1.4.3. Hardware Setup - Sensor Settings

1.4.3.1. Overview
In the Sensor Settings the user can configure the connected sensors. Sensors must be set as NC or NO (NC = Normally
Closed; NO = Normally Open) as per sensor device specifications.
Electrically, sensor (input) devices are classified as normally open and normally closed. The term "normally" refers to the
state of the device in its resting position — without any external forces acting on it.
A NC sensor is any sensor with an electrical circuit closed by default. A normally closed sensor is one that normally allows
electrical current to flow and which prevents the current flow when it is perturbed. In other words, NC contact will carry
electricity until it is activated.
A NO sensor is any sensor with an electrical circuit open by default. A normally open sensor is one that normally prevents
current flow and which allows current to flow when it is perturbed. In other words, NO contact will not carry electricity
until it is activated.
1.4.3.2. Creating/Modifying Sensor Settings
To configure the available sensors, do the following:
1. Check the All checkbox to enable all sensors or enable desired sensors by checking individual sensor checkboxes
2. Assign a descriptive Name to each sensor. For example, the sensor could be named based on the sensor function or
trigger (e.g. "Fire on 1st floor").
3. Click the NC/NO to set the sensors to NC (Normal Closed) or NO (Normal Open) depending on the type of the sensor.
Follow the manufacturer's specification.
4.
Assign a Linked Channel to the desired sensors. Click the Browse button
the list. If the specific sensor is triggered, the selected channel will begin recording. In the above example, if Sensor
1 is triggered, Channel 1 (Front Door) will start recording.
By linking video channel to a sensor, the emergency frame rate recording can configured for the linked camera. See
Recording/Display section for more information.
5.
Assign a Linked Control to the desired sensors. Click the Browse button
the list. If a specific sensor is triggered outside of the Control Active Time, the selected control is activated. In the
above example, if Sensor 1 (Motion Sensor) is triggered, Control 1 (Front Door Lock) will be activated.
6. Choose Enable to have the alarm sound every time the sensor is triggered
OR
Choose Disable to disable the alarm
