How to Shop For the Best HD CCTV Camera Price
While IP cameras are becoming the standard, there’s still a huge demand for HD CCTV. Many organizations have a large infrastructure of traditional analogue cameras on coaxial cables and want to upgrade them without ripping out and replacing everything.
This is where HD-TVI, HD-CVI and AHD CCTV cameras come in. These technologies use industry-standard coaxial cables to deliver 720p and 1080p resolutions.
High Definition
High definition security cameras are growing in popularity because of their ability to capture clearer images than traditional analog ones. They can even be used to identify license plates and faces, making them a great tool for deterring crime. However, when shopping for an HD surveillance camera, it’s important to choose a trusted brand. Check out the manufacturer’s reputation and check for real-world video samples before making a purchase.
While IP cameras are the current standard, many organizations have an existing infrastructure with traditional analog systems. Fortunately, HD-TVI, HD-CVI, and AHD cameras work over existing coaxial cables like RG59 or RG6 to allow you to upgrade without the cost of replacing the entire system.
AHD cameras are similar to a regular analog CCTV camera, but have the added benefit of supporting 720p resolution over a 3+1 wire system. They also offer features like Wide Dynamic Range and a built-in microphone. They can be easily setup and managed using a user friendly On-Screen Display or the UTC controls located on the camera body. They also don’t require any network configuration or settings adjustments like an IP camera, making them much easier to set up.
Wide Dynamic Range (WDR)
WDR is a technology that allows cameras to capture images with high contrast between very dark and bright areas of the image. This feature is especially important for surveillance in environments with intense backlighting, such as outdoor entrances or rooms with windows. WDR is typically rated by a dB value, with higher values being better. However, a camera’s dB rating should never be the sole determining factor when choosing a surveillance camera. It is more important to prioritize forensic usability and image quality.
In addition to providing sharp images, WDR also offers more detail than standard CCTV cameras. This makes it ideal for environments where light levels change frequently, solar security camera such as lobbies or corridors near outdoor entrances that are often subject to sunlight and car light beams.
Unlike HD-SDI and IP network cameras, AHD cameras use a single coaxial cable to transmit video and audio, so installers don’t have to run separate cables. This is a major advantage when it comes to installation and maintenance costs. Additionally, AHD cameras are compatible with existing analog security systems and can be easily upgraded to HD over time.
Audio-Over-Coax (AOC)
Adding audio to your surveillance system allows you to hear the sound of an intruder and gives you a better understanding of what is occurring on your property. Using audio-over-coax technology, you can transmit the sound signal along with your video feed, without having to run an additional cable for audio signals. This is a great option for businesses that already have existing wired systems and want to add audio.
HD analog cameras can work on coaxial cables, making them the preferred choice for businesses that don’t want to rip and replace their existing wiring. In addition, they don’t require the same kind of network configuration and setting adjustments that IP cameras do. However, these cameras will still need to be connected to a recorder.
For the best results, you’ll need to use an AOC compatible DVR and a microphone that supports this technology. This will ensure that the audio signal is transmitted as clear and accurate as possible. You can find a wide selection of these cameras in our custom kit builder. Some cameras also feature a Black Glass front cover to increase LED efficiency and reduce insect attraction.
UTC Chip
The UTC chip in these cameras allows you to control the camera’s OSD menu directly from your DVR, sending commands along the video cable. It’s a great feature, especially for hidden cameras where you might be unable to reach the camera physically to change the settings.
These cameras are designed to be connected to a digital video recorder – also known as DVR – that digitizes the analog signals from the old CCTV cameras and records them onto a hard drive. The DVR can also perform all the digital functions of IP systems, such as remote monitoring and motion detection.
It is important to note that while these are HD Analog devices, they will ONLY work with a DVR that supports them. A no-name brand that is selling a cheap, low-quality product may be cutting costs in other places, such as reducing the quality of the image sensor or using a low-grade IC. This will have a significant impact on the overall quality of the product. This is why a manufacturer’s reputation is crucial when buying security products online.
Black Glass Front Cover
A common issue with CCTV cameras is horizontal lines on the footage. These are caused by electrical interference ahd cctv camera price on the single-chip CCD sensor and can occur when ambient light is too bright or certain types of lighting are used. It’s best to check that there isn’t a strong light falling directly on the camera or an electrical power source nearby. Also, it’s a good idea to test the camera with a test monitor to see if the picture is clear and crisp.
These cameras are designed to be connected to a digital video recorder (DVR). The DVR digitizes analog signals into a high-resolution digital format, so it can display and store video surveillance data on a hard disk. All of the cameras in this range come with Black Glass front covers that increase LED efficiency by about 8% and reduce the attraction of insects at night. They’re also water-proof, so they can be installed inside or outside, protected from the rain.
