AHD and IP are two different technologies created at different times which gives them a large number of differences. AHD, standing for Analogue High Definition, is one of the most up to date analogue technologies using all the analogue methods of video transmission whilst being in high definition. AHD cameras measure resolution in pixels instead of TVL (Television Lines) which some older analogue cameras use. Whereas IP, standing for internet protocol, is the latest technology for CCTV that’s only been around for the last two decades using a different data transmission. They each have the differences, here is the list of comparisons so that you can decide if an analogue system or an IP system is best for you.
It is believed that IP cameras have better resolution than AHD cameras, but this is all dependant on the megapixels of the cameras. What is true, is the quality of the IP image is slightly sharper. This is due to updated technology of the data transmission in an IP system. Analogue cameras turn the video signal into a format that can be received by a television, whereas an IP camera will digitize the video signal creating the difference in the picture quality.
When it comes to storage IP and AHD cameras consume similar amounts of hard drive capacity when the resolution is the same. However, some IP cameras can utilise h.265 compression compared to h.264 used for analogue systems resulting in increased storage space.
Generally, IP systems are tidier than an AHD system because of the cables used. AHD cameras use coaxial cable or also known as RG59 which carries the video and data and a second cable for the power called two core. But you can use something called shotgun cable which has RG59 and two core running parallel which can solve the tidiness problem. IP systems, the cameras are POE (Power Over Ethernet) and just use one cable for the power, video and data which can be either Cat5 or Cat6.
Because IP systems are newer technology, it is generally more expensive than an AHD system. That’s generally because the IP camera’s technology is more up to date and comes with more analytics. But the price in IP technology continues to drop with time.
More engineers are familiar with rg59 shotgun cable because this technology has been around longer. It’s easier to find an engineer to install your AHD system than IP. At Praivo, we make sure that all our engineers are trained to know the ins and outs of both technologies and are ready for all kinds of CCTV installations.
An IP system has more analytics than a standard analogue system. Depending on the camera itself, you can get all different kinds of analytics that can help you in many different situations. An APro AHD system has 3 analytics which the technology is in the DVR. These analytics are Perimeter Intrusion Detection, Line Cross Detection and Stationary Object Detection. Whereas an APro IP system comes with 6 and the technology is held in the camera itself. The extra three analytics are Face Detection, Pedestrian Detection and Cross Counting.
Also, Some camera brands allow for a motorized lens depending on if the camera is analogue or IP. Analogue being a stationary lens and an IP camera being motorized. But if you wanted an analogue and a motorized lens camera check out our AHD varifocal bullets. These cameras come in AHD and IP and all varifocal bullets have a motorized lens that can be controlled from the video recorder or the smartphone app.
In conclusion, there are various differences in each system, it generally depends on the cameras and the cables. But each type is still very effective in different situations so take time to figure out what’s best for you. If you need any more help or have any question, don’t hesitate to call up and ask our product specialist at Praivo.
