Introduction
Honeywell Security and Custom Electronics offers Optiflex, a six-camera video controller. The
primary function of Optiflex is to digitize video input (from cameras) and send video in digital
format to Optiflex clients using a LAN, Internet or directly to NTSC monitor. Optiflex provides
local viewing of the cameras from NTSC output, from a local PC using Optiflex Direct software
application, or with Symphony (8132/8132i) touch screen interface. Secure remote viewing may be
accomplished by using Optiflex Connect web-based application that utilizes the AlarmNet
Network Control Center to provide the necessary infrastructure
Hardware Required
Optiflex Hardware
Optiflex is a server device designed to process up to six cameras. The digitized video is sent to LAN
clients (example, Symphony or PC application) and to NTSC video monitor.
Optiflex expects a DHCP server to be running on the LAN segment to which it is attached.
However, the unit can also work with the IP address statically assigned.
NTSC Standalone Mode
Optiflex can work in “standalone mode” – in this mode the unit is connected to cameras and an
NTSC monitor. The NTSC programming is performed easily via 8-position dip-switch. NTSC
programming allows for the following viewing modes: selecting any camera (1-6) or viewing all
detected cameras in the tour mode. Tour mode can be further tuned by selecting desired camera
dwelling time. In this mode Optiflex switches from one camera to another continuously – camera
switches are spaced based on the programmed dwell time.
Optiflex Client Support
When Optiflex is connected to a LAN it sends the digital video in the following formats:
1. For Symphony (8132/8132i) video frame is color space converted to RGB332. The frame
resolution is 320 by 240 pixels or in Symphony quad-camera view 160 by 120 pixels.
2. For PC software– video is sent as discrete JPEG frames. The frame resolution is 352 by 240
pixels.
For the above video formats Optiflex sends discrete frames at the rate of 4 frames per second. The
actual frame rate depends on the following factors:
1. The number of concurrent Optiflex clients connected to Optiflex – the more clients the less
frame rate.
2. The frame size – only JPEG compression – the larger the compressed frame size the less
frame rate.
Mini Video Recorder Mode
Optiflex also works as mini video recorder. The unit continually switches throughout the detected
cameras and acquires a single video frame from all cameras. The frames are collected at the rate of
1 frame per second from each installed and detected camera. The frames are accumulated in the
circular buffer that can hold up to 10 frames. It means that Optiflex can “record” up to 10 seconds
of video from each camera.
However, new frames will overwrite video frames unless the sequence of 10 frames from a given
camera is saved to Optiflex flash memory. Saving to flash memory is performed via external
trigger.
Optiflex can be connected to Honeywell security panels via ECP data bus. When Optiflex is
connected to the panel it works in 4204 relay emulation mode allowing programmable events to
trigger video capture. The panel can associate relay commands and trigger Optiflex to save a
video clip to its flash memory. Optiflex allows up to nineteen 10-frame sequences to be saved
before new clips overwrite them. Saved clips are viewed via a PC using Optiflex Direct or Optiflex
Connect.
Additional Optiflex Features
Optiflex video unit can be remotely upgraded to the newest firmware as long as Optiflex has access
to Internet.
Optiflex is fully multitasking – it can serve multiple LAN clients - up to 2 concurrent TCP
connections, up to 20 UDP unicast connections, NTSC video, concurrently run with video clip
saving or playing back previously saved clip – all run at the same time.
Optiflex System Setup
Optional Hardware
Symphony 8132/8132i
Optiflex is capable of generating the compatible video for the Symphony touch screen interface.
Video frames are sent from Optiflex to Symphony over Ethernet LAN. No special setup is needed
for Symphony to work with Optiflex, provided both are on the same LAN segment and use DHCP
server for IP assignment.
Images sent to Symphony are specifically formatted so the only Symphony can use them – the
color conversion from native Optiflex format to RGB332 is required.
In short, Optiflex sends a series of bitmaps that can be displayed using minimal Symphony
resources.
Symphony can display 2 video frame sizes: full screen (resolution 320 by 240 pixels) and while in
quad view it can display up to 4 video frames which are scaled down to 160 by 120 pixels.
The commands to start particular video stream are sent from Symphony via LAN connections.
Optiflex and Symphony communicate over UDP unicast and broadcast. They use port 1000010010.
There can be multiple Symphony’s on a given LAN segment, all receiving video from the different
cameras at the same time.
Any Symphony can be upgraded remotely to support video feature.
PC Optiflex Client
Optiflex can interface with a PC client using Optiflex Direct software. Optiflex Direct connects to
Optiflex using UDP unicast/broadcast protocols. Optiflex Direct and Optiflex use IP ports 1000010010 to exchange information.
Optiflex Direct receives video in the form of JPEG frames. It can request multiple, concurrent
video streams from Optiflex (up to 6 video streams). In addition, Optiflex Direct is designed to
retrieve and play previously saved clips (video sequences saved to Optiflex flash memory). The
software has the ability to archive all or selected video clips. Archiving of clips is simply a process
of copying the video sequences on to PC’s hard disk. There can be up to 500 video clips archived on
the PC.
Optiflex Connect
Optiflex can also interface remotely using Optiflex Connect. Optiflex Connect requires a Symphony
account. Optiflex Connect is a downloadable application designed as a Microsoft Internet Explorer
plugin – ActiveX.
Download and installation of Optiflex Connect is seamless to the end user.
Once download and install is complete, the ActiveX will be launched from Internet Explorer. The
download and install of the application is possible only after creating a Symphony account. Please
see Symphony manual for details on how to setup an account.
Optiflex Connect communicates to Optiflex using a TCP connection over port 80 – the multiple
secure network links are created to provide maximum privacy and security. The data link to our
video server is encrypted by Blowfish block cipher and Internet connectivity to the server is
secured by SSL (standard – Secure Socket Layer). Blowfish block cipher encrypts the video data
with 448-bit key assigned during the video session handshake. Each new video session uses a
different key.
The above design provides plug and play installations. There is no firewall setup required. Optiflex
and Optiflex Connect, both implement the network client applications – no network server sockets
are created or required.
