You know a security camera‘s line of sight is important, right? I hope so. Learning how far a onvif security camera can see will help you better set up your home surveillance systems and leave no blind spots.

You’re about to learn what determines a security cameras’ range limit (including at night) and get some recommendations of the best long range outdoor security cameras for your security needs. So let’s get started.

Influence Factors of ONVIF Security Camera

To cut to the chase, we’ll first discuss some of the questions you concern about most, like: How far of a range can color night vision security camera see? What’s the range, in meters, of security cameras’ line of sight? Or how much can security cameras see? In fact, the security camera range distance is mainly affected by the following factors.

Factor 1: Focal Length of ONVIF Compatible Camera

The focal length, or the size of security camera lenses, is the NO.1 factor determining how far ip security cameras can see. It is measured in mm and can be classified into fixed focal length (found in fixed lens security cameras ) and variable focal length (available among vari-focal security cameras ).

The smaller the focal length, the wide field of view your onvif security camera can see. Likewise, a larger focal length makes for a narrower field of view of your surveillance cameras. According to the experience of security camera installers, if you expect your security camera to see within 40 feet, a 4.0 fixed lens security camera is enough to do the trick.

The ptz security cameras or zoom security cameras, on the other hand, are more suitable if the viewing area is far away (beyond 40 feet) from the location where cameras are installed.

Factor 2: Home Surveillance systems Resolution

It would make no sense if your security cameras just see something but make out no details. So, instead of asking how far a security camera can see (at night), it is wiser to focus on how far security cameras can see clearly with visible details.

And that’s where the resolution of your security cameras come into play. With the price of HD security cameras becoming much affordable, you can employ the 4MP, 5MP and even 4K security camera systems for video surveillance with vivid details.

Factor 3: Location

The location where you place your security cameras can also affect how far a surveillance camera can see. Let me explain further: for the wireless security cameras, bricks, concrete floors, walls and even outdoor large trees between the camera and the monitoring site can be weaken the signal strength, thus influencing how far your security cameras can see.

Factor 4: Quality of ONVIF Surveillance Camera

The camera quality also matters when it comes to determining how far of a range retail security cameras can see, as not all surveillance cameras are created equally well even they are tagged with the same field of view.

The top security camera brands with a large customer base, are far more reliable than those unknown camera sellers.

And you’ll learn the lesson especially when you need technical support from the camera sellers. Renowned camera brands usually offer sound after-sales service which the little-known brands fail to do so.

Deeper Learning: Can security cameras see in the dark? And how far can a security camera see at night?

Well, the security cameras with night vision capability can absolutely see around in the dark. As for how far a security security camera can see at night, on top of the factors listed above, it is also affected by the number and type of LEDs, lux rating, if the camera is featured with 3D-DNR function and infrared technology. Normally, you can learn the IR distance of security cameras from product specifications.

What to Do If You Want to Monitor Places at a Distance

So, if you need to keep tabs on a site from a distance, below are some feasible tips to serve your purpose:

ㆍChoose the varifocal lens security cameras which can see a larger field of view. You can zoom in to identity visible details at a distance without degrading the image quality.

ㆍHigher resolution security cameras, like 5MP and 4K ones, can increase the odds to deliver usable images and videos from a distance.

ㆍIf you intend to buy a wireless security camera, make sure there are few blocks between the camera and the monitoring site.

ㆍGo for the security cameras from reputable brands to avoid possible disputes and unnecessary trouble later.

ㆍEnsure that your security cameras can also see far enough with recognizable details at night.
