"I purchased a house with an existing security system. JR came out and was able to tell me exactly what I needed to update the system. During the installation the guys walked me through how to work everything. Very happy I went with DST Security."

"My security cameras would lose video feed especially at night. I initially thought the cameras were bad and needed to be replaced. Mr. Azim arrived the same day I requested service and was able to identify and correct the problem quickly. I am so grateful to have the use of my cameras. I truly depend on them as do my neighbors and the police. I highly recommend Mr Azim and would hire him again. He was very professional, thorough and answers all my questions."

"The owner of Electronics 9-1-1 installed an eight-camera home security system in my home. The entire experience, from initial consultation to finished product, was the model on which all other advertisers' services on Homeadvisor should be based! The company owner's recommendations about installation techniques, technical knowledge and considerations, equipment capabilities, scheduling accommodations, and modifications in mid-installation to overcome unforeseen issues were all spot-on, and resulted in a system that exceeded every expectation. Would use Electronics 9-1-1 again in a heartbeat, and it is a pleasure to recommend them to anyone needing security system installation or service of the highest quality."

Home Security Systems FAQs, answered by experts

A home security system can be a worthwhile investment for several reasons. Financially, it may qualify you for a discount of up to 20% on your home insurance premiums, which can help offset the initial setup costs and any ongoing monitoring or subscription fees. For many, the primary benefit is the peace of mind that comes with enhanced security, especially for those living in areas with higher crime rates. Ultimately, whether a system is worth it depends on your personal preferences, the value of the assets you wish to protect, and your overall safety concerns.

Understanding the pros and cons of installing a home security system is the first step to deciding which one is right for you. A few of the advantages and disadvantages include:

Pros

  • Added security for your household

  • Reduced home insurance premiums

  • Many smart home integrations available

  • Security companies can monitor your home 

Cons

  • Expensive setup costs 

  • Subscription costs can add up quickly

  • Features may be vulnerable to hackers

  • Weak signal reduces the security of a wireless system

If you're wondering what you should do with your old security alarm system after installing a new one, one option is to properly dispose of it at an electronics collection facility. Otherwise, if your old system is still in good shape, you can also donate it for someone else to use in their home.

Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

You should always install cameras at exterior doors and windows. Other areas where you should place cameras are your front and back yards, the garage and driveway, common living areas, hallways and staircases, and the basement. Remember, you can start with a small Wi-Fi security camera system and always add more cameras if needed.
