Already have a security system? We can upgrade or take over compatible equipment.
Many Duncan homes and businesses already have security equipment installed, but older hardware or limited features can reduce overall performance. Shadow Security reviews your current setup to determine what can be reused and where updates would strengthen reliability. When equipment is in good condition, we can often connect it to modern monitoring and management tools with minimal interruption. If upgrades are recommended, we outline practical options that improve system performance without unnecessary replacements.

Definitely a 10 out of 10!! Was one of the best experiences I've had dealing with a business!! I used Shadow Security to have cameras and an alarm system installed! Couldn't be happier! Josh did the installation for me. He made the whole process of picking out a package and what was needed very stress free and easy. He's very knowledgeable about security and the product he offers. Very respectful and listened to what I was needing/wanting out of a security system/cameras. He then took that and came up with a great product/package that met my needs. I'm very pleased with the product I have! Would definitely recommend Josh and Shadow Security to my family and friends!
Joshua has provided the most excellent experience with our security system installation! I personally give him a great endorsement for those looking to install security! We are 100% satisfied with his work as well as his customer service! Give him a call! You won't be disappointed!
I have their home security system installed at my home and my business. They helped me choose the right security cameras and handled the entire security system installation for me. I'm happy with the products and service they provided and the tech was very knowledgeable. Would recommend for sure. Thanks guys.
We had a great experience using Shadow Security! Everything was installed impeccably well and to our absolute satisfaction. I had many questions and everything was explained extremely well and easy to understand! Thank you for your service!!!
Shadow Security installed cameras at our business almost two years ago, and the system has worked very well with no issues. Joshua was great to work with, helping us get the best coverage of our space and looking for ways for us to save money where possible. One of our cameras recently went out due to a damaged network cable, and Joshua came out the next day to fix it for us. I would highly recommend Shadow Security for your home or business!
Josh from Shadow Security was amazing, took his time to explain everything to me and my wife. Amazing company and top of the line equipment.
Shadow Security is a great company! Took care of my security system and security cameras. From start to finish I felt respected and cared for like part of their family. They taught me how to use everything with ease. The system is top of the line and professionally installed!
