What is the HD Security Camera System?
The ahd security camera system is an analog high definition CCTV solution that works over existing coaxial cable. It connects to a digital video recorder (DVR) and offers advanced features like night vision.
AHD over coax technology solves some of the main issues that have prevented other HD security cameras from catching on. It supports 960h resolution and up to 500 meters transmission distance over traditional 75-3 coaxial cable, or UTP cable with video baluns.
1. High Definition
When purchasing a security system, the resolution of the images is the most important factor. It can make the difference between being able to identify an intruder’s face, see license plate numbers on cars or know who ran over your garden gnome.
The higher the resolution, the more detail you’ll be able to see in your footage. ahd security camera system This will allow you to capture the moments that matter most.
High definition cameras will also give you a clearer picture in low light conditions. In addition, most AHD cameras have built in audio with Audio-Over-Coax (AOC) which means you can transfer audio along the same coax cable vs having to run an extra pair of wires for audio.
There are also hybrid digital video recorders available that support both AHD and CVI cameras so you can upgrade over time to HD while keeping your existing CCTV systems in place. These DVRs have apps that allow you to monitor your cameras from any device, even mobile phones, so you can keep an eye on your property and family while away from home.
2. Long Range Transmission
Unlike IP cameras, which can be connected to the network with ethernet cables, AHD security systems use standard coax cable to transmit video footage. This makes them the perfect choice for new installations and for upgrading old analog CCTV camera systems.
AHD security cameras transmit HD 720p or 1080p images over long distances on quality coax cable, making them ideal for both new and existing homes and businesses. Compared to IP network cameras, AHD systems consume less bandwidth and don’t suffer from latency or interference.
While wired systems are the best option for homeowners and businesses with a permanent location, the longer installation process can be a drawback for those who want a temporary solution. In contrast, wireless (or wire-free) systems send footage from cameras around the home to the Wi-Fi, where it can be viewed in real time or stored for later viewing. However, they can be subject to interference from other wireless signals and broadcasts. As a result, it is essential to test the resolution of your security cameras before purchasing. Some AHD security cameras claim to be 2000TVL, but actually only have 960H resolution.
3. Better Compatibility
AHD cameras offer a clearer image than traditional analog CCTV cameras, allowing you to see more detail in recorded footage. This is especially important if you need to identify faces or license plates. AHD camera resolution is also higher than traditional CVBS cameras, resulting in sharper video.
Many AHD cameras claim to have 2000TVL or higher resolution, but this can be misleading. In reality, the majority of these cameras are actually 960p AHD. They will work with traditional 960H DVRs, but the resolution is lower than a normal 960P CCTV camera.
AHD security camera systems are compatible with existing coaxial cables, making them a great choice for upgrading your existing CCTV system without having to run new wires. They are also compatible with all three high-resolution analogue technologies (HD-TVI, HD-CVI, and AHD), as well as traditional low-resolution analogue technology. This makes it easy to mix and match your analog cameras without any compatibility issues. Most AHD recorders support both analog and IP cameras, allowing you to upgrade your analog CCTV system with ease. They also often support H.265 video coding, which reduces storage space requirements by up to 40% with the same video quality.
4. Low Cost
AHD cameras are around the same price as old analog CCTV technology and much less expensive than IP Network cameras. In addition to the lower cost, AHD systems do not require any bandwidth considerations or suffer from latency and IP collision problems like other camera technologies.
Our AHD security system kits are perfect for new installation or upgrading existing analog systems. Using new or existing coax cables, AHD transmits HD video from cameras to the DVR at 720p or 1080p resolution. This makes AHD ideal for retrofit installations and is a popular choice for replacing older analog CCTV technology.
Elinz AHD security cameras are equipped with 36pcs IR LED and 3.6mm lens to provide an excellent night vision performance with up to 25 meters in distance. The AHD cameras also have built-in WIDE DYNAMIC RANGE and ANTIFOG functions for better shooting in low light conditions.
Unlike other security cameras, our AHD DVR recorders support H.265 video coding which allows you to save up to 50% of the hard drive space with the same video quality. This can help you maximize the usage of your hard disk storage and lower your total cost of ownership.
5. Open Standard
With different HD over coax technologies varying in cost, it’s important to evaluate the cost and quality of each before deciding on one. Additionally, it is worth considering how Dual Lens Camera much distance can be covered by the cable before video transmission quality begins to degrade.
Another consideration is the security of the camera system. It’s best to consider a CCTV camera that offers encryption to protect the footage it records. It’s also important to look into whether the camera manufacturer has had a history of data breaches in the past.
The open standard offered by ONVIF (Open Network Video Interface Forum) helps streamline device management across a range of brands and models. ONVIF-compliant devices adhere to the same specifications, making them easier to integrate into a unified system. However, not all camera manufacturers are ONVIF compliant and may only support earlier versions of the protocol. This can result in limited functionality even when a device claims to be ONVIF compatible. Be sure to choose a device that adheres to the latest version of ONVIF to ensure maximum compatibility with other ONVIF-compliant devices.
