POWER & NETWORKING
PoE Switches for CCTV Systems
Six models, 8 to 24 PoE ports, IEEE 802.3af/at, 48-55V output and a one-key extend mode that reaches 250m. One cable per camera carries power and video — the switching layer that makes a PoE camera system install cleanly.
Model comparison
All figures below come from the manufacturer spec sheet for each model. Choose by port count first, then by uplink type and power budget.
| Model | PoE ports | Rate | RJ45 uplink | SFP | Power | Backplane |
|---|---|---|---|---|---|---|
| PS082 | 8 | 10/100M | 2 | — | DC 52V 120W | 8.8Gbps |
| 1011GB | 8 | 10/100M | 2 | 1 | DC 52V 120W | 7.6Gbps |
| PS162 | 16 | 10/100M | 2 | — | DC 52V 250W | 7.2Gbps |
| 16F21GB | 16 | 10/100M | 2 | 1 | DC 52V 250W | 9.2Gbps |
| 24G02GS-P | 24 | 10/100/1000M | — | 2 | DC 52V 320W | 52Gbps |
| PS242 | 24 | 10/100M | 2 | — | DC 52V 320W | 8.8Gbps |
Which switch for how many cameras
4-8 cameras
PS082 / 1011GB (8 PoE ports)
Power budget: 120W
A single run of small cameras; 120W covers eight full-colour units with headroom.
9-16 cameras
PS162 / 16F21GB (16 PoE ports)
Power budget: 250W
One floor or one building wing; 250W keeps fill-light cameras inside budget.
17-24 cameras
PS242 / 24G02GS-P (24 PoE ports)
Power budget: 320W
Hotel floor or warehouse zone; the all-gigabit version handles 5MP streams without contention.
25+ cameras
Stack several switches, one per zone
Power budget: per-switch
Zone-level switching keeps cable runs short and isolates a fault to one floor.
What every model shares
802.3af/at
Standard PoE
Powers IP cameras and access points over the same cable that carries data — no separate power runs.
250m
Extend mode
One-key DIP switch drops ports to 10Mbps and pushes transmission to 250m for long outdoor runs.
VLAN
Port isolation
The same DIP switch isolates camera ports from each other — cuts broadcast storms in CCTV networks.
52V
Internal power
AC 110-240V input with internal DC 48-55V output; no external power brick on the rack.
Plug & play
Unmanaged
No software, no configuration — cameras come up as soon as they are plugged in.
1U
Rack / desk
Metal housing built for a cabinet or a shelf; wall-mount ears included on the 8-port models.
