Most people shopping for security cameras start with resolution. It's a fair place to start, but it's rarely why a camera system succeeds or fails. The footage that actually helps you, like a clear face at the door or a readable plate at the gate, comes from good planning and a careful install. Here's what we look at when we design a camera system for a business in Waco, Temple, Killeen or anywhere else in Central Texas, and what you should expect from whoever installs yours.
1. Start with what you need to see
Before talking about cameras, a good installer should ask what you're trying to accomplish at each spot. "See who comes in the front door" calls for a different camera, lens and mounting height than "watch the whole parking lot" or "read plates at the gate." A common way to think about it:
- Overview: know that something happened and where (wide parking lot or yard views).
- Recognition: tell who a familiar person is.
- Identification: clear enough detail to identify someone you don't know. This needs the most detail on target, so it usually means a narrower view placed at entry points.
A single wide camera trying to do all three usually does none of them well. Several cameras with specific jobs almost always beat one expensive camera covering everything.
2. Detail on target matters more than megapixels
A high-resolution camera with a very wide lens spreads its pixels across a huge area, so a person 60 feet away may still only be a few pixels tall. What matters is how much detail lands on the thing you care about. That depends on resolution, lens angle and distance together. A good installer will match the lens to the job, not just pick the highest number on the box.
3. Mounting height and angle
Cameras mounted high are harder to tamper with, but too high and you get the tops of hats instead of faces. Entry cameras generally work best at a moderate height, aimed so faces are seen from the front rather than straight down. We also pay attention to the sun: a camera pointed east or west can be blinded at sunrise or sunset, which in Central Texas can be a real issue for half the year.
4. Lighting and night performance
A lot of incidents happen after dark, so night performance deserves real attention. Things to ask about:
- Infrared range versus the actual distance to what you need to see.
- Wide dynamic range for doorways and glass storefronts where bright outdoor light makes indoor subjects look like silhouettes.
- IR reflection: cameras placed too close to eaves, walls or glass can bounce their own infrared light back and wash out the picture.
- Whether some added site lighting would help more than another camera.
5. Wired, not wireless, wherever possible
For a business system we strongly prefer cameras on Ethernet cable with Power over Ethernet (PoE). One cable carries both power and video, there are no batteries to swap, and the connection doesn't drop because of interference or a weak signal. The cabling deserves the same care as any network job: outdoor-rated cable where it's exposed, weatherproof connections, proper drip loops, sealed wall penetrations, and every run tested and labeled. Long runs to the far edge of a lot may need extra planning, since standard Ethernet tops out at 100 meters.
6. Recording, storage and retention
Ask how long footage will be kept and where. Retention depends on the number of cameras, resolution, frame rate, how much motion there is and how much storage you buy. Some businesses need a week; others want a month or more. A good installer should size storage to your actual goal and explain the tradeoffs, not just pick a drive.
Also ask what happens if the recorder is stolen or damaged, and whether it's on a battery backup so a brief power blip doesn't cause a gap in recording.
7. Remote access and security of the system itself
Cameras are network devices, and they should be treated like it. Default passwords should be changed, firmware kept current, and remote viewing set up in a secure way instead of by opening ports to the internet. You should know who has access, and you should be able to add or remove users without calling the installer every time.
8. Privacy and respect for the people on camera
At J&J Technical Services we believe protecting people and protecting their rights go together. Cameras should cover your property, entrances and work areas, not places where people have a reasonable expectation of privacy like restrooms or changing areas. Audio recording has its own legal considerations, so it should never be switched on casually. Posting signage and having a simple written policy for who can view and export footage is good practice for almost any business.
9. Smarter search and alerts
Scrubbing through hours of video to find one event is slow. Modern systems can help with motion zones, smart alerts and search tools so you can find what matters faster. J&J also builds its own S.I. video security software, Sentinel, designed with the same rights-respecting approach we bring to every install. You can read more about Sentinel here, and we're happy to talk through whether it's a fit for your site.
10. Documentation and handoff
When the job is done you should get a list of cameras and what each covers, login details handed over securely, a quick walkthrough of how to find and export footage, and labeled cabling at the recorder. If an installer can't tell you which cable goes to which camera, that's a red flag.
