Blocks and Screens
Every NeroSecurity block and item, what its tooltip says, how it is made, and what each screen shows. All recipes use vanilla materials.
| Block | Tooltip | Use | Sneak-use |
|---|---|---|---|
| Security Hub | Controls one installation: who is a member, what is linked, lockdown. | Opens the hub screen (OFFICER) | — (an owner breaks it while sneaking to dissolve the installation) |
| Keycard Programmer | Writes, copies and wipes keycards for the installation it is linked to. | Opens the programmer (MEMBER) | — |
| Security Door | A powered 1×2 door that opens only for the access level you set. | Opens or closes | Opens its settings (OFFICER) |
| Blast Door | A powered 2×2 door with heavier plating. Same rules as the security door. | Opens or closes | Opens its settings (OFFICER) |
| Secure Chest | A chest that checks access on open and only lets automation in when the installation allows it. | Opens the chest | Opens its settings (OFFICER) |
| Laser Grid Node | Pairs with a facing node and raises an alarm event when someone not permitted crosses the beam. Needs power. | Opens its settings (OFFICER) | — |
| Security Camera | Watches a cone in front of it and raises an alarm event for anyone not permitted. Senses presence only; it never records images. | Says whether it is armed | Opens its settings (OFFICER) |
| Security Monitor | Shows the installation's cameras, lasers and recent events as text. | Opens the monitor (MEMBER) | — |
| Alarm | Reacts to security events: redstone, sound, light, a chat message — and, if the owner allows it, lockdown. | — | Opens its settings (OFFICER) |
| Force Field Emitter | Projects a wall or shell of field blocks that permitted players walk through and everyone else cannot. Needs power; overloads under fire. | Opens its settings (OFFICER) | — |
| Force Field | Solid to anyone not permitted, to mobs, projectiles and vehicles — mounted players included. | Placed only by an emitter | — |
The levels in brackets are the lowest level that may do it, at the device's own installation. A device that is not linked to an installation has no owner: doors and chests are public, sensors and emitters do nothing.
Every device except the hub and the force field can be broken by anyone. Breaking a device you could not use is logged as forced.
| Item | Tooltip |
|---|---|
| Linking Tool | Sneak-use on a hub to select it, then use on a device to link it. |
| Keycard | Blank — encode it at a keycard programmer. (A written card shows its level, serial and whether it is bound; an encrypted one only says it is encrypted.) |
| Encryption Module | Fit to a keycard programmer to write and copy encrypted keycards (owner only). |
| Hardness Module | Fit to a door: harder to break and more blast resistant. |
| Open-Speed Module | Fit to a door: opens and closes faster. |
| Range Module | Fit to a laser node or camera: +4 blocks of range. It also adds 4 blocks of range to a force field emitter. |
| Strength Module | Fit to an emitter: +1 strength (more load before overload, more power). |
All are shaped crafting recipes except the keycard. . is an empty slot.

Every screen has a one-line title and a subtitle that says what it is for. Buttons you cannot use are greyed out, and hovering over them says why. The bottom line of each screen shows what just happened, or why the server refused.
The title is the installation's name; an owner can rename it with the pencil button. The subtitle reads "Who can get in, what is linked, and what happened." STATUS shows whether the installation is normal or in lockdown, how many devices are linked and how many are working, and your own level with what it means. LOCKDOWN holds one large button: "LOCKDOWN IS OFF — TURN ON" or "LOCKDOWN IS ON — TURN OFF", with "Seals doors, fields to max, only the OWNER gets in." beneath it. Every press asks you to confirm. After an alarm lockdown an owner sees "LOCKDOWN (ALARM) — CONFIRM" and a smaller "Clear lockdown" button. MEMBERS lists owners first, then members with their level; + Add, ▲ Promote, ▼ Demote and – Remove manage them. DEVICES lists every linked device with its position and state (unpowered, unpaired, idle, not loaded, sealed); to unlink one, sneak-use the Linking Tool on it. LAST 5 EVENTS shows the newest events as sentences, in the same words as the monitor. Reading the hub is not logged as a log read.
