Wide-Angle Security Cameras – Ultimate guide

Wide angle cameras are easier to achieve total property surveillance coverage. Typically, the larger the area, the more security cameras are needed.

ZOSI advanced camera features a sophisticated super wide angle lens that allows you to monitor a huge area with a single camera. It also has long-range IR night vision capabilities and is fully weatherproof. View more and protect your home or business with this powerful security camera from ZOSI.

Today we offer some helpful tips to choose the best wide-angle security cameras for outdoor and indoor use.

How to Choose Wide-Angle Security Cameras

Security cameras that are capable of capturing up to 80 degrees field of view (FOV) are commonly regarded as wide-angle security cameras. Super wide-angle security cameras could cover up to 180 degrees or higher.

Ultra wide-angle surveillance cameras (CCTV or IP) could boast 360 degrees.

The angle of IP or CCTV cameras or the field of view largely depends on the security cameras’ focal length of the lens and the size of the image sensor.

Focal Length (mm) Diagonal (°) Vertical (°) Horizontal (°)
0 180.0 180.0 180.0
2 169.4 161.1 166.9
12 122.0 90.0 111.1
14 114.2 81.2 102.7
16 107.1 73.9 95.1
20 94.5 61.9 82.4
24 84.1 53.1 73.7
35 63.4 37.8 54.4

Meanwhile, the size of the image sensor and type of image sensor also plays a role in the security camera field of view, for example, a 1/3″ image sensor produces wider viewing angle than that of 1/4″ sensor image sensor.

For example, a surveillance camera with a 1/3″ CMOS sensor and the 4.0mm focal length like ZOSI C306 is capable of capturing 90 degrees field of view horizontally, shown below.

This wide-angle CCTV camera is adequate to monitor the front porch, entryway, hallway, side of the door, alley, side door, driveway, and relatively small areas.

Wide-angle IP cameras with 2mm focal length, in general, cover 166.9 degrees wide areas, like fisheye cameras (panoramic video cameras) with 180/360 degrees wide angle.

Wide-angle surveillance cameras like PTZ IP cameras are commonly seen in large areas like a crossroads, warehouses, parking lots, stadiums, museums, concert halls and etc.

Wide-Angle Security Cameras – What You Don’t Know

Like many other surveillance cameras, a wide-angle IP or CCTV camera has its flaws and benefits, and it always takes a little effort to fully understand them.

1. Wide-Angle Security Cameras: Pros & Cons

It’s true that having a wide-angle security camera helps cover large areas at once, which not only reduces needs to install multiple cameras at one spot but also cuts down installation, maintenance and troubles.

However, among super wide-angle security cameras (IP or CCTV) especially, fisheye or 360 degrees wide-angle cameras, image distortion is a common problem.

Meanwhile, super wide-angle outdoor cameras could sacrifice some details to get wider viewing angles, which makes it harder to identify faces or other small details.

2. Fixed Lens VS Varifocal Lens Security Cameras

Varifocal lens security cameras can adjust the focal length, the angle of view and level of zoom while fixed lens security cameras instead can’t do those.

Therefore, wide-angle surveillance cameras (CCTV or IP) with varifocal lenses do better to zoom out to cover large areas and zoom in to capture small details, for example, this wide-angle outdoor security camera  ZOSI C289.

3. Wide-Angle Security Camera VS Long-Range Security Camera

There is a strong correlation between security cameras’ focal length and viewing range, which is in turn directly linked to the viewing angle of CCTV surveillance cameras.

The longer the camera’s focal lens is, the longer distance it could cover, and vice verse.

Simply put, wide-angle IP cameras are more suitable to monitor objects of shorter distance. For example, IP cameras with 4mm focal length & 1/3″ CMOS sensor (90 degrees viewing angle) like ZOSI C1 are better to monitor areas within 26 feet radius.

Of course, with optical zooming capability, users could zoom in to see small details without compromising video quality.

4. Viewing Angle & Camera Resolution

Interestingly, there is a parameter called PPF (pixels per foot) that has a huge impact on how well your outdoor IP cameras can clearly identify faces or plate numbers.

It’s calculated by camera’s resolution dividing its field of view. And for proper identification of facial and license plate recognition, the minimum measurement should be no less than 40 PPF.

In such sense, the higher resolution your wide-angle IP/CCTV outdoor cameras get, the better identification you could get.

Best IP/CCTV Wide-Angle Security Cameras (Systems) Recommendations

Let’s find out some of the most popular wide-angle security cameras available on the market.

Wide-Angle Outdoor Security Cameras – ZOSI C1

ZOSI C1 Wide-angle wireless security camera is one of the most popular battery-powered wireless outdoor security cameras on the market.
