content: Hello. I am planning on making my home security system using a normal IP Camera, but I can't help noticing that some of them have a set of four pins that says alarm Input Output. Some of this cameras have motion detection, so I suppose that the camera can trigger an alarm when it detects motion. Does anybody knows exactly how the alarm I/O works? Here is a picture of an IP Camera with Alarm I/O.

content: Hi;Actually it depends on the firmware of the camera.I installed many cameras of that type, and usualy that I/O can have several funtctions, like the one that you are saying, also you can trigger an output by navigating the browser of the camera, and also you can have a I/O configurated as Input to receive an alert on the browser, or sending an email, or other thing.By the way, what is the model and brand of the camera?

content: Thank you! Actually, that picture is just an example from google. This is the one that I'd like to buy. Most of the cameras I've seen in this page (It's like eBay, but for Mexico) don't have a visible logo, but this one does.http://articulo.mercadolibre.com.mx/MLM-433946256-camara-ip-robotica-alta-definicion-zoom-digital-64x-con-dvr-_JMDo you know how does the camera communicates? Is it some kind of serial interface or something like that?

content: That's definitely a big ripoff. You can find IP cameras under $100.

content: Some of them are less than $1000 pesos (more or less $76 USD), but I'm not sure about the quality. Do you recommend any brand?

content: Quote from: ElectricGuy on December 19, 2013, 04:37:54 pmI found this on another forum (http://apexis-us.com/forum/apm-j011-external-i-o-alarm-settings-t771.html). It seems that the I/O Alarm does not need any kind of serial protocol or anything to work. It just triggers (or gets triggered) by writing HIGH or LOW on the pins. Is that right?

content: Yes, its right. You don't need any protocol. Usually you can activate the outputs by the browser, or by some kind of an event, like motion detection.
