![]() Active Deterrent / Alarm Security Cameras – These specialized AI cameras have built-in audio speakers and LED lights so that audio and visual alarms can be triggered when people or cars are detected.The bigger the record resolution, record stream, and record bitrate are, the more disk capacity is taken up in equal times. ![]() We have a bunch of auto-tracking PTZ video demos available here. Auto-Tracking PTZ camera – The Viewtron IP-PTZ-425 is our best selling PTZ IP camera.LPR Camera Systems – License plate capture / automatic number plate recognition is extremely popular for home owners associations, gates communities, and commercial locations that want to monitor a vehicle entrance.AI object detection is much more reliable that video motion detection. These AI camera systems support human and vehicle object detection, as well as facial recognition. AI Security Camera Systems – Some Viewtron IP cameras have built-in AI software, as does our Viewtron NVRs.Viewtron DVRs are also compatible with IP cameras, however, there are no built-in PoE ports and no AI software. They support video resolution up to 4K / 8mp. Viewtron Hybrid BNC DVRs – Viewtron BNC camera DVRs are work with analog CCTV (CVBS), AHD, HD-TVI, and HD-CVI format security cameras.Viewtron NVRs are ONVIF compliant so they also work with 3rd party manufacturer cameras. They have built-in PoE ports and AI software for use with Viewtron AI cameras. Viewtron IP Camera NVRs – Viewtron NVRs are available in 8ch, 16ch, and 32ch models.Watch the above video to see a demo of a home security camera system that uses a Viewtron DVR and Viewtron BNC security cameras. CCTV Camera Pros will develop a bandwidth calculator / data rate calc in the future though. Is this also a bandwidth / data rate calculator? No.That is why we included CIF, D1, and 960H resolutions in the recording resolution setting. Does this hard drive calculator work for analog CCTV DVRs? Yes.That is what is assumed by the calculator. Why doesn’t the calculator take video quality into consideration? We have found that most people use the highest video quality setting.You can watch our H.265 vs H.265+ video comparison here. This is achieved by recognizing when the background is stable / static and moving objects only appear occasionally in the view. H.265+ video quality matches that of H.265 but reduces the amount of disk space and transmission bandwidth that is required. What is H.265+? H.265+ is a video compression / codec that is based on the standard H.265 / High efficiency Video Coding (HEVC) format.You can watch a H.264 vs H.265 video comparison here. Generally, there is twice as much storage required for H.264 compression vs H.265 compression. H.265 is a much newer video format than H.264. It does this without sacrificing video quality. Is H.265 a better video format than H.264? H.265 uses a better compression ratio than H.264, therefore requires less storage capacity.We currently use Seagate Skyhawk hard drives. ![]() Standard hard drives are not recommended for this. Video surveillance requires constant data writing to the hard drive. What type of hard drive does CCTV Camera Pros recommend? We only use surveillance rated storage devices.Hard drive size, HDD size, video storage, data storage, storage space, storage capacity, and storage required all mean the same thing within the context of calculating requirements for security DVR and NVRs. Does hard drive size and storage space mean the same thing? Yes.NOt just for motion detection recording, but also continuous recording. For example, recording in an operating environment that has a lot of movement requires more hard drive space than an area that is very still and does not change. This is because the actual complexity of the video that is recorded is a factor. Please note that all video hard drive calculators are an estimate. How accurate is this video storage calculator? CCTV Camera Pros developed this calculator based on the video compression built into Viewtron DVR and NVRs.Motion Detection Recording: This is an estimation of how much video storage capacity / hard drive space that you will need for motion detection recording. ![]()
