DVR Security System Review

The Axis 240Q is designed to enable the integration of analog security cameras into a digital surveillance system.  The blade versions of the Axis video servers are designed for large scale surveillance system installations, they are fitted to the Axis rack which neatly houses a number of the devices.  The 240Q will accommodate up to four surveillance cameras and has 4 BNC inputs, the device works by converting the analog signal from your cameras into a digital signal.

As far as frame rate is concerned the 240Q has lower capabilities than the majority of its counterpoarts in the Axis video server range.  At maximum the device delivers video at 6 frames per second per channel, this recording speed may be adequate if you need to monitor an area with lots of activity while avoiding overuse of video storage space.  The video server uses motion JPEG compression and can display video at resolutions up to 704*480 in NTSC mode and 704*576 in PAL mode.

You can select one of eleven preset levels of video compression with the device and you adjust its network bandwidth usage.  The image output of the video server can be adjusted in numerous ways, the device has the ability to rotate images and you can switch between color and black and white mode.  Cameras attached to the device can be labelled with a specific name that will be displayed when monitoring the output.  This feature helps you to quickly identify cameras attached to the system but you can replace the name with the time or a specific image if preferred.

Video recording can be triggered through the device with the use of external alarms, the video server is fitted with four alarm inputs and will activate recording should it detect an alarm is activated.  Recording can also be triggered through means of motion detection or you can set a schedule that determines recording times.  The video server is fitted with an RS-485/422 port and a D-Sub for an RS232 port and its supports cameras with PTZ functions.

The video server can stream video footage captured over computer networks and it comes with software compatible with Windows that enables you to set up PC’s as monitoring stations.  An Etrax 100LX CPU is built in to the 240Q and it has 32MB of memory and a supplementary 8MB of flash RAM.
