Types of Security Cameras: The Essential Guide

Features to Look Out For

Not everyone鈥檚 purpose in having a security camera is quite the same. That鈥檚 why knowing what features to look out for (and what to avoid) based on your specific purpose can help to narrow down the seemingly endless choices. 

Below are the features that you鈥檒l want to consider based on your purpose for having security cameras.

Features to look out for: outdoor use

If you鈥檙e looking to improve your outdoor security, there鈥檚 several features you鈥檒l want to keep an eye out for. First and foremost, an IP rating of IP65 or IP67 is crucial, as this indicates that the camera is waterproof. For a camera to survive outside, it should have an IP rating.

The use for this will depend on whether your property sees a lot of traffic outside it; doorbell cameras may be more useful in this instance, since they can observe only the immediate area around the door or porch.

Features to look out for: indoor use

When it comes to indoor use, wired power may be more useful, since the camera will be within easy access of sockets, USB ports, and so forth. This will avoid the need to recharge or replace batteries. 

Indoor cameras can easily take advantage of Wi-Fi since they are inside, but it鈥檒l also be easier to support an analog camera that鈥檚 hardwired inside. This is a matter of personal preference.

Voice assistants can be a great way to easily sync and control your devices via a virtual assistant, as well as to integrate your security measures into your home鈥檚 overall automation. 

Features to look out for: pet monitoring

The camera will need to support continuous recording; young animals move far too much for motion detection to be of any benefit.

You might want to avoid cameras with voice assistants, since this gives kids ample opportunity to mess around with settings, including the ability to stop recording altogether. Depending on their age, motion detection may prove ineffective for especially lively kids, so you鈥檒l benefit from having the option to switch between motion detection and continuous recording.

Main Types of Security Cameras

Below are the categories most relevant to the average consumer, most commonly used by manufacturers to market their products.

  Wired vs Wireless

  Indoor vs Outdoor

  IP vs PoE vs Wi-Fi vs 4G vs Bluetooth

路   Motion Sensor vs Continuous Recording

路   NVR vs DVR

Wired vs Wireless

The most useful distinction used to define different security cameras is whether they are wired or not. For most homeowners looking for simple security solutions, this will be a major factor in what to look for when buying a home security camera system.

Products to consider:
Wired security camera pick: Ring Indoor Cam. RRP $59.99.
Wireless (Wi-Fi) security camera pick: Arlo Ultra 2 pack. RRP $399.
Wire-free (battery) security camera pick: Reolink Argus 3 Pro. RRP $119.99

Indoor vs Outdoor

Another handy distinction used to differentiate between types of security camera is whether they are purpose built for indoor or outdoor use.

Indoor cameras are not weatherproofed, so using them outside runs the risk of damaging or destroying the camera. Indoor cameras are more likely to be powered through a cable, which makes more sense in an inside setting.

Outdoor cameras are weatherproofed, and usually function via rechargeable or replaceable batteries. Look out for what鈥檚 called an 鈥榚nclosure rating鈥 in the product鈥檚 description, a rating given to products to indicate how waterproof they are. This will either be 鈥業P65鈥 or 鈥業P67鈥.

IP65 gives protection against 鈥榣ow pressure water jets from any direction, as well as condensation and water spray.鈥 This will be adequate for almost all of us.

IP65 outdoor camera pick: Nest Cam (battery). RRP $199.99.
IP67 outdoor camera pick: eufy Solo OutdoorCam C24. RRP $99.99.

IP vs PoE vs Wi-Fi vs 4G vs Bluetooth

The third most common category for security cameras is based on how they connect to the internet.

Almost all security cameras available on the market for the average consumer nowadays are IP cameras鈥擨nternet Protocol cameras. This simply refers to any camera that uses an internet connection to record, store, or send data.

A PoE camera, or Power over Ethernet, is a type of IP camera that鈥檚 most similar to a traditional CCTV camera. It is hardwired, and receives all its power, transmissions, and internet connection through a single ethernet cable.

