Home Security Systems questions, answered by experts

Each has its use, depending on the scenario. Security doors are primarily intended to keep people out of the home, while storm doors are used to protect the home from extreme weather. Both tend to be made from heavy-duty metal and may include glass panels to allow light to enter the home. Storm doors can feature mesh screens, just like screen doors, to allow for increased ventilation and to keep out pests. Security doors rarely, if ever, have mesh screens.

With the popularity of DIY security cameras and video surveillance systems, it’s important to understand the benefits and potential drawbacks to decide if it’s the right choice for you. Advantages and disadvantages include:

Pros

  • Video footage readily available

  • Reduced home insurance

  • Save on labor costs by installing security cameras yourself

  • Wireless systems are easy to move and set up

  • Monitor from your smartphone

  • Avoid false alarms

Cons

  • Features may be vulnerable to hackers

  • No direct link to authorities

  • Risk of installing the system improperly, reducing its effectiveness

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

In general, daytime visibility for security cameras ranges from 10 to 70 feet. Higher-end cameras may have night vision that records 100 to 200 feet out. When shopping for any type of security camera, it's important to pay attention to focal length, resolution, and infrared technology to get an idea of the depth and crispness that will be used when capturing images.

You should be able to use your smart doorbell and access your video feed without a subscription. Subscriptions give you special features, such as night vision, downloading, and automatically saving footage for a set amount of days. It’s a good idea to compare plans among different providers before you commit.
