GET
Required parameters:
command=arc.intervals – command to receive list of records
video_in – camera ID.
time_from – start of interested time range.
Optional parameters:
time_to – start and end of interested time range.
max_count – maximal number of records in reply
split_threshold – time for combining several intervals (in seconds). Intervals, distance between which will be less than specified value, will be combined in one.
format – if absent, the response is in XML; if set to json, the response is JSON.

Example JSON response:
{ 'count' : 1,'complete' : 'YES', 'sort' : 'INCREASE', 'cam' : '1', 'records' : [ {'from' : '2019-01-22T12:41:10.144+03:00', 'to' : '2019-01-23T08:28:47.346+03:00' }] } |

GET
Required parameters:
command=arc.frame - command for one frame;
video_in - camera ID;
time - interested time.
Optional parameters:
range - time in seconds to specify search range of the nearest frame relatively the time parameter (the nearest frame all over archive is searched if this parameter is not specified);
imageWidth - width in pixels (is counted automatically with saving proportions if it isn't specified or equal 0);
imageHeight - height in pixels (is counted automatically with saving proportions if it isn't specified or equal 0);
fps - maximal frame frequency per second (if it isn't specified or equal 0, frame frequency won't be limited if).
In return http-headings and the nearest frame from the [time - range, time + range] range in the jpeg format will be received. The reply body will be empty if there is no frame in the range.
Getting video from archive - "arc.play"
GET
Required parameters:
command=arc.play - command to get video from archive;
video_in - camera ID;

imageWidth - width in pixels (is counted automatically with saving proportions if it isn't specified or equal 0);
imageHeight - height in pixels (is counted automatically with saving proportions if it isn't specified or equal 0);
maximal frame frequency per second (if it isn't specified or equal 0, frame frequency won't be limited if).
End packet with newstate=closed and errcode=100 will be received when stream completion.

GET
http://example.com:[port]/web2/secure/archive/CAM:2/[2011-12-30|2011-12]?[splitThreshold=50]&[days=1]
splitThreshold – if difference between end of previous record and start of next record less than specified value (in milliseconds), than records will be combined in one. Specify splitTreshold=0. [default: 50] not to combine records.
days - number of days from the current, for which archive is required. [default: 1]
All time is interpreted as local time for server.