Wi-Fi security cameras are what most consumers will be looking for because they are the easiest to set up and use in an average home with a wireless broadband hub. They are also by far the most common product on the market. They connect to the internet wirelessly, via Wi-Fi. They are more prone to signal dropouts and slower transfers than a PoE camera.

Similarly, some cameras now support other types of connectivity, including mobile data (4G) and even Bluetooth. These might be useful for someone regularly on the move, or in homes without broadband.

Products to consider:
PoE camera pick: Ring Stick Up Cam Elite. RRP $199.99.
Bluetooth camera pick: Blurams Indoor Security Camera. RRP $49.99.
4G camera pick: Vosker V200. RRP $349.99

Motion Sensor vs. Continuous Recording 

On the other hand, cameras with continuous recording refer to cameras capable of recording constantly, controlled by the user. Though this does use up significantly more memory, it does give the assurance that the camera will never miss a beat.

Additionally, many cameras with motion sensors experience a slight delay of a few seconds between the time the camera notices motion and the time it actually begins to record, so continuous recording is a reliable way to avoid such issues.

Products to consider:
Motion Sensor Camera Pick: Arlo Pro 4. RRP $199.99
Continuous Recording Camera Pick: AlfredCamera.

NVR vs DVR

For those looking for a more traditional surveillance system, perhaps for a business or office-setting, we recommend you get acquainted with DVR and NVR systems.

Before IP cameras completely changed the market, CCTV systems used a Digital Video Recorder (DVR) to process footage. They remain a favorite camera system for business and public spaces often still use them. The camera is hardwired to the DVR using a coaxial cable, so it is a completely wired connection. This makes it quite reliable, and the DVR processes all the footage rather than the camera.

A 鈥榟ybrid DVR鈥, technically known as HVR

A Network Video Recorder (NVR) is usually used with IP cameras because it allows the footage to be saved to a digital format. Unlike DVR, they use wireless technologies to receive and transmit data, but also tend to feature ethernet ports for faster, higher quality uploads than can be achieved with Wi-Fi alone.

Products to consider:
NVR camera pick: Reolink 4K multi-Camera pack with 8-Channel 1TB NVR. RRP $559.99
DVR camera pick: Swann 8-Camera pack with 8-Channel 1TB DVR. RRP $499.99

Other Types of Security Camera

There are many other ways that manufacturers distinguish their products, based primarily on key features. If you are looking for a camera with a specific feature, check out the list below.

路   Solar powered cameras

路   Video doorbells

路   Floodlight cameras

路   Motion sensor cameras

路   Voice assistant cameras

Subscription-free

路   Security camera apps

Solar powered cameras

Increasingly more cameras feature rechargeable batteries as their main power source, and some of these recharge through the sun.

Not only is solar power a great way to be more conscious of minimizing your tech鈥檚 impact on the environment and reduce your bill, but it also makes for additional convenience.

Solar panels in a field harnessing energy from the sun.

A key issue associated with battery-powered security cameras is that there is inevitably a period of downtime when the battery needs to be replaced or recharged. Solar power eliminates this.

Products to consider:
Solar powered camera pick: Reolink Argus 3 Pro. RRP $119.99

Video doorbells

One of the biggest areas of the security camera market to grow in recent years is video doorbells.

Combined with other great features like motion detection, two-way audio, and push notifications, you鈥檒l probably wonder how you ever lived without one once you become a video doorbell convert.

Products to consider:
Video doorbell camera pick: eufy Video Doorbell 2K (battery-powered). RRP $199.99

Floodlight cameras

Products to consider:
Floodlight camera pick: Google Nest Cam with Floodlight. RRP $279.99

Night-vision cameras

Though it is worthwhile having lights to illuminate outdoor areas at nighttime, night vision is a great feature to look out for in a security camera.

The most common type of 鈥榯rue鈥 night vision used in surveillance cameras is infrared (IR) night vision, which relies on built-in IR LED bulbs. These create a visual in virtually no light at all by capturing the invisible light reflected by objects. This forms a clear image in the dark.

