## Summary description

Passive surge protection device EWIMAR HDO-1F-PRO designed for video surveillance interfaces AHD, HD‑CVI and HD‑TVI. Provides lightning/surge arresting for single coax/line connections without active electronics, reducing risk of damage to cameras and recorders. Ideal for outdoor and long‑distance camera runs to protect equipment from transient overvoltages.

## Long description

The EWIMAR HDO-1F-PRO is a passive surge protector engineered for analog HD video surveillance interfaces AHD, HD‑CVI and HD‑TVI. It connects inline to a single coaxial camera feed and clamps transient overvoltages caused by lightning strikes or nearby electrical surges without relying on active electronics. The device is intended to reduce the risk of damage to cameras, transmission lines and recorders on outdoor or long-distance runs where exposure to transient pulses is more likely.
Advantages
This passive video lightning arrestor provides surge protection for a single coax line while maintaining signal integrity for AHD, HD‑CVI and HD‑TVI formats. Because it contains no active electronics, it does not require power or introduce additional failure modes, and it reacts to transients quickly to divert excess energy away from connected equipment. Its compact in-line form factor makes it straightforward to install in existing cabling paths and to replace or relocate as needed.
Suitable for
Protection of single coax camera connections in AHD, HD‑CVI and HD‑TVI surveillance systems
Outdoor camera runs exposed to lightning, inductive surges or nearby transient events
Long-distance video links where line-induced surges represent a risk to recorders or cameras
Installations where passive, power-free protection is required
When it may not be suitable
The device is designed for single coax video interfaces and does not offer multi-channel or network-level protection; it may not be appropriate for systems that require protection across multiple lines or integrated Ethernet/PTZ control circuits. It is a passive protector and will not filter noise or actively condition video signals beyond transient clamping.
Key specifications
Compatible video interfaces: AHD, HD‑CVI, HD‑TVI
Protection type: passive surge arrestor for single coaxial line
Connection: inline coaxial connection suitable for camera-to-cable links
Power requirement: none (passive device)
Operation: clamps transient overvoltage events to protect downstream equipment
How to use
Install the EWIMAR HDO-1F-PRO inline on the coaxial feed between the camera and the recorder or distribution point. Ensure connectors are properly tightened and that the protector is positioned where it can be easily accessed for inspection or replacement. No power or configuration is required; the device remains passive and engages automatically when a transient overvoltage occurs. Periodic visual checks are recommended after severe storms or suspected surge events to confirm the protector is intact.
What to consider before purchase
Compatibility with video interface (AHD, HD‑CVI, HD‑TVI) and connector types used in your installation
Number of camera lines to be protected and whether single-line passive protection meets your system requirements
Environmental exposure and whether additional weatherproof housings or enclosures are needed for outdoor placement
Maintenance plan for inspection or replacement after significant surge events
Usage recommendations
For optimal protection, install one passive protector per camera feed at the point where the cable enters the building or at the camera end. Combine with proper grounding practices and, if required by site conditions, additional multi-channel or mains-level surge protection to create a layered defense against lightning and transient overvoltages.
