AHD CCTV is an analog high definition closed-circuit television video surveillance standard that uses coax cable to transmit HD video from security cameras to DVRs. AHD supports 720p and 1080p HD video resolutions.
1. How to choose a CCTV Camera?
Choosing the correct CCTV Camera for your digital surveillance system is very important. The Digital CCTV Camera, together with a CCTV Lens, uses a CCD (Charge Coupled Device) sensor that captures the image and turns it into a signal that is sent to the monitor or surveillance system.
You will need to decide the following when choosing a cctv camera & lens for a digital cctv system:
- The Digital Camera Location: Will the camera be situated Indoors / Outdoors
- The amount or variance of light conditions for the digital cctv camera: Will the camera have to record in low-light conditions such as at night?
- The Field of View required for the camera: How wide or narrow an angle of vision is required
- The Focal Length - How far away objects you wish to record will be from the camera
- Your budget
2. Can old analog cameras still be use?
Yes. The AHD DVR is hybrid, it can be analog or ahd inputs.
3. What is the resolution for the AHD cctv?
It can be 720p or 1080p. The DVR AHD 2.0 can input 720p or 1080p.
4. What type of cable do AHD cameras use?
AHD CCTV cameras are connected to DVRs using the same type of coaxial cable as traditional analog CCTV cameras , typically RG59 or RG6 coax cable. One of the advantages of AHD over HD-SDI cameras (another HD over coax security camera standard), is that RG59 coax cable can be run long distances without video loss. So far in our experience, installers can reliably use RG6 coax cable up to a max distance of 800 feet for AHD cameras. AHD cameras can also use UTP cable with video baluns to run cable up to 320 Meters / 960 feet with CAT5 cable.
5. What size monitor should I be using?
The correct size monitor is dependent on its use e.g. the number of images to be displayed at any given time, the viewing distance and the available space.
6. What camera housing should I use and at what IP Rating?
Camera housings come in various shapes and sizes. With regard to the correct IP rating protection, this will range from dust and water ingress. This system is governed by a number of European and British standards.
IP55 - Protected against dust - limited ingress.
IP65 - Protection against low pressure jets of water from all directions - limited ingress permitted
7. Can we view the CCTV thru the internet and smart mobiles devices?
Yes. You can view the cctv remotely thru the internet. The AHD DVR has P2P function (Commonly known as "Cloud Base").
8. Can make snapshots, playback, backup thru our mobiles devices?
Yes. The free apps supports IOS and Android with great usable function like snapshots, remote video backup and remote playback.
9. Does it have CMS or Central Monitoring System?
Yes and definitely free. The free CMS can support upto 1000 remote DVR/NVR/IP connections and can view 100 channels. Also support P2P Cloud base connection.
10. Can we combine DVR, IP, NVR at the same thru the CMS?
Yes. Definitely you can, the free CMS works very well, it's very flexible. Just add IP, DNS address, Serial Address for cloud/P2P in the "Create Device Menu". A simple short clicks and its done.
11. What's the name of the apps?
