## 1 Introduction
Their system allows continuous monitoring of the feeding, drinking, and movement of animals with a high temporal and spatial resolution. [PERSON] [7] developed a non-intrusive cage monitoring system based on electrical capacitance sensing technology. The system can provide 24/7 animal activity metrics including distance walked, average speed, activation density, and occupancy directly from the home cage while keeping the cages in conventional racks, eliminating the need for dedicated personnel or labs. [PERSON] et al. [8] introduced a high throughput system for behavior recognition and motion tracking of rats and mice. However, their system needs the home cage to be placed on top of its motion-sensing table to determine the animal's behavioral data. Their technology is based on measuring the forces induced by the animal's movement and uses pattern recognition algorithms to translate the measured forces into understandable behaviors and tracking parameters. [PERSON] et al. [9] introduced a cage-monitoring system based on using pyroelectric or passive infrared sensors. Their system can be used for phenotypical measurement of circadian rhythms and sleep in laboratory mice. [PERSON] et al. [10] proposed a non-invasive approach utilizing piezoelectric films for rodent sleep and motion detection. In their proposed system, piezoelectric film strips are placed on the floor of the cage which produce electrical outputs proportional to the distortion of the strips. As they postulated, the predominant body movement during sleep was associated with breathing, while other motor activities played more important roles while awake. They also developed a pattern recognition system to identify periods of sleep and waking based on analyzing the generated signals. [PERSON] et al. [11] introduced a simplified microwave-based motion detector system to be used for home cage activity monitoring. In their system, the wave generator is located next to the mouse cage and emits electromagnetic waves to the mouse cage. The reflected waves with modulated frequencies are then sent to the processing unit to detect and save the history of the mouse motion. [PERSON] [12] developed a system based on the RFID detection method which incorporated an RFID tag to the animal's body at the food accessing place. This system was able to monitor each individual animal in a group-housed cage with a high temporal resolution. Most of the available solutions for food control and cage monitoring are either too expensive to incorporate into laboratory equipment or lack the flexibility to be incorporated within existing cages. In many cases, they require an alteration in the current structure of the entire cage and laboratory facility. Furthermore, some of the existing methodologies such as electromyography (EMG), electroencephalography (EEG), and radio frequency identification (RFID) are invasive methods and are not ideal for high-throughput screening [13]. Consequently, food control and activity monitoring for animals in biomedical research labs is usually performed by trained technicians and can be both inconvenient and labor-intensive. In the current article, we introduce a technology named CageView, through which food control and activity monitoring of rodents can be accomplished using an automated, AI-enabled, programmable, and remotely controllable system. This system enables the experimenters to conduct their experiments with greater convenience and increased capacity.
