AHD Camera Price – What You Need to Know
AHD cameras are great for upgrading existing CCTV systems that use coaxial cables. They offer advanced features and reliability with modern technology like Y/C signal separation, simulation filtering and 3D noise reduction.
Many of these cameras have an on-screen display that allows installers to access and change image settings using a joystick. They also have a microSD slot for recording footage locally.
1. High Definition
Unlike traditional cameras, HD cameras provide high resolution and image quality, which is essential for security purposes. High definition cameras also allow you to see more detail in footage, such as license plate numbers and facial features.
For those not familiar with technology terms like “high definition”, the term “HD” refers to a video format that has a higher resolution than standard definition (SD). Common HD formats include 720p and 1080p. The more recent 4K resolution is referred to as Ultra HD.
2. Wide Dynamic Range
Wide Dynamic Range (WDR) is a technology that allows cameras and sound systems to grab more colors and tones. This is especially helpful when dealing with scenes or recordings that have a lot of contrast between bright and dark areas.
WDR works by combining multiple images or video frames that are captured with different exposure levels. Then, these are fused together to create a single image or frame that has a greater dynamic range.
This is an important feature to look for in a surveillance camera because it can help reduce glare and dark spots. For example, places like lobbies and corridors near outdoor entrances often have light from the sun reflecting off windows but also have very dark shadows.
3. Night Vision
Night vision technology allows security cameras to see in complete darkness. This is possible because visible light makes up a small portion of the electromagnetic spectrum. The image sensor ahd camera price inside a night vision camera detects this invisible part of the spectrum and converts it into an electronic signal, which is then translated as a black-and-white image.
The quality of the image depends on how bright or dark the scene is. Infrared LEDs are used to illuminate the scene and can be positioned at different distances from the camera to achieve the best results. Some cameras also use digital noise reduction to further enhance the video clarity. This eliminates graininess and produces sharper images.
4. Motion Detection
The best motion sensor cameras keep you connected to your home through instant mobile notifications. They also feature proactive recording that initiates when motion is detected, eliminating the need for continuous operation and preserving storage space.
They’re great for catching intruders or unwanted guests, especially when combined with a security system with professional monitoring. They can also be used to trigger lighting and security alarms when someone enters a room or opens/closes a door (and more).
Look for sensors with adjustable sensitivity settings so they only alert you when it matters. This prevents the camera from being triggered by small movements like a cat or dog wandering around.
5. Weatherproof
Weatherproof cameras are able to withstand the elements such as rain, snow and high winds. They are perfect for areas that experience a lot of bad weather.
Cameras are rated for their ability to resist the elements using an IP rating system. The first digit denotes protection against solid particles such as dust and dirt, while the second digit indicates how resistant the camera is to moisture.
It is recommended to purchase a camera with an IP rating of at least 6 or higher. The higher the number, the more protected the camera is from moisture and other environmental factors. This can extend the life of the camera and improve its quality.
6. IR LEDs
Infrared LEDs are used to emit invisible light that the human eye cannot see for night vision. These lights are generally long-lasting and require little maintenance.
Smart IR technology automatically adjusts the intensity of infrared illumination, ensuring clear and detailed footage without overexposure or washout. This feature is perfect for indoor and outdoor surveillance.
All cameras in this range come with a day&night function that gives you a color picture during the day and turns to B&W at night. Enhanced features like Digital Wide Dynamic Range and DIGITAL NOISE REDUCTION help improve image quality in difficult lighting conditions. Several models in this range have invisible IR LEDs that do not generate any red glow.
7. MicroSD Card
The right memory card is one of the most important accessories a camera owner can purchase. A malfunctioning WiFi Camera or slow-performing card can erase precious memories.
Capacity: A camera’s resolution and recording duration can determine what size a storage card needs to be. High-resolution cameras require larger capacity cards.
Speed: Choosing an SD card with a high read/write speed is essential for smooth operation. Faster cards are especially important for capturing video and large image files in burst shooting modes.
Longevity: Some cards are built to withstand temperature and weather extremes, which is especially important for outdoor cameras. Look for cards labeled with the “high endurance” designation. These cards can handle more wear and tear, making them the best choice for the most durable cameras.
8. NAS
Many NAS products include a range of video surveillance services that are a great way to remotely monitor your property and keep an eye on your kids and pets. They can also be used as a security system for businesses and stores. This camera from HIKVISION has a lot of good features, including a rating of IP67 and the ability to pan and tilt. It can even take an ethernet connection from a PoE source, cutting down on installation costs and time.
It also supports Audio-over-Coax, letting you transfer the audio signal over the same cable as your video. However, you will need a NAS enclosure connected to this camera to make the most of it.
