The Mars Security system has a number of unique features:
1. Operates throughout all parcels owned by you on a region and is not limited to the usual crude & inefficient 96m scanner. This means if you own a whole region or several disconnected parcels on a region then it is possible to police it all with just one instance of this system.
2. It will only scan the owners parcel and so will not accidentally attack innocent visitors. If you have several disconnected parcels on a region this is ok - all are scanned.
3. Unlike other "orb" systems which scan based on a radius from the controller this system works on absolute region coordinates by recording just two points diagonally opposite one another (eg: <10,20,100><50,60,300> is a cube with dimensions 50-10 x 60-20 x 300-100 or 40 x 40 x 200, the whole region is <0,0,0><255,255,4095>). Note it does not matter if the area you specify is beyond your borders as the scanning will be restricted to just your parcels.
4. Multiple zones may be monitored (eg: several distinct rooms) within the owner's parcel(s) all from just one instance.
5. You may have several instances of the system controller on your parcels providing different access to each area policed.
6. Controller is both Menu and settings notecard driven. Only exception is the specification of time out periods, warning messages & zones policed.
7. Ability to add / delete users or administrators by menu or within the settings notecard
8. Ability to add users temporarily as visitors which expires after a preset time interval.
9. Actions may be none, ejecting from land, teleporting home and/or banning temporarily or permanently
10. Warnings to intruders are given and there is a grace period which may be set so they have time to move away. This is important for users overflying your land and adheres to Linden TOS guidance.
11. Warning message is changeable within the settings notecard
12. Owner has the option of being informed of intruders / changes made by their administrators
13. System displays current status and who is within one of the zones / being warned in real time. This may be disabled.
14. Optional security badges may be given out which can add temporary access without the need for an administrator when required.
This is all currently achieved with just one optimised low impact script using Linkset Data which permits up to 128Kb of user data.
Notes:
a) You must own the land you rez this on as the eject/ban processes will otherwise not be enabled and silently fail (see below).
b) TOS requires that sufficient warning is given to people overflying your land (may not apply on private regions). Otherwise it may be considered griefing.

Ownership Limitations:
* If the land under the object is owned by an individual, the script must be owned by the same individual.
* If the land under the object is deeded to a group the object will need to satisfy one of the following:
* The object is deeded to the same group.
* The object owner must have "Eject and freeze Residents on parcels" ability in the group and be connected to the sim
- Protects all your private areas (up to region wide)
- Zone system allows setting multiple protected areas
- No attacking avatars on other people's land
- Permitted users, admins, temp users, badge wearers
- Action for intruders after warning period: none, eject, send home, ban
Excellent!
It takes a little work, but perfect if you want to create different areas for security that don't follow the usual range/radius areas.
The menu is good, and it works well. Perfect for smaller spaces or whole sims that want an exclusive zone.
