    HD commercial grade security camera

    Halcyon installed video surveillance and security alarm to protect my business, we chose to go with them after comparing with other quotes the been ridiculously higher and with a long term contract, the technicians crew have been very professional and perform a very clean installation, no visible wires at any off the retail areas at all! The burglar alarm is very easy to use and I can control alerts or manage notifications anywhere, I'm very happy with the work and the product. Already booked upgrade for my home system. Thank you to the best security experts in San Diego!

    Illegal dumping 1 (03/17/19)

    My Oceanside triplex had two problems: Trespassers loitering in the laundry room and illegal dumping in the alley. I called Halcyon Technologies to address these issues. They are a major player in San Diego for CCTV. Halcyon was very professional. They surveyed the property and recommended a solution. The cameras were installed within a week for a reasonable cost. Technical support has been great. Everything is working. The app is easy to use and, with Halcyon's help, I was able to get the cameras working on a personal computer (using the IE browser). There are no subscription fees for the Halcyon cameras. My only ongoing costs are for electricity and broadband Internet. Within two weeks of installation, I was able to have my first illegal dumper prosecuted. At the present time, I am monitoring my late-night laundry room visitor.

    My wife and I are very happy with the items that were installed in our house. The sales person and…read morethe installation person were both very helpful and friendly. Whenever there is an issue, I call my ADT Representative, Kyle, and he takes care of it for me. I recommend to all my friends.

    If I could give ADT zero stars, I would. I've been a loyal customer for over 12 years, but their…read morerecent service has been an absolute disaster and a complete betrayal of my trust. As a senior citizen, I rely on my home security system for peace of mind--but for months, my ADT system has been non-functional. I made dozens of phone calls, each taking up to an hour just to get past the maze of hold music and transfers. After finally reaching someone who could help, I was told I needed a brand-new system and a new contract. So I agreed, trusting that this would finally resolve the issue. Wrong. A technician came to my home and spent over 6 hours trying to install the system--only to tell me it wouldn't work without new motion sensors, which I had to pay for out of pocket. I was also misled into thinking the new system would work with my existing cameras. It doesn't. The best part? After all that time, effort, and money--the new system doesn't even work. It constantly malfunctions, giving false alerts and telling me doors are open when they're not. Total failure. This is a company that profits off fear, offers misleading sales pitches, fails to deliver basic service, and then has the audacity to lock you into a contract. Their "customer service" is a joke--disorganized, evasive, and completely indifferent to your time and safety. Do yourself a favor--don't walk, RUN from ADT.
