Hikvision DS-3E1505P-EI/M 4-Port Gigabit Smart Managed PoE Switch with 45W PoE Budget, 300m Long-Range Transmission and 6kV Surge Protection... 2 years warranty
 
Overview
The Hikvision DS-3E1505P-EI/M is a compact smart managed Gigabit PoE switch designed for surveillance systems, professional networks and installations requiring centralised power and data transmission.
 
It provides four Gigabit PoE ports and one Gigabit RJ45 uplink port, with a total PoE power budget of 45W. Each PoE port supports IEEE 802.3af and IEEE 802.3at devices, with up to 30W available per port.
 
The switch supports remote monitoring and management through Hik-Partner Pro, Hik-Central Pro and its built-in web interface. Installers can view network topology, port status, bandwidth usage, PoE consumption and device alarms, as well as restart connected ports and devices remotely.
 
Its PoE Watchdog function automatically detects and restarts compatible cameras that stop responding, while cable diagnostics, VLAN management, port isolation and loop-prevention functions help improve network reliability and simplify troubleshooting. 
 
Key Features
 
Four Gigabit PoE Ports
The DS-3E1505P-EI/M includes four Gigabit RJ45 ports capable of transmitting both data and electrical power to compatible PoE devices through a single network cable.
 
The switch is suitable for connecting compatible:
IP surveillance cameras;
video intercom devices;
wireless access points;
other IEEE 802.3af or IEEE 802.3at powered devices.
 
Dedicated Gigabit Uplink
A fifth Gigabit RJ45 port provides the uplink connection to a router, recorder, network switch or other compatible network device.
 
45W PoE Power Budget
The switch provides a total PoE budget of 45W, with a maximum power output of 30W per port.
The actual number and type of devices that can be powered simultaneously depend on their combined power requirements.
 
Up to 300m Long-Range PoE Transmission
Long-range mode supports PoE data and power transmission over distances of up to 300m on ports 1 to 4.
The manufacturer specifies that actual long-range performance may vary according to the connected camera model and the condition or quality of the network cable. 
 
PoE Watchdog
The PoE Watchdog function monitors devices connected to ports 1 to 4. When a connected camera stops responding, the switch can automatically restart the relevant PoE port to help restore operation without requiring an on-site intervention.
 
802.1Q VLAN Management
The switch supports IEEE 802.1Q VLAN configuration, with:
VLAN IDs from 1 to 4094;
Access and Trunk port modes;
up to 32 VLANs.
VLANs can help separate network traffic, organise connected devices and improve network security.
 
Port Isolation
Ports 1 to 4 can be placed in an isolation group. Devices within the isolated group cannot communicate directly with each other but can communicate with ports outside the group.
 
This can help reduce unwanted communication between connected devices and improve surveillance-network security.
 
Loop Prevention
The switch supports:
IEEE 802.1D STP;
IEEE 802.1w RSTP.
 
These protocols help prevent network loops that could otherwise disrupt or seriously affect network communications.
 
Cable Detection and Diagnostics
The integrated cable-detection function can identify:
open circuits;
short circuits;
approximate network cable length.
 
This function helps installers locate cable faults and simplify network troubleshooting.
 
Link Aggregation
The switch supports one static link-aggregation group, allowing compatible physical ports to be combined into a logical connection for bandwidth expansion, load balancing or port protection.
 
Remote Management with Hik-Partner Pro
Hik-Partner Pro provides one-click activation and remote-management functions, including:
port-rate monitoring;
bandwidth-utilisation monitoring;
PoE power-usage monitoring;
network-topology display;
alarm-status display;
remote restart of ports and connected devices;
remote activation of long-range mode;
remote firmware upgrades.
 
Web and Hik-Central Pro Management
The switch can also be managed through its web interface and Hik-Central Pro.
 
Additional system-management functions include:
DHCP Client;
fixed Super IP address at 10.180.190.200;
IEEE 802.1ab LLDP device discovery;
port mirroring for troubleshooting.
 
6kV Surge Protection
The switch provides 6kV surge protection to help protect the device against electrical surges in compatible installations.
 
Proper grounding and suitable installation practices remain essential for effective protection.
 
Compact Metal Housing
Its compact metal enclosure supports both desktop and wall-mounted installation, making it suitable for small network cabinets, offices, retail stores and surveillance installations.
 
Conclusion
The Hikvision DS-3E1505P-EI/M offers a strong balance of compact size, Gigabit performance and smart network-management features.
 
Its four Gigabit PoE ports, dedicated Gigabit uplink, 45W PoE budget and 300m long-range mode make it suitable for small and medium surveillance installations.
 
PoE Watchdog, cable diagnostics, VLANs, port isolation, loop prevention and remote management through Hik-Partner Pro provide additional control and can reduce the need for on-site troubleshooting.
