Security & Surveillance Solution

Get the camera picture to the control room intact: point-to-point fiber, low bitrate encoding, multi-channel decoding
Fiber carries no current, so induced lightning is not a problem

The hard part is not getting the picture there

It is keeping it running for years across scattered, hostile sites

Four problems that show up on almost every project

  • Scattered points: 100 m of copper is not enough, and coax attenuates faster
  • Add enough cameras and the streams eat storage and bandwidth
  • Mixed generations of gear, and the platform only accepts certain protocols
  • The control room needs a video wall, but decoding capacity runs out

Our approach

  • Point-to-point fiber : uncompressed and immune to interference, the default for long runs
  • H.265 encoding : about half the bitrate of H.264 at equal quality, so storage lasts twice as long
  • Standard protocols : ONVIF, RTSP and RTMP let encoders register with mainstream NVRs and VMS platforms
  • Multi-channel decoding : a 16-channel HDMI decoder or a 16-way platform feeds the wall

Signal Chain

Aggregate at the edge, decode at the center

1 · Cameras Bullet, dome, ANPR cameras
HDMI / SDI / IP
→
2 · Long haul Video optical transceiver or Cat5 extender
up to 10 km single fiber
→
3 · Encoding H.265 multi-channel encoder
4 streams per channel
→
4 · Network Private network, fiber or internet
RTSP / RTMP / ONVIF
→
5 · Control room NVR, VMS, video wall
decode and record

Beyond 100 m from the head end, use an optical transceiver (uncompressed, interference-proof). Only add an encoder at step 3 when the stream has to reach a platform or cross a network.

FAQ

Do you support GB28181 and ONVIF?

Our encoders support ONVIF, RTSP and RTMP, so they register with mainstream NVRs and VMS platforms. GB28181 is a national standard that varies by model - tell us which platform you run and we will confirm before shipping.

How much does H.265 actually save?

As a rule of thumb, about half the bitrate of H.264 at equal quality; real numbers depend on scene complexity and motion. Use that for storage sizing, then verify with a one-week trial on your own cameras.

Is a soft picture a transmission problem?

Not necessarily. Sharpness comes from the camera and lens. Our job is to deliver the picture intact: transceivers are uncompressed, encoders run at the bitrate you set. If the source is soft, no transport will sharpen it.

How many channels per optical transceiver?

It depends on the model: 3G-SDI transceivers are typically 1 or 2 channels, while HDMI models such as the PIS series offer 1/4/8/16 channels. For many cameras, a multi-channel unit saves both fiber and rack space.

Will lightning damage the equipment?

Fiber carries no current, so it does not conduct induced surges - one of the main reasons to choose it over copper for long outdoor runs. Power and grounding still have to follow site practice.
