Video | Audio | Functions | Viewing Software | Hardware | General Video Compression H.263+ Supported Resolutions 4 CIF (704X576) CIF (352x288) Benefits Very high compression ratio. 100:1 compression with very little quality loss. Makes efficient use of storage space. Results in smaller video files for faster transfer times (a concern when trying to pull files off of the hard drive or sharing video clips over email). H.263+ is a proven standard compression algorithm with many industry supporters and commercially available 3rd party video decoders. A PC using a DV capture card will chew through disk space at 14GB/hour (233MB/min). Many DVRs use proprietary compression algorithms (especially those that advertise "wavelet compression"). In comparison, DVD's have a video resolution of 720x480, and VHS tape has a resolution of 352x240.
			Audio Format Linear PCM, 16-bit, 16kHz, mono-channel Benefits No compression allows maximum audio clarity, especially for recording human voice. No compression also saves on CPU usage (thus lower power consumption). Remote Access Remote access to DVR using RTSP/RTP streaming media protocols over IP network connections. Data Channels RS232C for device configuration over a null modem cable. RJ-45 for local playback and control over the Ethernet crossover cable or LAN. Benefits Remote access allows management of multiple DVR’s from a single location. RTSP and RTP are open standard protocols used by many commercial media players. RTSP/RTP is efficient, lightweight protocol with low overhead (important when streaming video over network). Rugged single board design (as opposed to a PC motherboard which requires supporting PCI cards). Reliable embedded real-time operating system for 24/7 operation and fast boot time. Internal temperature monitoring circuit protects DVR from damage due to heat Easy-to-use software compatible with Windows 98/2000/ME/XP Graphical Java client viewing software for connecting over network to DVR for live viewing or retrieval of recorded media. Extracts recorded media from removable hard drive in hot-swap docking bay and archives to central media storage. VCR-like features for operating the unit. Controls in the Java client main window look like VCR controls to make software operation intuitive. Live monitoring and control of DVR both locally (direct connection to the DVR) and remotely (over network). Browse and search through files recorded on removable drive cartridge. Dimensions 6” (width) x 10” (depth) x 3” (height) Compact size allows covert installation in cab or trunk of vehicle. Weight 10 lbs Alarm Inputs 8 NO/NC, 5V TTL Power 12 VDC 30 watts @ 2 amps Very low power consumption. Suitable for mobile environment. In comparison a PC system consumes 200+ watts; non-mobile embedded DVRs consume 75+ watts. Storage 40 GB Removable HD (future versions to have larger drives 60GB, 80GB) HD is key-locked into the DVR chassis to prevent unauthorized access. HD is accessed from the front panel of the DVR allowing HD to be removed without having to open the DVR enclosure. 12 VDC 30 watts @ 2 amps Optional hot-swappable docking bay for removable drive cartridge. Hot-swap is important when collecting media from multiple DVRs. Without it, user would have to reboot PC each time a new drive is connected. Video Input 2 Composite BNC (BNC is a type of locking connector) Accepts standard NTSC signal from any security camera or camcorder. Video Output 1 Composite RCA (standard RCA connector for connecting to TV monitor) Audio Input 1 Mono-channel BNC Audio Output 1 Mono-channel RCA Operating Temperature Storage Temperature 0-70 Degrees Celsius TBD (this will be a larger range than the operating temperature) Serial I/O DB-9 RS 232C 115,200 Baud For the future: connect to serial devices such as PSTN modem or cellular data phone for remote connection when Ethernet unavailable. Network I/O RJ-45 10/100 MBit Ethernet Supports high-speed network connection for live streaming video. In a vehicle installation, the DVR and laptop computer may be connected using an Ethernet crossover cable. The laptop computer then acts as a “remote” viewing station which allows the user to control and monitor what the DVR is doing and to pull recorded data off the DVR while inside the vehicle. DVD-quality video recording. Up to 704x576 pixel resolution. 704 x 576 or higher resolutions are required for clear identification of faces, license plates. Stores 100+ hours of continuous audio and video to a removable drive cartridge. Long recording time eliminates frequent media maintenance (e.g., swapping/rewinding VCR tapes) Supports standalone and networked operation. Standalone allows DVR to be operated without a (network) connection to a computer. Networked operation allows management of multiple DVRs from a single location. Rugged design allows the DVR to be used in harsh environments Sturdy metal enclosure. Locking (BNC) cable connectors to prevent cables from coming loose. DVR suspends operation when temperatures reach unsafe levels. Uses solid-state cooling, no failure-prone mechanical fans. Uses mobile 2.5” drive technology. Supports continuous, time-lapse, and alarm-based recording. Time-lapse for applications which require long-term, constant recording at very low frame rate (1 picture every few seconds) to conserve drive space. Alarm-based for applications where recording is only needed when alarms (siren, panic button, motion sensor) occur. DVR records in a loop overwriting the oldest data on the HD when space runs out. No need to rewind. Pre and post event recording. Pre-event: DVR stores in memory audio/video from the last few minutes, so when an alarm is detected, it can save the audio/video leading up to the alarm. Post-event: It can also be configured to continue recording for several minutes after alarm has passed. Digital encryption technology to ensure tamperproof recording. Guarantees the authenticity of recorded data. Viewing software can detect whether or not a video clip is the original recording. Digital inputs for alarm and sensor connections. These are used for triggering alarm-based recording. Also, the state of each digital input signal is recorded along with the audio/video and appears as a floating text overlay on the video.
