Instant Price Quote for ComSec-2000_4G
Main Features:
Available Communication Channels:
- CAT-M1 (on 4G infrastructure)
- NB-IoT (on 4G infrastructure)
- GPRS 2/2.5G (fall-back option)
- IP (10/100 Mbs Ethernet)
- WiFi (4 different channels)
- PSTN Dialer (Contact-ID format)
Dual-SIM models feature two SIM cards, enabling the unit to connect to a second GSM carrier in case the Primary carrier communication path fails.
All models feature 8 dry-contact Inputs + Tamper input, each programmable for its Event Code, Polarity, Sensitivity. Optionally, the first 6 inputs can be programmed for End-of-Line Resistor protection.
Monitoring of Power Supply Input (Mains AC power monitoring) and Battery Voltage (including Battery test under Load). Reporting on AC status, Battery Low & Battery Missing.
Extended operation voltage range: 8-28 VDC (compatible with 24V Fire Alarm Panels).
Simple Alarm Panel functionality - the inputs can be programmed for Alarm Zones property, e.g. Immediate, Delayed, Follower, 24-Hour, Silent type. One input can be designated as an Arm/Disarm Key Switch input. Outputs are used for Siren and Alarm System Status monitoring. The unit can be optionally remotely Armed/Disarmed from the Central Server.
Universal Alarm Panel Interface (in "P": models), connects to all types of Alarm Panels on their Tel. Line Input and retransmits all the Events via the GPRS channel (Contact-ID format only).
Option: 4 Outputs for internal state monitoring and Remote Control:
- 1 Change-Over dry contact Relay
- 3 open-collector, 1 Amp. Max.
5-Level GSM Signal Strength indicator (RSSI).
Connected Network type indicator LEDs – GSM/IP-WiFi/Connection via SIM1 (GSM Provider 1) / SIM2 (Provider 2).
NEW: Programming the unit from any standard Internet Browser, from any PC or Smart-Phone that connects to the Internet: by default, the ComSec-2000 connects to a special Server with Web interface service. It can then be identified by its unique SIM card serial number (IMEI) or the MAC address on IP channel, and then re-programmed from any device with WEB access, such as a hand-held Cellular Smart-Phone. In addition to programming, the technician can then check the proper function of the unit, including the RF reception level at the site (RSSI).

We have a new improved model of the Amit-2000 Receiver (Amit-2020).

Also we have a 4G based NB-Iot & CAT-M1 version of our Comsec-2000 line.

It seems we are among the very few who have this new IoT communication capability.

You can find the updates in the web-site.
Also updated the WinGal software to the new WinGal2000 in the web-site.

Local municipalities use d.e.s.k.. electronic systems products for a remote alarm centre to monitor security alerts at various schools, stores and other municipality owned buildings. The Wingal software as an automation system to receive alerts via telephone, radio and cellular communications, access the relevant instructions on the site, including building drawings, photos and emergency protocols. In addition, a video module was developed to access remote CCTV DVR and IP cameras, record the video at the alarm centre , and indicate to the control room person that there is a video is available for this alert.The operator is then able to open the video that was recorded when the alert was sent, as well as a live realtime video from the site at that moment.

ATM Manufacturer
d.e.s.k. Electronic systems supplied an alarm system to a well known ATM manufacturer based on the GPRS RTD-804 communicator. The unit, which has 8 inputs is used as an alarm system, where one input is used as a key to arm and disarm the unit, and the other 7 inputs are used to connect to a sensor such as a motion detector. The customer saved on the cost of a dedicated alarm panel
