Security Cameras Systems

Crest lock Co. has been providing security camera systems and service for the last 23 years. We are one of the leading integrators in Baltimore Maryland area specializing in IP based systems for the last 10 years.

We are very particular about the companies we choose to represent and recommend to our clients. We test all system in house and make su re they meet our requirement before we will recommend then to are clients. In order for us to recommend a system it must be a system we would install and use for our own security. These are the following manufactures and VMS software systems.

Crest Lock prides ourselves in taking the time to be on top of all the upcoming technology and new products that hit the market. Although we know there are a lot of options out there, we bring everything we sell in house and test it before we recommend it to you. We take the time to test the system and all of its features so if a problem arises we can provide better service. We work directly with the manufacturers to offer our feedback, along with customer’s requests, and any issues or concerns that may need to be addressed. We offer a quick response time with remote support and on-site service. Our staff is not only trained on what to sell, but also how to install it and how it works from the inside out.  We know that having so many options for your security needs can be overwhelming.  That is why we have fully operational demo systems you can try before you make your decision.  You can come visit our state of the art showroom or we can bring our mobile showroom to you.   Before you buy off a brochure, call and ask to see a working system today!
