4K Security Camera Systems Video Surveillance Service & Installation
4K security cameras are known for producing the best quality image with unmatched clarity. These cameras support 8 million pixels per unique image and capture every important detail in high-definition. They are also known as 8mp security cameras because they offer UHD video surveillance at 3840×2160 pixel resolution.
What is a 4K HD Security Camera?
4K security cameras provide a sharp display of recorded images. You can see the details better even when zooming in, which proves helpful in uncertain conditions such as crime or vandalism. The frame rate of a 4K security camera is high, which means that fast-moving objects also get a good view.
4K HD or 4K High-Definition cameras, as the name signifies, can provide up to four times higher resolution than a standard HD 1080p resolution camera. They are known in the industry for producing the best quality and clarity of any image. 4K HD is based on square pixels, so that 4K HD videos can be shown on computer monitors and HDTV screens.
4K Camera Definition & Picture Quality
4K surveillance cameras offer high-definition image quality at 3840×2160 resolution with over 8 million pixels. For the most part, there are two resolution standards – 3840×2160 and 4096×2160. However, when people talk about high definition surveillance cameras in the security industry, they often refer to the ones with 3840×2160 resolution. 4K Cameras offer more detailed picture quality that allows better visibility.
4K HD vs. 1080p
Over the past few years, the 1080p resolution has gained popularity, driven mainly by the consumer electrical market. 1080p resolution is still a consumer standard but has taken a hit due to the rise of 4K HD cameras. 1080p provides up to five times higher resolution than standard analog video and has better color fidelity with a 16:9 format. However, the 1080p camera market has declined, as 4K cameras offer four times higher resolution than standard 1080p. Both can be shown on either a computer monitor or an HDTV screen. 1080p is cheaper than the 4K cameras in terms of costs, but 4K cameras capture a larger space.

The audio capability of 4K cameras is unique from other security cameras. These cameras support a built-in microphone with noise filters, making the sound quality clear.
Night Vision & Lighting

Infrared LEDs support night vision capabilities with distances up to 200 feet. Allowing the security cameras to capture videos clearly, both during the day and at night. Lighting is also integrated with the security camera system, making it possible to throw light on individuals entering secured areas of the facility during the night. This helps capture the video of the incident, which could provide evidence or deter future crime. Some of the cameras support color night vision, which offers colored images that are more accurate and visible than black and white photos. As we know, most crimes and intrusions happen at night, so this feature is critical to protect your property after hours.
Wide view angle

4K security cameras support an ultra-field of view, up to 110 degrees, that can help you see the whole secured area clearly. Due to its wide coverage, monitoring the activities becomes a lot easier under one screen than multiple screens. The lens also has an auto-image correction, which decreases the fish-eye effect you often get with security cameras. The camera placement at the right angle to accurately cover the wide field of view is critical.
Two-way communication

4K security cameras support two-way communication that eases the interaction with your visitors. You can hear and speak to visitors without interruption with the help of noise cancellation technologies.
Motion Detection

Motion detection is an essential feature of security cameras that can notify or alert you when it identifies something suspicious going on around the property. The technology works when there is an unexpected movement within the frame. This movement triggers your camera to record the incident immediately.
Weatherproof

Since most 4K security cameras are installed outdoors, weatherproofing is very important. This makes the camera more durable to fight against adverse weather conditions, intrusions, and other harmful external forces.
Vandal-resistant

4K security cameras are vandal resistant to protect the camera from vandalism damage.
Limitations of 4k security cameras
4K security cameras can have some cons as it relates to cost. While detailed image viewing is not a requirement for every business, Full HD security cameras can get the job done and are relatively cheaper opposed to 4K cameras. However, when it comes to identifying individuals in a particular situation, 4K security cameras work the best.
HD Security Camera Placements
The placement of security cameras is critical to businesses. HD Security cameras are typically placed in the corners of a given building. They are primarily used to secure parking lots, lobbies, docks, emergency exits, first-floor glass windows, break areas, halls, laboratories, warehouses, shops, etc.
These cameras can also cover areas like cash counters, entry gates, and electrical/data rooms. Cameras are placed strategically, such that people cannot move from one place to another without being captured and recorded. This is a term called trap surveillance. It is mainly used in large commercial buildings. Techniques like wide-angle lenses and panoramic views help reduce the number of camera installations in one area. This way, the premises can remain protected under one umbrella.
The best height for installing a security camera is typically 10 feet above the ground. This height prevents intruders from damaging the camera before committing a crime. If you place a camera at one of the exterior doors or windows, the bright sunlight may limit the camera’s view. Cameras use techniques such as auto iris to prevent such obstacles. Contact a professional security consultant like Umbrella Security Systems if you want to install security cameras in your facility. We have 20 years of experience and knowledge to guide you on the right track, from planning and designing all the way to the camera installation at your facility.
