DVR Security System Review

The Axis 241s is a solution for anyone who has analog security cameras they wish to integrate into a digital surveillance system. The Axis 241s prevents analog cameras from becoming redundant by converting their analog output into digital format. The video server uses both MPEG-4 and motion JPEG video compression and can record video at resolutions up to 704*480 in NTSC mode, PAL offers the slightly higher resolution of 704*576.

You can only attach one analog surveillance camera to the Axis 241s, other models of the video server can accommodate additional cameras. The maximum frame rate for recording video footage is 30 frames per second for NTSC, the frame rate lowers to 25 when recording in PAL. Motion detection is built in to the 241s and the video server also has an alarm notification feature that informs you when external alarms attached to the device are activated.

The internal hardware of the Axis 241s consists of an ETRAX 100LX processor, 32 MB of RAM and there is also 8 MB of flash memory. Your analog camera is connected to the device through its BNC input and the video server also has a BNC output. External alarms are connected to the video server through its four alarm inputs and it has four alarm outputs. The video server also has RS-485/422 ports and it supports security cameras that have pan, tilt and zoom functions.

Connecting your analogue cameras to the Axis 241s gives you the ability to view their output on a PC. The device includes software on CD that you can install on PC’s so you can use it as a means for monitoring your surveillance cameras. Your PC needs to have at least a 500 MHz processor and 128 MB of RAM in order to run the video server software. A mounting bracket and connector kit also comes with the video server and it includes instructions on getting the device up and running.
