Hollingsead manufactures the Our Sentry One™ Cockpit Door Video Surveillance System (CDVSS). This system has been selected by eleven (11) airlines and is installed on over 575 aircraft under a wide variety of Supplemental Type Certificates (STCs).
Sentry One™ meets or exceeds the latest EUROCAE ED-123 (WG66) recommendations, FAA memorandum 01-111-196 requirements and is an acceptable method of complying with JAR-OPS 1.1255(c)(2) and proposed FAR 121.313(k) amendment (NPRM). The near infrared cameras are a key element in the surveillance system. The use of a highly sensitive CCD sensor assures visibility in conditions with a minimum illumination of 0.0003 lux (approximately 100 times more sensitive than a standard low light camera). This extreme low light capability provides clear visibility in all normal and emergency aircraft lighting conditions.
The Sentry One™ Camera Control Unit (CCU) provides full crew interface in a pedestal, side panel or overhead mounted ARINC 601 form factor that is approximately 1.1” wide. The CCU has an integral power supply with a design architecture that prevents a single component from causing a system-wide outage. Additional features include manual dimming override, VDU on / off and camera select.
In addition to acceptance by eleven airlines, Embraer installs Sentry One™ on the ERJ-170/190 as an OEM option and Boeing has modified the B777 wiring provisions to support a quick retrofit of the system after customer delivery.
Hollingsead has also developed the Sentry One™ AVS-4 server. The purpose of the AVS-4 server is to integrate the Sentry One™ CDVSS with Electronic Flight Bag (EFB) systems. The server has been developed using a Linux based operating system, running on 32Mb of read only flash memory to avoid corruption by power up / down. It converts the video signal to digital (Ethernet). A small software program installed on the EFB gives the operator the control over the camera system. A recording option is also available.
