Modern time delay combination locks can have many functions such as multiple different codes, pre-set time lock settings (open and close times), pre-set vacation times (e.g. Christmas Day), dual code facility, and a full audit trail providing a detailed record of the lock history showing who opened the lock, when and how long it was open.

When the change in field strength weakens due to the presence of an object and reaches a pre-set lower threshold, an alarm condition is generated. The system is covert after installation. The surrounding soil must offer good drainage in order to avoid nuisance alarms.
A watchdog timer (WDT, or simply a watchdog), sometimes called a computer operating properly timer (COP timer), [1] is an electronic or software timer that is used to detect and recover from computer malfunctions. Watchdog timers are widely used in computers to facilitate automatic correction of temporary hardware faults, and to prevent errant ...
Security as a service : These security services often include authentication, anti-virus, anti-malware/spyware, intrusion detection, penetration testing and security event management, among others. In practice many products in this area will have a mix of these functions, so there will often be some overlap – and many commercial vendors also ...
Time-triggered systems can be viewed as a subset of a more general event-triggered (ET) system architecture (see event-driven programming).. Implementation of an ET system will typically involve use of multiple interrupts, each associated with specific periodic events (such as timer overflows) or aperiodic events (such as the arrival of messages over a communication bus at random points in time).
The key feature of a Security Event Management tool is the ability to analyse the collected logs to highlight events or behaviors of interest, for example an Administrator or Super User logon, outside of normal business hours. This may include attaching contextual information, such as host information (value, owner, location, etc.), identity ...
Event logging: regardless of the event type, a good practice should be to record the event and the actions taken. The event can be logged as an Event Record or it can be left as an entry in the system log of the device. Alert and human intervention: for events that requires human intervention, the event needs to be escalated.
If the router detects that a network is unreachable, the timer is started. The router will then wait a preset number of seconds until the network is stable. When the timer expires, the router will then receive its routing updates from other routers. For example, in RIP the default holddown timer is set to 180 seconds.
