At present, roughly 90% of the market for video-transmission services is subject to the constraints of narrow bandwidth. SerVision has developed the most advanced technologies available for handling video in this environment. Innovative compression techniques make it possible to transmit very high-quality video recordings over narrow bandwidths, enabling remote users to view video streams in real-time by PC, mobile phone, or PDA, and significantly increasing the transmission capacities of DVRs.
Even locations that are not connected to the power grid or to wired communications networks can be secured using SerVision equipment. Battery-powered units that communicate with control centers via the cellular network can be installed in vehicles or at remote field locations. SerVision’s compression techniques make it possible to transmit a high-quality video stream from these devices over the narrowband cellular network. As a result, observers in control rooms can monitor events in remote places as they occur, and backup devices located at control centers can record the video streams for later review.
All three sectors of the market for surveillance equipment – commercial, retail, and transportation – can find highly effective solutions in SerVision’s line of state-of-the-art DVR systems. All systems offer a complete array of features, including:
- Real-time video transmission
- Recording of video streams for later playback
- Real-time handling of events such as motion detection or sensor activation, including alarms, notifications, and automatic recording of video footage of the scene for as long as the event continues
- Support for wireless communication via the cellular network or WiFi
- Remote camera control
- Remote device activation
Systems geared to large businesses and large-scale projects contain four to sixteen camera channels, while units that are optimized for home-owners and small businesses have between one and four camera channels. Mobile systems are specially designed to meet the needs of the transportation sector. They contain four camera channels and include the following features:
- Real-time video transmission via the cellular network
- Sending of alarms and automatic activation of video transmission when a vehicle is in danger
- GPS for tracking vehicle location
- Wireless downloading of data via 3G, GPRS, CDMA, or WiFi
The mobile DVR system developed by SerVision has won top honors at four major international exhibitions of surveillance equipment. It has been successfully deployed in many types of vehicles, including trains, trucks, and taxis, and is used extensively by police for mobile surveillance.
SerVision’s technology belongs to the high-end of the surveillance-equipment market, incorporating intelligent video motion detection (VMD) and featuring long-distance recording with RAID 5 disk drives for fast and reliable backing up of data. The technology also includes a sophisticated network video recording (NVR) system, which can be used to automate the downloading and recording of back-up data in control rooms.
Alongside its ground-breaking DVR technologies, SerVision has developed a suite of complementary products, including:
- SVNVR for off-site data back-up
- SVDistributor for broadcasting live video to multiple clients simultaneously
- SVProxy for managing data transmission between wireless SerVision servers and client devices that connect to them via the internet
These products reflect SerVision’s commitment to offering customers complete solutions for their clients’ video security requirements. SerVision prides itself on being a solution provider and not just a product supplier. Many companies in the closed-circuit television (CCTV) sector focus on developing a specific type of device or application, but do not necessarily provide customers with complete setups that meet their needs. Customers may have to purchase other equipment or software to make full use of the products they purchase from these suppliers. SerVision aims to produce a full range of products so that customers can purchase a complete set of compatible security products. To achieve this, SerVision has placed extra emphasis on research and development. While this focus entails additional capital investment, it makes SerVision particularly attractive to large corporate customers and, ultimately, makes SerVision a more profitable company with a very promising future.
State-of-the-art compression and transmission technologies make it possible for SerVision DVR products to transmit high-quality video via the internet to PCs and other devices and via the cellular network to PCs, mobile phones, and PDAs. These technologies have enabled SerVision to develop superior DVR systems, including the best on-line mobile DVRs on the market. Focusing on the needs of its customers has led the company to develop a full complement of hardware and software products that can be used in conjunction with its DVR line. These products complete the SerVision range, so that customers can come to a single address to purchase a comprehensive security system that is well-suited to their needs.
