Dome cameras are one of the most common types found in businesses. These cameras get their name from their rounded, dome-shaped housing. The dome design makes it difficult for people to tell which direction the camera is actually pointing, which some business owners prefer for deterrence purposes. Dome cameras work well for indoor spaces like retail stores, offices, and warehouses. They typically mount to ceilings and blend in with building architecture. Many dome cameras include infrared technology for nighttime recording.

Bullet cameras have a long, cylindrical shape that resembles a bullet or spotlight. These cameras are highly visible and are often chosen when businesses want obvious security presence. Bullet cameras work well for outdoor monitoring because their shape sheds water and resists weather damage. They mount easily to walls or poles and can cover long distances. Many bullet cameras include zoom capabilities, allowing operators to focus on distant areas. Bullet cameras are frequently used in parking lots, building entrances, and perimeter monitoring.

Turret cameras combine features of both dome and bullet designs. They have a rounded top like a dome but sit on a swivel base. Turret cameras allow operators to manually adjust the viewing angle without removing the camera from its mount. They work both indoors and outdoors and have become increasingly popular in recent years. Turret cameras provide flexibility for businesses that may need to adjust camera angles as security needs change.

PTZ cameras stand for "pan-tilt-zoom" and offer remote control capabilities. These cameras can move left and right, up and down, and zoom in and out from a control station. PTZ cameras work well for large areas like parking garages, stadiums, or manufacturing floors where fixed cameras cannot cover everything. An operator can watch one area, then smoothly move the camera to monitor another location. PTZ cameras typically cost more than fixed cameras but offer greater flexibility.

360-degree cameras capture video in all directions simultaneously using fisheye lenses or multiple sensors. These cameras reduce the number of devices needed to monitor a large area. They work well in retail stores, warehouses, and open office spaces. The video footage can be digitally adjusted after recording to view any angle or direction.

Practical takeaway: Match camera type to location. Dome cameras work best indoors, bullet cameras for outdoor weather exposure, turret cameras for adjustable angles, PTZ cameras for large dynamic areas, and 360-degree cameras for comprehensive single-point coverage. Consider both visibility and functionality when selecting camera types for different areas of a business.

Resolution and Image Quality Standards

Video resolution determines how clear and detailed recorded footage will be. Resolution is measured in megapixels and in terms like 720p, 1080p, and 4K. Higher resolution means sharper images where details like faces or license plates are easier to identify. However, higher resolution also requires more storage space and faster internet connections to transmit video data.

Standard definition cameras capture video at 720p resolution. This resolution provides basic monitoring capability for detecting general activity and movement. A 720p camera produces an image about 1,280 by 720 pixels. For many retail businesses, 720p is adequate for monitoring customer traffic patterns and general store layout. However, 720p may not be sufficient for identifying specific facial features from a distance. A business using 720p cameras in a small shop might clearly see a customer's face, but the same camera in a large warehouse would show the person as small and indistinct.

High definition or 1080p cameras record at approximately 1,920 by 1,080 pixels. This resolution significantly improves image clarity compared to 720p. Facial features become clearer, making it easier to identify individuals. License plate numbers become readable from reasonable distances. Many businesses consider 1080p the minimum acceptable standard for security purposes. According to industry standards, 1080p provides sufficient detail for identification purposes in most business applications. A 1080p camera in a retail environment can typically identify a person's face from across a large store.

2K and 4K resolutions represent the newest standards in surveillance. 2K resolution captures approximately 2,560 by 1,440 pixels, while 4K captures roughly 3,840 by 2,160 pixels. These higher resolutions provide exceptional clarity and allow for digital zooming without significant quality loss. A 4K camera can capture a wide area, and operators can later examine specific regions in that footage with magnified detail. High-resolution cameras work particularly well for perimeter monitoring, parking lots, and locations where identifying distant individuals is important.

Frame rate is another important resolution factor. Frame rate is measured in frames per second (fps). Most standard cameras record at 30 fps, which creates smooth video playback for human viewing. Some cameras offer 60 fps for faster-moving scenarios like monitoring building entrances during busy periods. Higher frame rates require more storage space but capture more detail of rapid movements.

Pixel density refers to how many pixels cover a specific area. Thirty pixels per foot is considered the minimum standard for facial identification in security applications. Fifty pixels per foot provides better clarity for identification purposes. A business calculating camera coverage should consider the distance between the camera and the area being monitored to ensure adequate pixel density.

Practical takeaway: Select resolution based on identification needs. Use 720p for basic activity monitoring in small areas. Use 1080p for retail and office environments where facial identification may be needed. Use 2K or 4K for large areas like parking lots or perimeters where distant detail matters. Calculate the distance between cameras and monitored areas to ensure pixels per foot meets identification requirements.

Storage and Recording Options

Video storage is a critical component of security camera systems. Businesses must decide how much footage to retain and where to store it. Recording creates large amounts of data that requires either physical storage devices or cloud-based systems. Different business needs demand different storage solutions.

Local storage using digital video recorders (DVRs) or network video recorders (NVRs) keeps all footage on equipment located at the business site. A DVR connects directly to analog cameras, while an NVR works with internet-connected IP cameras. Local storage offers several advantages: it does not depend on internet service, footage remains under the business's direct control, and there are no monthly cloud subscription fees. However, local storage requires adequate space and equipment maintenance. If a hard drive fails, stored footage can be lost unless backup systems are in place.

Storage capacity depends on several factors: camera resolution, frame rate, compression technology, and how many days of footage to retain. A 1080p camera recording at 30 fps can generate approximately 40-50 gigabytes of data per day. A business with five cameras recording continuously would accumulate 200-250 gigabytes daily. Continuous recording for 30 days would require roughly 6-7.5 terabytes of storage. Many businesses do not record continuously but instead use motion-detection recording, which significantly reduces storage needs. Motion detection records only when the camera detects activity, potentially reducing daily data generation by 70-80% depending on location.

Cloud storage services store video on remote servers accessed through the internet. Providers like Amazon, Google, and specialized security companies offer cloud storage solutions. Cloud storage advantages include automatic backup, remote viewing from any location, and no physical equipment to maintain. Disadvantages include monthly subscription costs, dependence on internet reliability, and data privacy considerations. Cloud storage pricing typically ranges from $5-50 per month per camera depending on retention length and video resolution.

Hybrid storage combines local and cloud systems. A business might store recent footage locally for quick reference while simultaneously uploading to cloud servers for backup and long-term retention. This approach provides both the speed of local access and the security of offsite backup. However, hybrid systems require more robust internet connections and create duplicate storage costs.

Retention periods vary by business type and legal requirements. Retail stores often retain 30 days of footage. Banks and financial institutions typically retain 90-180 days. Manufacturing facilities may retain 7-30 days depending on safety concerns. Some industries face regulatory requirements specifying minimum retention periods. A business should determine retention needs based on typical investigation timelines. If most incidents are reported within a week, 30-day retention is usually adequate. If investigations take longer, extended retention becomes necessary.

Recording compression technology reduces file sizes without significantly reducing image quality. H.264 and H.265 are common compression standards. H.265 (also called HEVC) can reduce file
