The Reolink E Series E540 is a powerful 5 MP surveillance camera that, in addition to the proven PTZ function, also has people and vehicle detection, built-in floodlight and siren, WHICH significantly increases protection. Thanks to the floodlight, the E-Series E540 delivers 5 MP colour images even at night (up to 12 m). For objects that are further away, you have the option (3x optical zoom) to zoom in on them via the Reolink APP / client. Thanks to the PTZ function with a 355° pan and 50° tilt angle, the E-Series E540 also allows you to monitor large areas. The camera can be rotated, tilted and zoomed so that every angle can be captured. The surveillance camera can also recognise people or vehicles in its field of view and track them automatically. Note: The function only allows the person/vehicle to be tracked in a horizontal direction. The built-in spotlight and siren are activated by motion detection or manually controlled via the Reolink app to warn unwanted guests. Once the camera detects motion, an alert message will be sent to you in real time via the APP or email.
