Why You Shouldn't Buy Cheap Security Cameras

If you are shopping for security cameras for your home or business you may wonder why there are large price differences between camera models that seem to have the same specifications but are sold by different companies. Truth be told, prices often reflect the quality of the product you are buying. As the saying goes, “You get what you pay for.” It is important for savvy shoppers to know why it’s not recommended to cut corners when shopping for a security camera system. Is saving a couple of hundred dollars worth the thousands that you can save by investing in quality surveillance cameras?

Below we list the features that industry experts at CCTV Camera World recommend considering when comparing surveillance products. These features provide more insight about the cost difference between professional vs cheap security cameras.

Quality of Image Sensors

With cheap security cameras come cheap image sensors. Manufacturers like to cut costs wherever possible. Image sensors are one of the most expensive parts of a camera, and the main component that determines the video quality of a camera. Cameras that use poor quality image sensors do not produce clear video.

For example, a camera made with a low quality sensor may claim to have 4K resolution but will fall short when its video quality is compared with video from a real 4K security camera. An inexpensive 4K camera that costs $100 from a low-cost vendor will never come close in providing the kind of clarity provided by a 4K security camera that costs $200 from a reputable manufacturer. 

Many low cost surveillance cameras have blurry video when compared to higher quality products. Always look for actual video samples, like the ones featured on CCTV Camera World. Don’t fall for stock photos that do not demonstrate actual performance of the camera you are considering to purchase.

How to compare security cameras?

Digital zoom is a great way to measure the quality of the image sensor inside the camera that captures video. Using digital zoom is common for gathering detail on a face, license plate, or vehicle. Digital zoom works by magnifying a selected part of the field of view in the video to see minute detail. When using digital zoom some pixelation can be expected depending on the resolution of the camera and the quality of the sensor. Low-quality image sensors fail to provide pixelation-free digital zoom when compared with high-quality sensors.

To illustrate the difference, below is an actual example comparing one of CCTV Camera World’s 4K Security Cameras (model IPC4K18)  to a 4K camera from an Amazon vendor. When we use digital zoom to magnify license plates on cars parked 30ft away the difference in video clarity is apparent. The image provided by the cheaper camera on the right becomes blurry making it difficult to interpret the license plate numbers.

The difference in image quality between the two cameras is more pronounced when attempting to see farther away. We explain this in further detail in the video below.

Why You Shouldn't Buy Cheap 4K Security Cameras






Night Time Video Quality

All cameras with built-in infrared for night vision will appear to have fuzzy, grainy or unclear video at night. High quality security cameras feature technology to detect and correct noisy video. Noise Reduction Technology, also called 3DNR, uses image processing to enhance video production at night. 

Inexpensive or "cheapo" cameras claim to have noise reduction features but do not perform. Noise reduction is  important when trying to see detail at a distance in black and white mode at night. With poor quality noise reduction it is almost impossible to make out a face or writing on a sign at a distance.

In our comparison we found the “cheapo” Amazon Cameras to have poor image production by the sensor compounded by poor noise reduction. You can see the difference for yourself below.

Encoding and Codecs - Video Compression Artifacts

Low-cost cameras also means that not enough money went into research and development. This leads to software that has a poor design and introduces issues. One of the major issues with low-end video products is video artifacts. Video requires encoding to be done by a chip on the camera. Low cost chips with poor video encoding power and poorly implemented video encoding algorithms cause video artifacts. Video artifacts are frustrating streaks, blotches, or weird pixelations in video. Sometimes it looks like a pixel dance as shown in the video comparison above.

Video artifacts are common in the video produced by cheap cameras, especially in high resolution cameras like 4K. The video encoder inside the camera cannot handle the amount of power needed to encode 4K resolution video properly.

Artifacts prevent identification of intruders, and can render video clips useless. It’s hard to see when video distorts, blurs, or does not record well. What good is a camera if it lacks the ability to record footage without video artifacts?

Durability and Longevity

Cost cutting measures related to a camera’s physical construction are also common in the production of a low-cost camera. Unfortunately most frugal buyers are unaware that cost cutting includes poor physical design of the camera, low-grade materials, poor weather sealing, and cheap solder.

