You work hard to keep your home and office safe and looking good, but robbery or vandalism can shatter an owner’s confidence in even the nicest-looking place. A security camera is your best bet as a property owner to protect the things you work hard for. They deter criminals before the act is committed, and record them if they still go through with it!

Learn more about the different types of cameras, below.

Not just for banks anymore…

Surveillance cameras are being used in retail stores, schools, hotels, nurseries, hospitals, private homes, and more. Isn’t it time you start protecting your home and office, too?

What makes a security camera?

Security cameras, also known as CCTV cameras, use CMOS (complementary metal-oxide-semiconductor) or CCD (charge-coupled device) video chips to capture high-quality surveillance video, similar to a point and click camera. The larger the chip size, the better the image. CCD chips come in 1/4, 1/3 and 1/2 inches, with 1/3 being the most commonly used.

Which one do I choose?

Choose the camera that best suits your needs from a range of form factors and functionalities, including wireless, dome, and/or infrared. Keep in mind the location and lighting of the area where you are placing the camera for the best results. More details about the different types of security cameras is below.

Black & White

Black and white CCTV cameras offer high resolution, and are ideal for home use. They do not capture color video, but in many situations color is not required.

Infrared

Infrared cameras can switch from color to grayscale depending on lighting conditions. At night, they capture black and white footage due to the infrared, but during the day they capture color.

Weatherproof / Vandal proof

If you’re placing your camera outside, make sure it’s a weatherproof and/or vandal resistant version. They are made to be both compact and rugged for outdoor use, but many cameras made today are effective in just about any environment.

PTZ (Pan-Tilt-Zoom)

Cameras that zoom, pan 360 degrees, and tilt are known as PTZ cameras. These cameras can often perform double duty, as they can cover a much larger area. Some software even allows PTZ cameras to follow moving objects, making them ideal for police departments and other government agencies.

Fisheye

If you have a large area that you want to cover with one camera, consider the fisheye option. Fisheye surveillance cameras have a wide angle 360º lens that is perfect for monitoring your company’s sales floor, cash registers, etc. The software for fisheye cameras also allows you to zoom in on and zone off specific areas to watch individually, as if you had multiple cameras in one.

Dome

Dome security cameras, like the kind you see in malls or banks, are covered with a small, dark dome that allows the camera to see out, but makes it very hard for a person to see in and judge where the camera is pointing.

Box

Box cameras are your traditional camera that you see in many public places. They are typically mounted on a mounting bracket and sticking out from a wall with wires connected. These cameras are typically larger than dome and cube camera, but usually offer higher resolution, interchangeable lenses, and better construction.


Cube

Cube cameras are relatively new in the CCTV world and are thinner, front to back, than a traditional box camera, but are taller top to bottom and left to right. This allows them to have a lower profile and not stick out so far from the wall when mounted. Most cube style security cameras have options for night vision, and some are network-based, as well. 

Network (IP) Cameras

If you need to share your footage across a system, want higher resolution options, and need more access to your security system, network CCTV cameras are available that allow the user to monitor the feed from anywhere with internet access. IP cameras can also use power-over-ethernet (POE), which removes the need for a power supply for every camera. These cameras are typically higher resolution, as well, allowing for an overall higher quality recording.


Wireless

Wireless cameras can also be considered IP cameras, but they do not require ethernet to connect each camera to the network. They do, however, require power. These cameras are becoming more popular and reliable as technology improves. Wireless security cameras are ideal if running cable is not cost effective or possible. We have integrated systems that transmit wireless video up to two miles. 

Mini / Covert / Spy /hidden Cameras

Looking for something a little more… discrete? Consider a hidden camera, also known as mini, or covert. These cameras come in the shape of motion detectors, fire alarms, screw heads, fire sprinkler heads, and more.

We understand that your needs are unique, and we’re committed to offering the best solution for your security. Whether your situation calls for a covert spy camera, a complex wireless system, or a trusted, everyday box camera, we’re here to help you find your best option.

