NAME

IPCamera::Reolink - Reolink API provides access to the System, Security, Network, Video input, Enc, Record, PTZ, and Alarm functions of a Reolink IP Camera or NVR via HTTP(S)/REST

VERSION

1.00

SYNOPSIS

use IPCamera::Reolink;

my $camera_url = "http://192.168.1.160";
my $camera_user_name =  "vlc"; # non-admin user recommended
my $camera_password = 'this-is-a-bad-password';

my $camera = IPCamera::Reolink->new($camera_url, $camera_user_name, $camera_password);

# Optionally Login to the camera immmediately to validate the camera URL and credentials, otherwise a Login will be implicitly performed by the API on the first camera command.

die "IPCamera::Reolink::Login failed" if(!$camera->Login());

# Some camera info

my $devinfo_r = $camera->GetDevInfo();
print "Camera model : " . $devinfo_r->{model} . "\n";
print "Camera name : " . $devinfo_r->{name} . "\n";

# Start a camera pan to the left.

$camera->PtzCtrl(IPCamera::Reolink::ChannelDefault, IPCamera::Reolink::PTZ_Left, IPCamera::Reolink::PTZ_SpeedMax);

# Times passes, stop the last camera PTZ function.

$camera->PtzCtrl(IPCamera::Reolink::ChannelDefault, IPCamera::Reolink::PTZ_Stop, IPCamera::Reolink::PTZ_SpeedMin);

$camera->Logout();

DESCRIPTION

IPCamera::Reolink provides a simple way to interact with Reolink IP cameras and NVRs.

Based on the "Reolink Camera API User Guide_V8 (Updated in April 2023)" document, available here:

https://github.com/mnpg/Reolink_api_documentations

As the author is primarily interested in accessing the Pan/Tilt/Zoom (PTZ) functions of his Reolink RLC-823A-16x IP camera, only the subset of functions described in the above document needed to access these features have been implemented.

Other functions may be added in the future based on the need/whims of the author and requests from other (if any) users of this module.

ATTRIBUTES

DEBUG

Set $IPCamera::Reolink::DEBUG to a value > 0 for increasingly detailed debug output to STDERR.

default is 0 for no debug output.

VERSION

$IPCamera::Reolink::VERSION is the version of this module.

METHODS

new($camera_url, $camera_user_name, $camera_password)

Construct a new IPCamera::Reolink object.

Takes the following manditory parameters:

$camera_host_url

The camera URL for access via HTTP(S), i.e. "http://192.168.1.123".

$camera_user_name

The camera account name for access via HTTP(S), i.e. "vlc".

You should set up a non admin acccount for access via this API, the admin account will work as well but is not recommended.

But just to complicate things, certain methods (described below) require admin access to use with the current version of the camera firmware.

Reolink may fix this in the future.

$camera_password

The camera account password for access via HTTP(S), i.e. "this-is-a-bad-password".

Upon successful Login the camera passes back a Login token and lease time that is used internally by other IPCamera::Reolink camera API methods.

The token is valid for the specified lease time.

IPCamera::Reolink will manage the Login token and will call Login() internally as needed when the Login token expires.

This should all be invisible to the caller.

return

Returns (undef, udef) if the Login was rejected by the camera.

Returns ($camera_login_token, $camera_login_lease_time) if the Login is successful, where $camera_login_token is the token passed to other API methods and $camera_login_lease_time is the time in seconds for which the token is valid, after which a new token must be aquired.

Usually the caller is not interested in these values as they are used internally by IPCamera::Reolink.

Logout()

Release Login() credentials.

return: Returns 1 if Logout() succeeded else 0 (zero) on failure, typically if Login() not called.

GetDevInfo()

Return useful information about the camera.

return

Returns undef if the GetDevInfo function failed.

Returns $devinfo_r hash reference to device information if successful, fields most likely subject to change (typical values in parenthesis):

$devinfo_r->{audioNum} (1): The number of audio channels.
$devinfo_r->{B485} (0): 0: no 485, 1: have 485
$devinfo_r->{buildDay} ("build 23061923"): The establish date.

$devinfo_r->{type} ("IPC"): Device type.
$devinfo_r->{wifi} (0): 0: no WIFI, 1: have WIFI.

PtzCtrl($camera_channel, $camera_operation, $camera_operation_speed)

Control camera PTZ functions.

Upon successful return the camera asynchronously executes the requested operation until another operation is specified by PtzCtrl() or until the camera limit is reached for the specified operation, for example the camera has tilted as far Down as physically possible.

