Security Camera Cables, Connectors & Video Storage
Shop Cat5e and Cat6 Ethernet cables for IP and PoE cameras, coax cables and BNC connectors for CCTV systems, and 2TB–20TB Seagate surveillance hard drives for compatible NVRs and DVRs. Match your wiring and storage to your equipment, recording schedule and video-retention needs.
Security Camera Cables, Connectors and Video Storage
A professional surveillance system depends on more than cameras and a recorder. The correct security camera cables, connectors, power accessories and video storage help provide stable communication, dependable power delivery and useful recording retention. This category supports wired IP and PoE camera installations as well as HD-over-coax CCTV systems.
Choose cabling according to the camera and recorder technology—not only the required length. PoE IP cameras commonly use Cat5e or Cat6 Ethernet cable, while HD CCTV cameras use compatible coaxial cable with BNC connections and a power path. NVRs and DVRs also require appropriately sized surveillance hard drives for local recording.
Choose the Correct Cable for Your Camera Technology
Cat5e and Cat6 Cable for PoE IP Cameras
Compatible PoE security cameras use Ethernet cable to carry electrical power and network data between the camera and a PoE-enabled NVR or switch. Premade RJ45 cables can simplify shorter installations, while bulk Cat5e or Cat6 cable allows custom runs when properly terminated and tested. The camera, recorder, switch, cable distance and PoE requirements must be considered together.
RG59 Siamese Coax Cable for CCTV Cameras
Siamese security camera cable combines a coaxial video path with a separate power pair in one joined cable. It is commonly used with compatible HD-over-coax CCTV cameras and DVRs. BNC connectors terminate the video side, while supported power connectors complete the power connection. Existing coax may sometimes be reused, but cable condition, type, distance and connector quality should be checked first.

Security Camera Connectors and Installation Accessories
RJ45 Connectors and Ethernet Tools
Bulk Ethernet cable must be terminated consistently with suitable RJ45 connectors and a compatible crimping tool. A cable tester should be used before a camera is permanently mounted. Poor termination can produce intermittent video, network errors or power problems that resemble camera failure. Protect outdoor and exposed Ethernet connections inside compatible junction boxes rather than leaving plugs open to moisture.
BNC Connectors, Couplers and Power Adapters
HD-over-coax installations may use compression or twist-on BNC connectors, BNC couplers, power pigtails and other adapters according to the wiring design. The connector must match the cable type and should be installed securely to preserve the signal. Avoid unnecessary couplers and poorly protected joins because every connection point can become a source of signal loss or intermittent operation.
HDMI Cables and Local Monitor Connections
An HDMI cable commonly connects an NVR or DVR to a local display for setup, live viewing and playback. Select a cable length and display connection supported by the recorder. For longer or specialized display runs, verify the complete connection method before installation rather than assuming a standard short HDMI cable can be extended indefinitely.
Converters and Baluns
Baluns and converters can solve specific wiring or display challenges, but they do not make every camera, cable and recorder interchangeable. Confirm the input format, output format, supported resolution, power requirements and distance before using an adapter. A purpose-built compatible connection is preferable to stacking several converters together.
Video Storage for NVR and DVR Recording
Surveillance hard drives are designed for continuous video-recording workloads. Storage requirements depend on camera count, resolution, frame rate, compression, motion activity, recording schedule and the number of days footage should remain available. A larger hard drive does not improve image quality; it extends retention when the other settings remain the same.
Plan storage using the completed system rather than only the cameras installed on the first day. Adding cameras later increases the amount of recorded data and can shorten the retention period. After setup, confirm the recorder is writing video correctly and check how many days of footage are actually available under normal activity.
When local storage becomes full, many recorders can overwrite the oldest video so recording continues. Important footage should be exported before it is overwritten. Browse all security camera recorders or contact the support team for help estimating retention.
Plan a Reliable Security Camera Cable Installation
1. Match the cable to the system
Identify whether each camera is IP/PoE or HD-over-coax CCTV and confirm the recorder technology. Do not choose cable solely because a connector appears to fit.
2. Measure every cable route
Measure the real path around walls, ceilings and structural obstacles—not the straight-line distance. Leave a reasonable service loop without creating unnecessary coils or exceeding supported distances.
3. Protect connections and follow cable ratings
Use cable appropriate for the installation environment and protect exterior connections from moisture. Follow applicable building and low-voltage requirements, and use a qualified local installer when cable routing or elevated work is outside your experience.
4. Label and test before finishing
Label both ends of every run, test the cable, verify power and video and confirm the intended camera name at the recorder. Testing before walls or ceilings are closed makes troubleshooting much easier.
