Standalone optical transmitter + DOME |
Dome with embedded optical transmitter |
|
Installation |
Need to do layout of power lines, video cables and data cables
Need to install Dome and optical transmitter
More steps for installation and longer installation period |
Only need layout of power lines and fiber
Only need installation of the dome.
Fewer steps for installation and shorter installation period, saving project time |
|
Lightning proof |
Besides the internal function of lightning proof design for dome and optical transmitter, the data lines, video cables and power supply cable exposed are required to do lightning proof to achieve solid performance.
Buying those lightning proof modules adds project costs and period |
Designed by lightning proof technique, only power cables need to do external lightning proof.
No need to buy lightning proof modules for video signal and data signal.
Saving total budget and project time |
|
Water proof |
All electrical cables need to do water proof
Standalone optical transmitter is required to install within a water-proof box. |
Outdoor dome is water-proof design
No need of buying water-proof box for video optical transmitter. |
|
Noise proof |
If the electrical cables are too long (>150meters) or in bad condition, the video would be disturbed and even worse data transmission. |
Connections between camera and optical transmitter are board level. And all parts are built within the dome metal shield to avoid any electromagnetic noise. |
|
System Performance |
The optical transmitter must be installed and non-stop running in a water-proof box under extreme hot, cold or high humidity weather.
System lifetime is cut-off due to the environments factors. |
With embedded fan, heater and drier, both camera and optical transmitter are guaranteed in a better environment to extend device lifetime. |
|
System Maintenance |
As some optical transmission devices do not support network management system, it抯 difficult to diagnose problems except that sending technical engineers to the camera side to do trouble shooting. |
This solution supports remote management system. Any malfunction can be easily positioned at remote side via IP network. Also auto alarm function is supported when system failure.
Easy maintenance, fewer labor required |
