There&#;s no getting past it; security camera systems are used as a precaution when crime occurs or when an accident happens. Whereas many of our customers go years without needing their security cameras, a good number that do are thankful for every detail captured. That is uniquely possible thanks to the camera resolution of their CCTV, which decides how many pixels your high definition security cameras capture and present on a cctv monitor or . It can be an annoying concept to understand, especially when you&#;ve got to decide for your company. However, we&#;ve got you covered with everything you need to know about camera resolution before making your CCTV purchase, starting with what decides the quality.
If you are looking for more details, kindly visit high definition ptz cameras.
What decides camera resolution?
Frame Rate: Frame rate goes hand in hand with camera resolution in that it helps to decide the quality of your video footage. While resolution captures pixels and makes up an image, frame rate decides how many pictures a camera will capture in a period of time to make up the footage. Just like a higher camera resolution for high def security cameras enhances footage quality, so does frame rate by making the video look smoother.
Internal Settings: The settings of your high definition security cameras can determine how effective they are after installation. It might go without saying, but adjusting the camera resolution to your specific preference is crucial to having each work at its best. A1 Security Cameras has previously authored a guide to doing so that is free to anyone needing it.
Lens/Focal Length: The focal length is an aspect of every cctv camera lens that determines how wide of a shot you will ultimately get. The larger the lens, the wider the shot and the more you will ultimately see from a high def security camera, but keep in mind that more detail and movement will in a given shot may affect the resulting video footage. For example, a high pixels IP LPR security camera with a large focal length posted on a road with low traffic will catch every license plate, but the camera resolution might deteriorate. The same high resolution security camera with a smaller focal length lens will have a tighter shot but be more focused.
Local Network: It&#;s no secret that high def security cameras are now regularly watched remotely through cellular phones and computers. That means your local WiFi needs to match the demand of your camera resolution when viewing recordings or streaming from another location with any device is important. A1 Security Cameras offers a free bitrate calculator to help decide if your system needs further hardware or is just right for your highest definition camera.
Sensor Size: The size and type of sensor in your high def security cameras decide how much detail you will ultimately see. Opposite to the lens, the larger the sensor, the narrower visual you will get from each camera.
Aside from what is shown here, it goes without saying that your connected hardware and where you install high def security cameras also matter. For example, you could have the highest definition camera with max settings provide terrible results if there are any obstructions or you&#;re using an old monitor made a decade before your camera. We recommend matching your hardware to the camera resolution you need. Below, you&#;ll find a graph outlining those still in regular use.

Lorex stands out for the sheer number of 4K cameras it offers, and the Lorex 4K Dual-Lens Wi-Fi Camera is the best of them all. It has two 4K lenses that automatically stitches two videos together to create a single, non-distorted, panoramic 180-degree shot. We included sample footage from our Lorex test video down below. The stitched image is so seamless, you can&#;t even tell they&#;re from two different lenses. You won&#;t see this feature on any other cameras on this list.
Remember: 4K is four times sharper than p resolution. And p is currently the industry standard for picture quality. That tells you just how crisp and clear 4K resolution really is.
That said, the Lorex 4K Dual-Lens isn&#;t the best camera for every situation. It&#;s overkill to put it in on a small porch or to make it watch over the stoop of a New York apartment. Trust us, we tried. But that&#;s what we like about Lorex. It has a massive catalog of cameras you can mix and match. You can even combine 4K cameras with 2K and p cameras into one system.
We recommend the Lorex 4K Dual-Lens for these areas:
A dual-lens camera is certainly a first for us. We&#;ve tested 180-degree cameras like the Arlo Ultra (our #3 pick for this list), but most of them use a varifocal lens that creates a fisheye distortion. We didn&#;t see much of that distortion from the Lorex 4K Dual-Lens.
Besides that, Lorex&#;s ruggedness impressed us. You&#;ll see in the video below that we tested our 4K Dual-Lens camera in the snow and it held up like a champ. Here&#;s some info about the 4K Dual-Lens&#; hardware build:
We also loved the fact that it stores videos locally. That&#;s true for most Lorex cameras, but the 4K Dual-Lens can use either the included 32 GB microSD card (which we upgraded to 256 GB) or a compatible Lorex NVR. Fortunately, it paired just fine with the 1 TB D863 Series Lorex NVR that we tested previously (pictured below).
