PoE Switches Built for Camera Power, Not Office Devices
HRUI is a Chinese networking manufacturer headquartered in Shenzhen, specialising in PoE switches, industrial switches, and media converters. Their products carry CCC, CE, FCC, and RoHS certifications and are used in security, transportation, power, and industrial applications globally. HRUI is not a general-purpose IT networking brand: they focus specifically on PoE power delivery hardware designed for demanding, continuous-load environments.
Most IT professionals think of PoE switches in terms of powering office devices: IP phones, wireless access points, laptops. These devices draw power intermittently and at relatively low levels. CCTV cameras are fundamentally different: they draw power continuously, and at night the load increases significantly as infrared LEDs activate for low-light operation. A switch designed for office PoE may handle camera loads poorly over time: unstable power delivery, port failures under sustained load, or a single stuck camera port that takes down neighbouring ports. HRUI builds their switches for exactly this environment. That is why Securevision uses them at the downstream access layer of camera networks.
Securevision Scope
Securevision deploys HRUI PoE switches as the downstream access layer: directly powering IP cameras and intercom door stations. For remote management and aggregation above the HRUI switches, we pair them with Ruijie/Reyee or Omada managed switches at the distribution layer. HRUI switches currently do not support cloud management, so they are specified where reliable local PoE delivery is the priority and remote management is handled by the switch above them in the network stack.
Why Reliable PoE Power Matters More Than Most Integrators Realise
The switch that powers a camera is as important as the camera itself. Inconsistent or inadequate PoE delivery is one of the most common causes of camera reliability issues in the field: and one of the least discussed.
CCTV Cameras Need Heavy, Consistent Power: Especially at Night
A standard IP camera draws a predictable level of power during the day: processing, encoding, and transmitting video. At night, as the camera switches to infrared mode, the IR LED array activates and power draw increases significantly. This is not a brief spike: it is a sustained higher load for as long as the lighting conditions require it. In Singapore, where outdoor cameras operate in low-light conditions for many hours daily, this sustained draw is the normal operating state, not an exception.
A PoE switch that is not designed for continuous heavy load will deliver inconsistent power under these conditions: causing cameras to reboot, drop the network connection, or deliver degraded image quality without an obvious fault. HRUI switches are rated and tested for this sustained delivery profile. The difference between a camera that stays online reliably and one that intermittently drops is often the switch behind it.
PoE Watchdog: Auto-Reboot Without Human Intervention
Every HRUI AI PoE switch includes per-port PoE watchdog functionality. The switch monitors each connected device continuously. If a camera stops responding: a network hang, a firmware freeze, or a software fault: the watchdog detects the unresponsive state and automatically cycles power to that specific port, rebooting the camera without affecting any other port on the switch.
For Securevision, this has direct operational value. A camera that goes offline at 2am in a condominium car park or a factory perimeter would previously require either a site visit to power-cycle it or waiting until business hours for remote access. With PoE watchdog, the switch handles it automatically. The camera reboots, reconnects, and resumes recording: often without the client ever knowing there was a fault. This is one of the most practically useful features in a camera network, and it is built into every HRUI switch as standard.
Outdoor-Rated and Robust: Built for Security Environments
HRUI switches are rated for operation in demanding physical environments: wider operating temperature ranges, metal enclosures, and surge protection (4kV surge, 8kV ESD on selected models). For Securevision installations where switches are mounted in outdoor enclosures, exposed comms rooms, or industrial environments, this physical robustness matters. A switch that fails due to temperature variation or electrical surge in an exposed location means a section of cameras goes offline until a replacement can be sourced and installed.
Commercial office-grade switches are not designed for these conditions. HRUI's focus on security and industrial applications means their hardware is specified and tested for the environments where security cameras are actually deployed.
VLAN and Management: With One Honest Limitation
HRUI switches support VLAN segmentation, port isolation, QoS, and local web-based management: giving Securevision the network control needed for a properly designed camera network. VLAN configuration isolates camera traffic from other network segments, and port isolation prevents cameras from communicating directly with each other (a standard security configuration).
The honest limitation is cloud management. At this point, HRUI switches do not support a cloud management platform equivalent to Ruijie Cloud or Omada SDN. This means Securevision cannot monitor or manage HRUI switches remotely in the same way. For this reason, we deploy HRUI at the access layer: directly powering cameras: and use Ruijie/Reyee or Omada managed switches at the distribution layer above, where remote monitoring and management capability is most needed.
SECURE™ Integration
In a typical Securevision layered network, HRUI PoE switches sit at the access layer: powering cameras directly. Above them, a Ruijie/Reyee or Omada managed switch aggregates traffic and provides cloud visibility. When Securevision logs into Ruijie Cloud or Omada SDN remotely, the managed switch shows which upstream ports are active. The HRUI watchdog handles individual camera faults autonomously at the port level, reducing the volume of issues that ever need to reach the remote management layer.
HRUI Products in Securevision Installations
HRUI produces PoE switches across a range of port counts and power budgets. These are the configurations we typically deploy.
8-Port AI PoE Switch
The most common deployment size for a cluster of 4–6 cameras. 8 PoE ports plus 2 uplink ports. PoE watchdog on all ports. Used for a single building level, a perimeter section, or a small standalone site.
16-Port AI PoE Switch
For larger camera clusters: a full floor of a building, a condominium block, or a multi-zone commercial site. 16 PoE ports plus uplinks and SFP slot for fibre connection to the distribution switch above.
Hi-PoE Models (60W per port)
Selected HRUI models support Hi-PoE at up to 60W on specific ports: for PTZ cameras, high-powered intercoms, and any device that exceeds the standard 30W PoE+ limit. Specified when the camera selection includes Pan-Tilt-Zoom or motorised units.
When Do We Use HRUI vs Ruijie/Reyee or Omada?
The choice is not either/or: in most larger deployments, we use both in the same network.
HRUI at the access layer: Directly powering cameras and intercoms. Chosen for its continuous PoE delivery reliability, watchdog auto-reboot, and outdoor-rated hardware. No cloud management: does not need it at this layer because the switch above handles remote visibility.
Ruijie/Reyee or Omada at the distribution layer: Aggregating traffic from multiple HRUI switches, connecting to the NVR and core network, and providing cloud management for remote monitoring and diagnosis. When Securevision logs in remotely to check a site, this is the switch we are looking at.
When HRUI is deployed alone: For smaller sites: 4 to 8 cameras: where remote cloud management is not a requirement and the client simply needs reliable camera power without the cost of a managed distribution switch. In these cases, the HRUI's local management interface is sufficient for the occasional configuration change.
When Ruijie/Reyee or Omada is used without HRUI: Where the project is small enough that a single managed switch covers both the access and distribution function, and where remote management is a specific requirement from the outset.
