Technical Specification & Information

This cleverly engineered product can comfortably fit 8 internal hard drives (up to 200gb per drive) for total internal storage of 1.6Tb! Unlike other DVRs using large, noisy fans to cool their HDD, the DVR365 uses intelligent electronics to start and stop the drives when required making the unit as quiet as possible so it can be used in noise sensitive environments. The intelligent electronics also avoid the build up of unwanted internal heat and help prolong the life of the hard drives, a small detail that makes a big difference.

Full Triplex Operation
The DVR365 has full triplex operation. This means that the unit will carry on recording video and audio whilst it is playing back previously recorded data. The DVR365 can also accommodate more than one person connecting to it remotely to retrieve live or recoded data, most other DVRs struggle with just one!


Video Motion Detection
Motion DetectionThere is a video motion detection circuit for every camera input so they all can operate independently of each other. You can select the area of the screen where you wish to look for Video motion by selecting a small square. You could position these squares over a doorway, till, etc so that the DVR picks up movement in these key areas. Although Video Motion Detection (VMD) is a great tool to capture event-only footage, it does have limitations that you must be aware of! As VMD looks for changes in the picture it would see changes in light level as movement. This means cloudy days or moving or flashing lights could falsely trigger the DVR. Similarly at night if the cameras are in very low light and no movement can be seen on a camera's picture nor could the VMD detect movement.

Over The Internet
For real-time video and audio transmission you must have a fast Internet connection at both the DVR’s site and the remote computer site. What do we mean by a fast Internet connection? Well basic broadband (ADSL) is a must. The faster the ADSL connection with an “upload” speed of AT LEAST 250kb/sec this is the minimum requirement to upload video and sound, the faster the connection the better quality sound and video you will receive. If possible we would recommend a 512kb/sec or higher upload speed for best results.

At the remote computer site you will need a “download” speed of at least 250kb/sec or ideally 512kb/sec or more. This speed is a typical ADSL connection.

If you have a standard dial-up connection you can still connect to a DVR365 at a remote site but the DVR365 needs to be set up to send images as “snapshots” obviously not in real-time. As you cannot send audio snapshots over such a connection, audio is not possible.
