CCTV Camera Lenses
Small business owners place high priority on employee safety so the choice they make in the investment of a security camera can help ensure that priority is achieved. There are several styles from which to choose and the decision should be based on the particular need and location it will be placed.
The most common types of CCTV cameras and lenses available are:
- The box style camera typically the most frequently used camera in the security industry. These cameras provide myriad choices when making a decision on the lens. The box cameras work with a C/CS style lens mount and this offers flexibility in swapping out different types of lenses to change up the field of view (FOV). The field of view in a security camera is the optimized field of view that the camera can see the total image area that is covered in a particular area and transmitted to the security camera monitors. Individuals can also purchase vari-focal lenses which afford the viewer to change the focal length (or FOV) that encompasses myriad situations. If you’re using a box camera out of doors, it will need to be housed in a weatherproof casing. Box cameras are a perfect option when working in both low light and indoor settings. To enhance the security offered by the camera, you may want to opt for one that offers audio surveillance with built in microphones.
- A bullet security camera is a popular choice on the market. These cameras are built with long tubes equipped with a cylinder-shaped lens which lends to its bullet shape. These cameras are used when discretion in videotaping an area is more crucial than range of view. These cameras are typically equipped with a vari-focal or fixed view camera lens that allows for the ability to capture facial features from as far away as 35 feet. Weather resistant casings are available for bullet style cameras and this makes them fitting for outdoor surveillance especially when facial recognition is important. A high end bullet camera offers options for color images in daylight or black and white images in low light situations.
- Dome security cameras are most frequently thought of when talking about security cameras. These are usually seen in department stores or other public venues. Dome security cameras are favored for indoor settings because of their protected lenses and unobtrusive size and appearance. They are best suited to high light settings and don’t offer the clarity that might be necessary in low light settings.
The only way to determine the best surveillance camera and their placement for your particular needs is to consider the area you will be monitoring, lighting, type of image capture desired and amount of space for mounting. Then by working with a professional, your system can be designed for maximum coverage and efficiency!
