Many high resolution cameras include advanced night vision capabilities like color night vision. High resolution integrated with spotlight makes it easier for your camera to capture clear and detailed images even in low-light or complete darkness.
Buying High Resolution Security Cameras: Things You Really Need To Consider
When you’re shopping for high resolution security cameras, there are a few factors that you should consider:
The first factor to consider when buying high-resolution security cameras is to evaluate your specific usage scenarios.
Power: High-resolution cameras require a significant amount of power to utilize their advanced features and efficiently process video footage. Evaluate power source options such as Power over Ethernet (PoE), direct electrical connection, or even solar power, depending on the availability and feasibility in your installation area.
Internet: Internet connectivity is crucial for the optimal performance of high-resolution security cameras. The stability and reliability of your network directly impact the quality of video streaming, remote access, and overall functionality of your surveillance system. Evaluate internet connectivity options such as WiFi or Power over Ethernet (PoE) to determine the most suitable solution for your specific scenario.
Audio: Consider the audio capabilities of high-resolution security cameras to enhance their functionality. Look for cameras that offer two-way audio communication, ensuring you can both listen to and speak with individuals in the monitored area.
The cost of a high-resolution security camera can vary greatly depending on the brand and its features. It’s important to determine your budget so you know what price range to look for. For example, if you were shopping for a Reolink security camera, you’d consider these options:
The 2K security camera is typically priced between $50 and $100. At this range, you may find RLC-510WA is a good choice.
The 4K security camera is typically priced between $100 and $200. At this range, you may find RLC-811A is a deserving option.
The detailed video of high resolution cameras requires a lot of data to produce, so you’ll need a sufficient amount of bandwidth through your Internet provider to transmit and store the video feed. Inadequate bandwidth will result in pixelation, lag, and frame drops.
Bandwidth for Liveview and FTP Uploading:
Whether using “Clear” or “Fluent” mode, the bandwidth will equal the bitrate set for the specified mode.
Clear mode: Maximum bitrate equals 8129 kbps.
Fluent mode: Maximum bitrate is 512 kbps.
Stream mode: You determine the maximum bitrate.
Bandwidth for 2.4G/5G WiFi:
Although the wireless signal’s frequency (2.4 GHz or 5 GHz) may impact the signal consistency and strength, it does not impact bandwidth. So what’s the difference between the two frequencies?
- Available Channels:
2.4GHz WiFi has fewer available channels compared to 5GHz WiFi. This can lead to more congestion and interference, especially in densely populated areas or locations with many WiFi devices.
5GHz WiFi offers more available channels, which allows for less interference and congestion, making it suitable for high-density environments.
5GHz WiFi generally offers faster data transfer speeds compared to 2.4GHz WiFi. This is because 5GHz has more bandwidth available for data transmission.
2.4GHz WiFi can be slower, especially in crowded areas with multiple devices competing for limited bandwidth.
2.4GHz WiFi typically has better range and penetration capabilities through walls and obstacles compared to 5GHz WiFi.
5GHz WiFi has a shorter range but can deliver higher speeds over shorter distances.
Most wireless Reolink high resolution security cameras support dual-band WiFi, while PoE cameras don't support.
Encoding format and local storage:
High-resolution security cameras demand considerable storage capacity. H.265 surpasses H.264 in compression efficiency and file size reduction, which is crucial for these high-capacity needs. This improved performance relies on enhanced chips and algorithms, especially in high-resolution security cameras' processors and image processing. Thanks to H.265, security systems can efficiently handle and store massive volumes of video data while maintaining visual quality. Notably, most Reolink cameras employ this H.265 encoding technology.
Moreover, due to the significant storage needs of high-resolution security cameras, we recommend choosing a storage solution with ample capacity. Video recording involves storing both the main stream and sub-streams locally. You can estimate the required storage capacity with a straightforward calculation. Let's use an example for clarity.
Consider the Reolink RLC-1212a, a 12MP camera, which offers a default bitrate of 8192Kbps for the main stream and 768Kbps for the sub-stream.
From these specs, we can calculate the memory usage per minute:
- Main stream: (8192kbps x 60 seconds) / 8 bits = 60 MB per minute
- Sub-stream: (768Kbps x 60 seconds) / 8 bits = 5.625 MB per minute
Combined, these streams consume 65.625 MB per minute.
Given that the main stream and sub-stream are saved concurrently, we can estimate the total duration that can be stored on local storage.
For a battery-powered security camera with a 128GB SD card, the math is: 128 x 1024MB / 65.625 MB x 60 minutes, resulting in roughly 33.27 hours.
For a Network Video Recorder (NVR) with a 2TB hard drive, the calculation is: 2,000 x 1024MB / 65.625 MB x 60 minutes, yielding approximately 516.92 hours.
In light of these numbers, we suggest that for extended recording of high-resolution video, it's ideal to use a Power over Ethernet (PoE) camera linked to an NVR. If you're using a standalone SD card camera, we advise selecting a high-capacity SD card, such as a 128GB or 256GB model.