An outdoor surveillance camera should be constructed with aluminum or plastic that is durable enough to withstand the elements. Particular attention is paid so that water is never pooling on the joints or gaps that are reinforced with a rubber gasket. Low quality aluminum that is not properly powder coated is known to rust over a short time. Similarly, cheap plastic camera casings crack outdoors while strong ABS plastic casings can outperform metal encased cameras.

Weather proofing is another way to cheap out when producing security cameras. By industry standards an outdoor security camera should have an Ingress Protection or IP rating of 66 or higher.

Although low-cost cameras may have an IP rating they are often misleading. When poorly thought out camera design that fails to create a watershed on the camera is combined with low quality rubber gaskets to keep the moisture out, water can easily find its way in. Moisture can condensate to fog the camera lens, or pool inside and damage the internal electronics.

Commonly no one thinks about the quality of the solder that is used on the circuit board inside. Soldering that goes into creating the circuit boards inside is another way to cut costs. High quality soldering helps to create connections that will not break over time.  Low-cost cameras have poor solder material that will degrade quickly over time or bubble in hot temperatures. Cutting corners for soldering means that the product will have a higher rate of failure when exposed to hot temperatures outside.

Warranty

When you see something that's too good to be true, it usually is. Vendors claiming free warranties in excess of 2 years on surveillance camera products are riddled with exclusions. Product warranties are limited warranties against manufacturing defects and it is normal to have exclusions for misuse, tampering, modification, incorrect voltage or surge, lightning, and acts of God. When no sign of these exclusions is present, warranty claims are frequently denied by some vendors. 

It is important to realize the reasoning behind why warranties beyond 2 years are too good to be true. New camera models are developed every 2 years, while older models are phased out and  so is their inventory for parts to repair products. If there are no parts to fix an item that is more than 2 years old, nor are there equivalent products to replace the malfunctioning item, how is the warranty claim going to be filled?

Tech Support

Security products have become complicated electronics. Having good quality technical support is important to learn how to use what you purchased. Manuals with poor English are common with cheap products as there is little investment made by those companies in creating modern instructional material that is easy to follow. 

Surveillance systems do require troubleshooting as there are other components like cabling, DVR recorders, and power supplies which can cause issues in video quality. Having access to qualified and experienced technical support is crucial to resolve problems. Most online sellers are driven by price alone to sell the cheapest camera or system to entice buyers. However, when help is needed, buyers are met with long hold times, voicemail systems,, email response times of 48 hours if they are lucky, or completely clueless tech support representatives.

Unfortunately, when buying cheap security cameras you should not expect anything better than third-class support from a representative in a Third World Country.

At CCTV Camera World we get more calls for support each day from buyers who have not even purchased from us. They are desperate individuals looking for technical help with a cheap security camera system they purchased on Amazon, Ali Express, Ebay or the like, and the product seller failed to provide support or even easy access to a support department by email or phone.

If you're reading this article that you found us on the web because we spend the majority of our time writing how-to guides or tutorial videos to simplify the use of our products. Written manuals are a thing of the past and the best way to learn is by reading up-to-date guides in our knowledge base. If you have a technical question, feel free to submit a tech support ticket and we usually respond in less than 2 hours during business hours. If it is a quick question, feel free to give us a call.

Take away

We hope this guide serves to provide useful information to a buyer whose shopping online for security cameras and evaluating products based on price alone. In the security camera industry, there are hundreds of vendors to choose from. Choosing the vendor that's a fit for you depends on how much you want to spend, the quality you are looking for, and the cost and quality of after-sales technical support provided by the vendor.

A couple of days before we wrote this post, a customer called in and told us a great story about how he learned his lesson that you get what you pay for. He recounted several years back he bought brake pads with a lifetime warranty for his pickup truck. His brakes faded in 6 months, which never happened to him before with aftermarket brakes from a different manufacturer. Usually his brake pads last him 2 years. He went back to the shop that sold him the brake pads and they said sure we can replace those brakes, there will be a $80 charge for each axle. That meant every 6 months, he would have to spend $160 to get the lifetime warranty.

graduated from New York University with a degree in Chemistry and Computer Science. His vision to make the CCTV buying process transparent made CCTV Camera World the leader in the surveillance equipment industry to provide actual video samples for customers to watch about the capability of the camera they would like to purchase. In addition, his approach to simplifying technical support shaped the way we provide technical support in to easy to follow guides with tutorial videos. When he is not writing, coding, or recording tutorial videos, Ray loves to spend time with his family.
