Easy to install: Most network cameras on the market are plug and play and / or very easy to follow instructions for both hardware and software end.
2. Comparatively cheaper than other security systems: Instead of paying a highly trained technician to install a CCTV complex, and ongoing maintenance paid to a disposal, you can have a network camera security system can be on your own against CCTV and traditional security systems.
3. Works with your existing computer network: If you already have a home network, then the network camera works with the settings, so you do not need to pay more for adequate security infrastructure.
4. Provides peace of mind: see your house, watch your child's room, watch your vacation home, see their pets while on vacation, etc.
5. See remote areas: as far as around the world, or your own front porch of a centralized area. There is even the chance to see their children in the nursery (depending on the nurseries policies though this is increasingly standard)
6. Flexibility: Prefer not to be tied to the security control panel or hire a full time professional security to control things, then get security alerts which can be seen from the cell phone, laptop, PDA or device, and provide multiple users access to the security of various assets.
7. Receive email alerts when motion is detected, either when someone visits your home, or when their children leave home to hang out.

Cons

1. May have poor image quality depending on model and configuration, and wireless cameras in general have poorer image quality in the lower midrange.
2. For more bells and whistles, such as sound recording, scheduled emails, and motion capture, which varies widely from model and software description.
3. Generally, outdoor surveillance equipment is more expensive, especially if you want the ability to scroll distance / tilt, zoom in, zoom out, and want a waterproof camera. However, for a home system this is probably not as urgent as opposed to a business situation.
4. Depletes networked computer, so if you do not have a fast computer, then there is the possibility of a slight slowdown in their collective resources.

Remember that despite the cons, the advantages outweigh the results as they provide a high security installation and lower maintenance costs than traditional Closed Circuit Television.
