If it's the sole switch, connect it straight to the router. But if you're trying to access cameras via the router's WiFi or from another port, it may slow things down on the 100Mbit port when many are used at once. For a WiFi issue, set up a separate WiFi access point connected to the switch. If it's a wired client problem, both devices should be inside the switch to avoid restrictions. Upgrading to a faster router should resolve the speed concerns if your internet needs exceed 100Mbit.
The cameras transmit a compressed signal, the speed will vary based on resolution and codec selected... I’d estimate around 10-40 Mbps per camera. If the NVR offers two gigabit Ethernet ports for cameras, you could use a pair of 16-24 port gigabit switches. Alternatively, a single 48-port switch would suffice. Placing twelve cameras on a 16-port switch means even with a 50 Mbps camera rate, you’d reach 600 Mbps total—well within the 12 x 50 Mbps limit. With one switch, aim for under 30 Mbps per camera, since 32 cameras at 30 Mbps would equal 960 Mbps, ensuring the port can handle it.
If you aim to link 32 cameras, you'll need a minimum of 32 ports. A 16-port switch will only accommodate 15 cameras plus one for the NVR, limiting you to about 30 devices. For better performance, opt for a switch with at least 24 ports or more. You might connect one switch to the router using a free port if you need external access to the NVR—configure port forwarding accordingly. Avoid routing camera traffic through the router; instead, link cameras directly to the switch. Consider PoE switches to power your cameras via Ethernet cables, which can help manage power needs. Higher port counts are often better since they provide more capacity and support additional power options. For instance, with 16 cameras on a switch, the power draw could reach 160 watts; a 16-port PoE switch might only offer 90 watts, whereas a 24-port model could handle 200–250 watts. If each camera uses around 10 watts, a 16-port switch would have a limited 120-watt PoE budget, while a 24-port model may provide a 200–250-watt range. For example, the TP-Link TL-SG116P offers 120W PoE and is suitable for this setup: https://www.amazon.com/TP-Link-TL-SG116P...B0C4X7VZV9. If budget allows, a 24-port switch with sufficient power can simplify management. Alternatively, you could look at refurbished options for cost savings—like the used HPE/Aruba device mentioned, which offers good value for 48 x 100 Mbps ports and PoE support.
wow, thank you for all the info, when i say 16 ports i mean the ones with 2 extra uplink ports, like this one: https://www.aliexpress.com/item/32887512145.html
