Dericam M801W IPcam

Bought recently a Dericam M801W IPcam but I cannot find documentation how to use the Alarm IO lines. Anyone experiences with similar interfaces on CAM's?

Mailed the helpdesk but no response yet ...

For the rest the cam works very well, both inside and outside.

Got a mail from the helpdesk today, so coming weekend I'm gonna test (or fry my cam :slight_smile:

Hi Rob,

Thanks for purchasing Dericam products.

The pin layout should be connected to the IO Alarm jack first.
From left to right, they are Output, Output, Alarm input and Input(GND).

Then connect Port 1 and Port 2 of the pin layout to the alarm such as buzzer.
Port 3 means the signal input of the alarm.
Port 4 means GND of the alarm.

Thanks & Best Regards

Experiment 1:

  • connected a LED + resistor to the pin2 + pin 4 [GND]
  • configured motion detect and a HIGH signal as output level

==> if motion detected I got an email with " motion alarm at 20120212194616" in the title, including some pictures.
==> pin 2 stayed HIGH for 60 seconds

Experiment 2:
Same but using pin1 as output did not work.
Measurements with a DMM indicates that pin1 is also [GND]

Experiment 3:

  • connected a LED + resistor to the pin2 + pin 4 [GND]
  • configured HIGH signal as output level; and trigger level HIGH
    ==> when pin3 was made HIGH I got an email with " extern alarm at 20120212194744" in the title, including some pictures.
    ==> pin 2 stayed HIGH for 60 seconds

Experiment 3:

  • connected a LED + resistor to the pin2 + pin 4 [GND]
  • configured HIGH signal as output level; and trigger level LOW
    ==> when pin3 was made LOW the system "overreacted" and switched continue on.
    Measuring pin 3 with a DMM gave a floating line between 2-4V ==> a pull up resistor is needed (not tried)

In short the system works good and it can be connected to an Arduino. Voltage level is a bit high 5.2 Volt but within spec of the Arduino.

The final pinlayout is :

PIN 1: GND
PIN 2: OUTPUT
PIN 3: INPUT
PIN 4: GND