Titled "Privacy — what installation records", with the subtitle "Who did what, where and when. Never
items, chat or pictures." WHAT IS KEPT shows how long the audit log keeps entries on this server,
whether cameras are on and whether they log members (in amber when they do), who can read the log
("OFFICER and above. Every read is itself logged.") and the area notice. YOUR DATA ON THIS SERVER
has three buttons: Export my data, Stop naming me (or Name me again) and Erase my data….
Erase asks you to confirm, then opens chat with /neroland data eraseme filled in; you press Enter to
run it. See Privacy.
Titled "Write a keycard", with the subtitle "Pick a level, press Write. The card opens whatever allows that level." On the left are the Card, Blank and Module slots. On the right is the level ladder with the meaning of the chosen level, the Encrypted and Bind to me switches, and a coloured band that previews the card you are about to write. Below are Write, Copy and Wipe, and the count "Cards issued: n / 512". See Keycards.
Titled "Who can open this door?", with the subtitle "Anyone at this level or higher. Lockdown always needs the OWNER." It has the level ladder and its meaning, Keycard only ("Ignore membership: only a keycard at this level opens it. You can always sneak-use it to turn this off."), Opens while powered by redstone when the server allows it, the power bar, and status lines: which installation it is linked to (or "Not linked to any installation — anyone can use it."), and whether it is sealed by lockdown or unpowered. The UPGRADES box holds the Hardness and Open-Speed Modules. Changes save at once.
Titled "Who can open this chest?", with the subtitle "Hoppers and pipes count as 'automation' and follow the installation's rule." It has the level ladder, Keycard only, and the line "Automation: off / MEMBER / OFFICER" with a dot that shows whether automation can reach this chest and why not: "off for this installation", "this chest's level is above the automation level", "keycard-only chests never allow automation" or "blocked during lockdown". It also shows the command an owner uses to change the policy.
Titled "Who may cross this beam?" for a laser and "Who may pass this camera?" for a camera, with the subtitle "Anyone below this level raises an alarm event. Permitted people are not logged." It has the level ladder, Also sense (players only, players and hostile mobs, every living thing), Field of view (60°, 90°, 120°, cameras only), the power bar, the UPGRADES box for Range Modules, and a status line: "Armed — recording active", "Not armed — no power", "No facing node within range" or "Not linked — senses nothing". When the server has switched cameras off, an amber line says so.
Titled "What should this alarm do?", with the subtitle "Tick what it listens for on the left and what it does on the right." The left column, WHEN THIS HAPPENS, lists the events in three groups: Breaches, Denied access and System. The right column, DO THIS, lists Redstone pulse, Sound, Light, Message owner/officers and Trigger lockdown. Trigger lockdown is greyed out unless you are the owner, and a warning explains that an alarm lockdown locks out everyone but the owner for a few minutes, then clears itself. At the bottom are Silence 10 min, the time left on a silence, and whether the alarm is armed. Ticks save at once.
The title is the installation's name and its status. The subtitle reads "Sensor status and recent events, as text. No pictures are ever kept." The left half lists the installation's cameras and laser grids with their state; the right half lists recent events as sentences such as "Laser grid tripped — a player at 15, 65, -3, 2 min ago". It never names who. Refresh updates it. Amber lines appear when the server has switched cameras or the audit log off.
Titled "Who can walk through this field?", with the subtitle "Permitted people pass. Everyone and everything else is stopped." It has the level ladder, Field on, Keycard only, Shape (wall or shell), and steppers for Distance, Width, Height and, for a shell, Depth. Below are the power bar, the Load bar (how close the field is to overloading), the UPGRADES box for Strength and Range Modules, and a status line such as "Projecting — strength 2/5, 25/25 blocks, 12/t, load 18%", "No power", "Overloaded (42 s)" or "Idle". During a lockdown it reads "Projecting at maximum — lockdown". If the shape does not fit, an amber line says why, for example "Too large for this emitter's range (12)."
