4K DVR Security System, 8 and 16 Channel Camera Kits

DVR Camera Systems for Every Property Size

4 Camera DVR System

A 4 camera DVR security system includes a hybrid recorder, four 4K analog cameras, and a pre-installed hard drive. These kits cover residential properties and small commercial spaces where BNC coaxial cable is already in place or a new low-cost cable run is practical.

8 Channel DVR System

An 8 camera DVR security system expands coverage across a mid-size property from a single recorder. The hybrid DVR supports up to 8 analog BNC cameras plus 4 IP cameras for 12 total channels, giving you room to add cameras later without replacing the recorder. Each kit includes pre-installed storage and 4K analog cameras with color night vision and AI detection.

16 Channel DVR System

A 16 camera DVR security system covers large properties, warehouses, retail stores, and multi-building sites from one recorder. The hybrid DVR supports up to 16 analog cameras plus 8 IP cameras for 24 total channels. Pre-installed storage and 4K cameras with AI detection are included in every kit.

Why Choose a DVR Security System

A wired DVR security camera system does not depend on a wireless signal. Cameras connect directly through coaxial BNC cable, and the recorder stores footage locally on a pre-installed hard drive. There are no monthly subscription fees and no cloud storage required. AI detection identifies humans and vehicles and filters out false alerts from trees, headlights, and animals. Color night vision produces clear full-color video in low-light conditions and switches to infrared in complete darkness. Audio recording comes included on compatible camera models. The system connects to the Camius View app through your router for remote viewing on iOS and Android devices without a subscription.

4K DVR Systems with Storage and Audio

Every DVR security system kit from Camius ships with a pre-installed surveillance-grade hard drive included WD Purple, Seagate Skyhawk and Toshiba Surveillance Pro. Storage options include 3TB, 4TB, 8TB and 16TB drives depending on the kit. Recording runs 24/7 across all channels simultaneously. Audio recording is supported on cameras with a built-in microphone. Video output connects to a monitor through HDMI at 4K resolution or through VGA at 1080p. Security DVR recorders also supports connection to a PC or Mac through the Camius VMS software for professional multi-site monitoring. Use the Camius storage calculator on the support page to estimate how many days of footage your chosen storage configuration retains based on your camera count and recording resolution.

Expand with CCTV DVR Cameras

Camius hybrid DVR recorders support both analog BNC cameras and IP cameras on the same system. If you start with 4 analog cameras on an 8 channel recorder, you add up to 4 more analog cameras or up to 4 IP cameras to fill the remaining channels. For analog expansion, add compatible 4K analog surveillance cameras through the BNC input ports. For IP expansion, connect additional cameras through your network switch into the IP channel inputs. Browse compatible add-on cameras on the DVR system accessories page. This hybrid design protects your investment by letting you upgrade individual cameras without replacing the entire recorder.

DVR Security Systems for Businesses

Businesses with existing coaxial cable infrastructure get the most value from a DVR security system. Retail stores, restaurants, warehouses, property management companies, and churches all operate DVR systems where the camera runs are already in place from a previous installation. The hybrid recorder supports mixed camera types, so a business upgrading from older analog cameras adds higher-resolution IP cameras to specific high-value areas like cash registers or server rooms without replacing the full system. Remote access through the Camius View app lets managers and security staff monitor multiple locations from one device without paying per-location subscription fees. For properties requiring more than 24 analog and IP channels, consider Camius PoE NVR systems with 32 channel NVR or contact Camius support to discuss multi-recorder configurations

FAQs About DVR Security Systems

What is a DVR security system?

A DVR security system records video from analog coaxial cameras to a local digital video recorder. The recorder connects to cameras through BNC cables and stores footage on a pre-installed surveillance hard drive. Recording runs continuously without internet access. You watch live and recorded footage on a monitor connected to the DVR’s HDMI output, or through the Camius View app on your phone or tablet, PC or Mac computer and even a web browser after connecting the DVR to your router.

What is better, NVR or DVR security system?

