How We Got Started

I chose to work in this industry because it blends my two passions; advanced technologies and property protection. In 2012, TCI began as a one man venture and organically grew into a 7 day a week operation with multiple full-time technicians in the first year alone. Our teams focus primarily on project-based services such as HD surveillance system integrations in homes and businesses. TCI remains the leading brand in multimedia and security solutions in Southern California thanks to our highest regard for quality components and unparalleled customer service. Any questions? Feel free to give us a call today!.

We started in this industry in 2012.

Install, Service, or Repair Surveillance Cameras - For Business

I called, sent the guy pictures of my current system. For me it was a replacement job and he quoted me. Came when scheduled and executed professionally. He charged me per the quote and was done with it. It was not rushed. I would highly recommend them and would definitely do business with them again.

Gabriel and the team at TCI are the best in the business. My project in Altadena was complex, with a large number of cameras (some up to 250 feet from the house), electronic gate latch, multiple monitors. TCI worked with me over time to grow my system to meet my needs. TCI was immediately responsive to request for service calls, and always answered all of my questions, provided detailed demos and instruction, and went above and beyond to ensure that I was satisfied. It was a great experience and I highly recommend TCI.

Gabriel and his team always do an excellent job. We have been working for together for about 4 years now. Their work is great and long lasting. We have transitioned to different yards and they always make the transitions very easy.

Bobby and Jose did an amazing job installing our cameras and NVR system. Bobby helped us set up our DMSS app, customized our settings and menu options. Once finished, all installation areas were cleaned and organized. Both Bobby and Jose were very polite, professional and addressed any customer concerns before leaving.

We were in need of a rock solid, comprehensive home security system a few years ago and we are thrilled with the experience, skill, and customer service received from TCI. They are the best at setting up a full home security system and a real pleasure to work with . Over the past few years they have been easy get in touch with, helpful with minor changes to our set up and always eager to assist as needed. We highly recommend them !

Long Beach Home Security Companies

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

To find more licensing information for your state, visit our Licensing Requirements page. Note that some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

HomeAdvisor's Screening Process

HomeAdvisor uses an extensive screening process to screen businesses and business owners/principals. We perform this screening when a business applies to join our network and, if the business is accepted, whenever concerns are brought to our attention. If you have concerns that a pro in our network doesn't meet these standards, please contact us to investigate. We're committed to maintaining a network of trusted home service businesses, and those who don't meet our criteria will be rejected or promptly removed from our network.

Criminal Background Check

Who does HomeAdvisor background check?

The owner or principal of each business in HomeAdvisor's network (with the exception of Corporate Accounts) must pass a background check. Unfortunately, we cannot perform a background check on every employee of a business—the background checks are performed only on the owner or principal. As always, we recommend that you conduct your own research on the businesses you hire, including making inquiries directly with the businesses regarding their employee background check policies.

What does the background check cover?

We use a third-party vendor to conduct a criminal records search in the county in which the business owner or principal works. Our third-party vendor uses a national criminal database ("NCD") to screen service professionals. Business owners or principals with felony arrests that carry a pending decision or who are convicted of felonies in the past 7 years ago will not be admitted to the network. Businesses or owners convicted misdemeanors or felonies, or who have dismissed charges or arrests on their records involving rape/incest, sex offenses, or lewd and lascivious behavior at any point in time will not be admitted to our network.

Our background check does not exclude service professionals unless the crime at issue is a felony.

*The comprehensiveness of the NCD varies by state. Please be aware that the reporting in the NCD is particularly limited in the following states: AL, CO, DE, GA, ID, IL, KS, LA, ME, MA, MI, MS, MT, NE, NV, NH, NM, SD, UT, VA, VT, and WY. After initial admission to the HomeAdvisor network, businesses are re-screened if a concern is reported to HomeAdvisor.

Corporate Accounts

Some businesses are employees, franchisees, dealers or independent contractors ("Corporate SP's") of larger national or "Corporate Accounts". When this is the case, we may match you with the Corporate Account or with one of their Corporate businesses. The above screening process does not apply to Corporate Accounts, as HomeAdvisor does not screen Corporate Accounts or Corporate businesses.

Verify Trade License HomeAdvisor checks to see if the business carries the appropriate state-level license. Verify Insurance As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services. Verification of State Business Filings For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located. Criminal Records Search HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business. Sex Offender Search We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located. Bankruptcy Search We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them. Legal Search for Civil Judgments We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them. Liens Search We use 3rd party data sources to check the principal/owner of the business for liens placed against them. Identity Verification (SSN) HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities. Identity Verification (Reverse Phone Lookup) We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
