4 Questions for Choosing the Right Camera
1. What are you trying to monitor?
(Helps determine mm lens type)
a. Close-Proximity/Closed Proximity - If you’re looking to monitor an
area nearby to where the camera will be mounted or a small area
such as a lobby, a camera with a mm (millimeter) level below
4-5mm is needed.
b. In the distance – For monitoring a large area or something in the
distance away from the camera, a camera with mm level above
6-7mm is required.
2. Where is the location of the camera?
a. Indoors – These cameras are smaller, less heavy and less expensive
than outdoor models. However, outdoor models can also be used
indoors.
b. Outdoors – A weatherproof IP66 casing model camera is
required because wind, rain, UV rays and contaminants can all
affect surveillance. Outdoor cameras are also built to withstand
vandal attacks.
3. Will there be bright light or low light?
a. If the video surveillance camera is placed in a bright, well-lit area,
most cameras will have ample light for capturing clear images.
b. In dim lighting conditions, select a camera built for that
application with a light sensitivity rating of 1 Lux or below – it will
either be labeled as a Day and Night camera, or will list low-light c
ompatibility among their specifications. Day/night video cameras
offer most flexibility, as they allow you to consistently monitor a
given space, even if light levels continually fluctuate.
c. In low light or no light conditions, it’s important to invest in an
Infrared camera that can shoot images in darkness.
4. Is the camera ONVIF-compliant?
