**** How use discovery module in your PHP code:

1. Required module (for WS and UPNP)

   require "lib/class.ponvif_ext.php";

2. WS Discovery:

   try { $test=new ponvif_ext(); $results=$test->wsdiscovery(); .... } catch (Exception $e) { .... }

2.1) Collateral functions:

2.1.a) setWSDiscoveryScriptPath($scriptPath): use this if you need to change the pointing to the Python script ponvif-wsd-ext.py

2.1.b) setWSDTimeout($timeout): use this to change the default timeout (how long the WS Discovery module have to wait before end); value in seconds; default is 5

2.1.c) getWSDTimeout(): get current WS Discovery timeout

3. UPNP Discovery:

   try { $test=new ponvif_ext(); ... $checkIfOnvif=true; // if true, tries to check if camera is ONVIF compliant (default is false) ... $filters=array(); // if empty, finds all UPNP devices (default is empty) ... $filters=array('ModelName'=>'camera','ModelDescription'=>'camera'); // if defined, tries to find a specific type of devices (in this case cameras) ... $results=$test->upnpdiscovery($checkIfOnvif, $filters); .... } catch (Exception $e) { .... }

3.1) Collateral functions:

3.1.a) setUPNPDiscoveryScriptPath($scriptPath): use this if you need to change the pointing to the Python script ponvif-upnp-ext.py

3.1.b) setUPNPTimeout($timeout): use this to change the default timeout (how long the UPNP discovery module have to wait before end); value in seconds; default is 5

3.1.c) getUPNPTimeout(): get current UPNP discovery timeout

3.1.d) setUPNPInspectTimeout($timeout): use this to change the default timeout (connection timeout used during details acquisition and onvif compatibility checking); value in seconds; default is 10

3.1.e) getUPNPInspectTimeout(): get current UPNP discovery inspection timeout

3.1.f) setUPNPIface($iface): change the local IPv4 or IPv6 address to which to bind

3.1.g) getUPNPIface(): get current interface setting