Pro Tip: The Lorex 4K Dual-Lens works with any Lorex Fusion-ready NVR, but make sure to pick one that supports 4K recording. In our experience, a 4K Lorex camera&#;s resolution drops down to p if the NVR isn&#;t 4K-compatible.
The Lorex 4K Dual-Lens was surprisingly easy to install thanks to it being Wi-Fi-capable, although we did use a power drill and screws to mount it. It weighs almost two pounds and we didn&#;t want to risk letting this $250 camera crash to the ground.
At first, the 4K Dual-Lens worked just like any camera we&#;ve tested. It streamed live video (check out the sample video below), recorded clips, and detected our movement.
Then we got to testing the new Lorex app on our iPhone 14 and unlocked some other security features:
There was no shortage of security features on the Lorex 4K Dual-Lens. And it&#;s not the only Lorex camera with those features, as we also saw them from the 4K cameras in the Lorex H Series line. We picked the 4K Dual-Lens for its wall-to-wall viewing angle, but check out the H Series cameras if you need monitoring for a smaller outdoor space.
The price is the biggest kicker. The Lorex 4K Dual-lens Wi-Fi Camera runs $249.99, which is steep compared to other cameras on the market. Only the Arlo Ultra costs more. Here&#;s a side-by-side comparison of 4K camera pricing.
Cost Lorex 4K Dual-Lens Swann PRO-4KMSB Arlo Ultra 2 Nest Cam (battery) Price per camera $249.99 $119.99 $299.99 $179.99 Monthly fee for cloud storage n/a Starts at $2.99 per month Starts at $7.99 Starts at $8 Local storage MicroSD card or NVR DVR or NVR Arlo SmartHub with microSD card or USB drive NoneDespite Lorex&#;s higher cost, we still like this camera brand because it doesn&#;t require a monthly subscription. That&#;s an easy $80 savings per year compared to the Nest Cams. (We&#;ll unpack Nest Cam&#;s subscription pricing below.)
The Lorex 4K Dual-Lens stores video in the included 32 GB microSD card, but you can swap it for a higher-capacity microSD card up to 256 GB. We recommend it. We did that and were able to store more than a week&#;s worth of videos.
Alternatively, if you&#;re buying multiple cameras, you can invest in a 1 or 2 TB NVR. In our experience, a 1 TB NVR can hold up to 10 days of rolling recordings from four 4K cameras. Just make sure all your cameras are compatible with the NVR and that the NVR is 4K-capable.
Bottom Line: If you can afford the $250 price tag, we recommend going with the Lorex 4K Dual-lens Wi-Fi camera. It offers a wide but non-distorted field of view, great hardware build, local storage options, and a built-in siren and lights for deterring burglars. We just don&#;t recommend it if you live in an apartment.

Swann&#;s product catalog isn&#;t as large as Lorex, but it does have some interesting options like the PRO-4KMSB thermal-sensing camera we tested.
The PRO-4KMSB uses infrared-powered night vision to see up to 150 feet in total darkness. That&#;s impressive because our Lorex 4K Dual-Lens could see only up to 32 feet. Additionally, the PRO-4KMSB uses infrared-powered motion detection to reliably detect human, animal, and vehicle movement. That&#;s the same technology used by motion sensors in security systems. It&#;s primitive compared to the A.I. detection in the Lorex 4K Dual-Lens, but it tends to be more accurate as it senses body heat.
We tested another 4K camera from Swann &#; the NHD-885MSFB Spotlight IP Security Camera. It&#;s pretty much the same camera, but with a built-in spotlight. This means it can scare away burglars and see in full color at night instead of black and white. However, it sacrifices the night vision range &#; instead of the 150 feet range with the PRO-4KMSB, we got only about 115 feet of night vision from the NHD-885MSFB.
