Product Introduction
GE Interlogix S739DVR-RST1 Fiber Optic Video Receiver
The GE Interlogix S739DVR-RST1 is a rack-mount multimode fiber optic receiver designed for analog video and up-the-coax control data transmission. It receives one video channel over optical fiber while supporting two-way control communication, including response and Genlock signals.
Its primary advantage is combining video and control transmission over one fiber connection. The 800-TV-line resolution specification, transmission distance of up to 18 km, and SMARTS diagnostics make it suitable for geographically distributed surveillance installations.

Application Scenarios & Field Pitfalls
Engineering Pain Point
A remote security camera suddenly loses its video feed at the central monitoring station. The camera itself remains powered, but the control room receives no usable image. Replacing the camera immediately may waste maintenance time because the fault could originate in the optical receiver, fiber connection, or transmitter configuration.
The S739DVR-RST1 provides the receiving end of this transmission path. It is intended for systems that carry video and up-the-coax control information over multimode fiber. Correct transmitter-receiver matching is essential.
Typical Applications
- Power Generation: Remote surveillance of generator halls, substations, and electrical distribution areas.
- Oil & Gas: Video monitoring of remote pipeline facilities, compressor stations, and perimeter security installations.
- Transportation Infrastructure: Centralized camera monitoring across tunnels, transportation facilities, and remote access points.
- Industrial Manufacturing: Optical video transmission between production areas and centralized security control rooms.
Technical Pitfalls to Avoid
1. Receiver and Transmitter Compatibility
The S739DVR-RST1 is a receiver, not a transmitter.
Its corresponding transmission equipment must support the same multimode fiber architecture, video format, and up-the-coax control signaling.
Check the transmitter’s complete model number before ordering. A receiver from the same product family is not automatically compatible with every transmitter variant.
2. Single-Fiber Configuration
This model is specified for one multimode optical fiber.
Do not confuse it with the RST2 version, which is listed as a two-fiber configuration. Check the existing fiber route, optical connectors, and transmitter configuration before replacement.
Also inspect connector cleanliness and optical attenuation. Dirty connectors and damaged fiber can produce intermittent video loss that resembles an electronic module failure.
3. Rack Installation and Signal Verification
The designation identifies the rack-mount configuration.
Before installation, inspect the rack interface, power connections, and module seating. After replacement, verify:
- Video reception and image stability.
- Up-the-coax camera control response.
- Genlock and response signal operation.
- SMARTS diagnostic indications.
- Performance over the actual installed fiber route.
Field recommendation: Do not approve a replacement based solely on the S739 model prefix. Confirm the complete suffix, fiber count, transmission direction, and control-data requirements.

Procurement and Replacement Checklist
Before purchasing the GEo, verify:
- Ed.
- Equipment function: Receiver, not transmitter.
- Fiber type: Multimode.
- Fiber count: Single-fiber configuration.
- Video channel requirement: One channel.
- Control requirement: Up-the-coax two-way data.
- Mounting arrangement: Rack-mounted .
- Transmitter compatibility and optical connector type.
- Functional test results for video, control data, and diagnostics.
Final engineerin is a fiber optic surveillance transmission component, not a PLC or DCS I/O module. For industrial security-system maintenance, matching the optical transmission architecture is more important than matching the manufacturer’s name alone.
