Ring's $179.99 Battery Doorbell 2K Plus runs on a removable pack and needs no existing wiring, but video history sits behind a plan that starts at $4.99 a month.
UL-rated for 30 minutes at 1550°F and ETL-verified against 72 hours of flood, sized for passports and drives. SentrySafe prints a $50–$100 band instead of a price, so the ratings do the talking.
A 3-A:40-B:C single-use extinguisher with 5.5 lb of agent, a 12-year design life and a $55.97 MSRP. Bigger than the Living Area unit in every figure that matters, and heavier to hang.
A $24.99 battery-only carbon monoxide alarm with an electrochemical sensor, a user-replaced 9V battery, an 85 dB horn and a five-chirp end-of-life signal; the CO400XP SKU was backordered on firstalert.com when we checked.
A $29.99 ionization smoke alarm with a sealed lithium battery that First Alert rates for ten years, a five-chirp end-of-life signal, and a 10-year limited warranty; the listing showed it backordered on the check date.
The H5058 three-pack is $39.99 for three battery alarms at $13.33 each. They sound at up to 100 dB in the room and send nothing to a phone until Govee's separate gateway joins.
