Independent UK developer Ben Bird has upgraded his video surveillance system for Mac users, SecuritySpy.

The system offers powerful video surveillance features for Mac users aiming to protect their home or business – motion detection, real-time compression and network video streaming.

SecuritySpy 1.4.1 is a maintenance release for the system, which is capable of displaying and capturing video from multiple cameras (including webcams) at once and which offers wide support for Mac-compatible and network video cameras.

The system also offers a built-in web server for remote viewing and administration, and is capable of uploading captured images to an external server for extra security.

SecuritySpy also offers Pan/Tilt/Zoom (PTZ) support for many network cameras, real-time compression of captured footage, support for QuickTime Streaming Server (QTSS) and can deliver motion-triggered email alerts.

Improvements in the new version include better MPEG-4 compression for remote viewing of live video using a web browser and finer control of compression settings. Support for new models of network cameras also features in this release.

SecuritySpy can be downloaded and tested free of charge for 30 days evaluation period before purchasing, though a demo mode window is overlaid on any video captured.

The software is available at the following prices: Single camera use: $50; Up to four simultaneous cameras: $125; Up to eight simultaneous cameras: $250; Unlimited simultaneous cameras: $500.
