In the next 3-5 years analog security cameras will be replaced with High Definition (HD) Analog Cameras. Until recently, in the world of security cameras we had to choose between analog security camera systems or IP security camera systems. In the analog world, which has been accompanying us for 50 years, there has been a rapid evolution: Analog HD Security Cameras. Now we are presented an interesting option in the world of surveillance cameras, the result of which any outdated analog security camera system installation can be upgraded to High Definition (HD) without resulting in a expensive financial investment.
HD-TVI stands for High Definition Transport Video Interface. It was developed by Techpoint and adopted by many manufacturers, most notably Hikvision the largest manufacturer of HD-TVI security cameras in the world. HD TVI security cameras can convert the digital signals to Analog: it extends the transmission distance, reduces the total cost and takes less storage capacity. A TVI security camera currently support 2MP (1080p) security cameras resolution using the same coaxial cabling techniques used by traditional analog security cameras. Also, TVI security camera systems make it easy for users with existing analog security camera systems to upgrade to an HD security camera system by using (most of the time) their existing cable infrastructure. HD TVI security cameras can also supports HD video signal (1080P/720P), audio signal and digital signal transmissions.
Many Analog Security Camera users prefer the low-cost and easy solution to upgrade existing system to HD so some worry about having to rewire, re-install or add new network devices for upgrading. By replacing the existing Analog Security Cameras and DVR Device with the latest HD-TVI Security Cameras and its compatible DVR, users can upgrade their surveillance system to a brand new 2MP 1080p HD System, this doesn't require extra installation knowledge or cost for replacing the coax cable.
Another advantage is that HD-TVI Camera Systems come from a US-based company that does not supply to only one manufacture, so the chipset is open, meaning it’s not sealed so users can modify their HD-TVI System to support different brands. Many customers like to match their DVR and Security Cameras with different brand because having a wide choice may allow them to save more money.
For recording, HD TVI security cameras must use a compatible Digital Video Recorder. There are DVRs being manufactured specifically for TVI security camera systems. However, there are also Hybrid Video Recorders (HVR) compatible with both analog security camera systems and TVI security camera systems (720p and 1080p models). Hybrid Video Recorders allow users to connect all of the same types of security camera technology to their Hybrid Video Recorder or mix and match Analog, HD-TVI, and IP technologies to the same security cameras recording solution. Hybrid DVRs are also very convenient for people that have existing analog security camera systems and want to upgrade to High-Definition 2MP/1080p Resolution or higher. They can leverage their existing security camera system and add HD TVI security cameras over time.
Analog Security Cameras capture an analog video signal and transfers it over coax cable to a DVR (Digital Video Recorder). The DVR will convert the analog signal to digital, then compress it and store it on a hard drive for later retrival.Read More
HD-TVI Security Cameras currently support video resolution as high as 1080p by using the same coaxing cabling as Analog Cameras use which, makes it easier for people with old Analog CCTV Systems to upgrade to an HD system.Read More
IP Cameras are able to deliver higher resolution and offer digital zoom and on board digital processing. A higher number of pixels will provide a better digital zoom so you'll see further into the distance without degrading the image.Read More
Megapixel Security Cameras deliver the best image quality available, capturing a super high-resolution image and allowing you to digitally zoom in on specific details with great clarity when reviewing recorded Surveillance videos.Read More
Color Night Vision Security Cameras contain powerful image sensors that are more sensitive to light allowing the sensor to absorb more visible light so the cameras will continue to provide full color video images in low-light conditions.Read More
Thermal Seurity Cameras sense thermal energy instead of using visual light to construct images. Since it doesn't see light, it will see at night as well as it does during the day. It sees through obstructions and its not affected by smoke, dust or fog.Read More
Wide Dynamic Range Security Cameras help to figh natural and artificial lighting. These cameras have a special software which allows them to balance too bright or too dark rooms creating a balanced and high resolution video shot.Read More
Wireless Security Cameras allow you to place them up to 1.5 miles away from your local area network. They use top-of-the-line technology to ensure a secure and reliable connection and offer the same standard features as a wired camera.Read More
Having a security system as necessary as paying for services.The price depends on the features and form factors of the equipment, as well as the amount of devices installed, the distance, whether, and if its a wired or wireless system.Read More
Audio Security Cameras have built-in microphones that allow easy audio recording. Hidden audio security cameras are illegal, so you must get the consent of at least one person in the conversation or hang sign where they are installed.Read More
A Network Security Camera can be described as a camera and a computer combined in one unit. Their significantly high video resolution will allow you to capture more area per camera and zoom-in to enhance minor details.Read More
Image sensor is the element of an electronic camera, which detects and captures the information that makes up the image. This was achieved by converting the attenuation of light waves into electrical signals.Read More
Power over Ethernet (PoE) works by using a single network cable to provide both data connection and electric power over to an IP Security Cameras. This will result in lower cost, less downtime, easier installation and maintenance.Read More
PTZ stands for Pan, Tilt and Zoom. This refers to the capabilities of automated cameras and video recorders. Has the ability to rotate, usually in a full circle, to tilt at different angles up and down, and to zoom in on particular objects.Read More
Video compression techniques consist of reducing and eliminating redundant video data so that the digital video file can be sent through the network and stored. Different compression standards use different methods to reduce data.Read More
Frame rate, fps or frames per second, is the number of frames (images) your camera can take per second. The continuous succession of these frames produces the idea of movement because of the minimum differences between them.Read More
4K security camera is a digital camera with a horizontal resolution of around 4,000 pixels and a vertical resolution of about 2,200 pixels. It is twice as high as the resolution of an existing standard high definition (HD) security camera.Read More
