HD VIDEO IS SUPERIOR
大乐透7十4复式多少一投注there is no comparison between hd video and older analog technology. hd video is much higher resolution and displays far better detail and clarity. in-fact, you can expect our hd cameras to be at least 3-5 times sharper than standard analog cameras. this is because hd cameras are measured in megapixels. each megapixel is comprised of 1 million pixels or dots on a screen. 1mp and above is considered high definition which is the equivalent of a 720p digital broadcast signal. full hd television is broadcasted at 2mp or 1080p. a 4k ultra hd video broadcast is equivalent to 8mp. the higher the megapixel count the sharper the image. one great benefit of hd cameras is that you can digitally zoom or blow up an hd picture and the integrity of the image will remain largely intact rather than appearing pixelated or blurry like the older analog cameras.
DVR VERSUS NVR
大乐透7十4复式多少一投注there are 2 types of hd security camera technologies; hd over coax and ip based. a recorder that supports hd over coaxial cable is called a digital video recorder (dvr). ip cameras connect to a (nvr) network video recorder using ethernet or network cable. both dvr and nvr units provide the same basic functionality. either can be used to view live or recorded video and also to view your cameras remotely on a smartphone, tablet or computer. the main differences would be the type of cable used to connect the cameras. also, it is important to note that hd over coax recorders are backwards compatible for older analog cameras. in other words, you can use both hd cameras as well as any existing analog cameras with our hd over coax digital video recorders.
IP NETWORK SYSTEMS
many new customers are interested in ip cameras. we offer 2 ip camera product lines; green-line and blue-line. you should always match products with the same color code for the best compatibility and overall user experience. our network video recorders are able to display ultra hd images up to 8mp or 4k. ip cameras are run using cat5, cat5e or cat6 ethernet cable. all of our ip cameras are poe (power over ethernet) meaning that both power and video are transmitted over a single cable for very simple installation. standard ip cameras can be run up to 325ft. we offer additional hardware such as repeaters and switches for customers who require further cabling. a unique feature of our green-line (surevisiontm) ip camera line is the ability to transmit both power and video over 1,000ft using pure copper ethernet cable.
HD OVER COAX SYSTEMS
大乐透7十4复式多少一投注hd over coax cameras are run using traditional coax cable with bnc video connectors. our digital video recorders can also produce ultra hd images up to 8mp or 4k, and are also compatible with older analog cameras. the most common type of cable used is rg59 siamese cable. the term siamese means there are actually 2 cables (power and video) running side by side that can be pulled apart. this is important because hd over coax cameras are not powered from the recorder. rather, hd over coax cameras can be powered using an individual power adapter or a multiple output power when running multiple cameras. hd over coax is extremely beneficial when a customer has existing analog infrastructure in place and wants to also add hd cameras. another benefit of hd over coax is that video can be transmitted well over 1000ft distance. our digital video recorders support all of the hd over coax technologies.
we carry many different styles of cameras. a lot of people like the bullet style cameras due to their sleek housing. other people prefer a dome style for their discreet, low profile and vandal-proof design. a large majority of the cameras we offer are fully weatherproof for indoor or outdoor use. the size of the camera lens will determine its viewing angle. our widest lens size is 2.8mm and will produce a 110 degree super wide angle which is good for covering the entire immediate perimeter. a popular 3.6mm lens will display a 90 degree wide angle. our most popular lens size is the 3.6mm which offers a 90 degree wide angle. customers like wide angle cameras because they offer the most bang for the buck. however, if you need to focus on an object that is much further away then you will require a more powerful lens such as 8mm, 12mm or even a 50mm or 100mm lens for good close up images of objects that are over 100ft or even 200ft away. many of these cameras offer a varifocal lens that you can adjust to achieve the perfect angle. better yet, many of the varifocal cameras have a motorized lens so you can simply adjust the angle directly from your recorder or remote device. in short, there is always going to be a compromise between the width of the angle and the distance you can see. the perfect solution may sometimes be a combination of wide angle and varifocal cameras.
WIRELESS CAMERA SYSTEMS
wireless cameras have also become popular with the release of the many consumer wifi gadgets available today. these cameras are often limited in terms of selection, clarity, reliability and function. it is important to understand that the term “wireless” mainly applies to video transmission. many of these consumer devices are battery powered. we do not offer battery-powered cameras because they need to be recharged, and as a result, are less reliable. we do offer professional-grade wireless ip camera systems that can produce 3mp images. however, these cameras do require power, and it be somewhat uncommon for a power outlet to be located where the camera is mounted. another consideration is that wireless cameras can be subject to interference or loss of wifi signal. our wireless cameras can transmit a highly reliable video signal up to 75ft. we recommend hardwired cameras for applications with further distances or structures that prohibit adequate wifi signal.
STORING VIDEO FOOTAGE
大乐透7十4复式多少一投注another consideration when designing a video monitoring solution is storage. most customers want to store their captured video footage for 7-10 days. all of our recorders have internal hard drives inside the units where the video is stored. we only use surveillance grade hard drives for the best durability. the higher resolution cameras will require more storage simply because they consume more data. this is why we offer customers the ability to increase the size of their hard drive to meet their exact storage needs. a majority of customers set their recorder to record only when motion is detected in order to save hard drive space. for example, a 4 camera hd recorder with 1tb hard drive can record continuous video at 4mp for up to 7 days. if the same recorder is set only to record on motion or on a schedule the storage time will increase very significantly. less expensive recorders only have space for a single hard drive. many of the units we carry have multiple hard drive bays to accommodate more video storage if and when required.
