Surge Protector Delta OPV-4S — video surge protector for CCTV and AV lines, 4-channel

Delta OPV-4S is a four-channel video surge protector designed to safeguard CCTV and AV signal lines from transient overvoltages. It is intended for installation on camera feeds, coaxial video runs or at video distribution points to reduce the risk of damage caused by lightning-induced surges or switching transients. The device protects signal integrity while providing a controlled discharge path for excessive voltage between signal conductor and ground.

Advantages

The surge protector offers four independent channels in a single compact unit, enabling protection of multiple video lines with minimal footprint. It is engineered to clamp transient overvoltages and divert surge energy away from sensitive electronics while maintaining low insertion loss and minimal impact on video quality. The design supports straightforward integration into existing CCTV and AV installations and helps prolong the service life of cameras and recording equipment.

Suitable for

• Protection of analog and HD-over-coax CCTV camera signal lines
• Use at video distribution points and junctions in AV systems
• Outdoor camera runs and long coaxial cable runs prone to lightning or switching transients
• Small to medium-sized surveillance systems requiring multi-channel protection

Key specifications

• Number of protected channels: 4
• Type of signal: video (analog and compatible HD-over-coax formats)
• Connection type: inline for video signal lines (compatible with standard coax/video cabling)
• Protection mode: transient voltage suppression between signal conductor and ground
• Form factor: compact multi-channel module for mounting near cameras or distribution equipment

How to use

Install the surge protector inline on each video feed you want to protect, placing it as close as practical to the protected equipment or at the point where the cable enters a protected enclosure. Connect the video input and output in correct orientation and ensure a reliable earth/ground connection to allow surge energy to be diverted safely. Verify signal continuity and video quality after installation. Periodically inspect the device and surrounding cabling for signs of damage or corrosion and replace the unit if it shows visible evidence of surge events or degradation.

Usage recommendations

For best performance, combine the surge protector with proper grounding practices and use it as part of an overall surge protection plan that includes mains and other line protections where applicable. Do not rely on a single device for complete protection in high-risk lightning areas; consider zone-based protection and professional assessment for critical systems.
