alarm system home security
The distance from which your camera can record images in low to no light situations can have a great impact on its effectiveness if you want to capture activity after the sun sets. We’ve all dealt with photos that are too dark to make out any details. It’s frustrating when it’s a wedding photo, but it’s nerve racking when you’re trying to capture a face or license plate after a break in. Pay attention to the existing lighting in the areas where you want to install security cameras. Look for the
night vision
range of each camera and consider how much area you want to cover. And beware of using an indoor camera to look outside; they can’t usually capture images through a window or after dark.

wireless security system for home
Many of these cameras communicate via Wi Fi and only need hard wiring to their power source. Smaller cameras like video doorbells and peephole cameras frequently use batteries, which is even more user friendly. Outdoor security cameras can present more of a challenge, especially if the home’s exterior has limited power sources, if you don’t have many tools or if you are concerned about affecting your home’s appearance. In these cases, you may
want to hire a professional with experience on prior camera installs. Finally, there are some circumstances where you can’t install your own cameras. Many leading providers of monitored home security systems such as ADT and Vivint require professional installation to make sure everything is in working order. In these cases, a trained technician visits your house to relieve you of this responsibility altogether. If you’re dedicated to doing it yourself and you want a professionally monitored security system, you do have plenty of DIY options: SimpliSafe, Frontpoint and Protect America are all strong choices.

To start with, Frontpoint is the only home security system that is 100% wireless and 100% cellular. Why is this important?In a traditional, landline home security system, burglars can
disable the system simply by snipping phone lines or cutting cable wires, which renders the home security system powerless.
