"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."

"I have investigated many companies and chose 1st Security because of such good reviews. 
Well I must add my excellent review for this company. Larry installed everything for us and he was 
very knowledgeable and made sure everything worked perfectly before he left.  
If I have questions he answers them right away. 
I would absolutely recommend this company to do your work. "

"They system was installed for the basic, but anything that you wanted needed to be higher upgraded require alot of extra money for every upgrade.
 The 36.99 monthly fee was for only if your system is connected to a landline. I didnnt notice that they charge me $44.99 until my 1st month fee. Thats when I was told that they charge $44.99 because the alram was connected to my cable line instead. I was unaware of the different charges. When tec came out he didnt show up to fix the corrected. Had to call the main company for the no show. So they schedule another appointment and offered 2 window alarms to fix the correction but my bill still is $44.99. Default is that since I didnt have extra money to upgrade to the Pulse, you dont know if you turn the alarm to your house properly. I called the 800 number and they cant tell either!

Home Security Systems FAQs, answered by experts

A steel door that's been toughened up with extra materials creates the perfect barrier. These bad boys are way stronger than your typical wooden or fiberglass doors, making them a fantastic choice for folks who want that extra layer of security for their homes. So, if you're all about keeping things super secure, a reinforced steel door will cost you more, but it is your best bet.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Depending on your needs and wants, investing in a security door can be well worth the cost. Now that you know the pros and cons, you can decide if it’s a purchase that makes sense for your family. If you’re ready to have one installed in your home, look into security door installers in your area.

Whether a security system or security cameras is a better choice for you depends on your needs and preferred comfort level. A security system can cost more depending on the features you choose, but it’s a more proactive and protective approach to home security by alerting you and authorities of any emergencies. Using a security camera system is a more reactive approach because while you can monitor the camera footage, it does not alert the proper authorities for you.

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.
