## Summary description

EWIMAR LHD-8R-EXT is a surge protection device designed for video transmission lines compatible with AHD, HD‑CVI and HD‑TVI standards. It incorporates a MOSFET fuse for controlled disconnection during overvoltage events, protecting cameras and recorders from transient surges. Suitable for CCTV installations and outdoor or indoor video links where lightning or surge risk exists.

## Long description

EWIMAR LHD-8R-EXT is a surge protector designed for video transmission lines used in CCTV systems that support AHD, HD‑CVI and HD‑TVI standards. The unit integrates a MOSFET fuse that provides controlled disconnection in the event of an overvoltage, reducing the risk of damage to cameras, recorders and other video equipment. The device is suitable for use in indoor and outdoor video links where transient surges or lightning-induced voltages may occur.
Advantages
The surge protector offers coordinated protection for high-definition analog video lines without introducing significant signal loss or visible degradation. The MOSFET fuse enables rapid and controlled disconnection under excess voltage and restores or remains open according to the device design, helping to prevent permanent damage to connected equipment. The compact form factor allows for installation near cameras, junction boxes or inside enclosures used in CCTV installations.
Suitable for
 Protection of AHD, HD‑CVI and HD‑TVI video lines in CCTV systems
 Indoor and outdoor video cable runs exposed to transient surges or indirect lightning strikes
 Installation near cameras, recorders or at distribution points in surveillance networks
When it may not be suitable
This device is intended specifically for video transmission lines and does not provide comprehensive protection for power supply circuits or data networks. It may not be suitable as the sole protection measure in environments with extremely frequent direct lightning strikes or where a full coordinated surge protection system for power and signal lines is required.
Key specifications
 Supported video standards: AHD, HD‑CVI, HD‑TVI
 Protection type: surge protection for video line with MOSFET fuse
 Application: inline protection for coaxial video transmission
 Mounting: compact unit suitable for near-camera or junction box installation
 Environmental suitability: designed for use in indoor and outdoor video links (install according to enclosure and IP requirements)
How to use
Install the surge protector in series with the video coaxial cable between the camera and the recorder or distribution point. Ensure correct polarity and signal path according to the installation diagram supplied with the device. Mount the unit in a location that provides protection from direct mechanical damage and, if used outdoors, within an appropriate weatherproof enclosure or junction box. Test the video link after installation to confirm proper signal transmission and check that grounding and overall system earthing are correctly implemented for effective surge protection.
What to consider before purchase
 Confirm compatibility with your video standard (AHD, HD‑CVI, HD‑TVI)
 Plan for proper grounding and earthing of the surveillance system
 Decide whether additional surge protection for power and network lines is required
 Consider mounting location and whether a weatherproof enclosure is needed for outdoor installations
Usage recommendations
Use this surge protector as part of a broader protection strategy: pair inline video protection with appropriate power-line surge devices and ensure proper grounding to achieve effective protection against transient surges and indirect lightning effects.
