Surveillance cameras from the famous Hikvision company. The set includes two main types of cameras: 1. Outdoor Bullet Cameras The image shows 3 cameras of this type (rectangular in black and white), specifically designed for open and outdoor spaces. • Key general specifications for this category [1, 2, 17]: • Weather Resistance: They come with water and dust resistance standards (usually IP67), making them capable of withstanding rain, dust, and high temperatures. • Night Vision: Equipped with infrared (IR) illuminators for clear night imaging in complete darkness, typically up to 30 meters. • Wide-Angle Lens: Often come with fixed lenses of 2.8mm (for wide-angle coverage) or 4mm (for slightly further focus). • Common Imaging Resolution: This design covers multiple models with resolutions ranging from 2 megapixels (1080p) to 4 or 5 megapixels, depending on the exact model written on the back label. 2. Dome Camera One camera of this type appears on the left of the image (the white circular one mounted on a base). • Key general specifications [7, 19]: • Usage: Typically used at entrances, hallways, or protected indoor and outdoor areas. • Design: A circular structure that is difficult for vandals to easily change the camera's direction or damage compared to bullet cameras. • Vision and Lens: Covers wide and excellent viewing angles for nearby spaces and rooms.