DVR systems use analog coaxial cameras and work best on properties where coax cable is already installed. NVR systems use PoE IP cameras over Ethernet cable and deliver higher per-camera resolution with built-in two-way audio on compatible models. DVR systems cost less per camera on existing coax infrastructure. NVR systems fit new installations where Ethernet is the preferred cable type. If your building has coax cable from a previous system, a DVR security system saves the full cost of rewiring. If you are starting from a clean installation, a PoE NVR system gives you more resolution and audio options per camera, unlimited AI detection. Browse Camius PoE NVR systems to compare both options side by side.

Do DVR cameras need internet?

No. A DVR security system records to a local hard drive and does not need internet access to function. The recorder stores footage on the pre-installed hard drive at all times. You need an active internet connection only when accessing the system remotely through the Camius View app on your phone. If your internet goes down, recording continues without interruption.

What is the best DVR for security cameras?

The right DVR depends on how many cameras you need now and how many you plan to add. The 8 channel hybrid DVR supports up to 8 analog cameras plus 4 IP cameras for 12 total channels and works for homes, small businesses, and mid-size commercial properties. The 16 channel hybrid DVR supports up to 16 analog cameras plus 8 IP cameras for 24 total channels and fits warehouses, retail chains, and larger commercial sites. All Camius DVR recorders deliver 4K output through HDMI, AI detection, and pre-installed storage. Review the 8 channel DVR systems and 16 channel DVR camera systems pages to compare kit options by camera count.

Does a Camius DVR support IP cameras?

Yes. All Camius DVR recorders are hybrid models. The 8 channel DVR supports 8 analog BNC cameras plus 4 IP cameras, giving 12 total channels. The 16 channel DVR supports 16 analog BNC cameras plus 8 IP cameras, giving 24 total channels. IP cameras connect through your network switch into the IP channel inputs on the recorder, not through BNC. This lets you use higher-resolution IP cameras for specific areas while keeping existing analog cameras elsewhere on the same system.

How do I view my DVR security system remotely?

Connect the DVR to your home or business router using the included Ethernet cable. Download the Camius View app on your iOS or Android device and follow the setup steps in the quick start guide. The app gives you live view, playback of recorded footage, and push notifications for AI detection events. For viewing on a PC or Mac, download the Camius VMS software from the support page. Both options work without a monthly subscription fee.

How much storage does a DVR need?

Storage depends on camera count, recording resolution, and how many days of footage you want to retain. Camius DVR kits ship with pre-installed 3TB, 4TB, 8TB, and 16TB surveillance-grade hard drives. A 4TB drive typically covers 8 cameras recording continuously for 20 to 30 days at standard resolution settings. An 8TB drive extends retention for the same system to approximately 40 to 60 days. Motion-triggered recording extends retention further by reducing the amount of footage stored during inactive periods. Contact Camius if you need a footage retention estimate for your business and we will provide one based on your specific camera count and resolution.

Are Camius DVR systems NDAA compliant?

Yes. All Camius DVR systems and compatible cameras are NDAA compliant and approved for residential, commercial, and regulated environments.

Are DVR systems good for businesses?

DVR security systems are a practical choice for businesses with existing coaxial cable infrastructure. Retail stores, restaurants, warehouses, and property management companies use DVR systems to record 4K video across multiple cameras without monthly fees. The hybrid recorder adds IP cameras alongside analog cameras, so businesses upgrade specific areas without replacing the full system. Remote access through the Camius View app lets owners and security managers monitor locations from any phone or tablet. For large commercial sites requiring coverage across more than 16 analog camera positions, a 16 channel DVR kit supports up to 24 total cameras on a single recorder.

What is the best DVR security system for home use?

The best DVR security system for a home depends on the number of entry points and camera positions you need to cover. A 4 camera kit covers a standard residential property with front, back, driveway, and side yard coverage. An 8 camera kit covers larger homes, corner lots, or properties with detached garages and outbuildings. Camius 8 channel hybrid kits include a DVR recorder, 4K analog cameras, and a pre-installed hard drive. All kits record continuously without a subscription, work with existing coax cable, and support remote viewing through the Camius View app on your phone.

Do Camius DVR systems include a monitor?

Camius DVR security system kits do not include a monitor. The DVR connects to any monitor or TV with an HDMI port for 4K output or a VGA port for 1080p output. A standard HDMI monitor or any HD television works with the system. You purchase the monitor separately based on your screen size preference and mounting location.
