The instrumental system assembled consists of video monitors which projects signals from remotely placed video camera in the rat pen with pan and tilt arrangement and all operations are done through control-room. Signals obtained from the camera will pass through the monitor and then fed into VCR system which records the behavioural events. Studies carried out with the above system has revealed that all the characteristic behaviour of gerbils (Meriones hurricane Jerdon) which is significantly superior (P < 0.001) over the direct observation method. The integrated sensing system is an ideal instrumental set up for viewing and recording the behaviour of rodents as well as other animals in the experimental pen throughout the year under varying weather and light conditions.
