Osiris offer the following range of components and accessories to increase the power and capabilities of your Osiris DVR system. If you're looking for something in particular and don't see it listed below, please don't hesitate to contact us. If it can be got, we'll do our best to get it for you.

Audio add-on		The hardware audio add-on allows you to monitor and record real-time audio as well as video with your Osiris DVR system. OSR 6xx systems support single-channel audio, while 8xx systems support up to 4 simultaneous channels of audio. Audio may also be played back synchronously with video in order to render a precise replay of the captured event.
Real-time display card		The real-time display card works in conjunction with your Osiris DVR system to allow monitoring of live video from 16 simultaneous cameras at 25 fps PAL each. It also has a TV-out connector, enabling you to route the video feed to a standard TV. (Note, all Osiris DVR appliances come with a TV-out connector as standard. While this can be utilised for standard monitoring, it's capabilities do not stretch to 16 simultaneous live video feeds at 25 fps each.)
Mass storage arrays		If your storage requirements are extremely heavy, you may find yourself exceeding the standard capacity of your Osiris DVR system. While this capacity can usually be increased, it can be more economical to move the storage outside the box. This is especially true where multiple systems are operating in a single location, in which case using a single centralized storage bank can offer significant advantages. Osiris can install and configure storage arrays and, if necessary, the networking infrastruture required to use them, both for use with our own and many other brands of DVR system.
RS-232 to RS-485 interfaces		These interface units provide a low-cost way to connect standard RS-232 equipped devices such as cntroller and alarm units direct to your Osiris DVR system.
Digital sensor I/O		The digital sensor I/O unit is an 8 point digital input & output controller. It provides a direct interface between your external alarm sensors and your Osiris DVR system.
Alarm/PTZ controllers		This controller works in conjunction with a digital sensor I/O unit to provide actual control over your external alarms and PTZ controllers direct from your Osiris DVR system.
UPS and backup systems		If your Osiris system is mission critical, why not let us provide you with the ultimate protection against system or power failure. UPS (Uninterruptible Power Supply) units are basically external power units that allow your Osiris DVR to keep functioning for a time in the event of mains power failure. Backup devices maintain copies of your critical video footage, or even your entire system. This not only provides you with insurance against a storage failure within your DVR system, but can allow you to get up and running again in no time in the unlikely event of a total system failure.
