The Catalyst

Packed with advanced features, digital recorders make for endless possibilities.

By providing a universal interface, RemoteView eliminates cumbersome and costly training. Also, due to its universal interface, RemoteView operates with each and every enterprise-class system manufactured since 1998, and allows users to communicate with any of the company’s security systems.

Additionally, users may control the amount of bandwidth used to transmit information over a network connection with the data rate throttling feature, giving greater control of the system. To make data as portable and easy to store as possible, RemoteView exports video in XPV, and self-extracting EXE file formats, as well as still images in bitmap or JPEG format.

Another example is the VDR-204 from Vicon. It is ideal for your customers who require an easy to use standalone 4-channel digital video recorder with the benefit of additional remote PC access via a network/Internet. The VDR-204 is designed for use with industry standard composite video output CCTV cameras using BNC connectors. Two models are available. The VDR-204-12CD has a 120 GB hard drive; VDR-204-30CD provides 300 GB of hard drive space. Both models are NTSC/PAL compatible.

The VDR-204 is operated and controlled by simple front panel controls. All video recording takes place on the VDR-204 hard disk drive. Backup can be to a CD, through the network using the provided VDR software, or from the USB port to a memory stick. Multiple VDR-204s can be cascaded for greater camera coverage.

The VDR-204 can accept up to 4 composite video inputs with 4-channel loop through to be recorded on a local hard drive. The VDR-204 offers 720 x 480 resolution for a full image and 360 x 240 in Quad view. In addition, the VDR-204 has one audio input, 4 sensor inputs and 1 alarm output. The recorder allows displaying and recording a multiplexed image of the 4 inputs on the same screen at 30 fps, allowing 4 cameras simultaneously at 30 fps each. The unit supports dynamic IP allocation and remote live viewing across common networks.

Product Innovations
Video and the bandwidth it takes up can cause major headaches in an IT department. However, innovations in technology are changing that. Dedicated Micros shows off its hard work in this area with the DV-IP. This unit comes with a MPEG4 feature which provides streaming video while cutting the bandwidth usage by about one-third of the normal amount of bandwidth that is required for 24/7 viewing over the network.

The technology shrinks each digital image by changing the compression to create smaller files that use less space on the network. Fully flexible, users can independently configure the DV-IP Server’s transmission image resolution, bit rate and picture update rate so the DV-IP will not slow down worker productivity on the intranet, or the network itself.

Additional features on the DV-IP Server with MPEG4 include a spot monitor output to provide a visual deterrent that indicates a CCTV system is in place, tamper alarms and an improved audio setting. The improved audio setting allows the installer to set the audio quality to best support the specific application. The default sampling frequency is set to 8KHz, but it can be enhanced to CD-quality to meet higher audio recording requirements.

INTELLEX IP (Internet Protocol) from American Dynamics is also packed with innovation. INTELLEX IP is an enhanced digital video management system that provides support for IP based video surveillance devices, as well as double the frame capacity and twice the resolution of the current INTELLEX system. INTELLEX IP uses video servers and digital video cameras transmitting video over an IP network instead of analog cameras over coaxial cables. Additionally analog cameras can easily be incorporated into an Intellex IP system by using a video server that converts the analog signal to a digital signal.

Intellex IP—which is just one-quarter the chassis size of the previous Intellex system—provides several key benefits, including reduced cabling costs, widespread camera distribution across a wide campus, and greater flexibility to scale to large, high-performance video surveillance systems.

By using a combination of wireless and wired IP technology, customers are able to look at a widely dispersed area and monitor events from a single source.
