Professional Wired CCTV Surveillance
HD CCTV Security Camera Systems with DVR Recording
Shop professional CCTV camera systems with wired HD or 4K-capable security cameras, compatible DVR recording, local video storage, night surveillance and remote viewing. These CCTV security systems are designed for businesses, warehouses, offices, retail stores, restaurants, schools, homes and other properties that want dependable wired surveillance without a required monthly cloud-storage subscription.
HD-over-coax technology is especially useful when suitable coaxial cable is already installed. Instead of replacing every cable run with Ethernet, many properties can upgrade older analog CCTV equipment to modern high-definition cameras and DVR recording while retaining compatible existing coax wiring.
Why Choose an HD CCTV Camera System?
A modern HD CCTV camera system combines wired security cameras with a digital video recorder to provide reliable local surveillance recording. Unlike older low-resolution analog systems, current HD-over-coax technology can deliver much sharper video while preserving the familiar coax-and-BNC wiring architecture used in traditional CCTV installations.
For properties that already have compatible coax wiring, this can make HD-over-coax CCTV systems an efficient way to improve image quality without rebuilding the entire surveillance infrastructure. You can retain local DVR storage, monitor cameras remotely and expand or replace individual cameras as needed.
Reuse Compatible Coax
Suitable existing coaxial cable may be reused when upgrading older analog CCTV cameras to higher-resolution surveillance.
HD & 4K-Capable Video
Choose cameras appropriate for entrances, parking areas, offices, warehouses, registers and other high-priority security locations.
Local DVR Recording
Store surveillance footage locally on a DVR hard drive with recording schedules and storage capacity selected for your property.
Remote Viewing
View live and recorded cameras remotely using compatible phone, tablet and computer applications.
HD CCTV Systems vs. IP Security Camera Systems
Both technologies provide professional wired surveillance, but they use different cabling and recording architectures. CCTV security camera systems typically connect cameras to a DVR using coaxial cable, while IP camera systems generally use Ethernet cabling, PoE cameras and an NVR.
HD CCTV is often a strong choice when you already have compatible coax wiring or prefer a traditional DVR-based design. For new Ethernet-based installations or customers wanting PoE networking and broader IP camera options, compare our IP security camera systems .

CCTV Camera System FAQs
What is an HD CCTV security camera system?
An HD CCTV system uses wired security cameras connected to a DVR, typically through coaxial cable, to provide local high-definition surveillance recording and remote viewing.
Can I reuse existing coax cable?
Often, yes. If the existing coaxial cable and connectors are in suitable condition and compatible with the equipment, they may be reused when upgrading an older analog CCTV installation.
Do CCTV camera systems require monthly fees?
CCTV Security Pros systems use local DVR recording and do not require a monthly cloud-storage subscription for normal recording and remote viewing.
Is CCTV or IP better for a new installation?
It depends on your wiring and project goals. HD-over-coax CCTV can be especially useful when compatible coax already exists, while IP and PoE systems are often a strong option for new Ethernet-based surveillance installations.
What comes with a complete CCTV system?
Package contents vary by system, but complete CCTV systems generally combine compatible security cameras, DVR recording equipment, cabling or connectivity accessories and the hardware required for the selected configuration.

What is "HD-CVI"
HD-CVI stands for High Definition Composite Video Interface. This technological terminology might sound intimidating, but let's simplify it. The "HD" signifies that these systems are designed for capturing and transmitting high-definition video footage. The unique advantage of HD-CVI systems over traditional analog cameras is that customers can get megapixel high definition video of up to 4K over standard coax BNC cable.
For example, many of our repeat customers have older analog systems with RG-59 coax cable in place. HD-CVI enables our customers to simply switch out the recorder and cameras while keeping their existing cable set up in place. It is as easy as connecting the HD DVR and the cameras to the existing cable. Instead of an analog signal, the cameras transmit a digital signal which makes the definition much better than older security cameras.
HD-CVI security cameras provide high-resolution video footage and long-range transmission capabilities. They offer advantages over traditional analog cameras, such as single cable transmission of video, power, and audio and higher definition of up to 4K. Especially if you have wires in place from an older analog system consider upgrading to a HD-CVI security camera system from us for superior and much clearer surveillance.