FYI: Built-in spotlights have become a standard feature in many security cameras. Lights are effective crime deterrents, which is why cameras like the Ring Spotlight Cam we reviewed and the Nest Cam with Floodlight are excellent for outdoor security.
The Swann cameras we tested were not as flashy as the Lorex 4K Dual-Lens or the Arlo Ultra 2. They didn&#;t have A.I. detection. However, we knew that we could count on Swann if we needed a versatile but affordable camera system. Here&#;s what we got for our $600 budget:
That&#;s four cameras and a DVR for less than the cost of a two-camera pack Arlo Ultra 2 bundle ($599.99).
The two 4K cameras from Swann stood guard outside our house. And because we wanted to save money and didn&#;t need 4K cameras inside our home, we went with p HD cameras for indoor use. That&#;s one of the best things about a Swann system. There are tons of camera options and many of them work together to create a camera system tailored to your home.
Pro Tip: You can buy Swann camera sets with at least four cameras and a DVR starting at around $300, but you can also customize your system. A DVR ties the system together. We got a refurbished eight-channel DVR for $150, 50-percent off the MSRP.
Unlike the Wi-Fi capable Lorex 4K Dual-Lens, both the 4K cameras we got from Swann required wiring. Each came with a 60-foot BNC cable. If you know anything about us, we&#;re not big fans of that type of wire in security camera installation. It&#;s difficult to work with because it&#;s thick and stiff, making it hard to bend around corners. We much prefer Ethernet cables.
After the two-hour installation, we began testing the cameras. There honestly wasn&#;t much to test, but we had fun pushing the limits of their accuracy in detecting movement. Again, both 4K Swann cameras use thermal sensing a.k.a. PIR motion detection. That means they can be triggered only when the moving object emits a heat signature.
Here are some tests we ran and how the cameras responded:
As you can see, these cams were pretty accurate. We also loved that the NHD-885MSFB&#;s spotlight turned on everytime it detected a moving heat source. That&#;s a great way to surprise intruders, and hopefully get them to scram. It also features two-way audio so you can speak directly to visitors or package thieves.

Pro Tip: Not all Swann cameras and DVRs are compatible with cloud backup. In fact, our 4K Swann cameras were not supported. If you really want cloud backup, though, we learned that you can backup recorded DVR videos to a Dropbox account.
On the downside, both Swann 4K cameras offer a narrow viewing angle. The PRO-4KMSB gave us a 90-degree field of view while the NHD-885MSFB gave us a slightly wider but still narrow 93 degrees. Remember, the Lorex 4K Dual-Lens has a 180-degree field of view that simply can&#;t be beat.
But did we really expect Swann to do as well as Lorex? No, especially not at Swann&#;s cheaper price point.
Swann Product Price PRO-4KMSB (4K outdoor camera) $119.99 NHD-885MSFB (4K outdoor camera with spotlight) $169.99 PRO-MSB (p indoor camera) $59.99 each Refurbished SRDVR-H (4K-capable 8-channel DVR) $149.99And just like with Lorex, we didn&#;t pay a monthly fee with Swann. All the recordings went straight to the 2 TB DVR. We kept all four of our Swann cameras running and recording for three weeks straight and they used up only 80-percent of that storage space.
Another great thing about Swann is that there is an optional cloud storage subscription. Prices start for $2.99 per month with a 90-day free trial. That&#;s very generous when compared to other brands in the market.
Bottom Line: Swann offers great motion detection and crystal clear image quality, but we don&#;t love that it&#;s a hardwired camera system. If you want a simpler setup with just as high a resolution, stick with Lorex.

Arlo is one of our favorite brands of battery-powered security cameras, and it has just the perfect 4K battery-powered cameras. There are two, actually &#; the Arlo Ultra and Arlo Ultra 2. They have some differences in how they connect to the internet, but they offer the same features and specs.
The Arlo Ultra cameras have impressive video quality thanks to their high dynamic range (HDR). Essentially, this feature digitally enhances the lighting to balance out dark and bright areas to get rid of excessive glare and shadows. The sun sets facing our backyard where we placed the Arlo Ultra and the HDR really helped. There wasn&#;t a lot of glare, unlike with the Swann cameras from earlier.
