Spear Security
We chose Spear Security several years ago to use exclusively and we are extremely pleased with that decision. Their guards must interact with the public repeatedly on a daily basis at both our locations so it is vitally important that they are professional, both in appearance and actions, respectful and punctual. Spear Security takes great care and pride in providing us with guards that bring all the above to work each day. Additionally, we are extremely happy with Spear Security's management and administrative teams, they are very approachable, knowledgeable, and proactive to our needs. We definitely recommend Spear Security!

Hillquest Security and Patrol
About a month ago I was looking for a good security company to hire for my grandparents 40th anniversary.HillQuest Security and Patrol was recommended to me by a friend as the best in the area,so I called them right away.The day of the event they arrived half an hour early and were very polite and professional. The two guards that came were awesome and very polite.At the end of the event they even helped us break down all tables and chairs, that was extra good for us.. I definitely will be calling these guys again for future events. I recommend anybody looking for security call these guys up. 10 stars for sure!!

Hillquest Security and Patrol
I have been living at an apartment complex located in the East Side of San Jose for the past year. Before the management hired HillQuest Security, there were about 5-10 car break-ins a week. Now, there is zero. The staff at Hillquest Security is friendly, professional, and quick to respond when a crisis is taking place. They take a lot of pride in the type of work they do and are committed to excellence. I feel much safer knowing that HillQuest Security and Patrol is guarding the apartment complex. I have only good things to say about them, and I highly recommend their services.

Spear Security
We are very pleased as long time customers of Spear Security. Their guards are all very courteous, professional, punctual, and trust worthy. They have also provided us with a new technology which has helped us go green in an effort to cut back on our paper usage. This system also tracks guards activity, and gives us more value for our money. We would highly recommend Spear Security and thank them for their service!

American Asset Protection
I highly recommend American Asset Protection. They have Reliable and Accountable Security Officers that have helped keep my business safe and secure with around the clock Officers. In the past I had used other security guard companies but none of them meet the high expectations and ethics that American Asset Protection has provided for me and my business.

Hillquest Security and Patrol
Beyond satisfied with the service that Hill Quest provided. There was an incident at my last art show where one of my paintings got stolen so I decided, maybe I needed security now. So I contacted Hill Quest and they let me get any guy I wanted who best fit for the job in my eyes. So i got two guys who where so kind and did the job perfectly!

United Guard Security
UGS was an awesome first experience with a security type company. They performed a lot higher than I expected them to. We were given a detailed report of their patrol and they addressed small details that could become problematic down the road. Very knowledgeable and logical security company. We will definitely be using them regularly!

United Guard Security
Definitely happy I decided to hire United Guard Security over the other local companies in the vicinity. They were professional on duty and were never caught slacking off. They issued full reports of their patrol and did an overall great job. Keep up the good work and our company will never have a problem with calling you guys back!
Tips & Advices
  • Cameras
  • Motion sensors
  • Alarms
  • Smoke, CO2, and flood detectors
  • Flashlights
  • Panic buttons
  • Door and window stoppers
  • Spot lights/floodlights
  • Etched window glass
  • Combination safe
  • reinforced locks
  • Placing signs and sticker for security systems outside home
  • Personal safety items (firearms, stun guns, pepper spray, batons, etc.)
No, it is possible to install a home alarm system yourself. Some systems are specifically designed to be installed by homeowners. These systems are often cheaper and more customizable. However some systems require the expertise of a professional and installation should be left up to them to avoid making any errors. Review the specifications of the system and/or contact the manufacturer if you are unsure about its installation requirements.
  • Easy and inexpensive to install and does not require any drilling or modification of the home.
  • Does not require a landline.
  • Can be taken from one home to another during change of residence.
  • Can be combined with a hardwired system.
  • No need to change any batteries, as with wireless systems
  • No interference from other signals
  • All hardwired systems run on essentially the same technology so products and services from different companies will be compatible with each other.
  • If moving to a home with a hardwired system already installed, you can save money by bypassing installation costs.
  • New security equipment for these systems is less expensive than for wireless systems.
  • Can be combined with a wireless system
  • Hardwired: A system that uses cables to connect all sensors to a central control panel within your home. The cables are usually installed within the walls or floorboards of your home. The control panel then uses your home’s landline connection to call for assistance (police, fire, medic).
  • Wireless: A system which uses wireless technology (wi-fi) to connect all sensors to your home’s central control panel. The panel uses the established network to communicate with the outside for assistance.
  • A combination of hardwired and wireless: Custom systems can be configured to have a home totally hardwired and equipped with wireless outside communication (no landline), or have a totally wireless home and hardwired outside communication.
