"Felt kind of bad for the installer on the day he came to set up our alarm package. He was clearly brand new, and struggled a bit to get everything working correctly. However, he called his manager a few times to help with troubleshooting and in the end all got done. Took longer than it should have, but the gentleman was extremely nice and apologetic. They threw in a couple of extra motion sensors for the basement to make up for the long visit. Extremely nice touch and customer service. Still giving 5 stars."

"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

FAQs for alarm or security system installation projects in Los Angeles, CA

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
