When implementing a security camera system, home and business owners should know that the system will need to be expanded or upgraded at some point. Fortunately, both analog and IP based CCTV Systems can be expanded when the need arises. However, professional grade IP surveillance systems are more cost effective to expand in order to cater to the specialized and ever-growing security demands.

Analog vs. IP Camera System Expansion

1. Channel Limitations

Analog camera systems present unique challenges when it comes to expansion in that, theseSecurity Camera System Long Island systems rely on the number of channels/cameras that the DVRs can support. Unfortunately, DVR channels are fixed, and come in multiples of 4, 8, or 16.

IP based systems do not rely on the number of channels in the NVRs or other recording systems. As such, it is possible to install or expand the system starting from one camera, to tens or even hundreds of cameras.

2. Network Infrastructure

Analog cameras must be wired back to the DVR, or other video recording system to operate. As such, adding cameras at far away locations will present the challenge of having to run wires from individual cameras, directly to the DVR.

IP surveillance systems can operate on the existing computer network infrastructure. For this reason, there is no reason to run wires back to the NVR. Users can simply plug in the IP Cameras to the nearest network hub or switch.   

3. Wireless Integration

Integrating Wireless Cameras into an analog security camera network is usually difficult. An analog security camera system can only support upto 16 Wireless Cameras, owing to the limitation on radio frequencies. In addition, users have to install the Wireless Cameras near a power source, or resort to using batteries.

Wireless IP Cameras are very easy to integrate into an existing surveillance network, owing to the compatibility in signal transmission protocols. In addition, there is no practical limit as to the number of cameras that can be installed. On the other hand, IP Cameras can be powered using the regular power supply, or through POE. Therefore, plugging in the cameras to the nearest network switch is sufficient.
