Bullet camera that can be placed underwater or in extremely damp/wet conditions where a normal weatherproof camera might leak. Applications include pipe inspection, refrigerated rooms, restaurant kitchens, marinas, etc.
It is a tool used to protect people, property, enhance safety, and improve productivity.
Closed Circuit Television is a group of cameras, monitors and accessory equipment that work together as a system and are interconnected by various types of cables.
A noise reduction device includes a two-dimensional noise reducing unit for reducing noise by arithmetic processing within an image, a three-dimensional noise reducing unit for receiving the video signal from the two-dimensional noise reducing unit and reducing noise by arithmetic processing between images, a first noise reduction intensity setting unit for setting noise reduction intensity of the two-dimensional noise reducing unit, and a second noise reduction intensity setting unit for setting noise reduction intensity of the three-dimensional noise reducing unit. The second noise reduction intensity setting unit sets the noise reduction intensity of the three-dimensional noise reducing unit, so that the noise reduction intensity of the three-dimensional noise reducing unit becomes lower as the noise reduction intensity of the two-dimensional noise reducing unit becomes higher
The 940nm infrared LEDs are virtually invisible (99%)to the naked eye. These LEDs produce virtually no light that the human eye can see. The light that comes from these, however, can be utilized by infrared cameras. The 850nm infrared LEDs is not as invisible as a 940. They have a very slight reddish glow to the LEDs themselves. The fact that they do have a very small amount of light that the human eye can see means directly relates to how well they can illuminate. A 850nm LED will illuminate better than a 940nm LED, all things being equal. The lower the NM number gives it better illumination ability. Operating voltage, amperage, manufacture and even actual size of the LED all play vital roles in the brightness and lifespan of an LED. This is how our 48 LED and 28 LED (850nm) cameras can illuminate as well or better than our 104LED (940nm) camera. If a camera has 940nm infrared LEDs it will be labelled as such in the description.
Lux is the measure of light the camera needs to reproduce an image. The lower the Lux number, the less light the camera requires. A black & white camera will grasp an image longer than a color camera. For instance, a camera with a LUX rating of .0003 will see MUCH better in the dark than a camera with a .03 LUX rating. When we specify low lux, typically the lux is .0003.
Varifocal means that the FOV and mm lense of the camera can be adjusted. Most of our cameras have a fixed lens. This means if you purchase a camera with a 3.6mm lense, you cannot change it. A few of our camera have varifocal lenses. These are lenses that can be adjusted after purchase. They will be indicated as varifocal lenses and the adjustably will also be listed. It might say SSC-111WC Varifocal 4-8mm. This means that the camera’s lense can be adjusted anywhere between 4mm and 8mm to achieve the desirable Field of View (FOV). Keep in mind this is different than the lense being in focus. All of the cameras we sell already have the lenses in focus for a crisp and clear picture.
The minimum light requirements for recording are measured in lux. A decent standard color CCD camera might be .5 to .1 lux. A decent B&W CCD camera might be about .01 A low lux camera would be more like .003 to .0001 The smaller the number, the better ability to see in the dark. But still do not assume if somewhere is pitch black you can still see well with a low lux camera.
This will require the use of a DVR card, USB capture card, or USB DVR. Very few computers come with the hardware and software necessary to accept composite inputs so it is very common to have to purchase these items aftermarket. A DVR card is the most recommended for long term surveillance. This will allow for motion activated recording, timer recording, remote access, and many other features. A DVR card must be installed in a vacant PCI slot on your pc motherboard. For laptops a USB capture card or USB DVR will connect via a USB port and provide very basic surveillance. you will then use the software that came with the USB hardware to record the video.
Yes you can. All of our DVRs have the functionality built-in to view the cameras over the internet. You simple type in the IP address (What’s an IP Address). of the DVR computer from any computer with an internet connection and you will begin viewing the cameras.
The “Digital Time Code Embedded” function is embedded in MPEG data stream. Therefore, the exact time each frame is recorded will be stored. It is very useful when users want to find the video at an exact time or a certain time interval. If an IP camera doesn?It support this function, users have to search for the whole video stream by looking through the video, which takes a lot of time. Some cameras provide software solution to simulate this function. However, this is not as accurate. Video streams with Digital Time Code Embedded are so-called “Smart Video”, and can enable a lot of useful applications at client site.
The other advantage of Digital Time Code Embedded is that it provides watermark on the video streams. Since the time code is written in the video stream, if the video is modified by others, the time code will disappear from the video stream, and therefore, the time code can act like a watermark for the video stream and users will find if the video is modified by unauthorized people.
The IP cameras provide two RJ-45 connectors. One is WAN and one is LAN. Both of them are 10/100. The difference between a WAN and a LAN is that WAN is to be connected to the internet, while LAN is to be connected to a local network. Since the internet’s bandwidth is very critical, It provides hardware QoS (Quality of Service) on the WAN port to ensure the bandwidth when uploading video streams through the internet. Also, the WAN port is equipped with PPPoE (Point-to-Point Protocol over Ethernet) which enables the IP camera to be connected to an ADSL or cable modem without the need to go through a router first. If the IP cameras are to be deployed at a large area, it will be very costly to provide routers to each IP camera. Using IP cameras with PPPoE built-in, installers will be able to save a lot of cost over routers.
If an IP camera can support DDNS (Dynamic Domain Name Server), users can set the IP camera at a virtual domain name (such as cam1.kitchen.Taipei.xxx.xxx) at dynamic IP, and be able to view this IP camera anywhere that has access to the internet. It saves money when setting up the broadband with service provider, whether it?Tt’s ADSL or cable modem, since fixed IP is not a must.
