Security Cameras

Standalone security cameras for situations where you are adding a position to an existing system or covering a single specific point rather than building out a whole site.
Match the camera to the job. Identification at an entry door needs a narrow field of view at face height — roughly two metres, angled slightly down, and close enough that a face fills a useful part of the frame. Area awareness across a yard needs the opposite: a wide field and enough sensor resolution that the wide view still resolves detail. One camera cannot do both well, which is why single-camera installations so often disappoint.
Light is the deciding factor. Most disappointing footage is a lighting problem, not a camera problem. Check whether the camera has true infrared illumination or relies on ambient light, and watch for backlighting — a camera pointed at a glass door in daylight records a silhouette and nothing else.
Before you mount it. Confirm it is compatible with your recorder or app, confirm the mount suits the surface, and confirm the cable route. Then test the view from the exact position before you drill, using a phone held where the camera will sit. That five-minute check saves most re-installations.
For covert requirements see hidden cameras; for complete installations see camera and DVR sets.
