"SafeStreets Home Security was a lifesaver! They had to troubleshoot my 3 floor townhouse unit, requiring many trips up and down the stairs. Finally determined that I needed an entire new alarm system but had all the parts and equipment available. Helped me program the app and set my security codes."

"We moved to Chevy Chase MD. I contacted three different security companies. By far Ultra Guard Security was the best. Andy was very knowable about security systems and not pushy at all. If looking for security system give them a call. You will be pleased."

"Abstract was great to work with. I had one vision for the project, and they convinced me to go another way. They were the only company that actually asked me questions about what I wanted from the system, and took time to talk to me what my best options were. From the few proposals I received, they were by far the cheapest for parts and labor. But the end product is great - we've been happy with how the cameras look like and what they are able to record. Overall, very highly recommended for professionalism, care in working with the customer, and price for quality."

"Steven and his team were simply exceptional! From the very beginning, they were responsive, professional and clearly knowledgeable about the security system. They were proactive in scheduling, reached out to confirm the night before, and even on the morning of the service, reached out to let me know they were on their way, and would arrive on time!! The installation work they did was superb! High quality work, very clean and professional and even went above what was expected to correct other issues left by the prior security company. I simply cannot say enough good things about Steven and his team! If you want highly professional, on time and high value security work, there is no other choice. I am happy to personally speak to any prospective client about my endorsement. That’s how strongly I feel about what I’ve said here. Thank you Steven and Access Pro!!!"

"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

Home Security Systems FAQs, answered by experts

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

Professional home automation services can include automation for nearly anything in your home, so the possibilities are endless. Some of the more common things homeowners use automation for include the following:

  • Heating and cooling for automatic comfort

  • Security cameras and emergency call systems

  • Door and window sensors to detect opening, closing, and break-ins

  • Solar system automation to maximize energy savings

  • Automatic door locks

  • Garage door openers

  • Speaker systems

  • Lighting

  • Appliances

  • Smoke and CO detectors

  • Blinds and other window coverings

  • Lawn irrigation systems

  • Water monitoring

DIY is possible for wireless cameras, but professionals ensure optimal angles, security integration, and network stability.

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.

It is possible to spend only $30 on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion.