What is Onvif Protocol?

ONVIF is committed through a global open interface standards to promote the network video applications in the security market, the interface standard will ensure that different manufacturers compatible between network video products.

In May 2008, jointly by Axis, Bosch and Sony announced three parties will work together to establish an international open standard network interface of network video product development forum, named ONVIF (Open Network Video Interface Forum, an open network video Interface Forum), and open and common development of open industry standards.

onvif

The function of Onvif protocol

Onvif protocol describes video mode network models, interfaces, data types and data interaction. And reuse some of the existing standards, such as WS series standards. The goal’s of ONVIF protocol is to achieve a framework agreement online video, produced by different vendors of network video products (including front-end cameras, video equipment, etc.) is fully compatible.

onvif

ONVIF protocol forms part of the management and control of equipment as defined are all provided by Web Services interfaces. The definition of ONVIF protocol covers the complete definition of XML and WSDL. Each terminal device supports ONVIF specification and functionality required to provide the appropriate Web Service. Server data interaction with the client using the SOAP protocol. ONVIF other parts such as audio and video streaming through RTP / RTSP conduct.

The advantage of Onvif protocol:


Compatible: Different factory offer products, all through a unified “language” to communicate. Facilitate system integration.

Flexibility: end-users and users do not need to be bound by the integrated solutions inherent in certain equipment. Greatly reducing development costs.

Quality assurance: expanding the market-oriented specification will follow the norms but also to meet the needs of mainstream users.

The difference Between Megapixel HD Lens and Common Lens

First, different definition.

For Common Lens,the resolution in central portion of the image is the highest,while the edge is relatively worse.The general resolution of Common Lens can reach  500,000 pixels. But HD lens is completely different. The following are three key factors that determine the resolution of lens:

1. Material and Purity of the Lens.The fewer impurities,the less interference of light it produces, the higher resolution the image will be.

2.Grinding precision of the Lens.The grinding precision is determined by the grinding equipment. The current difference between domestic and foreign lens is reflected at this point.

3.Coating precision of the Lens. Precise control of the coating process is one of the determinants of lens resolution.

In addition, Megapixel HD lens mostly use aspheric lens design.This can reduce aberrations.Compared to Common Lens, this design not only improve the resolution but also it’s a miniaturized design. Aspherical lens technology use special optical design techniques,the image from center to peripheral portion have high-definition and high-contrast images. It improved by about 2.5 times higher resolution than traditional lens. It can even ensure high-quality image after cutting or optical zoom.

Second,different transmission spectrum.

Spectral transmission ability can help improve image resolution. The Lens transmission on broadband light will greatly improve the amount of light for camera target surface, enhance the contrast and brightness,and perform richer details of image.As for the differences of spectral correction capability, only a broad spectrum of transmission capacity for high-definition imaging is not enough. If the lens lacks the correction capability for spectrum, it will cause some wavelengths can’t form image accurately on camera target surface and result in double image and virtual image. This broadband light transmission technology can’t work on common lens even by coating, which is the difference between Megapixel HD Lens and common lens.

Digital Zoom VS Optical Zoom

Source: www.mvteamcctv.com        Released on: Jan. 7, 2015

Zoom, means the ability of a camera to magnify a picture. Pan-Tilt-Zoom cameras and some fixed cameras have lenses that zoom in on an object.  In other words, it magnifies the object of the video, such as a car in a parking lot, so that it can be seen in much better detail.

Zoom is a very important feature of video camera lenses. By making the image larger, it is possible to watch intrusions developing from some distance away from the doors to a building. When comparing the zoom features of a camera lens, it is absolutely critical to understand the difference between digital zoom and optical zoom.

Digital Zoom, It cuts out a section on a distant image, not actually getting you closer to the object but by magnifying the lack of clarity that already exists.

Optical Zoom, is like standing closer to the object, you can see it clearly.

Take an example of digital zoom and optical zoom.
