Monitor live feed and capture JPG

[scrapdealer 0]

Looking for some direction as I've no experience with CCTV systems.

 

I need to position a camera outdoors over a truck scale to view the vehicle as it stops on the scale and capture a jpg image of whatever is sitting on the scale. Capturing the image would be initiated by the scale operator running software on a PC. Ideally I would like to embed this monitoring and capture function in our software that's run using a web browser (html, javascript, php). We have to capture jpgs and associate them immediately with a transaction on our system. PC is currently running Windows XP.

 

Any suggestions or direction is greatly appreciated.

Have done this years ago with multiplexer and VCR

at that time I contact with scale tech and got trigger output from scale

to start recording

as of today easy to do with any analog or IP system

Yeah, there are several different ways to do this. Any number of IP cameras have the ability to send a JPG to an ftp folder, an email address, and/or a network drive when an external input is received, whether a trigger from an operator, or an in-ground loop, or an electric-eye beam, or whatever else you may want to rig up to signal it. Several of those can also record internally, so there's no additional computer needed.

Thanks for the quick feedback. Any suggestions on cameras and/or information on types of cameras, what features I would need, etc. Again, I'm not a cctv guy, just a business applications programmer looking to learn.

The Dahua 3MP box cam I'm using right now will do all this: it has an SD card slot (up to 32GB SDHC) to record internally, or you could put any number of different NVR apps on your PC, or even use its included PSS software to record... and it can send a snapshot to an FTP server on whatever trigger event you want to define (including motion detect, so you could even just define a small motion zone and have it take the snapshot when the truck enters that area).

Can't seem to find much info on the Dahua 3MP. Does anyone know if this is a current model or has it been replaced? I don't need to record video, just monitor and take a "snapshot", store it in a specified location on the network. POE would be nice.

It's a current model; It does fit all the other requirements.

 

Box cameras rarely do include lenses, because there are so many lens options out there. The one you use will depend on the specific view required. The one that you can order with it should be suitable for your needs.

The product descriptions state that an activity (capture snapshot or recording) can be triggered by an alarm. Examples of these alarms are always physical devices, i.e, motion detectors. Can the alarm be programmatically triggered by a button on a web page? If so, does anyone have an example of how this is done.

 

thx.

There's a button on the camera's own web interface that will do it... if you're a savvy web programmer and you're programming the camera's feed to show in your own interface, I imagine it should be easy to add the snapshot button as well (don't ask me how; I'm not a coder).

We ordered an Dahua ESIP-MP2-DM1 to tinker with. There is in fact a snapshot button on the web console for the camera, but it uses an activex control. We are trying to find a way to use an http request as an alarm rather than resorting to activex (and thus constricting ourselves to Internet Explorer). Has anyone ever done something like this specifically using an http request (i.e. calling http:///cgi-bin/getImage)?

Really all I need is an outdoor still image camera, ip capable, poe preferred, that will allow me to display the "viewfinder" in my html page, trigger the "shutter" by clicking a button on the web page and store the image on a network drive. Don't need to record video.

Any ideas?
