As exercise strikes throughout totally different zones, the cameras can robotically coordinate their actions and reframe the shot. This characteristic can be known as Bullet-co-PTZ Monitoring.
The system can be outfitted with a characteristic named Clever Auto-Framing, which can be famous within the product’s listing of key capabilities. With this functionality, the PTZ lenses can lock onto movement. As soon as locked, they robotically zoom in or out with precision to maintain the topic in body. This technique is designed to easily monitor folks or objects at a distance of as much as 50 metres, or 164 ft.
The said objective of this mixed triple-lens {hardware} and AI monitoring software program is to ship versatile protection throughout a property, capturing particulars with out blind spots.
Photo voltaic Energy and {Hardware} Sturdiness

The eufyCam S4 is designed for continuous operation utilizing a built-in photo voltaic charging system.
Photo voltaic Panel Expertise
The digital camera contains a built-in 5.5W photo voltaic panel, which is described by eufy as its largest and best panel to this point. Product info states that this panel can absolutely cost the digital camera for a whole day’s operation with only one hour of direct daylight. This characteristic is recognized in specs as SolarPlus 2.0.
The photo voltaic panel has a removable design, providing versatility for set up. A consumer can select to detach the panel from the digital camera physique and place it individually. This permits the panel to be positioned in a location with optimum solar publicity, even when the digital camera itself is in a shaded space. Alternatively, the panel can stay connected to the digital camera for a cleaner, low-drill setup.
Bodily Building
The photo voltaic panel has been designed for sturdiness in out of doors environments. It contains a distinctive edge-sealed design. This building technique is meant to boost its sturdiness by stopping widespread points akin to warping and effervescent, which may happen with out of doors publicity.
Moreover, the panel is made utilizing ethylene tetrafluoroethylene (ETFE) movie. This materials was chosen for its superior resistance to water, mud, and corrosion. These traits contribute to the long-lasting out of doors efficiency of the photo voltaic charging system.
To make sure the digital camera stays powered even in excessive situations or during times of extended low mild, it’s also outfitted with a quick-swap rechargeable battery.
Detection, Deterrence, and Recording
The eufyCam S4 features a multi-faceted system for detecting movement, deterring intruders, and storing footage.
Twin Movement Detection
The digital camera makes use of a twin movement detection system to establish motion precisely. This technique combines two varieties of know-how: radar and passive infrared (PIR). This twin strategy is designed to precisely establish the motion of people and automobiles. A major advantage of this method is the minimisation of false alerts, which may be triggered by non-relevant movement like falling leaves or small animals. Product specs additionally word that the AI can establish people, automobiles, and pets.
Lively Deterrence Options
When the detection system identifies an intruder approaching the property, the eufyCam S4 prompts a robust deterrence sequence. This contains each visible and auditory warnings.
The visible deterrent consists of purple and blue warning lights. These lights, together with the 5-LED spotlights, activate to attract consideration to the intruder. Concurrently, the digital camera emits a 105dB siren. This mix of flashing lights and a loud siren delivers a robust deterrent sign to discourage trespassers and maintain the house safe.