On top of that, the Arlo Ultra has a 180-degree maximum field of view. It&#;s not dual-lens like the Lorex 4K camera we tested. It uses a varifocal lens instead, and you can actually adjust the viewing angle to 120, 155, or 180 degrees. 180 degrees was too heavily distorted though. It really curved the horizon and made our faces look funny. On the other hand, 120 degrees was too narrow. We recommend sticking to 155 degrees.
There are a few things that set the Arlo Ultra apart from the other 4K cameras we tested.
For starters, it runs on battery (or sunlight if you buy the $60 Arlo solar panel). That means you can set it up pretty much anywhere without having to look for an outlet to plug it into. The setup took us just 10 minutes and no wiring was involved. (Remember our two-hour Swann setup?)
That varifocal lens also makes the Arlo Ultra versatile; although again, we recommend using only the 155-degree setting.
What really impressed us about the Arlo Ultra was the smart motion detection powered by A.I. We saw the same feature from the Lorex 4K Dual-Lens, but Arlo&#;s A.I. was just more reliable. It accurately detected and distinguished humans, animals, vehicles, and packages every time. And with the help of Arlo&#;s app, we were able to use that to customize how it protects our home. More on that below.
FYI: The Arlo Ultra fits a powerful spotlight within its small frame. It stands about four inches tall (fits in the palm of our hands) but features a 400-lumen spotlight. It was more than bright enough to illuminate our 25-by-35 feet backyard.
Let&#;s start with the bad news: Arlo requires a cloud subscription to use its A.I. features. And the subscription options aren&#;t that cheap. They start at $7.99 per month for each camera. To put that in perspective, our #4 pick Nest charges $8 per month to cover unlimited cameras. We don&#;t think Arlo is worth using without a subscription, as you wouldn&#;t be able to access A.I. detection, cloud recording, and its other useful features.

So we signed up for an Arlo Secure plan after setting up the Arlo Ultra and unlocked these perks:
Those are nice perks, but Arlo&#;s ability to detect and deter burglars and package thieves comes mainly from its built-in spotlight. You can manually activate it &#; for example, while watching a trespasser in real-time. But you can also set it up to turn on automatically when the camera detects movement. We went with the latter.
Additionally, we liked that there&#;s an option to customize the light behavior. Our Lorex 4K Dual-Lens and the Swann NHD-885MSFB just turn on their spotlights when they detect movement. With Arlo, we got to set the spotlight to pulsate (brighten and dim slowly) or flash (turn on and off in quick succession). It won&#;t just take a burglar by surprise; it will disorient them.
Pro Tip: Aside from putting up security cameras, installing adequate lighting is one of the ways you can protect your home against home invasion and break-ins. Spotlight-equipped cameras like the Arlo Ultra hit two birds with one stone.
Now comes the tough pill to swallow: The Arlo Ultra 2 is priced $299.99, and that&#;s just for the camera. It also requires a SmartHub, a wireless base station that connects up to five Arlo cameras to the internet. And if purchased separately, it costs $149.99.
Arlo offers bundles, but the minimum bundle is for two Arlo Ultra 2s and a SmartHub for $599.99. That saves you about $150 compared to buying the components individually, but Arlo&#;s pricing is still more expensive compared to Swann&#;s.
Arlo Products Price Arlo Ultra 2 (2-camera pack) $599.99 Arlo Ultra 2 (3-camera pack) $899.98 Arlo Ultra 2 (4-camera pack) $1,299.98 Arlo Ultra 2 add-on camera $299.99 Arlo SmartHub $149.99 Arlo Solar Panel $59.99You also have to factor in the monthly fee. It&#;s not absolutely required, but we highly recommend getting a subscription. The price is $7.99 per month per camera. That gets you all the features we listed above and 30 days of cloud storage. If you have more than one camera though, there&#;s a $12.99 plan that covers unlimited cameras installed in the same location.
Bottom Line: The Arlo Ultra is the most expensive option on this list &#; by far. So if you like Arlo, we&#;d recommend going with the more affordable Arlo Pro line of 2K cameras and Arlo Essential line of p cameras. Check them out in our Arlo review to see which one suits you best.

