Surveillance under Surveillance

Surveillance under Surveillance shows you cameras and guards — watching you — almost everywhere. You can see where they are located and, if the information is available, what type they are, the area they observe, or other interesting facts.

Different icons and colors give you a quick overview about the indexed surveillance entries. Click on those icons on the map to get the available information.

Icon	Description
	Fixed camera — usually observing a limited area
	Dome camera — usually observing a 360° area
	Guard — e.g. an employee of a security service
	ALPR — Automatic Licence Plate Recognition

Color	Description
	Red background — observing a public outdoor area, accessable by everyone
	Blue background — observing a private outdoor area, accessable only by authorized persons
	Green background — observing an indoor area
	Yellow icon — camera or guard marked with a fixme key because it needs further attention

Installation

If you like to run Surveillance under Surveillance on your own LAMP or LNMP server follow these steps:

Get the sources

Copy the content of home/sunders/ to your home directory, e.g. to ~/sunders/.
Copy the content of www/sunders/ to your server's www directory, e.g. to /var/www/sunders/.

Set up the datebase

Change to the directory ~/sunders/init_cameras/db/.
Open the file createDB.sql and enter a password for the new database user camera.
Create the database camera by executing the file createDB.sql.

mysql -h localhost -u root --password=[mysql root password] < createDb.sql

Initialize the database

Decide whether you like to start with the surveillance entries of the first planet.osm file from September 12, 2012 or if you like to start with the latest planet.osm file or an extract of an individual country or region.

Start with the surveillance entries of the first planet.osm file from September 12, 2012

Pros: You don't have to download the latest +50GB planet.osm file to create a sql import file.

Cons: It could take several days until your database is up-to-date and contains all surveillance entries that have been added between September 12, 2012 and today. Furthermore you start with a data record for the whole planet. Maybe you are only interested in the data of a certain country or region.

Execute the file initializeDB_planet_20120912.sql for database user camera.

mysql camera -h localhost -u camera --password=[camera user password] < initializeDB_planet_20120912.sql

Start with the latest planet.osm file or an extract of an individual country or state

Pros: You start with the latest data records. Furthermore you can choose what country or region you like to map.

Cons: If you like to map the whole planet you have to download the latest +50GB planet.osm file. According to your internet connection this could take a while. At last you have to install the command line Openstreetmap data processor Osmosis on your computer.

Download the latest osm.bz2 file you like to extract the data from, e.g. from planet.openstreetmap.org or from download.geofabrik.de. They also offer a MD5 sum to verify the downloaded file.
Copy the just downloaded osm.bz2 file to the directory ~/sunders/init_cameras/.
Open the file ~/sunders/init_cameras/createInitialDataFiles.sh and enter the name of the osm.bz2 file as XML_FILE.

XML_FILE=[file name].osm.bz2
Execute createInitialDataFiles.sh to create the files surveillance.osm and initializeDB.sql.
Move the new files surveillance.osm and initializeDB.sql to the directory ~/sunders/init_cameras/db/ and change to that directory.
Execute the file initializeDB.sql for database user camera.

mysql camera -h localhost -u camera --password=[camera user password] < initializeDB.sql

Update the database

Change to the directory ~/sunders/update_cameras/.
Rename the file config.php.example to config.php.
Open the file config.php and enter the MYSQL_PASSWD of the database user camera. Furthermore enter the REPLICATE_URL that fits to your project, e.g. from planet.openstreetmap.org or from download.openstreetmap.fr. Here are some examples:

https://planet.openstreetmap.org/replication/minute/ http://download.openstreetmap.fr/replication/planet/minute/ http://download.openstreetmap.fr/replication/europe/minute/ http://download.openstreetmap.fr/replication/europe/netherlands/minute/
The update process is based on the sequence number comparison between the current state.txt file from the replication server, and the locally stored lastState.txt. So if you downloaded a osm.bz2 file, you should modify the sequenceNumber in the lastState.txt file accordingly.
Execute the file update_camera.sh to import all surveillance entries that have been added between the creation of the osm.bz2 file and today.

Schedule automatic database updates

Add this line to your crontab:

* * * * * /home/[user]/sunders/update_cameras/update_camera.sh > /dev/null 2>&1
Go to the directory ~/sunders/update_cameras/logs to check if your schedule works. After one minute there should be a new log file.
Go back to your crontab to change the schedule to the values you prefer, e.g. to 23 * * * * to run the update at every 23rd minute past every hour.

Configure the website

Change to the directory /var/www/sunders/.
Rename the file config.php.example to config.php.
Open the file config.php and change the definitions of DEFAULT_ZOOM, DEFAULT_LAT, and DEFAULT_LON to set the initial focus of the map to the location you want.

Surveillance nodes

Surveillance under Surveillance uses data from Openstreetmap contributors that is not visualized on the regular Openstreetmap site. If you like to add new cameras or guards or if you like to revise existing entries use your existing OSM account or create a new one.

These are the most common key/value combinations to describe a surveillance node at Openstreetmap:

Mandatory to display an icon on the map

Icon	Key	Value
`man_made`	`surveillance`
	`surveillance`	`public`
	`surveillance`	`outdoor`
	`surveillance`	`indoor`
	`surveillance:type` `camera:type`	`camera` `fixed` / `panning`
	`surveillance:type` `camera:type`	`camera` `dome`
	`surveillance:type`	`guard`
	`surveillance:type`	`ALPR`

Mandatory to draw camera's field of view

Key	Value
`camera:direction`	`0` - `360` (in degrees) or `N` / `NE` / `E` / `SE` / `S` / `SW` / `W` / `NW`
`camera:angle`	`15` - `90` (in degrees) from an almost horizontal view to a ground-pointed camera default: 15°
`height`	`3` - `12` (in meters) default: 5m

Example 1	Example 2	Example 3

direction = 90° angle = 15° height = 5m	direction = 90° angle = 15° height = 10m	direction = 90° angle = 60° height = 10m

Optional

Key	Value
`surveillance:zone`	`bank` / `building` / `parking` / `shop` / `town` / `traffic`
`camera:mount`	`ceilling` / `pole` / `wall`
`operator`	organization or person operating the camera
`name`	name of the camera
`ref`	reference number of the camera
`image`	link to an externally hosted image that depicts the surveillance object
