Can thieves hack into our facility’s security system covertly and disable it or somehow modify it so that it malfunctions during a robbery?
Everything is theoretically possible, but in reality it is extremely unlikely. I’ll start off by saying that in this discussion, professional security systems with round-the-clock security are taken into consideration; autonomous / GSM alarms from China and other “craftsmanship” alternatives are not.
As a result, a unique sort of alarm called “tamper opening” is included in practically all console security systems. The operator of the monitoring station will know without a doubt that the instrument case has been opened at the facility if such a message reaches the station. Additionally, this is constantly observed, similar to how fire alarms are monitored (smoke, gas detectors, etc.).
Regarding the alleged “tamper,” it is possible with regular sensors as well as receiving control devices (PPK). The basic idea is typically the same as that of the device: when the lid is opened, the contact is initiated by adjusting a specific lever, releasing a special spring, or depressing a microswitch on the device’s main board.
This feature also provides the technical ability to react fast in the event that an attacker pulls the device from the wall or ceiling.
What is required to activate this option?
Theoretically, the client is not required to do anything because this option is set by default (in case of PPC). Regarding sensors, this is not frequently done. Why? Installers are not especially interested in “additional effort,” first and foremost because it increases financial expenditures. Which is especially disheartening given that this can be rapidly and inexpensively done in the great majority of wireless systems. The situation is different in wired ones, as a rule, because an additional cable must be pulled in order to “tamper”; the loop must then operate (unlike others) in 24/7 mode.
By the way, it used to be standard procedure for the system to be set up so that the siren would activate when a case was opened. Just be aware of this and, if you see fit, request that it be put into practice when performing installation work or enhancing an existing system.
In businesses, offices, and warehouses, security devices are installed away from entrances, indoors, in closets, or in difficult-to-reach places. In general, it is not conventional to install security devices in places where outsiders may access them. In other words, it should be accessible but also placed where it cannot be done quickly or quietly (but it is still vital to give room for convenient maintenance, such as battery replacement).
Another less obvious reason for not installing the device near the entrance is that it would make life difficult for anyone attempting to influence the stability of work from the outside, for instance by using a “white noise generator” that could impede data transfer or completely drown out equipment.
How to make the tamper unusable
Modern security systems include a remote control. The condition of the batteries must first be verified.
You must now enter device maintenance mode. The security system will not detect problems while operating in this mode. The integrity of loops needs to be checked after that. If you take the item apart, you can put it together yourself. To connect a defective cable for inspection, a wire might be helpful. This option enables. Remove the device’s lid, inspect loops, and change the batteries, all without being concerned about false positives.
Additionally, you should assess the tamper’s sensitivity and adjust it as appropriate. You must leave the maintenance mode once you have finished all the modifications. Low-sensitivity tamper won’t react to any change in the environment and will accidentally press the button.
Depending on the manufacturer and configuration, the mode’s name could change. Before beginning any inspection work, it is advised that you read the instructions and maintenance guidelines. In the Smart Mode module of some devices, a specialized mobile app can be used to change this setting.
