Lithium sensor batteries, for example, can last three to five years. When they do run low, the system lets you know well in advance. Choose a controller with back up battery so the system will stay active in the event of a power outage or if the Internet is down. If you will be installing smoke alarms you’ll need the extra power of a 24 hour battery back up, not the 4 hour back up offered by many manufacturers. THE COST FOR SECURITY There are two costs to keep in mind when shopping for a home security system. The first is for the equipment and the installation, if you’re having it done by a professional. It can run from a few hundred dollars for a basic installation or less that half of that if you install it yourself to north of $1000 for a full feature system with specialized sensors and wireless smoke and CO detectors. The second is the monthly service charge that includes fees for software driven features and central station monitoring. It typically ranges between $35 and $60 per month. Some dealers, much like mobile phone and cable TV companies, will reduce the installation cost in return for a multi year contract.

Nothing indicates that Vivint needs some form of document stating the military member is living “on base. ”You should also consider whether the external doors themselves are strong enough to withstand attack.
Security doors can be expensive, running into thousands for steel reinforced doors in steel frames. But there are cheaper options — a Burglarybuster Nightlock Pull Up Security Bar can be purchased for €69. This bar can be laid across external doors at night. It reinforces the lower part of the door and means efforts to knock it in will create far more noise — always effective in deterring burglars. Windows should be fitted with locks. For ease of use, you can arrange for all locks fitted to be opened with a single key. If you go to , there is a home security audit checklist on the site to help you identify potential weak areas in
your security and offer solutions. We've all had those moments: we're on our way to work or even on vacation and wondered if we locked the back door or forgot to turn off the lights. Home security systems are getting more sophisticated, and can now help give some extra peace of mind.
