Optics & Performance: Features a 3.5~8 mm varifocal lens and a minimum illumination of 0.0 Lux with IR LEDs on. Signal output uses the NTSC system.

The bracket conceals wiring to protect cables from tampering, and the enclosure is weatherproof for outdoor mounting. Connections & Power: Video is transmitted via BNC connector and power uses a 2.1 mm center positive power plug. Each camera draws 12V DC 500mA (power supplies included). Package Contents: 4x Dome Camera, 4x Power Supply, Free Warning Stickers. Important Notice: These are traditional analog cameras (old style); they are not wireless and do not support WiFi. They are not compatible with HD systems and will not operate alone — they must be connected to other equipment such as a traditional analog DVR (Digital Video Recorder), cable and monitor (not included). If you have an older DVR system around 10 years old, these cameras may be used with it. If you are new to surveillance systems, this product is not recommended.
