Product Overview
Managing a large surveillance network across an industrial facility, warehouse, or remote infrastructure site calls for switching infrastructure that can handle high-power PoE, fibre backhaul, and managed network control in a single compact unit. The DS-3T1512HP-SI/8P4F is an 8-port Gigabit smart managed industrial Hi-PoE switch with 4 SFP fibre ports, built for professional CCTV deployments where network reliability and managed control are critical. Ports 1 to 4 support 802.3bt Hi-PoE with up to 90W per port for compatible high-power PTZ cameras and demanding PoE devices, while Ports 5 to 8 provide standard PoE and PoE+ at up to 30W per port. Featuring a 300W total PoE budget, a -40°C to 75°C operating temperature range, 6kV surge protection, dual power input with hot backup, and Hik-Partner Pro remote management, this switch is suited to industrial CCTV networks, outdoor enclosures, and large-scale fibre-connected surveillance systems.
Key Capabilities
802.3bt Hi-PoE on Ports 1 to 4
Ports 1 to 4 support IEEE 802.3bt with up to 90W per port, enabling compatible high-power PTZ cameras and demanding outdoor PoE devices to be powered directly from the switch without separate power supplies at each camera location.
4 Gigabit SFP Fibre Ports
Four Gigabit SFP fibre optical ports support long-distance network backhaul, redundant uplinks, and distributed surveillance layouts where copper cabling cannot reach the core switch, NVR, or control room from remote camera clusters.
300W Total PoE Budget
A 300W total PoE power budget supports mixed deployments combining Hi-PoE PTZ cameras on Ports 1 to 4 and standard PoE cameras on Ports 5 to 8, giving installers flexibility when planning power allocation across multi-camera systems.
Smart Managed Network Control
VLAN, QoS, SNMP, DHCP snooping, ACL, port isolation, PoE watchdog, and STP/RSTP/ERPS loop prevention provide the managed-switch features needed for professional CCTV network segmentation, fault recovery, and traffic prioritisation.
Industrial Build and Surge Protection
A metal IP40 shell, 6kV surge protection, -40°C to 75°C operating temperature range, and dual power input with hot backup make this switch suitable for outdoor enclosures, plant rooms, and industrial sites exposed to harsh environmental and power conditions.
Hik-Partner Pro Remote Management
Hik-Partner Pro integration provides remote access to port rate, bandwidth utilisation, PoE power usage, network topology, alarms, port and device restart, long-range mode, and remote firmware upgrades, reducing site visits for routine monitoring and troubleshooting.
Best For
- High-Power PTZ Camera Networks: Ports 1 to 4 support 802.3bt Hi-PoE at up to 90W per port, making this switch well suited to systems where compatible PTZ cameras require more power than standard PoE or PoE+ can provide.
- Industrial and Manufacturing Facilities: The -40°C to 75°C operating range, metal IP40 shell, 6kV surge protection, and dual power input with hot backup support demanding industrial environments where standard commercial switches are not appropriate.
- Large Sites Requiring Fibre Backhaul: Four Gigabit SFP ports allow fibre uplinks to connect remote camera cabinets, distributed enclosures, or sub-switch clusters back to a central NVR or core network over distances not practical with copper cabling.
- Managed CCTV Networks with VLAN Requirements: IEEE 802.1Q VLAN with up to 4094 VLAN IDs allows surveillance traffic to be segmented from other business systems, improving network organisation and reducing interference between traffic types.
- Remote Installations Needing Managed Oversight: Hik-Partner Pro support allows technicians to monitor port status, PoE power draw, topology, and alarms, and to restart ports or devices remotely, reducing costly call-outs to remote or difficult-to-access sites.
Why Choose the DS-3T1512HP-SI/8P4F
The DS-3T1512HP-SI/8P4F goes well beyond a basic unmanaged PoE switch by combining 802.3bt Hi-PoE, fibre uplink flexibility, industrial construction, and a comprehensive set of managed-switch features in a compact rail-mountable unit. A simpler switch cannot deliver 90W per port on demand for compatible PTZ cameras, provide 4 dedicated SFP fibre ports for long-distance backhaul, or offer PoE watchdog to automatically restart non-responsive cameras without manual intervention. The -40°C to 75°C operating range and 6kV surge protection address installation environments where standard commercial switching hardware would not be appropriate. Long-range transmission support up to 300m, cable detection for fault diagnosis, and Hik-Partner Pro remote management add practical value for multi-site and remote installations. Available through Security Wholesalers, this switch is a considered choice for professional installers who need smart industrial PoE switching with fibre capability built in from the start.
Buyer Decision Tips
PoE Budget and Power Supply Sizing: Before installation, calculate the total PoE draw across all connected devices. Ports 1 to 4 can each deliver up to 90W, but the switch has a 300W total PoE budget shared across all 8 ports. If all 4 Hi-PoE ports are loaded near maximum, the remaining budget for Ports 5 to 8 is reduced accordingly. Size the DC power supply to match your expected load, using the Hikvision-recommended NDR-75-48, NDR-240-48, or NDR-480-48 depending on total draw, and allow headroom above your calculated maximum to avoid thermal throttling or power cutbacks.
