FAQ
How to
The SIM card
To open the case (indoor version), place your thumbs against the corners of the top, above the white line. Use your middle fingers to apply counter-pressure to the back, below the white line. Gently push the top backwards with your thumbs. Once it has shifted by about 1 cm, lift the top off.

How to place the SIM card?
See the picture and video to open the SIM card holder cover and insert the SIM card.

Slide the metal part slightly to the left and gently lift the flap upwards.
Insert the SIM card with the copper side facing downwards, with the slanted corner as shown in the picture.
Lower the flap again and slide the metal part slightly to the right.
LED behaviour (devices with SN Rxx)
- LED flashes green, 1 second on/1 second off
The device is not yet programmed. Activate the device in the Mobeye Portal or (if “stand-alone”) program at least one phone number (TEL1). - LED flashes green briefly every 3 seconds
The device is on and runs on batteries. - LED is continuously green
The device is on and operates on external power. - LED flashes very fast
The devices communicates with the Mobeye Portal. - LED flashes red/green
The communication module is searching for a network connection. Wait until the connection is established. If this takes longer than 3 minutes, follow the steps under “2x red” or “3x red”. - LED flashes 3x green
The devices has has received a correct SMS command. - LED flashes 5x red
The devices has received an incorrect SMS command. - LED flashes red twice every 3 seconds
There is no GSM connection. Check the operation of the SIM card in a mobile phone.

Own SIM? Replace the SIM card with a card from another provider; place the module in a different location. - LED flashes red 3 times every 3 seconds
There is a SIM card error or there is no credit.
Mobeye SIM? Consult Mobeye.
Own SIM? Check the operation of the SIM card in a mobile phone; remove the PIN code; check credit; replace the SIM card. Perform a complete reset. - LED flashes red 4 times every 3 seconds
The communication module cannot read the SIM card, or the PIN code is blocked.
Mobeye SIM? Consult Mobeye.
Own SIM? Check the operation of the SIM card in a mobile phone; remove the PIN code; replace the SIM card. Perform a complete reset. - LED flashes red 4 times every 3 seconds (on startup), with a brief green in between.
Low battery voltage, replace the batteries. - LED is off
The device is turned off, or the batteries are dead and there is no external power supply.
Battery replacement
If a device operates entirely on battery power, without external power, the batteries should last at least a year. This applies even with a daily (test) notification. If mobile network coverage is weak locally, this may be shorter. Just like any mobile phone, the internal communication module will increase power to find a signal. This affects battery usage.
If a device is externally powered and the batteries are only used sporadically as a backup during power outages, they will last much longer, longer than 3 years.
A notification follows when the battery voltage is low. For devices connected to the Mobeye Portal, this is in the form of a “service notification”. If this is missed, the absence of a test notification (“keep alive”) is a second indicator. A device operating standalone (without the portal) sends the low battery notification to the first phone number (TEL1).
Connecting multiple sensors to an input
Multiple sensors can be connected to one NO/NC alarm input. Place a normally closed input contact in series, a normally open contact in parallel. In this way, an activated sensor will trigger an input alarm. Since there is one text per input, it does not provide specific information about the activated sensor.
How long can the wire of a sensor be?
The maximum allowed length of the wire of a sensor depends on the type of signal, the wire thickness and the quality of the wire:
How to prevent alternating input behaviour or false alarm?
If the alarm system incorrectly detects alarm and alarm reset in quick succession, it is advisable to program an input delay. If the sensor output contact gives multiple signals in the alarm status, it is advisable to program an inactive time on the input.
How to calibrate analog inputs?
The analog inputs of the Mobeye devices are pre-calibrated. For the CM4600 and CML4055, this has been done at 0V and 48V. For an even more accurate measurement, calibrate the input to the alarm value using a (calibrated) voltage generator. Ensure that the device is in programming mode and that the input type is set to AN. Apply a continuous voltage to the input. Send the following SMS to the device:
For input 1, if the calibration value is 12V, code 1111:
1111 CALIBRATE1:12
Immediately afterwards, query the status to check the value: 1111 STATUS?
For input 2, if the calibration value is 12V, code 1111:
1111 CALIBRATE1:12
