HD security cameras with 1080p video resolution have become very affordable and available over the last six months. People shopping for new video surveillance systems and those looking to replace existing CCTV cameras should consider HD cameras. With the price difference between CCTV and AHD being small and the resolution difference being so big, the team at CCTV Camera Pros is recommending HD in almost all cases. This article will compare 1080p video resolution from an AHD (analog high definition) camera to the resolution of a traditional analog CCTV camera.
The above image was taken from still frames in the video that you can see below. You can click on the image to see the full size capture. The image on the left was captured with a 960H resolution (960 x 480 pixels) outdoor CCTV camera – the BIPRO-S600VF12. The image on the right was captured with a 1080p resolution (1920 x 1280 pixels) AHD CCTV camera – the AHD-AD24H. In both cases, the image was displayed on a 1080p monitor in full screen. The BIPRO-S600VF12 has been a best seller for the past 3 years and holds up very well in outdoor installations. However, you can see that even the best CCTV cameras can not compete with the video quality that you get from the latest HD cameras.
HD Security Cameras Better for Face Recognition
When it comes to identifying details in the image, you can see that the high definition camera makes a big difference. This close up of the subjects face shows that facial recognition is achievable with the HD camera, but the analog camera falls short because of the low resolution.
HD Surveillance vs CCTV Surveillance Video
When you watch the above video, adjust the YouTube player resolution to 1080p if you are watching on a desktop PC (which is recommended), then expand the player to full screen mode. The video footage was captured by connecting both cameras to an iDVR-PRO16M CCTV / HD surveillance DVR which works with AHD cameras (720p and 1080p) and analog CCTV cameras. This type of hybrid DVR is very handy for users than want to use both camera types. It is perfect for users that have existing analog cameras that they still want to use, but want to add HD cameras now and in the future to replace the existing cameras.
Upgrading from CCTV to HD Cameras
If you have an existing CCTV system and want to upgrade, you should check out this guide on how to upgrade CCTV system to an HD surveillance system. Owners can leverage their existing RG59 coax cable or CAT-5 cable with video baluns for 1080p AHD cameras. You can also contact me if you have any questions. I can be reached at email@example.com.
