Sending image from Hikvision camera with mail binding

Setup, Configuration and Use Items & Sitemaps
,
1

Hey all,

Specs: Openhab 1.8.1 on Ras pi.

I’ve been able to display the snapshot and video on my sitemap from my Hikvision DS-2CD2332-I What i want to do is add a button which takes a snapshot and sends it to my e-mail. I’ve actually got the button and the mail binding work, but i can’t get it to extract the photo.

I learned from a thread (that i can no longer find) that you cant use user:password in the mail binding, but apparently you can grab the snapshot and send it via e-mail some other way using the HTTP binding, but I can’t figure out how.

Sitemap:

      Frame label="Cameras" {
        Text label="Backyard" icon="camera" {
           Image label="Camera" url="http://admin:password@10.0.0.61/Streaming/channels/1/picture"
           Image label="Video" url="http://admin:password@10.0.0.61/Streaming/channels/1/preview"
		}

If someone can help me grab the snapshot from the camera and send it via e-mail i would greatly appreciate it.

Here is an screengrab of the camera. It is awesome and I highly recommend them:

got the same problem with Samsung camera in Sitemaps, I have the pictures, but that doesn’t work as an attachment in email
sendMail("kalender@gmail.com",“Post”,“Post ist da”,“http://user:pass@selfhost.eu:58081/cgi-bin/video.cgi?msubmenu=jpg”)
that does not so it isn’t
with telegram works but
sendTelegramPhoto(“Openhabbot”,“http://www.selfhost.eu:58081/cgi-bin/video.cgi?msubmenu=jpg”,null, “user”, “pass”)
is that a bug in email Binding?

If I remember it right, you have to grab the picture through exec binding (curl …), save the picture in your local file system (./webapps/static/*) and then send the mail with this local copy.

how times does that?how is the rules ?

5

Take a look at this thread: How to grab pictures from IP camera and send them to dropbox?

6

if I do so I get email while there but empty pic.jpg as an attachment here

val url = “http://user:pass@.selfhost.eu:58081/cgi-bin/video.cgi?msubmenu=jpg"
val outputFile = “/opt/openhab/webapps/static/pic” +”.jpg"
var cmd = “curl -m 10 -o " + outputFile + " " + url
executeCommandLine(cmd)
sendMail("openhab@gmail.com”, “Klingel”,"Klinge Door: ",“file://” + outputFile )
var Timer timer
timer = createTimer(now.plusSeconds(60)) [|
var cmddelete = “rm” + " " + outputFile
executeCommandLine(cmddelete) ]

7

Did you try the commands on a terminal in the openhab box, one by one, to check things work that way?

I must now test yet

that’s my openhab log

Hi,

is /opt/openhab/webapps/static/ present in your installation? the default path for apt-get installs is /usr/share/openhab

10

Yes that’s it

https://openhabdoc.readthedocs.io/de/latest/Raspberry/
so I installed

11

nobody has an idea?

12

I use it on my frontdoor bell button and hikvision cam.

Create a rule.

import org.openhab.core.library.types.*
import org.openhab.model.script.actions.*

rule “Frontdoor bell”

when
Item frontdoor_doorbell changed to ON
then
var FrontDoorCam = “FrontDoor”+ now.toString (“HH-mm_dd-MM-yyyy”) +".jpg"
var doorbellmessage = “Det ringet på døren kl. “+ now.toString (“HH:mm dd-MM-yyyy”) +”\nVi var sikkert ikke hjemme"
executeCommandLine(“wget http://admin:passwd@192.168.1.???/Streaming/Channels/1/picture -O /tmp/” +FrontDoorCam”,5)
Thread::sleep(5000)
sendMail("mail@gmail.com", “Det ringer på døren”, doorbellmessage, “file:///tmp/” +FrontDoorCam)
sendMail("mail@gmail.com", “Det ringer på døren”, doorbellmessage, “file:///tmp/” +FrontDoorCam)
end

13

no it don’t work any more, don’t know why

14

Cam",5")

