Dual sensor smoke detectors include both ionization and photoelectric sensors, so they should adequately alert homeowners of a smoldering fire or a fire with active flames.Some safety organizations have previously recommended these smoke alarms, because they should cover a broad range of fires.hen smoke enters the chamber, it scatters the light, which then hits the sensor and triggers the alarm. Photoelectric smoke detectors typically respond faster to a fire in its early, smoldering stage â before the source of the fire bursts into flames.
There are two options for licensing Splunk Enterprise: 1  Perpetual license: Includes the full functionality of Splunk Enterprise and starts as low as $4,500 * for 1GB/day, plus annual support fees. 2  Term license: Provides the option of paying a yearly fee instead of the one-time perpetual license fee.
So it's the age-old question of weighing capabilities, or lack thereof, against costs. You can buy term-licensed Splunk Light starting at 1 GB-per-day capacity at $75 per month (with a one-year commitment and no additional support fees). You can also buy a perpetual license for $1,800, plus 20%-per-year maintenance. A Splunk Enterprise annual-term license starts at $1,800 at the 1 GB-per-day level, while the perpetual license at that capacity is $4,500, plus 20%-per-year maintenance.
