![]() If a home break-in or car theft happens, and your security cameras fail to capture such events, what's the point of video recordings? ![]() Video loss is really traumatic, especially for the most important video clips. Make Sure There Is No Video Loss When Recording Security Camera Footage So better go for a high definition IP camera or system, especially with optical zoom (for identifying far-away details), when you need to record the CCTV camera footages. We want to get a small handful of cameras for entrances/exits/driveways that will be able to capture high quality detail like license plates and faces (beyond a blob). They work fine for very general surveillance, but provide nothing actionable for the police (can't see faces, license plates). That's one of the most important reasons why you need to ensure that your security cameras can record the details.Īn OP posted a post on Reddit, stating below:Ĭurrently, we've got one analog DVR camera set. You can watch the below clear video captured by RLC-811A security camera (shared by a real user).Ĭlear security camera videos are extremely important for case investigation should any crimes happen (such as car vandalism, harassment, etc.). So you won't miss the important details in your recorded videos. Its 8MP high definition and 5X optical zoom enable you to record all the details you want. You can check this post that explains why a 1080p security camera can read license plates and human faces.Īlso take RLC-811A as an example. So in order to capture what you really want, like license plates or faces from a certain distance, you need at least 2MP Full HD security cameras, or 4MP and even 5MP CCTV cameras with optical zoom function (for identifying details of far-away objects). The result is that no matter how far back CCTV footages go, you won't record what you want. Now assume that you are reviewing the recording videos captured by your security cameras, but you can only see blurry footage without any details you want (such as license plates, peoples' faces). Make Sure Your Security Cameras Can Capture the Details You Want You also need to check the below important points when you buy a security camera & system with enough recording storage space. Enough recording period doesn't mean that you can capture what you want when playing back the recorded videos. Now you can confirm whether a security camera or system can satisfy your video recording period requirements. The security cameras & systems will automatically overwrite the oldest video footage once the storage space runs out. Some of you may ask, "How often do CCTV cameras overwrite materials". You can review the footages and back up the important data you want before the videos gets overwritten once the storage space is full. If you stick to recording continuous videos in high definition, you can install an external hard disk drive via e-SATA for more storage space and longer recording time (up to 12TB with maximum 4TB HDD/port). If you want to extend the recording time of this CCTV security camera system, you can lower the bitrate of the video recording streaming, or try motion detection recording, which will start recording footages only when there are motion events. If you have the same questions as OPs on forums, who asked "How long does the average security camera store footage, or how long is security camera footage kept", hope you've got the answer here. ![]() It means that with the 2 TB built-in HDD in the NVR, the system can support 4 cameras doing 24/7 recording in 8MP Super HD for 6 days. You can also check the CCTV camera storage consumption formula here> Recording Days = (Storage Space (GB) * 1024 2 * 8)/ (Bitrate (kb/s) * 3600 * 24 * Cameras) Take the variables into the formula, and you can see how long the security camera system can record. The bitrate for IP cameras: 8192 kb/s (for 8MP high definition).Reolink RLK8-800B4 security system basics: Let's take Reolink RLK8-800B4 security camera system (with 4 cameras and a built-in 2 TB HDD in the NVR), and RLC-410W standalone IP camera with an SD card slot as examples to show you how long surveillance cameras can record, and how long you can record with 1 TB. Recording Hours = Storage Space (GB) * 1024 2 * 8/Bitrate (kb/s)/3600 Recording Days = (Storage Space (GB) * 1024 2* 8)/ (Bitrate (kb/s) * 3600 * 24 * Cameras)įor Recording Videos in SD Card of a Standalone IP Camera: Through our team's detailed tests, we summarized the below formula to help you calculate how long security cameras can record, thus you can confirm whether a security camera or system with onboard storage space can meet your requirement for video storage.įor Recording Videos in HDD of NVR/DVR Security Camera System:
