16-Port Gigabit PoE for CCTV Security Cameras

The DS-3E1518P-SI provides 16 Gigabit PoE ports, allowing compatible CCTV cameras to receive both network data and electrical power through a single Ethernet cable.

Instead of installing:

Power Cable + Network Cable

a PoE installation can use:

One Cat6 Cable = Power + Network Data

This simplifies CCTV installation and reduces the number of separate power adapters required near cameras.

It is ideal for:

• HIKVISION IP Cameras
• AcuSense Cameras
• ColorVu Cameras
• Smart Hybrid Light Cameras
• AI Deep-Learning Cameras
• Fixed Dome Cameras
• Bullet Cameras
• Compatible PTZ Cameras
• Door Access Devices
• IP Video Intercom
• Wireless Access Points

225W PoE Power Budget

The DS-3E1518P-SI provides a total 225W PoE budget, with individual PoE ports supporting up to 30W.

Before connecting 16 cameras, technicians should calculate the total maximum camera power consumption.

For example, a system containing standard fixed IP cameras may comfortably operate within the available budget, while high-power PTZ cameras, heaters or other PoE+ devices can consume significantly more power.

Professional CCTV design should always consider:

Number of Cameras + Maximum Wattage per Camera + Total PoE Budget

Up to 300 Metres Long-Distance PoE

One of the most useful CCTV features is Long Range / Extend Mode.

Hikvision specifies transmission of up to 300 metres on ports 1–16 under supported conditions.

This can be extremely useful for:

• Factories
• Warehouses
• Car Parks
• Construction Sites
• Schools
• Large Compounds
• Industrial Plants
• Long Corridors
• Perimeter CCTV
• Remote Guardhouses

Actual long-distance performance depends on the connected camera, cable quality and installation conditions.

PoE Watchdog – Automatically Restart Offline Cameras

The PoE Watchdog function can automatically detect cameras that stop responding and restart the associated PoE connection.

This is particularly useful for 24/7 surveillance systems.

Instead of immediately sending a technician onsite simply to power-cycle an unresponsive IP camera, the switch can attempt to recover the device automatically.

This can help reduce:

• CCTV Downtime
• Manual Reboots
• Maintenance Calls
• Troubleshooting Time
• Camera Offline Duration

2 × Gigabit SFP Fibre Ports

The DS-3E1518P-SI includes 2 Gigabit fibre optical ports, allowing the switch to be connected through compatible SFP modules and fibre optic cabling.

Fibre is particularly useful for:

• Building-to-Building CCTV
• Factory Networks
• Long-Distance Backbone
• Server Room Connections
• NVR Network Connections
• Remote Security Buildings
• Electrical Noise Environments

A typical architecture can be:

16 IP Cameras → DS-3E1518P-SI → SFP Fibre → Main Server Room → NVR

VLAN for CCTV Network Segmentation

The switch supports VLAN configuration, allowing CCTV devices to be separated logically from other network services.

For example:

VLAN 10 – Office Computers

VLAN 20 – CCTV Cameras

VLAN 30 – Door Access

VLAN 40 – Wi-Fi

VLAN 50 – Network Management

Proper VLAN configuration can improve network organisation, security and troubleshooting.

Port Isolation for Better Security

Port Isolation allows selected camera ports to be prevented from communicating directly with one another while maintaining communication with the required uplink or NVR.

This can help strengthen CCTV network segmentation and reduce unnecessary device-to-device traffic.

6kV Surge Protection

The DS-3E1518P-SI provides 6kV surge protection on PoE ports.

This provides additional protection for professional CCTV infrastructure against electrical surge conditions.

For outdoor CCTV installations, proper earthing, surge protection and installation practices should still be implemented according to site requirements.

Ideal Applications

• Office CCTV
• Factory CCTV
• Warehouse CCTV
• Condominium CCTV
• Commercial Buildings
• Schools
• Hospitals
• Hotels
• Shopping Centres
• Car Parks
• Construction Sites
• Industrial Plants
• Government Facilities
• Server Rooms
• Enterprise Security Systems

CCTV Switch Troubleshooting Singapore

Many CCTV failures are actually caused by the underlying network or PoE infrastructure rather than the camera itself.

Common problems include:

• Camera Offline
• Camera No Power
• PoE Port Failure
• NVR Cannot Find Camera
• Intermittent Video
• Network Packet Loss
• SFP Fibre Link Failure
• Cat6 Cable Failure
• IP Address Conflict
• Network Loop
• VLAN Configuration Error
• Insufficient PoE Budget
• Remote Viewing Failure

Professional troubleshooting should examine the complete connection:

IP Camera → Cat6 Cable → PoE Switch → SFP/Fibre/Uplink → Network → NVR
