Our friends from Pipl.ua have created an excellent review of the ready-to-use intercom system kit, Slinex SQ-04M + Slinex ML-16HD.
The undeniable advantage of this equipment is the built-in software motion detection, which captures any movement and saves the data to a memory card. The Slinex SQ-04M intercom features a 4.3-inch high-resolution screen for clear images. Despite its compact body, it includes a built-in power supply. You can connect 2 outdoor panels and 2 cameras.
The Slinex ML-16HD outdoor panel stands out with its 2-megapixel Full HD camera, a wide viewing angle (76˚), and a mechanical IR filter for crisp images even at night.
