Product positioning
Synesis offershigh performance,ONVIF compliant,
temperature hardened,video analytics devices for
mission critical customers inBorder Security, Transportation
and Energy Infrastructure.
Single channel module• Connect any CCTV or
thermal camera using PAL/NTSC interface
• Output ONVIF video and analytics metadata overFast Ethernet LAN
Dual channel module• Connect two independent
or coaxial cameras using PAL/NTSC interface
• Multiple channel video analytics (combined CCTV or thermal vision systems)
OEM-modules to fit third-party enclosures
Self-contained video analytics device
Dual channel video analytics encoder with
extended ONVIF support
Unique selling positioning (USP)(in comparison with Bosch, UDP and Axis)
1. DSP-based i-LIDS® approved primary detection system both for operational alert use and event recording in sterile zone monitoring applications
2. Supports not only video, but also rule engine, events, metadata, security, and PTZ over ONVIF
3. Extended temperature range (-40..50°C), lightning surge protection, backup battery
4. Available source code and customization options

Sterile Zone Performance38 hours, PAL (720 x 576 x 25 fps), M-JPEG, 40 MbpsNumber of true positive alarms: a = 432
False positives alarms (type I error): b = 0
False negatives alarms (type II error): с = 0

Maximum response time
• People walking and running–2 seconds
• People moving slowly(e.g. crawling)–10 seconds
Causes of false negatives(simple motion detectors)
• Unstable background decreases sensitivity of an adaptive detector
DYNAMIC TEXTURE MODELING ALGORITHMSENABLE ROBUST OBJECT DETECTION IN A CHALENGING ENVIROMENT
Causes of false positives(basic motion detectors)
• Variable lighting– Shadows from moving clouds and sun– Moving trees, bushes and water
• Camera shaking• Animals, birds and insects• Object trajectory split and double detection• Snow, rain, fog
Examples of false positives(simple motion detectors)

Camera connection
• IN – two analogue inputs (BNC connector)• OUT – two analogue outputs (optional)
Back end connections
Dry contacts (1-2, 11-12), power output (3-4), audio input (5-7), audio output (8-9),RS232 (10,19-20), relay (13-16), RS485 (17-18)
Open source ONVIF Device Manager
ONVIF Library Framework and integrated application available for customization and distribution

ONVIF events and metadata
1. Tampering detectors– Video input quality control
2. Object tracker metadata– for server-side analytics and PTZ-targeting
3. Embedded rule engine events– Edge behavior recognition
4. Digital inputs and outputs– Dry contacts opened/closed, relay status
5. Device monitoring– Temperature, power, processor, memory, network
