Sylcurity
by sylvxa
Sylcurity is a Fabric security mod for servers, with security terminals, cameras, player detectors and event devices that link through access groups.
What it does
Players open a security terminal to reach a GUI that shows cameras and the network they belong to. Every device stores its own roster of trusted players, and only those players may operate it or pass through its area. A terminal's activity log records events across the network, including for chunks that are loaded.
Devices communicate by sending and receiving events within access groups. A player detector acts like an invisible tripwire with a 32-block range and 16 rotation states for the angle it faces, and it emits a Player Detection event when someone enters its line of sight. An event receiver turns a received event into a redstone signal. Cameras give long-range visual monitoring, but only while their chunk is loaded. Polymer is bundled inside the mod, and Fabric API is required.
Key features
Security terminal and activity log
The terminal opens a GUI for cameras and the network, and its activity log keeps track of events across loaded chunks.
Cameras with a stand-in
A player using a camera is teleported into a fake spectator state while an NPC stands in place, and crouching exits the view.
Player detector
A tripwire-style block with a 32-block range and 16 facing angles that emits a Player Detection event when someone is in sight.
Event devices and groups
Devices send and receive Security Access and Player Detection events within their groups, and an event receiver can emit a redstone signal.

Use cases
Who it’s for: Server owners who want access-controlled devices and event links between them. Players on Bedrock through Geyser may find the camera and dialog behavior limited, because of differences in spectator mechanics and Bedrock form limitations.

What the author says
Simply drop this mod into the mods folder and it will work as expected. However, custom textures for the Event Receiver (and future textured blocks/items) can be applied by also installing Polymer and configuring resource pack hosting. The mod should work fine with Geyser players once 1.21.6 is released, though…
