Hanwha SKY-SU305-0 Wisenet SKY Bridge 305 Cloud Video Gateway
Overview
The Hanwha SKY-SU305-0 is the Bridge 305 — a compact, ruggedized edge appliance for the Wisenet SKY cloud-managed video platform. It handles up to 15 channels at 1MP or 12 channels at 4MP, runs analytics on up to 5 simultaneous channels, and stores up to two days of local video to its built-in 1TB HDD before syncing upstream. For integrators deploying cloud-managed surveillance at distributed sites — retail branches, warehouses, small commercial facilities — the SKY-SU305-0 eliminates the need for a full on-site NVR while keeping local buffering intact if the WAN link drops.
This device requires a Wisenet SKY subscription agreement. It is not a standalone NVR and does not operate independently of the Wisenet SKY cloud platform. Factor that licensing cost into your total project budget before specifying.
Key Features
- 4x PoE Ports (802.3af): Power and connect up to four cameras directly from the Bridge 305 without a separate PoE switch or injectors — useful for small satellite sites where minimizing rack or closet hardware matters.
- 15-Channel / 12-Channel Capacity: Handles up to 15 camera channels at 1MP or 12 channels at 4MP. A mixed 4MP/1MP deployment will land somewhere in between — size your camera count accordingly. For sites needing more than 12 channels of 4MP coverage, step up to the Bridge 401 or 406+ in the same family.
- Analytics on 5 Simultaneous Channels: Five concurrent analytics channels is meaningful for a compact appliance in this class — enough to cover entry points, a loading dock, and a parking lot entrance at a mid-size branch without cloud processing overhead on every stream.
- 1TB Built-In HDD with Up to 2 Days Local Buffering: When a WAN outage hits, the Bridge 305 (SKY-SU305-0) keeps recording locally for up to 48 hours and resumes cloud sync when connectivity restores. That resilience matters for retail or logistics sites where network reliability isn't guaranteed.
- HDMI and DisplayPort Video Outputs: Both HDMI and DisplayPort outputs let you connect a local monitor for on-site live view or review without pulling footage through the cloud — useful during commissioning, security desk setups, or when a fast local playback check is needed.
- Compact and Ruggedized Form Factor: The Bridge 305 is built for deployment outside the controlled data center — think back-of-house server rooms, utility closets, or light-industrial environments where a standard rack appliance would be overkill or impractical.
Integration & Compatibility
The SKY-SU305-0 operates exclusively within the Hanwha Vision Wisenet SKY cloud-managed surveillance platform. It is not a general-purpose NVR and does not support third-party VMS platforms such as Milestone or Genetec in a standalone configuration. If your project requires an open-protocol NVR or on-premise VMS, evaluate Hanwha's Wisenet WAVE NVR line instead.
Camera compatibility is scoped to Wisenet SKY-supported camera models. Before specifying cameras alongside this bridge, verify each model appears on the current Wisenet SKY IP camera compatibility list — not all Hanwha cameras are SKY-enrolled. The four integrated PoE ports (802.3af) cover standard PoE cameras; cameras requiring PoE+ (802.3at) will need a separate PoE switch upstream.
For larger sites requiring more channels or higher analytics capacity, the Bridge 405 (SKY-SU406p-0) scales to 35 channels at 4MP with 15 analytics channels and adds LPR support, while the Bridge 501 (SKY-SU501-0) extends to 50 channels at 4MP in a rack form factor. Both are available in the same Wisenet SKY video management appliance family.
Frequently Asked Questions
Q: Does the SKY-SU305-0 require an ongoing subscription to operate?
A: Yes. The Bridge 305 is part of the Wisenet SKY cloud-managed video platform and requires an active Wisenet SKY agreement. It does not function as a standalone NVR without that subscription.
Q: How many cameras can the SKY-SU305-0 support?
A: Up to 15 channels at 1MP, or up to 12 channels at 4MP. Analytics processing is available on up to 5 simultaneous channels. Mixed-resolution deployments will fall between these limits.
Q: What happens to recorded video if the internet connection goes down?
A: The Bridge 305 stores up to 2 days of local video on its built-in 1TB HDD during a WAN outage. Recording resumes cloud sync automatically once connectivity is restored.
Q: Can I connect cameras directly to the SKY-SU305-0?
A: Yes. The unit includes 4 PoE ports (802.3af) for powering and connecting cameras directly without a separate PoE switch. Cameras requiring PoE+ (802.3at) will need an external PoE switch.
Q: Does the SKY-SU305-0 work with third-party VMS platforms like Milestone or Genetec?
A: The Bridge 305 is designed for the Wisenet SKY platform specifically and is not documented to operate with third-party VMS software. For open-protocol NVR compatibility, consider Hanwha's Wisenet WAVE NVR line.
Q: What local display outputs does the SKY-SU305-0 provide?
A: The unit includes both HDMI and DisplayPort outputs, allowing connection of a local monitor for on-site live viewing or playback without routing through the cloud.
The SKY-SU305-0 is the entry point in the Wisenet SKY Bridge line, and the spec that matters most in the field is the 2-day local buffer backed by a 1TB HDD. When I'm scoping cloud-managed deployments for multi-site clients, WAN reliability at the branch level is always the conversation — the Bridge 305 answers that with enough local headroom to ride out most outages without gap in evidence.
Technical Highlights:
- 12-Channel 4MP Capacity: Twelve 4MP streams is a realistic ceiling for a branch site — most small commercial locations top out at 8–10 cameras, so the Bridge 305 has room to grow without forcing an appliance swap mid-contract.
- 5 Analytics Channels: Five concurrent analytics streams on a compact ruggedized appliance keeps edge processing available without cloud dependency — critical when latency on alerts matters (perimeter breach, queue detection).
- 4x Integrated PoE (802.3af) Ports: Four direct-connect PoE ports handle the closest cameras without a downstream switch. For sites with more than four cameras, you'll need a PoE switch feeding into the unit — plan that into your cabling design early.
Deployment Considerations:
- The Bridge 305 is platform-locked to Wisenet SKY — verify the subscription is budgeted and the customer understands the recurring cost model before the equipment ships. A camera count change mid-project can shift the channel tier.
- Standard PoE (802.3af) only on the integrated ports — any camera requiring 802.3at (PoE+) must be on an external switch. Don't assume all Wisenet cameras in the catalog are 802.3af-compatible.
The SKY-SU305-0 fits cleanly into distributed retail or light-commercial deployments of 8–12 cameras per site where cloud management is the architecture decision and local IT presence is minimal — the ruggedized form factor survives back-room environments, and the 2-day buffer covers weekend WAN outages without intervention.
