Difference Between Hikvision DS-3E1510P-EI and DS-3E1510P-SI
The Hikvision DS-3E1510P-EI and DS-3E1510P-SI are both 8-port Gigabit smart managed PoE switches, commonly used in IP surveillance and networking. While they are similar in design and core function, they have key differences:
1. Uplink Port Type:
-
DS-3E1510P-EI: 2 × Gigabit RJ45 uplink ports
-
DS-3E1510P-SI: 2 × Gigabit SFP fiber optic uplink ports
This makes the SI version more suitable for longer distance backbone connections via fiber.
2. MAC Address Table:
-
DS-3E1510P-EI: 4K MAC address entries
-
DS-3E1510P-SI: 8K MAC address entries
Larger MAC table in the SI model supports more connected devices in complex networks.
3. Internal Packet Buffer (Cache):
-
DS-3E1510P-EI: 1.5 Mbits
-
DS-3E1510P-SI: 4.1 Mbits
Greater buffer in the SI model can help reduce packet loss during high traffic.
4. Operating Temperature Range:
-
DS-3E1510P-EI: 0°C to 40°C
-
DS-3E1510P-SI: -10°C to 55°C
The SI version is more rugged, suitable for harsher environments.
Summary: Choose the DS-3E1510P-EI for general use in standard indoor environments with RJ45 uplinks. Opt for the DS-3E1510P-SI if you need fiber uplinks, higher performance in terms of device count, or environmental durability.