Some IP camera manufacturers claim to provide DDNS. However, they are software solution that needs to be installed at client site’s PC. Therefore, it requires users to see those IP cameras at the PCs that have installed the specific AP from manufacturers. This is not as user-friendly. The IP Camera have DDNS function built-in the IP camera so that users can view the IP camera from anywhere.
No. The camera works fine also in local network without the internet connection. If the remote users are in the same local network, it’s not necessary to connect the IP & Analogue cameras to the internet.
Yes. You can record the video at remote / local by using the software provided by the IP camera manufacturer. The ability to record the video at remote site is a major advantage of IP camera over traditional analog camera. NAS (Network Attached Storage) is very useful in video storage, and is easy to install.
It depends on both the resolution and frame rate. It also depends on the compression technology the IP camera is using. Below are three of the most popular compression technology and the required bandwidth and other important information.
Compression Protocol M-JPEG MPEG-2 MPEG-4
Compression Rate 6 30-40 200-500
Resolution 352 x 288 720 x 576 720 x 576
FPS 25-30 fps 50-60 fps 25-30 fps
Bandwidth Required 1.5Mbps 4-15Mbps 10K-1Mbps
Also, please note that 30 frames/s (NTSC) is the required frame rate to provide continuous motion and good quality (DVD like) video.
A web camera is connected to a PC, normally through USB, and uses the PC to make video available to other viewers. It will not work without a PC locally connected to the camera. An IP camera usually stands alone, and combines the functionality of a high-end web camera, the PC and network interface into one network-ready product.
Video surveillance is everywhere today, from private home installations to massive enterprise deployments. And while the migration from analog to IP has been on the rise for several years, many companies of all sizes and shapes have been hesitant to make the leap to an IP-based video surveillance installation. Using HD cameras, IP-based systems bring the inherent advantages of network storage to video surveillance as well as the overall storage needs of a business.
There are the issues of the initial cost, the need for some technical understanding, and perhaps other concerns, but, really, why haven’t more companies made the switch to an IP-based video surveillance system?
Here are 10 reasons why now is the perfect time for companies to switch from legacy analog cameras and DVR systems to HD cameras and dedicated network video recorders (NVRs) for all their video surveillance needs.
1. Analog End Of Life — Low-definition analog camera systems and DVRs are beginning to reach their end of life. This is largely because of competitively priced, HD -definition IP cameras and NVRs that use advanced hard drives designed for professional use with a backup design commonly known as RAID (redundant array of independent disks). With RAID, data is spread across multiple HDDs. If one drive fails, the files have been backed up on another hard drive. Additionally, the maintenance expenditures required to support legacy video hardware create an urgency to upgrade equipment.
2. Ease Of Installation — A common misconception is that NAS (network attached storage)-based installations are much more complex than DVR-based. While that may have been true in the past, manufacturers have recently promoted features like universal plug-and-play camera recognition to make NVR installations as simple as possible. In addition, as manufacturers design new IP cameras, ease of installation is a primary feature.
3. Existing Infrastructure Use During Switch — Because a lot of companies already have an analog system in place and want to maximize their existing investments, manufacturers have created solutions, like encoders, to support hybrid environments. As analog/DVR components start to fail or reach end of life, users can switch out components one at a time to begin the upgrade to an IP camera and NVR installation. This hybrid environment technique maximizes companies’ initial investments and provides them the flexibility of funding their video surveillance upgrade over time.
4. Cost-effectiveness — Another misconception is that IP camera and NVR deployments are prohibitively expensive. A DVR may be cheaper initially than an NVR, but the NVR is no “one-trick pony” — it not only can manage the video surveillance requirements of a company, it also can operate as the foundation for the overall storage and data management needs of a work group, remote location, or stand-alone business. And as prices of IP cameras continue to drop, HD cameras bring significantly improved capabilities.
5. Scalability — As you start adding cameras to an existing video surveillance system, the migration to IP cameras is the most logical choice. Network-IP cameras can be added to an installation using existing analog cameras, thereby allowing a company to migrate over time to today’s HD standard rather than staying with yesterday’s outdated solutions.
6. Reliability/Durability — NAS-based, IP-video surveillance systems have proven to be faster, more reliable, and every bit as durable as older systems utilizing DVRs and analog cameras. When you consider all of the inherent advantages of NVRs with RAID data management and professional hard drives, the move to NVRs combined with IP cameras makes even more sense.
7. Manageability — The ability to access and view video files from any location in the world via mobile apps and remote clouds (assuming an Internet connection) is an obvious benefit of an IP-based video surveillance storage solution.
8. Image Quality Enhancements — More and more affordable high-definition IP security cameras are available in the market. These cameras provide better resolution, expanded surveillance environments, and highly detailed images. And after all, doesn’t everything look better in HD — including your video surveillance security files?
9. Regulatory Compliance — Due to security concerns and a higher compliance environment on a global level, tighter regulations have been imposed on a variety of industries. Depending on an industry’s regulatory standards, a company may face considerable surveillance video retention demands. That can be costly and danger-prone with yesterday’s onsite analog approach to video surveillance. It’s easier than you think to utilize local and remote network storage for retention requirements and peace of mind.
10. Expanding Capabilities/Features— Video surveillance features are continuing to expand, enabled by private cloud, remote video apps, and analytics to enhance solutions. IP cameras can offer a range of functions from basic to advanced analytics in almost any way imaginable. In addition, low-cost storage options like hosted video make network video a much more affordable option than location-based analog solutions.
