Mechanical Characteristics:
The Connection Rack models are constructed with aluminum housing, weighing approximately 6 kg for the Q model and 8 kg for the Q2 model. Both models share dimensions of 482.6 x 177.8 x 405 mm (WxHxD), fitting into a 4U rack space.

Power Supply:
Both models operate on a power supply of 100-240 VAC with a frequency range of 47-63 Hz. The input current is less than 1 A at 230 VAC, and they include a 2A external fuse. They comply with VDE 0160 / W2 standards for transient loads.

Field and Control Power:
The field and control voltage ranges from 12VDC to 30VDC, with a 2000mA mT fuse for the field circuit, depending on the camera type.

Interfaces:
The power supply is connected via internal terminal blocks, with camera connectors available for one to four cameras. Optional binary inputs and outputs are available as dry contacts. Ethernet connectivity includes RJ45, fiber connectors, or wireless access points, depending on the model.

Functionality:
The Connection Rack series converts video, audio, and optional binary signals into Ethernet network streams, serving as a power supply, digitizer, and control interface for connected cameras. It supports various PTZ cameras from different manufacturers and requires minimal installation time due to channel-specific terminal blocks.

Video Encoder:
The Q model supports 4 x H.264 and Motion JPEG streams, while the Q2 model supports 8 x H.264 and Motion JPEG streams. Both models offer resolutions from 720x480 to 176x120 (NTSC) and 720x576 to 176x144 (PAL), with a frame rate of 30/25 fps. Video streaming allows for multiple configurable streams per channel.

Image Settings:
Features include compression, color, brightness, contrast adjustments, rotation, aspect ratio correction, mirroring, text and image overlay, privacy mask, and an enhanced deinterlace filter.

PTZ Interface & Drivers:
The Q model supports 4 x RS422 or RS485 interfaces, while the Q2 model supports 8 x RS422 or RS485 interfaces, with RS232 as an option.

Audio:
Audio streaming is two-way, full duplex for the Q model, and two-way, half-duplex for the Q2 model on specific channels. Audio compression formats include AAC-LC, G.711 PCM, and G.726 ADPCM.

Network:
Ethernet connectors vary by model, supporting Cat6 copper cables, fiber optic cables, and integrated wireless access points. The Q model requires 4 TCP/IP addresses, while the Q2 model requires 8. Security features include password protection, IP address filtering, HTTPS encryption, and IEEE 802.1X network access control.

Supported Protocols:
The models support a wide range of protocols, including IPv4/v6, HTTP, HTTPS, IEEE 802.1X, QoS, FTP, SMTP, Bonjour, UPnP, SNMP, DNS, DynDNS, NTP, RTSP, RTP, TCP, UDP, IGMP, RTCP, ICMP, DHCP, ARP, and SOCKS.

Model Variants:
The Connection Rack models are identified by specific codes indicating Ethernet connection types and audio capabilities, with options for integrated DECT base stations and amplifiers for speaker connections.
