"We experienced beeping coming from our key pads on our ADT system. Certain zones were reported to check. We replaced batteries in the smoke detectors but that did not resolve our problem. Called Maximus Security, Kevin performed a complete system check. Found our back up battery was low on reserve power and replaced. Also rebooted system and performed certain coding that resolved our issues. All this for a very reasonable charge. What’s better, we got a call from Kevin a week later as a follow up call just to check if all was well. 5 star service!"

"Pete came out and did exactly what he said he would do. He was quick, responsive and came when he said he would come, which is hard to find these days. I plan on using Texas Made Security again for other projects that may come up. Thank you for a job well done!"

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.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.

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.
