DVR Security System Review

Here we have the Sony EVI D70, this Sony security camera has been created to succeed the Sony EVI D30, the camera uses an NTSC video signal and has a compact outer casing.  The security cameras lens has a greater movement range than its predecessor and is unique to the Sony EVI range as it is the only model in their range designed to be mounted on a ceiling.  The Sony Security cameras lens is a ¼ inch Exview HAD charged coupled device and is capable of capturing images in both color and black and white.

The camera uses ‘Sony Visca Commands’ and this basically enables you to control the cameras functions from a PC.  If the graphics card on your PC has an S-Video input this may be all you need to connect the camera, Sony provide software for the camera that is installed on your PC allowing you to turn it into a monitoring station.  If your graphics card does not have an S-Video output you will need to install a DVR card, alternatively you can connect the DV70 to a standard DVR to record its feed.

You can set the camera to use automatic focusing, the optical wide end of the cameras lens has a minimum focal distance of 10 millimetres.  The cameras auto focusing function has a number of preset options, normal focusing is best suited for monitoring subjects that move around frequently, the low auto focusing setting compensates for low level lighting.  The camera has an effective pixel range of 768*494 and has a shutter speed range between 1 and 1/10,000.

In dark conditions the camera automatically shifts to black and white mode enhancing the quality of images, the camera has an 18x optical zoom and a 12x digital zoom the maximum picture resolution of the Sony security camera is 470 TV lines.  The camera requires little maintenance one set up but to avoid an AF error it is recommended that you use the CAM_Initialize command in the cameras user interface daily.

You can control the cameras pan, tilt and zoom functions directly from your PC or through a DVR that includes an appropriate RS-232C port, the cameras gain control can be controlled by the user or you can set this function to automatic.  The Sony security camera also has a Visca RS-422 connector increasing its compatibility with recording devices.