Another way to replicate the effect of night vision is to apply low light filters to an image, as is the case with AlfredCamera鈥檚 low light mode. This can enhance features of an otherwise dark image.

Products to consider:
Night-vision camera pick: Lorex 4K Ultra HD Security Camera. RRP $129.99.

Voice Assistant-enabled Cameras

The tech giants (Google, Amazon, and Apple) all have their own sophisticated voice assistants that many security camera manufacturers now support. There isn鈥檛 a great deal of difference between them, albeit the other applications and services they support (generally those that the parent company owns).

You can effectively control all your security cameras from one place just with your voice, including livestreaming, receiving notifications, scheduling, and features like two-way audio.

Products to consider:
Voice assistant-enabled camera pick: Arlo Ultra Pro 2 (Alexa, Google Assistant, IFTTT, Apple HomeKit, SmartThings). RRP $299.99.

Subscription-free cameras

An alarming number of sophisticated security cameras hide their best features, like facial recognition (or even something as basic as cloud storage) behind paywalls. For long-term use, then, you鈥檒l find yourself forking out subscription fees either monthly or annually.

For those who want to forgo additional fees, there are still some great cameras out there that don鈥檛 require subscriptions to effectively run.

Many subscription-free cameras will also feature local storage with SD cards.

Products to consider:
Subscription-free camera pick: eufy SoloCam E40. From $129.99

Security camera apps

The best feature-rich security cameras can be costly. A failsafe way to get around this without sacrificing your home鈥檚 security is to use an old smart device and a security camera app.

AlfredCamera combines the most important features of IP security cameras, like motion detection, continuous recording, and two-way audio, and makes them easier to access than ever. Simply download to an unused smart device, pair with another device, and you have a capable, robust security camera in your hands.

FAQ

What type of security camera is best?

The average consumer looking for a security camera for their home will most likely want an IP camera that can connect to Wi-Fi. These are easy to set up and function seamlessly, as well as giving more options for automation and notifications. Beyond this classification, there is no simple answer. You may, for instance, want a camera with a built-in floodlight because there is no other external lighting around the home. Check out our list to see the main differences between security camera types.

What are the two main types of CCTV cameras?

A traditional analog CCTV camera functions with a DVR, and is not connected to the internet in any way. Internet Protocol (IP) cameras rarely require a DVR or NVR, and are therefore much better suited to homes, while the former are favored in business/office environments for reliability.

What is the most common type of security camera?

The most common type of security camera is a Wi-Fi IP camera.

What is the difference between CCTV and surveillance cameras?

CCTV is an abbreviation of 鈥榗losed-circuit television鈥; in other words, they use coaxial cables to connect to a DVR. This is a traditional security camera with no internet functionality. A 鈥榮urveillance camera鈥 refers to any kind of camera used for surveillance, be it a traditional analog one or an IP camera.

What is the difference between NVR and DVR?

 CCTV systems use a Digital Video Recorder (DVR) to process footage. The camera is connected via coaxial cable. They remain a favorite camera system for business because they are quite reliable. The DVR processes all the footage rather than the camera.

A Network Video Recorder (NVR) is usually used with IP cameras because it allows the footage to be saved to a digital format. Unlike DVR, they use wireless technologies or an ethernet port to receive and transmit data.

Is it better to have wired or wireless security cameras?

A wired security camera (for example, power over ethernet or a traditional analog camera connected via a coaxial cord) can be beneficial because it will be far less likely to experience connection dropouts. It will also upload and process higher quality footage much faster than a wireless camera.

However, a wireless security camera is much easier to set up, more mobile, and possesses more convenient features, like push notifications and alerts.

What is the difference between an indoor and outdoor security camera?

Outdoor security cameras will be weatherproof, meaning they will have received an 鈥榚nclosure rating鈥 (IP65 or IP67). This rating is an assessment of how waterproof the product is. Other differences can include the incorporation of solar panels, visors, and floodlights.

Indoor cameras, on the other hand, won鈥檛 possess an enclosure rating, and will not be suitable for use outside. As such, they are largely powered through a USB cable or other wired connection.
