| Attribute | Jemii-150 Series (Jemii-150D-PoE / Jemii-150A-PoE / Jemii-150A) | RTSO-6003-VP3.0 |
|---|---|---|
| PoE standard | 802.3af, 802.3at, 802.3bt Type 3, 802.3bt Type 4 | 802.3af, 802.3at |
| PoE ports | 4 PoE GbE | 4 PoE GbE |
| Total Ethernet ports | 5 (1GbE) | 5 (1GbE) |
| PoE total budget | 100 W | not listed in the catalog |
| Power input | Jemii-150D-PoE: 9V to 32V DC input; Jemii-150A-PoE: ATX power + PCIe 6-pin; Jemii-150A: ATX power | 19–52 V |
What this means for your NVR:
- PoE standard: The Jemii-150 Series supports the wider range — up to 802.3bt Type 3 and Type 4 (high-power PoE) in addition to 802.3af/at — while the RTSO-6003-VP3.0 tops out at 802.3at. neousys-te... +1neousys-tech.com ↗“802.3af, 802.3at, 802.3bt Type 3, 802.3bt Type 4”realtimesai.com ↗“power.poe_class=802.3af, 802.3at”
- PoE port count: Both offer 4 PoE GbE ports (with a 5th non-PoE GbE port each), so the port count is even. neousys-te... +1neousys-tech.com ↗“io.poe_port_count=4”realtimesai.com ↗“io.poe_port_count=4, io.ethernet_ports=5”
- Power input: The Jemii-150 Series splits by model — the Jemii-150D-PoE runs on 9V–32V DC, while the Jemii-150A-PoE and Jemii-150A use ATX power (the A-PoE adding a PCIe 6-pin connector). The RTSO-6003-VP3.0 accepts 19–52 V, which suits vehicle/battery-backed deployments better than the Jemii-150D-PoE's lower DC ceiling. neousys-te... +1neousys-tech.com ↗“ATX power”realtimesai.com ↗“19-52 V”
One note: on the Jemii-150 Series, PoE is listed as an optional capability in the catalog, so confirm PoE is included in the specific configuration you order. A total PoE budget of 100 W is stated for the Jemii-150 Series; the RTSO-6003-VP3.0's total PoE budget is not listed in the catalog, so if powering multiple high-draw cameras off the RTSO-6003 you'd want to verify that budget with the manufacturer (Realtimes). neousys-te... +1neousys-tech.com ↗“power.poe_optional=True”neousys-tech.com ↗“power.poe_total_budget_w=100 W”
Both are carrier boards: the Jemii-150 supports Jetson Orin NX/Nano modules, and the RTSO-6003-VP3.0 supports Orin NX/Orin Nano/Xavier NX. neousys-te... +1neousys-tech.com ↗“compatibility.jetson_module=Jetson Orin NX 16GB”realtimesai.com ↗“Jetson Orin NX/Orin Nano/Xavier NX”
