RGB Spectrum Zio R4020 – 1RU 4TB Zio Stream Recorder

Product Overview

The RGB Spectrum Zio R4020 is a 1RU Zio IP stream recorder with 4TB of recording capacity, used to record and replay Zio video streams in control room and command center deployments. It is the entry capacity in the Zio Recording & Media Server line and installs in a standard rack alongside the encode and decode endpoints that feed it. RGB Spectrum states the Zio recording system records and plays back simultaneously up to 30 IP streams and supports 3840x2160, 60Hz input. Operators recall recorded material for incident review, after-action analysis and training without taking the live system out of service.

Product Description

The Zio R4020 records H.264 and H.265 streams delivered over RTSP in unicast or multicast, which means it consumes the same stream pool as the rest of the Zio AV-over-IP system rather than needing a separate capture path. Its 4TB capacity and single (non-redundant) power supply make it the appropriate choice where retention windows are modest and the recorder is not itself treated as critical infrastructure. RGB Spectrum publishes a first-in, first-out architecture for the platform, so the oldest material is overwritten as new recording continues. Playback features published for the series include single and group playback, jump to time, pause, resume and adjustable playback speeds from 0.1x to 10x, which is what an analyst needs when reconstructing a sequence of events. Management uses the Unified Management Protocol API over JSON and WebSockets, so the recorder integrates with the wider Zio control layer rather than sitting outside it. Sources reach the recorder from encoder endpoints such as the Zio S2114 4K encoder endpoint and the Zio S2112 2K encoder endpoint, and recorded streams can be replayed to decode endpoints like the Zio D2114 4K decoder. Where a customer-supplied Dell R7x0 server is preferred over an RGB Spectrum appliance, the matching software is the 750 12414 single-server license for the Zio Recording and Media Server. Larger retention or redundant power moves the specification to the Zio R4440 8TB recorder or the Zio R4660 12TB RAID recorder.

Key Features

• 4TB recording capacity — RGB Spectrum publishes 4TB of recording capacity for this model, sizing it for shorter retention windows.
• 1RU rack-mount chassis — The recorder occupies a single rack unit, so it fits head-end racks already carrying Zio encode and decode hardware.
• Records H.264 and H.265 — It ingests the same compression formats the Zio platform streams, so no separate transcoding stage is required.
• RTSP unicast and multicast — Published protocol support lets the recorder subscribe to existing multicast groups without duplicating streams.
• Analyst-grade playback control — Single and group playback, jump to time, pause, resume and 0.1x to 10x speeds let operators reconstruct an event precisely.
• UMP API integration — The Unified Management Protocol API over JSON and WebSockets allows the recorder to be driven from the wider Zio control layer.
• Gigabit Ethernet I/O — 1000BASE-T network I/O keeps the recorder on standard commercial network infrastructure.
• Red Hat operating system — The published RedHat operating system gives IT teams a known platform for patching and security review.

Typical Applications

• Control room — Operators replay recorded IP streams to review an incident while the live wall keeps running.
• Command center — Recorded feeds support after-action review and reporting on decisions taken during an event.
• Operations center — Process and monitoring feeds are retained for a short window so anomalies can be re-examined.
• Emergency operations center — Activation footage is captured for debriefing and for the formal record of the response.
• Government space — Agency monitoring positions get a rack-mount recorder that stays within the existing IP video system.
• Broadcast studio — IP contribution and monitoring streams are captured for compliance review and re-cutting.
• Training room — Recorded operational sequences are replayed at adjustable speeds as instructional material.

Frequently Asked Questions

Which streams can the Zio R4020 record?
RGB Spectrum publishes H.264 and H.265 video compression with RTSP unicast and multicast protocols, so it records the same streams the Zio platform distributes.

How much rack space and what network connection does it need?
It is a 1RU chassis with 1000BASE-T Gigabit Ethernet network I/O. RGB Spectrum publishes the R4000 series depth as 808.5mm (31.8"), which matters for shallow racks.

Does it have redundant power supplies?
No. RGB Spectrum publishes redundant power supplies as not fitted on the R4020. Specify the Zio R4440 or Zio R4660 where dual redundant supplies are required.

How does playback work for an analyst?
Published playback features are single and group playback, jump to time, pause, resume and adjustable playback speeds from 0.1x to 10x.

How does it integrate with our control system?
The published interface is the UMP Unified Management Protocol API, carried as JSON over WebSockets.

What happens when the 4TB fills up?
RGB Spectrum publishes a first-in, first-out architecture for the platform, so the oldest recordings are overwritten as new material is written. Size retention against your stream count and bit rates during design.

Does the recorder need a separate software license?
Yes for a customer-supplied server build: the 750 12414 single-server license for the Zio Recording and Media Server covers a Dell R7x0 platform. Confirm the licensing model for this appliance part number with Creation Networks before ordering.

What warranty and support apply?
The RGB Spectrum manufacturer warranty applies to this part number, and Creation Networks supports specification and procurement, including written confirmation of the current warranty terms before you place the order.
