VDRS Professional OEM is a latest digital recording and video transmission system. VDR-S was designed for professional video surveillance systems with 4, 8 and 16 channels video inputs and could capture up to 30fps (RT version) per each camera.
There are four or eight video inputs on each video capture board. Currently we have three different types of video boards. The first one captures 30fps per four cameras and is used for PRO version, the second one captures 120fps per four or eight cameras and is used for PRO RealTime version.


You can adjust picture parameters separately for each camera. You can set up recording to be permanent, done only on motion detection or on alarm input signal or on scheduled event. Motion detection parameters are adjusted for each camera separately that allows the system to be correctly configured to record the appropriate motion events. This is done to eliminate unwanted motion detection of animals or waving trees. This parameter is especially important because significantly decreases amount of data stored on the hard disk. Motion detection areas could be set up separately in an easy way for each camera by using special mask tool.
VDRS PRO allows you to locally and remotely P/T/Z (Pan/Tilt/Zoom) domes control. You can control domes using the keyboard, mouse or regular USB joystick. You can also record the dome pattern path, program the preset position, etc. We have our own video unique differential streaming compression method developed and used in the VDR-S systems. It allows you up to 90 days of permanent recording from 4 cameras with 6 fps per each camera and average motion intensification on the 60GB hard disk. You can access the video archives and veiw live locally or remotely via any computer network using (internet/streamyx) TPC/IP protocol. Remote access is supported by free of charge client applications VDR-C (currently for PC computers and Handphone ( cellphone ). This type of video surveillance solution allows you remotely view from any part of the world. (Look in a area, before you go in)

VDRS PRO - The surveillance of the distributed structers

The idea of distributed surveillance systems of VDRS digital video recorders could be used in multiple floors structures. Every floor or section of the structure could have one or more recorders installed that are connected to local area network/LAN of the structure. The solution provided will allow you to have a fast and relatively inexpensive surveillance system. Therefore creating a large surveillance system in multiple floor buildings (with the computer network). The access to the recorded archives or live viewing could be provided from any place in the structure. The solution is very useful if you would like to have one or more security stations or you would like to move the security room to another place in the building.
Every recorder located in the building could operate with maximum 16 cameras or domes. The recording could be done locally and/or remotely inside the structure or outside it via Internet. The distributed digital recording system provides you with an additional security for the recorded video that is recorded simultaneously in many places and protects the video archives against the theft or destruction.

Distributed digital video surveillance systems could be commonly used in the medium to large industrial sites, logistic centers, military bases, airports, hospitals, correctional departments, law enforcement agencies, schools, corporate centers, anywhere or anytime the need is for the security of the structures. Every protected structure could have installed one or more digital recorders that can be connected to local area network. In case the area does not have LAN it could be very easily and quickly put in using wireless (802.11b) networks that can cover any area size. Wireless solutions have few additional advantages - the recorded and live video could be accessed anywhere in the covered by 802.11b network area. The security guards patrolling the areas could be equipped with PDAs that would allow them at anytime and anywhere to view (Look in, before you go in) any camera installed in the protected area. This solution could provide you with the effectiveness of your security guards and even reduction of the staff and resources used to protect the area.

Cellphone Client Application

Alnet's VDR-S software uses an industry unique differential compression algorithm. This compression makes VDR-S an optimal video streaming solution for low bandwidth connections like modem dial-up, GPRS or 3G. VDR-S is available for Windows XP only, the VDR-C application is fully compatible with Windows 9x/Me/NT/2000/XP, Pocket PC (PDA) and Symbian and Java used in Nokia, Sony Ericsson mobile phone.
