Home Security Camera Buying Guide

Shopping for a home security camera can be a tedious task. It’s not really a one model fits all kind of product, so there’s no one camera that works for everyone.


Every situation requires its own camera. Each camera has its own use, range, resolution, day/night capabilities, shape, and connectivity.

This guide will help you buy the right surveillance camera for your home.

4 Questions to Ask Before Buying a Home Security Camera:

  1. Indoor vs. Outdoor – Before buying a camera, you need to decide where is it going to go: inside or outside? This decision affects your overall purchase (more accessories, etc.).
  2. Resolution – How big do you want your picture and coverage to be? For those who want high resolution images, IP (Internet-Protocol) is the way to go, although not at a friendly price. Analog cameras still offer great resolutions at a great price. Most home security cameras are analog, as there is no need for a high resolution.
  3. Lighting – Is there constant lighting where you want to install your surveillance camera? This determines if you need infrared technology or not.
  4. Distance – How far of a distance do you want to focus? This will help you in choosing a lens.

Indoor vs. Outdoor

Not all cameras are created equal. Some are made for indoor use only. If you install those outside, they could get fried when it rains or get ruined by dirt and dust. So security camera manufacturers said “let there be weather-proof cameras.” We have outdoor bullets and domes available, or you could just buy outdoor housing for box cameras.

Resolution for analog cameras is measured in TV lines, ranging from 420 to 700. When it comes to resolution, the higher the TV Lines, the better resolution. If you can, always go for the higher resolution. The only reason to go with lower resolution is if you’re looking to save money, but you won’t be saving much.

IP camera resolution starts at 1.3 megapixels, but is virtually unnecessary for homeowners, (unless you own acres of land). However, there are still advantages for buying IP. There is no limit to how many IP cameras you can connect to the NVR. Another advantage is Power over Ethernet (PoE). Continue Reading The Benefits of IP Security Cameras.

Types of Cameras

Different cameras are used in different situations. For outside home security cameras, choose from vandal-proof bullets or domes, they are ready for outside use. Hidden cameras are placed in the least suspected things like smoke detectors and alarm clocks.

Bullet Cameras

$47 – $984  (Analog)

$458 – $968  (IP)

Bullet cameras are discreet in shape and can be mounted on ceilings and walls. We recommend these for indoor or outdoor use.

Here are our top picks for bullet cameras:

Dome Cameras

$49 – $789  (Analog)

$257 – $2049  (IP)

Dome cameras offer a compact design and great quality imaging. The 3-axis gimbal bracket gives the camera versatility in mounting on any surface. We offer both indoor and outdoor domes.

Here are our top picks for dome cameras:

Box Cameras

$150 – $702  (Analog)

$172 – $1726  (IP)

Box cameras offer high quality images, but cannot operate in complete darkness because they do not come with infrared illumination. Although they are made for indoor use, they could be enclosed in an outdoor housing enclosure and mounted outside.

Here are our top picks for box cameras:

Veilux VS-70CDNRD (Indoor Analog) GeoVision GV-BX120D (Indoor IP)

Hidden Cameras

$73 – $549

Hidden cameras are an ideal way to keep an eye on your house when you are away or for checking up on the babysitter, making sure she is taking care of the kids. We offer many types of hidden cameras, including one in a book, a wall clock, and even a plant.

Here is our top pick for hidden cameras:

The sensor in a surveillance camera needs lighting to capture images. Without lighting, the images would turn out black. We have two solutions available for non-lit or dim-lit areas: infrared illumination and day/night home security cameras.

Infrared Illumination

Cameras with infrared LEDs can be mounted in areas with no lighting at all, and still capture crisp black and white images. The IR LEDs surround the camera and emit a light captured only by the image sensor. Some outdoor cameras come with 25 LEDs and some reach up to 70 LEDs. The more the LEDs, the further the light is shed. So if you have no lighting outside or inside your house, you may want to invest in a camera with LEDs.

This camera’s LEDs allow it to view 70m inside and 60m outside at night:

Day/Night Cameras

Day/Night security cameras are equipped with highly sensitive image sensors. They are able to capture images in areas almost as dark as an overcast night. When reading the specs, look for the lux rating. The lower the lux, the better the camera can record footage without lighting.
Note: Some kind of lighting is still required for these cameras to record video.

This camera has a low lux rating of 0.0001, enabling it to record at night with minimal lighting:


As a homeowner, you probably don’t need to see that far away, especially indoors. Even for those outside, you only need to secure your front and back yards, so a smaller focal length is recommended, as it will give you a wider coverage.

3 Things to Keep in Mind when Looking for a Lens:

Focal Length: The distance between the center of a lens or curved mirror and its focus.

Field of View: To view a wider angle, you need a smaller focal length.

C or CS Mount: Make sure you read the specs of the camera before picking out a lens and make sure the lens has the corresponding mount.

Wireless vs. Wired

$270 – $3933  (Analog)

$520 – $770  (IP)

This has been an ongoing debate between supporters of each side. Wired advocates say wireless is subject to interference from other radio frequencies, not to mention the vast price difference. Wired cameras are cost-effective, have almost no interference, and deliver great picture quality. It does not rely on the network to deliver your video, so you will know it will always be delivered , no matter what.

Promoters of wireless defend that newer products have a higher frequency (5.8 GHz) compared to before (2.4 GHz) and thus are less susceptible to interference. Wireless cameras can be mounted within 10 miles, depending on the receiver. However, you must still connect a power cord to the camera, only the data transmission is wireless.

If you are looking for wireless cameras, check out our wireless cameras section. Or you can take any wired camera and purchase a wireless receiver and transmitter, as you would for a wireless camera, and set them up to create a wireless camera.

For home security cameras, neither cabling or wireless should be an issue since everything is very close to the power outlet.
