IO Alarm
<p>[TOC]</p>
<h3>I. Summary Description</h3>
<p>IO alarm function, which is an alarm triggered by the high or low input voltage of the device IO line.</p>
<ul>
<li>Support for multiple enablement options.</li>
<li>Support for the selection of high and low levels.</li>
<li>support the time setting of delayed alarm (delayed alarm after triggering the alarm)</li>
<li>support the time setting of anti-shake (the time of continuous alarm conditions and alarm only when the anti-shake time is reached).</li>
<li>support for alarm linkage of multiple functions.</li>
</ul>
<h3>II. Conditions of use</h3>
<ol>
<li>The device has IO line with IO alarm function.</li>
<li>the IO voltage input is normal.</li>
</ol>

<h3>IV. Detailed operation</h3>
<h4>1、Check if the device IO line voltage input is normal</h4>
<p>In the <strong>Device State-Sensor</strong> interface, you can view the IO status; <strong>0-is in a low state, 1-is in a high state. </strong>
Under normal conditions, try to change the high and low level inputs of the corresponding IO lines to see if the IO status has changed correctly; i.e.
The IO line whose status shows low level is connected to high level to check whether the IO status changes from 0 to 1; the IO line whose status shows high level is connected to low level to check whether the IO status changes from 1 to 0.</p>

<h4>2、Turn on IO alarm function</h4>
<p>Turn on alarm enable in <strong>Alarm Setup-IO</strong>.</p>
<ul>
<li>Support for the selection of multiple enables.</li>
<li>support for high and low selection of the selection level.</li>
<li>support the time setting of delayed alarm (delayed alarm after triggering the alarm).</li>
<li>support the time setting of anti-shake (time of continuous alarm condition, alarm only when anti-shake time is reached).</li>
</ul>

<p>Alarm linkage function</p>
<ul>
<li>Support alarm recording function, please refer to the section on [alarm record](<a href="http://118.195.179.210:9000/web/#/11/257">http://118.195.179.210:9000/web/#/11/257</a> "alarm record") for details.</li>
<li>Support for opening the buzzer (the device needs to be equipped with a buzzer).</li>
<li>Support for linkage output voltage (device needs to come with IO output line).</li>
<li>Support alarm picture capture function (pictures are stored in the device disk by default, please refer to the section on [capture functionin](<a href="http://118.195.179.210:9000/web/#/11/278">http://118.195.179.210:9000/web/#/11/278</a> "capture functionin") the device linkage capture - upload to the platform description).</li>
<li>support preview channel (after checking the channel, trigger the alarm, local preview of the checked channel, do not check the default preview of all channels).</li>
</ul>

<h4>3、Display</h4>
<h5>3.1 Device：</h5>
<ul>
<li>can show the preview channel by ticking it, and after the alarm is triggered, the local preview will only show the ticked channel and return to normal after the alarm is over.</li>
<li>can search in <strong>Search-Log</strong> after selecting the log category as <strong>Alarm Log</strong> to see if there is an alarm log.</li>
</ul>