How it works

15

Please use Code formatter to see the error easily:

executeCommandLine("wget http://admin:passwd@192.168.1.???/Streaming/Channels/1/picture -O /tmp/" +FrontDoorCam",5)

so, there is a " where it shouldn’t be. Complete working code:

import org.openhab.core.library.types.*
import org.openhab.model.script.actions.*

rule "Frontdoor bell"
when
    Item frontdoor_doorbell changed to ON
then
    var FrontDoorCam = "FrontDoor"+ now.toString ("HH-mm_dd-MM-yyyy") +".jpg"
    var doorbellmessage = "Det ringet på døren kl. "+ now.toString ("HH:mm dd-MM-yyyy") +"\nVi var sikkert ikke hjemme"
    executeCommandLine("wget http://admin:passwd@192.168.1.???/Streaming/Channels/1/picture -O /tmp/" +FrontDoorCam,5)
    Thread::sleep(5000)
    sendMail("mail@gmail.com", "Det ringer på døren", doorbellmessage, "file:///tmp/" +FrontDoorCam)
    sendMail("mail@gmail.com", "Det ringer på døren", doorbellmessage, "file:///tmp/" +FrontDoorCam) 
end

Why sending the email twice?

Hi everyone,

I have also adapted one of my rules to use this store-send-timer-delete approach.
Now an image file is created, but when the e-mail including the attachment should be sent, I also see this error in the log:

2016-07-22 16:35:11.793 [ERROR] [nhab.action.mail.internal.Mail] - Error adding attachment to email.
org.apache.commons.mail.EmailException: Invalid URL set:file:/space/smarthome/temp/16722_163511_7.jpg

I’m running OpenHAB 1.8.1 on a gentoo linux box, and I don’t understand why in the log there is only one slash (/) between file: and my file’s location, even though the attachment in the sendMail command is configured as

"file:///space/" + outputFile

Is there some restriction on where the file needs to be stored, or what is happening here?

17

OP here still trying to get things to work. My guess with @danielgauss148 is that it is using an escape character. Basically if you did only two // you would comment out the code but adding a third shows the system only two.

so in open hab i think ///=//

Anyway.

I’m closer, but mine still isn’t working.

Here is my rule:

rule "Frontdoor bell"
when
Item photoSwitch changed to ON
then

executeCommandLine("wget http://admin:password@10.0.0.61/Streaming/Channels/1/picture -O test.jpg")

end

this still won’t save anywhere on the pi that i can tell. If I put:

wget http://admin:password@10.0.0.61/Streaming/Channels/1/picture

into mobaxterm it will run and will download a photo, but i can’t seem to save anything when running it from openHab.

I came across this post when researching how to make this work with my Hikvision camera. I think I have a basic solution started that may work for you. I leveraged the avconv utility to grab an image from the rtsp stream.

First install the avconv utility:

sudo apt-get install lib-avtools

Next create a rule to grab a snapshot and e-mail a picture. I used a trigger of a motion detector detecting motion:

rule "SendCameraPic"
when
   Item FrontPorchMotion changed to OPEN
then {
   executeCommandLine("/usr/bin/avconv -loglevel fatal -rtsp_transport tcp -i ''rtsp://user:password@ip_address:554/PSIA/streaming/channels/101/'' -r 1 -vframes 1 /tmp/pic.jpg -y", 5000)
   sendMail('emailaddress', "Picture captured from camera", "The attached picture was captured when motion was detected", "file:///tmp/pic.jpg");
}

Watch within the executeCommandLine that the single quotes around the rstp string are escaped (two single quotes, not a double quote).

I just got this working now, so will need to test to see if it is stable. I hope it helps.

Hi again,

now I have tried lots of options with the attachment URL, but none of them worked.
A minor detail however, was the missing

Thread::sleep(5000)

in my rule. I figure that the script returns immediately after executing the commandline but the curl command itself is not finished.

Now with the sleep-command, sending attachments works fine.

Regards
Daniel

Now it works, I have a follow up question.
Do you really need the picture in the mail, or is a link to the picture on
dropbox also fine?

I’m asking because I don’t think e-mail is the place to store images…