SFP Module Compatibility and Fibre Design: The 4 SFP ports accept Gigabit SFP modules, but the switch does not include SFP modules in the box. Confirm which modules are compatible for your fibre type (single-mode or multi-mode), wavelength, and required distance before ordering. Also plan your VLAN structure, loop prevention mode (STP, RSTP, or ERPS), and grounding requirements for the installation enclosure before commissioning, as these settings affect network stability once cameras are live.

Ideal Use Cases
Industrial CCTV Systems
Factories, processing plants, and industrial yards with demanding environmental conditions benefit from the -40°C to 75°C operating range, metal IP40 shell, 6kV surge protection, and dual power input with hot backup, which are not available on standard commercial PoE switches.
High-Power PTZ Camera Deployments
Sites requiring compatible 802.3bt PTZ cameras powered via PoE can use Ports 1 to 4 to deliver up to 90W per port, avoiding separate power injectors or local power supplies at each camera position in car parks, perimeter lines, and large open areas.
Remote Cabinet and Fibre Uplink Networks
Remote camera enclosures on large campuses, transport infrastructure, or distributed outdoor sites can connect back to a core network via the 4 SFP fibre ports, providing a Gigabit backhaul path without relying on copper cabling over long distances.
Managed Surveillance Networks Requiring VLAN Segmentation
Professional CCTV installations on shared business networks can use 802.1Q VLAN with up to 4094 VLANs to separate surveillance traffic from corporate or guest data, with DHCP snooping, ACL, and port isolation providing additional access control at the switch level.
Warehouses and Logistics Facilities
Large warehouse environments covering loading docks, internal bays, and yard areas can use the 300W PoE budget across 8 ports for camera coverage clusters, with PoE watchdog automatically restarting non-responsive cameras to reduce downtime without requiring a site visit.
Choosing the Right Model
- Choose this model if: Your installation requires 802.3bt Hi-PoE for compatible high-power PTZ cameras, fibre uplinks via SFP for long-distance backhaul, smart managed functions such as VLAN, QoS, and PoE watchdog, and an industrial-rated switch that can operate reliably in wide-temperature or surge-prone environments.
- Choose a different model if: Your site uses only standard 802.3af/at cameras with no Hi-PoE devices and no fibre uplink requirement, in which case a smaller unmanaged or basic managed PoE switch may provide the port count you need at lower cost and with simpler configuration.
- Choose a different model if: You need more than 8 PoE camera connections from a single switch, as this model provides 8 PoE RJ45 ports and a 300W budget that may not accommodate very large camera clusters without supplementary switches added to the network design.
FAQs
- What does the DS-3T1512HP-SI/8P4F do, and who is it designed for?
The DS-3T1512HP-SI/8P4F is an 8-port Gigabit smart managed industrial Hi-PoE switch with 4 SFP fibre ports. It is designed for professional CCTV installers who need to power and manage IP cameras, support high-power PTZ cameras via 802.3bt Hi-PoE, connect remote camera clusters via fibre, and control network behaviour through VLAN, QoS, and PoE watchdog functions.
- Which ports on the DS-3T1512HP-SI/8P4F support 802.3bt Hi-PoE, and how much power can they deliver?
Ports 1 to 4 support IEEE 802.3bt Hi-PoE with a maximum of 90W per port. Ports 5 to 8 support IEEE 802.3af and 802.3at with a maximum of 30W per port. The total PoE power budget shared across all 8 ports is 300W, so the combined draw of all connected devices must remain within this limit.
- What is the total PoE power budget, and how should it be calculated for a multi-camera system?
The total PoE budget is 300W. To calculate your load, add up the PoE draw of every connected device. If you connect 4 cameras drawing 60W each on Ports 1 to 4, that uses 240W, leaving 60W for Ports 5 to 8. Exceeding the total budget will cause the switch to reduce power to lower-priority ports, so accurate load planning before installation is important.
- What SFP modules are compatible with the 4 fibre ports, and are they included?
SFP modules are not included with the switch. The 4 SFP ports accept Gigabit SFP modules, but you must confirm compatible module types, fibre type (single-mode or multi-mode), wavelength, and operating distance before purchasing modules separately. Using modules not validated for this switch may result in link instability or no link at all.
- Is the DS-3T1512HP-SI/8P4F suitable for outdoor cabinet or enclosure installation?
Yes, the switch is designed for installation inside outdoor enclosures or industrial cabinets. Its metal IP40 shell, -40°C to 75°C operating temperature range, 6kV surge protection, and dual power input with hot backup make it appropriate for harsh outdoor or industrial environments, provided it is housed in a suitably rated enclosure that protects against direct water ingress.
- What does the PoE watchdog function do on this switch?
The PoE watchdog on Ports 1 to 8 monitors connected cameras and automatically restarts the PoE power supply to any port where a device stops responding. This helps recover cameras that have become unresponsive without requiring a technician to travel to the site and manually power-cycle the device, which is particularly useful for remote or hard-to-access installations.
- How is the DS-3T1512HP-SI/8P4F managed remotely, and what can be monitored or controlled?
The switch supports web-based management, Hik-Central Pro, and Hik-Partner Pro remote management. Through Hik-Partner Pro, authorised users can view port data rates, bandwidth utilisation, PoE power usage per port, network topology, active alarms, and can remotely restart individual ports or connected devices, enable long-range mode, and apply firmware upgrades without being on site. Security Wholesalers can advise on compatible Hikvision management platform licensing for professional deployments.
