Security Camera Buying Guide
How to Choose the Right Security Cameras for Your Property
The best security camera depends on more than resolution. You should also consider the recorder technology, existing wiring, viewing distance, camera angle, nighttime lighting, mounting location and the type of evidence you need to capture.
For most new wired installations, SureVision IP and PoE security cameras provide the strongest upgrade path. When a property already has usable coaxial wiring and a compatible DVR, an HD CCTV replacement camera may provide clearer video without requiring the entire cable infrastructure to be replaced.
Security Camera Features to Consider
Different locations may require different lenses, resolutions, nighttime capabilities and mounting designs.
Camera Resolution
Higher resolution can provide more detail, but lens choice, distance and lighting are also critical to usable evidence.
Viewing Angle
Wide lenses cover larger areas, while tighter or motorized lenses provide more detail at longer distances.
Night Vision
Compare infrared range, available ambient light and full-color nighttime options for each location.
Audio Features
Select cameras may include built-in microphones, speakers or two-way audio for compatible applications.
Outdoor Protection
Use properly rated cameras, junction boxes and mounting accessories for exposed outdoor locations.
Security Camera Questions
What type of security camera is best for a new system?
For most new professional wired installations, we recommend compatible SureVision IP or PoE cameras paired with a SureVision NVR. The best camera style and lens depend on the location and viewing objective.
Can I replace an older CCTV camera without replacing its cable?
In many cases, compatible existing coaxial cable can continue to be used with an appropriate HD-over-coax replacement camera. The camera's video format, resolution, power and DVR compatibility should be checked before ordering.
What is a 4-in-1 CCTV camera?
A 4-in-1 camera is designed to support multiple analog-HD video formats, commonly including CVI, TVI, AHD and traditional analog. Compatibility still depends on the specific DVR and camera settings.
What is the difference between an NVR and a DVR?
An NVR is normally used with network-based IP cameras, while a DVR is normally used with cameras that transmit video over coaxial cable. Cameras and recorders must use compatible technologies.
Are all security cameras compatible with every recorder?
No. Camera compatibility depends on technology, video format, resolution, recorder capabilities, firmware and connection type. Contact us with the model number of your existing equipment when uncertain.
Can I use different camera styles in the same system?
Yes, provided the cameras are compatible with the recorder. Many properties use a mix of bullet, turret, dome, varifocal, PTZ and specialty cameras.
Do professional security cameras require monthly fees?
Our compatible NVR and DVR systems can record video locally without a required monthly cloud-storage or monitoring subscription.
