UNV NSW2020-16T1GT1GC-POE-IN 18-Port 250W PoE Switch with Gigabit Uplinks

The switch includes 16 × 100 Mbps PoE ports with RJ45 connections, so it is built to support up to 16 PoE-powered edge devices such as IP cameras. In addition to those downlink ports, it also includes 1 × 1000 Mbps Gigabit Ethernet port and 1 × 1000 Mbps combo port for uplink connectivity. That layout makes it especially practical for surveillance systems where multiple cameras need centralized power and data from one switch. For buyers building a medium-size camera network, this gives a straightforward port count without needing extra PoE injectors. 

According to the datasheet, the maximum PoE capacity is 250 W for the whole switch. It also states the maximum capacity for a single port is 30 W. That means the switch is designed to power a mix of standard PoE and PoE+ devices within that overall budget. For buyers, this is important because it helps determine how many cameras or other powered devices can be connected at the same time without overloading the switch.

Yes, the datasheet says the switch supports up to 250 m transmission distance in surveillance mode, which is also labeled as EXTEND mode. That feature is intended for surveillance-focused deployments where cameras may be located farther away than in a typical office network layout. The same document also explains that in Extend mode, downlink ports can communicate only with uplink ports. For users planning longer cable runs in camera systems, this is one of the most important reasons to choose this model.

The VLAN mode is described in the datasheet as Secure mode. In this mode, downlink ports can communicate only with uplink ports instead of freely communicating with each other. The datasheet also says that when PD keepalive is enabled, the switch will restart the IPC through PoE power if the IPC sends no message for a period of time. That makes Secure mode useful in surveillance networks where port isolation and camera stability are both important.

This model provides 1 × 1000 Mbps Gigabit Ethernet port and 1 × 1000 Mbps combo port in addition to its 16 PoE downlink ports. Those uplink options are useful for connecting the switch back to a recorder, core switch, or network backbone without using one of the PoE camera ports. The datasheet identifies the product as a Layer 2 switch with these dedicated uplink connections. For buyers, that matters because it helps keep camera ports available for powered devices while still giving faster upstream connectivity.

The datasheet strongly points to surveillance use because one of its three operating modes is specifically called EXTEND, or Surveillance mode. It also supports up to 250 m transmission distance in that mode, secure port behavior in VLAN mode, and PD keepalive behavior for IPC restart when communication is lost. Those are all features that align closely with camera deployments rather than simple desktop networking. While it is still an Ethernet PoE switch, its feature set is clearly optimized for surveillance environments.

The switch supports IEEE 802.3af and IEEE 802.3at PoE standards, according to the datasheet. It also lists PoE mode as ModeB (4578). That means it is designed to work with common PoE and PoE+ devices that follow those standards. For buyers using surveillance cameras or other compatible powered devices, that gives a clear baseline for compatibility planning.

The datasheet lists the dimensions as 440 × 195 × 44 mm and the weight as 2.12 kg. It also specifically says the unit uses an all-metal housing and describes that build as safe and reliable. The dimension drawing on page 3 visually confirms the overall chassis size and shape. For installers, this helps when planning shelf space, enclosure fit, or rack-area placement.

The switch includes a PoE-MAX indicator for that purpose. The datasheet says the indicator stays off when the whole-machine PoE power is below 80% of the specification, and it stays on when PoE power is above 85% of the specification. It also includes POWER, PoE, and LINK/ACT indicators for AC input status, PoE supply status, and data link activity. That gives users a quick visual way to monitor operating status without logging into a management interface.

Yes, the datasheet includes a compliance line that states “NDAA Compliant Support.” That is an important detail for buyers working on projects where procurement rules or customer requirements call for NDAA-aligned equipment. It is listed directly in the specifications rather than being implied elsewhere in the document. For government-related, education, or regulated projects, that line can be especially relevant during product selection.
