What is the difference between a DVR, NVR and VMS?

A DVR (digital video recorder) records analog cameras over coax cable. An NVR (network video recorder) records IP cameras over your network. A VMS (video management system) is software running on a server that manages and records many cameras, often across several sites, with more control over users, search and storage.

TechCore plans, installs and supports DVR, NVR and VMS servers for businesses in Middle Tennessee and the Chattanooga area, sized for your cameras, how long you need to keep video and who needs remote access.

What we plan and support

Recording that is there when you need it

A recorder that is undersized, out of space or quietly failing means missing video. We plan around how you will actually use it.

Recorder and server selection

The right DVR, NVR or VMS server for your current cameras, with room to add more.

Storage and retention

Hard drive capacity sized to the number of cameras, resolution and how many days of video you need to keep.

Camera and channel capacity

Enough channels and processing power for every camera, including higher resolution and analytics.

Remote access

Secure live viewing and playback from phones and computers for the people who need it.

User permissions

Separate accounts and access levels so managers, staff and investigators see only what they should.

Network and cybersecurity

Recorders set up on your network the right way by our IT team, coordinated with Turner Security, our sister security company.

Why it matters

Missing video usually means a recorder problem

When businesses go to pull footage and find nothing, the cause is usually the recorder: a full or failed drive, a lost network connection, or a system nobody has checked in months.

We size storage for the retention you need, check recorder health and resolve many recorder problems remotely through our help desk before a technician has to visit.

  • Retention sized to your needs
  • Secure remote viewing
  • User accounts and permissions
  • Most recorder issues fixed remotely

Common questions

Questions we hear a lot

Should my business use a DVR or an NVR?

If you have older analog cameras on coax cable, a DVR can keep them working. If you have or are moving to IP cameras, an NVR is the usual choice and supports higher resolution and more features. We review your cameras and recommend the right fit.

When does a business need a VMS server?

A VMS server makes sense for larger systems, multiple sites, or when you need more control over users, search and storage than a standard recorder offers.

How many days of video will my recorder keep?

It depends on the number of cameras, resolution, frame rate and drive capacity. We size storage to the number of days you need, and can add storage to many existing recorders.

Can I view my recorder from my phone?

Yes. We set up secure remote access so authorized users can watch live and play back video from a phone or computer.

My recorder stopped recording. What should I do?

Call or submit a service request. Our help desk can often find the cause remotely, such as a failed drive or lost connection, and schedule a technician if a part needs replacing.

Can a new recorder work with my existing cameras?

Often, yes. Many existing cameras can be moved to a new recorder or VMS. We check compatibility first and tell you if any cameras should be replaced.

We used Turner Security when our business transferred to a new location and they went above and beyond to make sure we were up and running for business as quickly as possible. Jamie, Mike, Reid, Nathan, Greg, TJ and Dan were all very polite, professional, and friendly. I highly recommend them for all your IT needs!

TechCore takes care of our IT and we could not be more pleased with Jamie, Chris and everyone at Turner Security. They are quick to respond and fix any IT issues.

MOV Ministry Men of Valor Google review, 5 stars

I am a manager for 4 locations of Express Employment Professionals and we've recently used TechCore for our phone service. Our installation was easy and fast! Jamie and Alex took extra care to make sure all of our needs were met in each office, they had everything installed and running on the same day and Alex has been incredibly helpful for any changes we've needed with staff changes. I would highly recommend TechCore's phone and networking service.
