The EOL resistor should connect into circuit in parallel connection.
Alarm input microseven nvr series#
The EOL resistor should connect into circuit in series connection. When alarm output (IP camera) is NC:You need to do the normal close connection.With correct connection, the IP camera can send signal to alarm system for associated alarm action.
The EOL resistor should be installed in the end of IP camera. The EOL resistor can protect the circuit of wiring to prevent short-circuit or cut. Please note that you need to use the EOL resistor in this connection. Connect the alarm output of IP cameras to hardwired zones of alarm panel. You can make connection between IP camera and hard-wired/wireless alarm panel. (This is NC connection, you need to choose the IP camera's alarm input property to NC.) Alarm Output (Connect IP camera to alarm system) In the above connection diagram, the DG85 (motion sensor)'s NC connects the positive (+) alarm input of IP camera, and the DG85 (motion sensor)'s COM (or GND) connects the negative (-) alarm input of IP camera. (Please note that you need to provide external power to the detectors) Hardwired sensor or device can parallel connect ground (-) end and COM end of the alarm detector, while parallel connect the NO (+) end and NC end of the alarm detector. The IP camera's alarm inputs are grouding alarm inputs (Normal open or Normal close type). Alarm Input (Connect sensor to IP camera) You need to use the suitable size wire for the connection, and it can be inserted into this block by pressing on the orange release button above the hole for the associated pin, then insert the wire, released the orange button to hold the wire. Typically you will see two different wiring blocks the block for screw fix installation, and the other block with orange release button. The alarm I/O pins is done via included green connector block (see below image).
Where I can find the alarm I/O? Making sure you get the camera with the alarm I/O, and the alarm I/O can be found on the back panel of IP camera. In conclusion, the alarm I/O can increase the flexibility for your IP camera installation and easily to integrate with other devices and sensors or even alarm panels for integration solution.
A high decibel siren also can connect to IP camera. For instance, you can connect the IP camera to several intrusion detection sensors for accurate intrusion detection. With this the IO interface, the IP camera can connect sensors to achieve integration solution. Similar to DVR/NVR, the advanced IP cameras are equipped with alarm input and output (I/O).