The Nest Cam (wired, indoor) is technically not a 4K camera, but it comes really close. It has a 4K image sensor and HDR, just like the Arlo Ultra. While testing the Nest Cam, we found those technologies work together to capture crisp, life-like videos. The 4K image sensor was great for capturing tiny details, while the HDR balanced high-contrast lighting.
Keep in mind that 4K indoor cameras are hard to come by. Manufacturers usually only release 4K outdoor cameras &#; which is why we selected the Nest Cam (indoor) as the next best alternative. Head over to our Nest Cam review &#; you&#;ll see there that the video quality of the Nest Cam isn&#;t too far off from the 4K cameras we listed here.
FYI: Nest also offers a battery-powered outdoor counterpart for the indoor only Nest Cam (wired). It offers most of the same features but it&#;s weather-resistant and it runs on batteries. See our Nest Cam (battery) review for more information.
What&#;s even harder to find than a 4K indoor camera? A 4K indoor camera with facial recognition. The Nest Cam (indoor) comes pretty close to a 4K camera, and it does have facial recognition.
Much like the Arlo Ultra, the Nest Cam (indoor) required us to sign up for a subscription to access its best features. Facial recognition, or Familiar Face Alerts as Nest calls it, comes with the $8 per month Nest Aware subscription.
Here&#;s how Familiar Face Alerts worked for us:
We were so eager to test out Familiar Face alerts once we got our Nest Cam (indoor). Fortunately, the setup took us only five minutes &#; as expected from one of the best indoor cameras. We simply plugged in the camera and paired it with our app.
It takes time to fine-tune Familiar Face Alerts. It was inaccurate at first. Three days in and it was still making a lot of mistakes. We&#;d say the best way to teach the Nest Cam how a person looks is to have it capture them at least five different times. It also helps if they&#;re captured in different lightings and angles, as that really helps the A.I. learn their facial features. The accuracy shot up to about 90-percent when we started doing that.
So, did Familiar Face Alerts really improve the Nest Cam&#;s crime-fighting ability? Well, it was a flashy feature for sure. It helped us manage notifications and know when to check our live streams. But as a crime-deterrent, it does very little to help. The same was true for the camera&#;s person, animal, and package detection.
We&#;d also like to point out that the Nest Cam (indoor) doesn&#;t really play loud sounds to deter burglars. The now-discontinued Nest Cam IQ Indoor had that feature, and we&#;re not sure why Google removed it from the current Nest Cams. At least there&#;s two-way audio, though! It was loud enough to fill our living room. But as far as potentially scaring burglars away, that was the Nest Cam&#;s only feature.
The Nest Cam (indoor) is just one of the three cameras from Nest Cam. There&#;s also the Nest Cam (battery) and Nest Cam with floodlight. Prices range from $99 to $279.99, which is a little expensive compared to prices from Ring, one of Nest Cam&#;s fiercest rivals.
Security Camera Options Nest Cam Ring Plug-in indoor camera Nest Cam (indoor) &#; $99.99 Ring Indoor Cam &#; $59.99 Battery-powered outdoor camera Nest Cam (battery) &#; $179.99 Ring Stick Up Cam Battery &#; $99.99 Wired outdoor camera with floodlight Nest Cam with floodlight &#; $279.99 Ring Floodlight Cam Wired Plus &#; $199.99On the other hand, Nest&#;s cloud subscription is slightly cheaper than Ring&#;s. It costs $8 per month to provide 30 days of video history to any Nest Cam in your home. A Ring Protect subscription for unlimited Ring cameras costs $10 per month, but that gives you 180 days of video history.
One final note &#; although Nest Cams aren&#;t professionally monitored like the Deep Sentinel cameras we reviewed, signing up for Nest Aware gave us access to e911 via the Google Home app. In case of an emergency, e911 will connect your call to emergency services closest to your home as opposed to your real-time location. We didn&#;t try it out as we didn&#;t want to make a false 911 call, but during setup, our app made us pin our home address.