Some operations like IPCamera::Reolink::PTZ_Left will execute forever until another PtzCtrl command is executed.

$camera_channel

Perform camera operation on specified camera channel:

IPCamera::Reolink::ChannelDefault: If you are connected to a camera then there is (usually) only 1 channel.
integer >= 0: If you are connected to an NVR then there is usually one channel per attached camera starting at integer value 0.

$camera_operation

Camera operation to perform:

IPCamera::Reolink::PTZ_Stop: PTZ stop turning.
IPCamera::Reolink::PTZ_Left: PTZ turn left at the specified speed.
IPCamera::Reolink::PTZ_Right: PTZ turn right at the specified speed.
IPCamera::Reolink::PTZ_Up: PTZ turn up in the specified speed.
IPCamera::Reolink::PTZ_Down: PTZ turn down at the specified speed.
IPCamera::Reolink::PTZ_LeftUp: PTZ turn left-up at the specified speed.
IPCamera::Reolink::PTZ_LeftDown: PTZ turn left-down at the specified speed.
IPCamera::Reolink::PTZ_RightUp: PTZ turn right-up at the specified speed.
IPCamera::Reolink::PTZ_RightDown: PTZ turn right-down at the specified speed.
IPCamera::Reolink::PTZ_IrisDec: Iris shrink at the specified speed.
IPCamera::Reolink::PTZ_IrisInc: Iris enlarge at the specified speed.
IPCamera::Reolink::PTZ_ZoomDec: Zoom in at the specified speed.
IPCamera::Reolink::PTZ_ZoomInc: Zoom out at the specified speed.
IPCamera::Reolink::PTZ_FocusDec: Focus backwards at the specified speed.
IPCamera::Reolink::PTZ_FocusInc: Focus forwards at the specified speed.
IPCamera::Reolink::PTZ_Auto: PTZ turn auto at the specified speed.
IPCamera::Reolink::PTZ_StartPatrol: PTZ patrol at the specified speed.
IPCamera::Reolink::PTZ_StopPatrol: PTZ stop patrol.
IPCamera::Reolink::PTZ_ToPos: PTZ turn to at specified preset at the specified speed.

$camera_operation_speed

Perform camera operation at the specified speed:

IPCamera::Reolink::PTZ_SpeedMin: Minimum camera operation speed.
PTZ_SpeedMin::PTZ_SpeedMax: Maximum camera operation speed.
PTZ_SpeedMin::PTZ_SpeedHalf: 1/2 Maximum camera operation speed.

GetZoomFocus($camera_channel)

Return camera current Zoom and Focus values.

$camera_channel

Perform camera operation on specified camera channel:

IPCamera::Reolink::ChannelDefault: If you are connected to a camera then there is (usually) only 1 channel.
integer >= 0: If you are connected to an NVR then there is usually one channel per attached camera starting at integer value 0.

return

Returns undef if the GetZoomFocus function failed.

Returns $zoom_focus_r hash reference to Zoom/Focus information if successful, fields most likely subject to change (typical values in parenthesis):

$zoom_focus_r->{channel} (0): Camera channel.
$zoom_focus_r->{focus}->{pos} (23): Current camera focus value in the range IPCamera::Reolink::ZF_FocusPosMin, IPCamera::Reolink::ZF_FocusPosMax.
$zoom_focus_r->{zoom}->{pos} (0): Current camera zoom value in the range IPCamera::Reolink::ZF_ZoomPosMin, IPCamera::Reolink::ZF_ZoomPosMax.

StartZoomFocus($camera_channel, $camera_operation, $camera_zoom_pos|$camera_focus_pos)

Set camera current Zoom or Focus value.

Note that the current version of the firmware on the authors camera (Firmware Version v3.1.0.2347_23061923_v1.0.0.93) requires a Login() using admin credentials to use this function. According to Reolink this may be fixed in a future firmware version.

If in doubt, set $DEBUG to 1 and if you see a log message of the form:

Tue Dec 19 18:17:07 2023: debug: IPCamera::Reolink::_sendCameraCommand(): command 'StartZoomFocus' token '5b34aab0bb481ba' request '[{ action => 0, cmd => "StartZoomFocus", param => { ZoomFocus => { channel => 0, op => "ZoomPos", pos => 1 } } }]' response '[{ cmd => "StartZoomFocus", code => 1, error => { detail => "ability error", rspCode => -26 } }]' time 0.0480499267578125 seconds

then you need to use admin credentials to use this function.
