Security Styles House, Where, When, Why and which ones to use

Security cameras come in various types and styles features and specifications that can be overwhelming for someone without a degree in electronic engineering. We will go through all the main types of CCTV security cameras, where to use each style and explain some of the basic specifications so that you can choose what type of equipment, closed circuit television is right for your security system.

Bullet Cameras

Bullet cameras are water resistant and tend to be smaller than other types of security cameras. They come in various sizes and forms, ranging from the size of a lipstick with the size of a soda can be typical. Bullet cameras are also called lipstick cameras, cameras or camera tube missile. If you are looking to see at night or infrared cameras, you will find the largest selection between the bullet cameras.

Dome Cameras

Dome type security cameras are the most popular style of security cameras. They usually have a base with a screw on the dome. The domes are polarized so that is difficult say where they are pointing, which makes them very popular for retail. Most cameras are plastic domes, but you can check the section the dome of the vandal-proof armor domes tend to be weatherproof with metal bases and sealed polycarbonate domes.

Armor Domes

Armor dome cameras, security, vandalism or domes tend to be slightly larger than the standard domes. Them are more resilient in their construction and usually have high resistance seals that makes weatherproof for outdoor installation. Most of the domes higher quality armor have a cardan shaft 3, which allows them to be mounted on a wall and a roof. Armor domes are available with fixed or adjustable lenses lenses, and with or without nightvision.

Box Cameras

Safety cameras, security cameras or professional style are most versatile style camera CCTV available. They usually do not include a target or an assembly, so you have to buy the lens and the indoor or outdoor mounting housing separately. They are more complicated than the domes or bullets, but the cameras allow special lenses box (ie number plate recognition) and quality controls generally have more video than other styles of security cameras. If you are mounting a box camera beyond will require house outdoors.

PTZ Cameras

PTZ Pan Tilt Zoom cameras or are the most complicated style security camera. These cameras PTZ dome cameras are generally large motor and internal components that enabled the camera to be controlled from the DVR, or remotely via a PTZ controller. These cameras use 485 to get the controls and programming, so that its DVR may require one RS232 485adapter. PTZ security cameras can also be programmed to run patterns. The speeds range from 10 degrees per second to speed domes which can move above 300 degrees per second.

Hidden Cameras

Hidden security cameras, hidden cameras, cameras spy are some of the most popular styles of security cameras available. These cameras use pinhole glasses with lenses and are generally very small enclosed in some other device that does not look like a camera. Motion detectors, sprinkler heads, smoke detectors, clocks, and custom configurations are common homes for covert security cameras. Some hidden cameras also come with built-in microphones. Check your local laws regarding surveillance audio.

Infrared / Nightvision

Infrared cameras and night vision cameras are extremely popular with our customers. These security cameras offer night vision clear color images during the day, and black and white images at night. At night, infrared security red cameras and provide the chamber with artificial light that can only be seen by the camera. These infrared cameras operate even in total darkness. LED more than one camera has, the farther you will see at night. Night vision cameras are available in weatherproof bullet, dome and styles Armor dome.

Low Light Cameras

Low light cameras are generally not able to see in the dark total, but are excellent for areas where video needs to clear security 24 hours a day, and there is some light available. These cameras, also Low Lux or chambers called Day / Night Cameras can use a function that calls the senses to provide color images even in low light conditions. Cameras with meaning-up sometimes have to be programmed during installation as sensitivity to light and shutter controls are set via On Screen Display (OSD). Low light security cameras are available as domes, bullets high-end and box cameras.

Lighting required

Houses marked with the lighting required tile needs better lighting. These cameras have a lux rating of 0.1 or higher and are generally best for installation in offices or homes where there are usually better lighting available. (The lower the number of lux is, the better the camera be able to see in low light. Some vendors call these day / night cameras, because they have a relatively low lux rating 0.1Lux, however, in our experience, which may be technically true, but far from the video quality of low light than people expect.

Interior

interior security cameras do not have time stamping. Water and moisture kill a security camera faster than any other condition, So inside, these cameras must be installed in places where not see condensation or temperature extremes. interior security cameras only come in styles dome and PTZ covert and styles.

Outdoors

Outdoor cameras come in several. scores of bad weather Starting with "IP" (degree of international protection) and end with a number above 54. The higher the number, time more resistant to the camera. Typically, this is the standard IP65 rating, which means that a camera with an IP65 rating can withstand a direct water stream. IP67, a camera is waterproof up to 1 meter. Outdoor use weatherproof or chambers where temperature and condensation is a problem, like the inside of a refrigerator cabinet or in a garage with a large amount of dust.

Outdoor Housing Required

The outer shell category is necessary for our styles advanced security cameras, cash and cameras that require a separate unit that is placed outdoors. Boxes are available separately in our section accessories and come with or without heaters and fans for the winter and thawing in the refrigerator unit in the summer.

fixed lens

Houses that are marked with the tile come with a fixed lens fixed lens, not adjustable. These cameras typically have an angle 3.6mm lenses provide semi-wide an image that is 74 degrees wide. The higher the number in mm lens, the greater the vaccine will be, and vice versa. domes covered with fixed lenses can be adjusted by separately through the purchase of mini-lenses in our accessories section.

Adjustable lenses

Security cameras with lenses manually adjustable, sometimes called varifocal or zoom lenses allow the user to manually adjust the angle of view when the installation of the cameras. These cameras allow the installer to mark the level of detail you want to see in your shot and are very useful for shots door or cash register where the views detail is very important. The lower the number of lenses is, the larger the shot will be and vice versa. Lenses with wider ranges are more versatile and can be set in a wider range viewing angle. These lenses also Iris control openings giving the user the best light level adjustment without having to make changes installation. varifocal lenses are available in dome, bullet truss domes and cameras.

Motorised lenses

Security cameras with motorized lenses are called cameras with zoom or PTZ cameras. These cameras can be controlled electronically zoom in and out in real time. They require 485 RS232 adapter to control and are nice to have when someone is seated from the DVR and is able to determine the best angle of vision of the situation. Motorized lenses usually are dome PTZ cameras and style as an option in the box security camera style.

What exactly a TVL?

TVL is a number of lines of resolution the effect of television, the greater the number of TVL camera, the higher image quality of this camera. Basically, the TVL is a count of the number of horizontal lines a camera can reproduce. This measure was initiated as a way for the TV broadcaster said they were original to broadcast in a higher resolution than they actually were, but today is a useful measure to determine the video quality comparison between two separate chambers. Today, the industry standard seems to be 420TVL resolution. High resolutions begins 480TVL around, though many cameras are available with resolutions far beyond that. 540TVL, 600TVL, 650TVL and 700TVL cameras are not uncommon. This is a scale Mobile, of course. The difference between a camera and a camera 350TVL 420TVL be more dramatic than that between 420 and 480TVL a qualification. However, As a general rule, when it comes to TV lines, the higher the number, the clearer the image.

What is Lux, and why important?

Lux is a measure of illuminance or in other words, a measure of the amount of light available. The number of lux camera tells you how much light is necessary for the camera to provide a usable image. Note that the term "use" is very subjective, and that ratings may be lux "Adjusted" by unscrupulous manufacturers and sellers to look like they have a better camera closed circuit television. In general, the smaller the number lux of a camera, better than the camera held at night or in low light. Be careful to compare scores from different camera lux manufacturers as the number of lux is based on the f-stop in which it is measured, usually seen as 0.1 Lux@F1.2. This topic requires an entire article to discuss properly, but should now have enough information to make an informed decision about which product is right for you.
