HTTP event from camera - 2MAX - 06.02.2023

Hi, i connect camera HTTP event to LM and i need to write group adress on the bus if event {alarm} is true.

this is log from LM
* table:
["alarm_2"]
* bool: true

this is .lp script
<?

require('apps')
vars = getvars()
log(vars)

RE: HTTP event from camera - admin - 06.02.2023

Try this:

Code:
<?

require('apps')

vars = getvars()

if vars.alarm_2 then

  grp.write('1/1/1', true)

end

Thanks, what if alarm_2 wil be false?

RE: HTTP event from camera - admin - 06.02.2023

Nothing will happen. It cannot be really false. It can be either nil, true or a string. You can add an else clause to write a different value to the object if needed.

Ok, this is works fine. I want to use scritp with 16 cam, each camera has diferent event name ( alarm_1, alarm_2, alarm_3,.....a, alarm_16) for log from witch is alarm send.
how to change script to works with this changing event name?

RE: HTTP event from camera - admin - 06.02.2023

You can do it like this, alarm_1 will write to 1/1/1, alarm_2 to 1/1/2 and so on.

Code:
<?

require('apps')

vars = getvars()

for i = 1, 16 do

  if vars['alarm_' .. i] then

    grp.write('1/1/' .. i, true)

  end

end

But you cannot use else clause here because it will reset all other alarms. Either the alarm variable should have some value (like 1/0) or you should check the IP address of the camera that sent this event.

ok, i thank for your help, only one adress i need to write, but log each of event, something like this:

Code:
<?

require('apps')

vars = getvars()

for i = 1, 16 do

  if vars['alarm_' .. i] then

    grp.write('33/2/1', true)

  end

end

log(vars)

it looks to work from each cam
