Multiple PoE switches and NVRs available for your setup.
You're checking for PoE switches and NVRs that can handle over 30 IP cameras simultaneously. It's possible to use two 24/16 port PoE switches connected to a single 30+ port NVR, allowing you to manage the cameras efficiently. For recording data, consider servers with sufficient ports—ideally more than 30—to accommodate your camera setup and management needs.
Search for a 48-port switch supporting around 1100 watts of PoE, which means each port can handle roughly 30 watts maximum.
I noticed the issue now. The project I'm working on is quite distant, so I had to secure the more costly items first, such as the PoE switch, while cameras will be added later. I also realized that a 48-port setup is preferable because it's more affordable and widely available.
It appears many cameras consume around 15 watts, but this figure might not reflect the latest technology.
It varies by device. A regular camera without heating uses about 10-11W, though this can change by brand. The Poe+ model draws more power. You should identify the specific cameras you have. If only indoor ones exist, an AF POE switch works well. For outdoor or speed dome setups, you might need to adjust to meet PoE standards.
It seems you'll need to consider cabling as well, since analog cameras typically use coax cables. You might want to switch to cat5/6 or check for cameras/NVRs that support digital over coax. POE can also be sent via a coax cable with converters at each end—something I used with Axis before. There could be more affordable options available. The lesson here is to do your research before making a purchase. I always test things out first before committing, because many surprises come up that way.
I received some guidance about exploring the area, as I’m not part of any organization but rather a student doing practice. They mentioned plans to switch from coax to IP cameras, which means rewiring will be necessary and new equipment will need installation where none existed before. I won’t be placing orders; everything will be provided by them. I’m just looking for the best gear suited for the situation. Also, a quick question—can you really run an NVR with both coax and IP cameras at the same time?
There are options available that fit these needs. I’ve noticed NVRs with one Ethernet port that could handle a specific count of IP cameras depending on their specs, plus around eight coax inputs. Be mindful with newer models to confirm they support analog video, as the market has shifted toward digital video over coax (besides IP cameras). Some devices even have coax ports that only accept digital signals.
EDIT: For switch recommendations, ensure you choose one with at least a smart interface—ideally a managed switch with an SSH-capable web interface or better. A basic switch won’t let you reboot cameras remotely, which is often necessary for IP systems but less so for analog ones.
