• Hikvision have recently introduced EXIR infrared technology into their network security cameras. The benefits of Exire Technology include: (1) Objects will appear more evenly illuminated than in conventional cameras. This will ensure there is light on the edges of the frame and not just in the centre, (2) the EXIR technology allows for a 30% increase in illumination efficiency, which is a much more efficient light source along with enhanced LED light strength, (3)  Hikvision EXIR includes a LED light in the shape of a rectangle that fit’s a normal screen size. This reduces light pollution and improves utilization efficiency.
• Hikvsion Hiwatch THC-B150 is a 5MP  analogue TVI/AHD/CVI/SD bullet camera with 2.8mm  lens and 20m IR range.

• IP66 (durable weatherproof): it is suitable for both indoor and outdoor usage. With IP66 weatherproof rating, it sticks to its position in all kinds of weather including in torrential downpour or a heavy snowstorm and record the most clear and video for you.
• 4 in 1 video output (switchable TVI/AHD/CVI/CVBS)
• Day/Night Switch
• 2.8mm fixed lens
• 40M IR distance
