storage space.

Applications

The DVA1622 is designed for use in security systems requiring central video recording and management. It is particularly suitable for small to medium-sized businesses, retail stores, warehouses, or residential complexes where structured surveillance with multiple cameras is required. The support for up to 16 IP cameras enables comprehensive coverage of the surveillance area. The integrated Deep-Learning functionality supports intelligent video content analysis, for example, detecting motion, people, or specific events, thereby making surveillance more efficient.

Functions and Equipment in Detail

The device features two SATA ports intended for installing two 3.5-inch hard drives. Video and audio data processing is handled by the Intel Celeron J4125 processor, designed for stable performance when processing multiple streams simultaneously. The 6 GB DDR4 RAM ensures sufficient memory to meet the requirements of video processing and operating system functions. Supported operating systems include Windows 7, Windows 10, and macOS 10.11, facilitating integration into existing IT infrastructures. The integrated Deep-Learning technology enables intelligent video analysis, which can be used, for example, to detect motion, people, or specific events.

Technology Explained Simply

The DVA1622 functions as a central control unit for IP surveillance cameras. The cameras transmit their video and audio data over a network to the NVR, which records and stores the data. Data compression occurs in various formats, with H.265 and H.264 being particularly efficient as they enable high image quality with small file sizes. The Deep-Learning function analyzes video content in real time and can recognize specific patterns, such as the appearance of a person or unusual movement. This reduces the need to manually review the entire recording. Processing is handled by the Intel Celeron J4125 processor, designed for balanced performance with moderate power consumption.

Compatibility and Accessories

The NVR is designed for use with IP cameras connected via network cables (Ethernet). The maximum number of supported cameras is 16. Compatibility with various video and audio formats such as MJPEG, MPEG-4, H.264, H.265, G.711, G.726, AAC, PCM, and AMR enables integration with different camera systems.

Installation and Mounting

The DVA1622 is designed as a desktop device and can be placed on a table or in an enclosure. Installation involves connecting the IP cameras via Ethernet cables to the network, with video and audio data sent to the NVR. The hard drives are inserted into the two SATA bays. Configuration is performed via a user interface accessible over the network. Supported operating systems (Windows 7, Windows 10, macOS 10.11) allow control and monitoring from a computer.

Operational Advantages

Using the DVA1622 provides central, structured video recording with high scalability up to 16 cameras. The Deep-Learning function enables intelligent video analysis, reducing the need for manual review of recordings. Support for various compression formats ensures efficient storage, with H.265 and H.264 saving significant space. Processing by the Intel Celeron J4125 processor ensures stable performance, and the 6 GB RAM provides sufficient memory. Compatibility with common operating systems facilitates integration into existing IT systems.
