"These guys did the fire sprinklers for our home. They came in and did the project well. However, once they finished and finaled inspection, they are totally unresponsive. There's one fire sprinkler they never put a cap on. I've been trying for MONTHS to get them to put a cap on. They just shipped me a cap and said "do it yourself". I watched a youtube video, but something isn't fitting right, and I can't get the cap on. I feel it's not right that they can't even return to finish the job they started and assume that I need to become a sprinkler head expert myself and put on the cap. Hopefully after this review, they'll finally respond to me!"

Home Security Systems questions, answered by experts

Security cameras do not need wiring if they are wireless, meaning they are battery-operated and can connect through Wi-Fi. You’ll need to change the batteries on a wireless camera and ensure you have a steady connection to Wi-Fi for video storage. If you have a wired security camera, you’ll need to plug it into an outlet or other power source and a DVR device.

Strike plates and security plates are the same thing, but there are strike plates that offer more security than others. For the highest security, look for plates made of heavy-duty steel, reinforced strike plates thicker than regular ones, and extended strike plates. It’s much harder to break into a door with these strike plates because they hold up better to force from attempted entry.

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:

  • Video surveillance monitoring: $40–$65 per month

  • Smart home locks: $150

  • Smart home lighting: $15–$90

  • Smart smoke, fire, and carbon monoxide alarms: $35–$100

  • Smart thermostat: $130–$500

Insurance companies weigh the amount of potential liabilities on your property to increase (or decrease) the cost of your home insurance. They will use several factors to decide if there are more chances for peril or injury to take place at your home. These factors include your location (whether you live in an area with high risk for natural disasters), the age and condition of your home, and whether you have any “attractive nuisances”—features that both increase the aesthetic of your home and potential for injury—like a pool or treehouse. 

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.
