Frequently asked questions

No. Everything works on its own, right out of the box. There are no accounts to set up, no monthly fees, and nothing connected to the internet to hack.

One TremShield Vibration Alarm is $29.99, and the price per alarm drops as you buy more: $24.99 each for two or three, $19.99 each for four or five, and $16.50 each for six or more, so six cost $99. Two or more come with the Home Security Guide, four or five add a free no-drill window lock, and six or more add two.

Most of the range installs without drilling and comes off clean: the stick-on alarms, the clamp-on window locks, the adjustable door security bar and the French door lock bar, among others. A few pieces screw in, such as the door strike plate kit, the door reinforcement lock, the keyed window lock, the window restrictor, the sash jammer and the garage door slide latch. Each product page says how it fits.

The TremShield Vibration Alarm sounds at 125dB. The entry alarms reach up to 125dB, the door stop alarm 120dB and the personal safety alarm 130dB.
