Mobeye <\/strong>Technical Terminology<\/h2>\n\n
\n

Our aim is to provide technology as a tool in situations where surveillance is required. We also hope that our products are used with pleasure and that users feel comfortable with them. That is why Mobeye products are easy to use and the documentation is accessible. However, it is inevitable that we too use terms on our website, in our datasheets and in our manuals that may not be immediately clear to everyone. For your information and enjoyment, we explain a number of \u2018technical terms\u2019 in the context of Mobeye products. <\/p>\n\n\n\n

GSM \/ 2G \/ UMTS \/ 3G \/ 4G \/ NBIOT \/ LTE-M \/ CAT-1 \/ CAT-12 \/ 5G<\/h3>\n\n\n\n

There are various technologies used for mobile communication. With the first mobile phones, the landscape was straightforward; GSM, also known as 2G, was the dominant technology. This network is still in use today. Then came UMTS, or 3G. This technology did not have a long lifespan. After that came 4G, with various bandwidths. Countries and providers choose their own timetable for rolling out the various \u2018layers\u2019 of 4G. In some countries, the introduction of 5G is already in full swing.The latest Mobeye products feature a 4G CAT-1 communication module with fallback to 2G. This is one of the lowest frequency bands within LTE. LTE is a sort of synonym for 4G and stands for Long Term Evolution. The CAT-1 band has been developed for machine-to-machine applications with relatively low data usage. Its coverage <\/a>is much better than 2G and 4G \u2018streaming bands\u2019, and it penetrates deep into buildings. Furthermore, it is much more energy-efficient, making it ideal for battery-powered applications. If 4G is unavailable, Mobeye devices connect to 2G; this means they can be used throughout Europe and in most countries worldwide. <\/p>\n\n\n\n

For specific applications, Mobeye offers versions with an LTE-M band and a global WW band (including the US and Canada).<\/p>\n\n\n\n

Passive infrared (PIR)<\/h3>\n\n\n\n

A PIR sensor, such as that used in the Mobeye MiniPir and Outdoor Detector, detects moving heat sources. The (Fresnel) lens consists of several parts. As soon as the thermal image (infrared radiation) changes, the detector reacts. People, large animals (not insects or spiders), draughts and direct sunlight on the lens are detected. Therefore, avoid draughts and direct sunlight. If a false alarm has occurred, reposition the alarm system or set the sensor sensitivity to \u2018low\u2019. <\/p>\n\n\n\n

What is jamming?<\/h3>\n\n\n\n

Jamming <\/em>involves suppressing wireless signals by transmitting a disruptive signal on the same frequency. Mobile phone jammers are used only by a small group of highly professional burglars, but they do interfere with the transmission of alerts if held near the device. Mobeye products are designed to detect this. If a burglar jams an alarm system, the Mobeye alarm system will detect this. As soon as the source of interference is removed, the alarm system will still transmit the alarm as quickly as possible, with a notification that it has been delayed. <\/p>\n\n\n\n

The difference between NO \/ NC and analog inputs<\/h3>\n\n\n\n

When discussing the inputs on Mobeye devices, the type of input is important. After all, this determines the type of sensor \u2013 or, more precisely, the sensor\u2019s output signal \u2013 that can be connected. Here, we will attempt to explain the difference between inputs for potential-free, digital and analogue contacts in simple terms. We will focus here on the output signal of the sensor connected to the Mobeye input. <\/p>\n\n\n\n

NO\/NC alarm inputs<\/h4>\n\n\n\n

A potential-free (voltage-free) contact can be connected to \u201cnormally open\u201d and \u201cnormally closed\u201d inputs. Put simply, the contact switches the input to \u201copen\u201d or \u201cclosed\u201d. It is therefore important to know whether the connected sensor has a voltage-free output. A reed switch is a purely voltage-free switch; a signal derived from a fault indicator light will, however, transmit a voltage. The Mobeye NO\/NC inputs can still recognise a limited voltage as voltage-free; see the FAQs<\/a> for more information. <\/p>\n\n\n\n

Analog inputs<\/h4>\n\n\n\n

An analogue input expects a (limited) input voltage, which the Mobeye circuit board reads. The voltage value provides information about the sensor being read. For example, the battery voltage gives a direct indication of its status. For other analogue sensors, the Mobeye device will convert the voltage into other values, such as pressure, humidity or ammonia levels. <\/p>\n\n\n\n

Digital (uniwire) inputs<\/h4>\n\n\n\n

A digital (Uniwire) input receives signals in the form of zeros and ones. The sensor transmitting these signals has internally converted a measured value into a digital signal. There is little interference during the transmission of the digital signal. Upon reception, the signal is converted back into a logical value. The digital Mobeye inputs also apply the voltage required to read the sensor. <\/p>\n\n\n\n

The difference between an open collector and a relay output<\/h3>\n\n\n\n

Some Mobeye devices have an output that can be used to control something. This output is also known as an actuator. Some devices have an open-collector output, whilst others have a relay. <\/p>\n\n\n\n

Relay output<\/h4>\n\n\n\n

A relay is a type of switch. It is mounted on the circuit board but forms its own (galvanically isolated) circuit. Internally, it contains a coil, an electromagnet and a circuit. The circuit has two states: \u201copen\u201d and \u201cclosed\u201d. The Mobeye device can apply voltage to the relay, for example following an alarm or an incoming command. The coil then generates a magnetic field, which causes the circuit to change state. An external device connected to the relay utilises this \u201copen\u201d or \u201cclosed\u201d status. This allows it to be activated or deactivated. No voltage is output from the relay (\u201cpotential-free circuit\u201d). <\/p>\n\n\n\n

Open collector output<\/h4>\n\n\n\n

An open-collector output is a type of switch. It is mounted on the circuit board and provides an output voltage. By varying the resistance value, the status of this output can be controlled. The status is either \u2018grounded\u2019 or \u2018floating\u2019 (open circuit, disconnected). At high resistance, no current flows through the circuit. The Mobeye software can set the resistance to zero, for example following an alarm or an incoming command. This causes the output to switch open. There is always an output. There is always an output voltage at the output that is equal to the external power supply on the Mobeye device (e.g. 12V). An external device connected to the open-collector output can use this 12V voltage as its input voltage (max. 200 mA). For a more power-hungry device, an external relay is required. The open-collector output is then used to drive the relay. <\/p>\n\n\n\n
