These Best Security Cameras are available in different sizes, shapes, and models depending on the purpose they will be used for. Dome cameras range from small inconspicuous ones to larger weather-resistant PTZ cameras that are capable of moving in different directions and zooming in on an object of interest -Security cameras of this class may be used depending on the area and items to be monitored.
Dome Home Security Systems are the most typical type of security cameras in use these days. These are small security cameras that are shaped in small dome-like structures that contain the camera lens and other components. The dome casing can be given a tinted or smoked look or it can be clear. In their turn, dome cameras are comparatively small, inconspicuous, resistant to vandalism, and quite inexpensive. They are especially suitable for indoor use in residential, commercial, retail, and business premises such as houses, offices, shops, restaurants, etc.
Bullet cameras are so-called because they are of long bullet-like shapes. It has a cylindrical casing that accommodates the camera, the lens, and internal wiring making the gadget easily identifiable. Bullet cameras are easy to install and are most commonly mounted outside of the premise being monitored. This makes them suitable for use in dusty, dirty, and rainy environments as they are protected by their rugged exterior. It encases the camera while also concealing the direction in which it is aimed. Bullet cameras are fitted with fixed focus lenses and may also come with variable focus lenses. The fixed lens allows the camera to have a broader but targeted view and the varifocal lens can be manually moved to increase or decrease the camera's field of view.
PTZ is a type of camera that means pan–tilt–zoom, which can rotate horizontally, tilt, and zoom in with considerable clarity. Since a PTZ camera can capture a large area, it can replace several fixed security cameras and systems. PTZ cameras are usually rectangular where all the motor wiring, computerized controls, and other components are located. The housing is typically made from durable aluminum and strong plastic or stainless steel. These housings help the cameras to be protected from natural conditions and continue functioning in various conditions.
Infrared cameras have unique casings designed to incorporate the infrared LED light strip. They can be an IR bullet camera or an IR dome camera but it’s their black glossy housings that distinguish them from regular security cameras. The black housings help to reduce reflective light that would otherwise wash out the infrared light spectrum, making the cameras ineffective. The dark color is also useful in ensuring that the cameras are concealed for the efficiency and effectiveness of the cameras.
License plate capture cameras are specifically intended for vehicle surveillance, and therefore, they will also appear considerably different from other cameras. They typically use high-definition zoom lenses in rectangular camera housings attached to roads and edges of vehicle traffic and car parking zones. The superior quality camera lens enables one to acquire the level of resolution that will enable the capturing of readable images of license plates on speeding cars.
Night vision cameras are characterized by high-quality light sensors enabling them to capture good quality black and white images in low-light scenes. As for most of the security cameras today, they may have some ability to capture images in low light conditions but night vision-specific cams are still buyable. While they are pretty much like normal cameras during the day, they use active infrared technology to provide the best result in no-light conditions. The camera lens will often be accompanied by IR spotlights which give a source of Infrared illumination to the camera at night.
These body-worn cameras have gained popularity in the recent past for their contribution to the increase in police accountability. Body cams are compact and durable as the device would be worn by a mobile officer for an entire shift. The camera is integrated into the front-facing region of the body cam enclosure; the microphone, battery, and hardware also reside in this region. As additional features, controls such as power buttons and indicators LEDs are also included on the exterior housing that usually snaps on a uniform. Small and light, preferably made of waterproof and impact-resistant plastics, enough ventilation is provided to avoid fogging up during use.
Identity capture cameras are useful to support criminal identities against photographic signatures, identities, and fingerprints. However, instead of observing a scene, they just take high-quality photographs that depict the subject with his or her face towards the camera. These camera settings may include a low-angle close-up camera shot accompanied by bright fill lights to ensure that the subjects are well-lit on both sides. Unlike regular security cameras, identity capture cameras will be placed at an average height of 5-6 feet on the ground on sturdy floor mounts for facial capture.
This is because covert cameras do not want to be seen at all to get candid video clips. Some of the hidden and disguised cameras include clock cameras that are put in the casing of a clock placed above the door leading out of the premises meant for capturing people’s movements in and out. Smoke detector dome cameras shoot videos from room ceilings without being noticed. Mini spy cameras can be hidden in common-use items such as hats, pens, calculators, and even water bottles. The casing of the hidden cameras can be any type of casing imaginable or designed. Spy cameras that are tiny in size can be put through small holes to watch babysitters and caregivers from a different room.
